Our CCTV Monitoring

How remote CCTV monitoring works?

A CCTV monitoring system comprises the deployment of a network of surveillance cameras in a designated area, with these cameras transmitting their video feeds to a central recording device, known as an Network Video Recorder (NVR). The recorded video can be accessed in real-time and archived for future reference. Skilled operatives at our monitoring centre monitor live video feeds and can promptly respond to security events and suspicious activities, often triggered by motion detection. This comprehensive system is invaluable across diverse sectors, including residential and commercial security, retail, and law enforcement.

Additionally, our remote monitoring service enhances security with live audible warnings to intruders on your site, and our operators assess intrusions in real-time, determining the appropriate response, including notifying keyholders or police. Our monitoring software is equipped with artificial intelligence to distinguish between people, animals, obstructions, and foliage etc, ensuring accurate intrusion detection. After each incident, you receive a detailed report summarising event details, actions taken, and outcomes. 

CrystalView Services’s monitoring provides:

CCTV monitoring is the answer to improving your employee safety and security in the workplace. CCTV cameras can provide many benefits for employees and employers, including deterring crime, providing evidence of criminal activity, and allowing for a rapid response to incidents.

One of the main benefits of monitored CCTV is its deterrent effect on criminal activity. Criminals are less likely to target your workplace if it is monitored by CCTV cameras, as they know their actions will be recorded, providing evidence against them. This can significantly reduce the risk of theft, vandalism, and other criminal activity in your workplace. Ensure your building has CCTV signage, so it is clear of the CCTV monitoring system you have in place, which is another means of deterrent.

https://www.youtube.com/watch?v=HTfDvosLhtk&embeds_referring_euri=https%3A%2F%2Fold.CrystalView Services-communications.com%2Fcctv-monitoring-improves-employee-safety-and-security%2F&source_ve_path=MjM4NTE&feature=emb_title&ab_channel=CrystalView ServicesCommunicationsLtd

Depending on the nature of your business, it can act as a safeguarding solution, for example, in schools or companies where there is an opportunity for threat or increased criminal activity. It can reassure your employees, customers, or tenants of their safety and well-being.

In addition to deterring crime, CCTV monitoring also provides valuable evidence in the event of a criminal incident. Our cameras capture high-quality footage with the ability to identify suspects and assist in prosecuting criminals. This can help to bring criminals to justice and provide closure for victims of crime.

Another benefit of CCTV monitoring is the ability to respond quickly to incidents. With our real-time monitoring, employers can be alerted to incidents as they happen, allowing them to take immediate action to address the problem. Suppose the monitoring centre sees any threat to a person or your premises. In that case, they can issue audible warnings and alert the police or key holder, minimising the impact of incidents on employees.

CCTV monitoring also helps in employee safety. Employers can monitor their workplace to ensure that the employees follow the required safety protocols and that all equipment is correctly and safely operated. This can help prevent workplace accidents and injuries, resulting in lost time, medical expenses, and legal liability.

In conclusion, CCTV monitoring is an essential solution that improves employee safety and security in the workplace. It provides a deterrent effect on criminal activity, valuable evidence in the event of a criminal incident, the ability to respond quickly to incidents, and ensures employee safety. All employers have a duty of care and should consider implementing CCTV monitoring to protect their employees and business.

Constituents of a Composite Video Signal

The composite video signal comprises several elements, including:

• Video Signal
• Horizontal Sync Pulse
• Vertical Sync Pulse

Let’s examine each of these in more detail.

The Video Signal

When light falls on a Charge-Coupled Device (CCD) chip, it instigates a charge within the pixels proportional to the light intensity. A greater amount of light corresponds to a larger charge. This charge is then converted into a video signal. The process of reading this charge varies depending on the type of CCD chip. In a composite video, the video signal has a maximum amplitude of 0.7 volts. This means the bright parts of the picture, the white elements, will have a signal strength of 0.7 volts, while the darker, black parts will register a signal of 0 volts.

Vertical Sync Pulses

A video picture comprises multiple video frames. NTSC, for instance, utilises 30 frames per second (fps), while PAL uses 25 fps. To prevent flickering, this video frame is subdivided into two fields, termed the ‘odd’ and ‘even’ fields. These fields are separated at the camera and later recombined at the monitor, a process known as ‘interlacing’ of fields.

Each frame or field concludes with a vertical sync pulse. This pulse indicates to the electronic devices within the camera and other CCTV components that the current field has ended and the next one is about to start. The pulse’s duration is dictated by the time electronic devices take to receive the next field, with an amplitude of 0.3 volts.

Horizontal Sync Pulse

A video frame consists of lines, with NTSC containing 525 lines per frame and PAL encompassing 625 lines. Each point along the line mirrors the intensity of the video signal. The conclusion of each line is marked by a horizontal sync pulse, informing the CCTV system’s electronic devices that a line has ended and the next is about to commence. This pulse also carries an amplitude of 0.3 volts.

Frequencies of Horizontal and Vertical Scanning

Let’s delve into the different frequencies within the PAL and NTSC systems:

Horizontal and Vertical Blanking

‘Blanking’ refers to the period when no picture information is being scanned and is denoted by the screen ‘going to black level’. This period must be rapid, as it’s essentially wasted time with no picture information conveyed. Approximately 16% of each horizontal line and about 8% of the vertical field is dedicated to this retrace time.

Here are the specific measurements for NTSC and PAL systems:

Horizontal and Vertical Synchronisation

The synchronisation pulse initiates the actual retrace in scanning. The horizontal sync pulse is inserted in the video signal during the horizontal blanking pulse, while the vertical sync pulse is inserted during the vertical blanking time. The frequencies for each synchronisation pulse in NTSC and PAL are as follows:

Colour Signals in CCTV

A colour video signal is akin to a monochrome signal, but with additional colour information, transmitted separately. This includes:

1. Luminance signal (Y signal): Contains the variations in the picture information as seen in a monochrome signal, reproducing the picture in black and white.
2. Chrominance signal (C signal): Contains the colour information, transmitted as the modulation on a sub-carrier. The sub-carrier frequency is 3.58 MHz for NTSC and 4.43 MHz for PAL.

In a colour receiver, the chrominance signal is combined with the luminance signal to produce a colour picture. However, in a monochrome receiver, the chrominance signal isn’t used, and the picture is reproduced in black and white.

Constructing the Composite Video Signal

The composite video comprises:

• Camera signal output corresponding to the scene’s light variations
• Synchronisation pulses for scanning
• Blanking pulses to make the retrace invisible
• For colour signals, the chrominance signal and colour sync burst are included.

Conclusion

Grasping the workings of composite video signals is critical in understanding the broader functionalities of CCTV systems. As we’ve learned, these signals are composed of various elements, all intricately working together to ensure seamless transmission from the camera to the control room. From the video signal itself to vertical and horizontal sync pulses, each component plays a pivotal role.

While the technical aspects might seem daunting at first, breaking down each part can significantly demystify the process. Whether you’re just embarking on your journey in CCTV operation or looking to refresh your existing knowledge, we hope this guide has proven informative and helpful.

The CCD Chip: An Unsung Hero in Your Camera

The CCD (Charge-Coupled Device) chip in a camera is a little unsung hero that plays a significant role in capturing high-quality images. Superior cameras typically house advanced chips endowed with innovative features like On-Chip Lens (OCL), Backlight Compensation (BLC), and excess charge drainage technology. These chips truly revolutionise your camera’s capabilities.

Deciphering Camera Specifications

When it comes to camera specifications, the jargon can often feel like a foreign language. But fear not! We’re here to help decode some of the vital elements on any camera data sheet, such as resolution, sensitivity, signal-to-noise ratio, camera voltage, chip type, and operating temperature. It’s worth noting that some data sheets offer extensive details, while others may be more limited.

All About Resolution: The Cornerstone of Image Quality

At the heart of your image quality lies the concept of resolution. Simply put, the resolution of your camera is like the sharpness of a pencil. The sharper the pencil (or higher the resolution), the clearer the picture you can draw. Resolution is measured in lines – the more lines, the higher the resolution, leading to a better image quality.

In a nutshell, resolution equals the quality of definition and clarity of a picture. This quality is determined by the number of pixels (picture elements) in the CCD chip. The more pixels a manufacturer can cram into a CCD chip, the greater the resolution will be. The relationship between resolution and pixels is like peas and a pod; they go hand in hand!

Vertical Vs Horizontal Resolution: A Quick Comparison

Resolution refers to the clarity and definition of a picture, typically defined in lines. Higher resolution equates to better picture quality, which is dependent on the number of pixels (picture elements) in the CCD chip. More pixels in the same size CCD chip result in higher resolution.

Vertical Resolution

In technical terms, vertical resolution equals the number of horizontal lines. Vertical resolution is typically capped by the number of horizontal scanning lines. For instance, in PAL, it’s 625 lines, and in NTSC, it’s 525. Here’s a fun fact: the maximum vertical resolution is .7 of the number of horizontal scanning lines! So, we get:

• PAL: 625 x .75 = 470 lines
• NTSC: 525 x .7 = 393 lines

Horizontal Resolution

When we speak of horizontal resolution, we mean the number of vertical lines. In theory, horizontal resolution can be increased infinitely, but it faces two main challenges: increasing the number of pixels in a chip may not always be technologically possible, and increasing the number of pixels reduces the pixel size, which affects sensitivity.

If only one resolution is mentioned in a data sheet, it is usually the horizontal resolution.

Measuring Resolution: Exploring Different Approaches

There are two primary methods to measure resolution: The Resolution Chart and The Bandwidth Method. Let’s delve a little deeper into both.

The Resolution Chart

Imagine focusing your camera on a chart filled with vertical and horizontal lines. The resolution is measured where the lines start merging, and they can’t be separated. It’s an easy, direct method to gauge your camera’s resolution capabilities.

The Bandwidth Method

The Bandwidth Method is like the Resolution Chart method, but it steps up a notch by measuring the electrical signal bandwidth. It takes into account the fact that the signal’s frequency increases with the resolution.

To wrap up the resolution segment, let’s keep in mind the following: While the resolution is a crucial aspect of image quality, it’s not the only one. Other factors like sensitivity, contrast, colour rendition, and signal-to-noise ratio also play key roles in determining the final image quality.

How Does Sensitivity Impact Your Camera?

Sensitivity is to a camera what the retina is to the eye. It measures the smallest amount of light required by the camera to produce a useful video signal. Sensitivity is expressed in lux (lx), the SI unit of illumination, equivalent to one lumen per square meter.

Two terms often cause confusion in this context: “sensitivity at faceplate” and “minimum scene illumination.”

• Sensitivity at Faceplate: This refers to the minimum light required at the CCD chip to produce an acceptable video picture.
• Minimum Scene Illumination: This term denotes the minimum light required at the scene to produce an acceptable video picture.

Understanding sensitivity involves knowledge of several key variables:

• Reflectance
• F-stop
• Usable video
• AGC (Automatic Gain Control)
• Shutter speed

Reflectance

Reflectance is a critical concept in cameras that relates to the amount of light a subject bounces back based on its surface characteristics. In simple terms, reflectance is the percentage of incoming light that is reflected off a particular surface.

For example, consider two very contrasting surfaces – snow and a black object. Snow, being a highly reflective surface, bounces back around 90% of the light that strikes it. This high reflectance is why snow appears so bright and visually dominant in images.

On the other hand, a black object, known for its low reflectance, returns merely 5% of the incident light. This is because darker surfaces tend to absorb more light, reflecting only a small fraction back to the viewer or camera.

These differences in reflectance can significantly influence the amount of light your camera’s sensor receives, impacting the overall exposure and quality of your image. Hence, understanding and considering reflectance while setting up your shot can greatly assist in producing well-exposed, detailed photographs.

F-stop or Lens Iris Opening

The F-stop, also known as the lens iris opening, is an essential parameter in camera specifications that significantly influences image quality. It refers to the size of the opening in the camera’s lens that allows light to enter and hit the camera’s sensor.

The F-stop is represented by numbers such as F1.4, F2.0, F2.8, and so forth. Interestingly, smaller F-stop values correspond to larger lens openings, which allow more light to reach the camera’s sensor. For instance, a lens with an F-stop of F1.4 has a larger opening and therefore admits more light than a lens with an F-stop of F2.0.

In the context of CCTV cameras, a lower F-stop value is desirable, especially in low-light situations. A camera with a lower F-stop rating is capable of capturing clearer images under less-than-ideal lighting conditions. However, keep in mind that this is one of many factors that contribute to the overall image quality of the camera.

Usable Video

Think of “usable video” as the criteria your footage must meet to serve its purpose. It’s a fluid term, shaped by what you need from the video. For example, a camera might capture an image in near darkness ? impressive, right? But if the details, like facial features, remain obscured, is the footage truly useful? Just as you’d choose the right tool for a job, it’s vital to align your camera’s capabilities with your specific needs, ensuring the video produced is genuinely ‘usable’ for its intended purpose.

AGC (Automatic Gain Control)

Imagine you’re trying to listen to a whisper in a quiet room. You’d naturally strain your ears to catch every word. That’s essentially what the AGC does for cameras. It’s an electronic circuit that boosts video signals, especially in low-light scenarios, ensuring you get a clearer picture. However, just as straining too hard might make you hear things that aren’t there, relying excessively on AGC can add unwanted “noise” to your video. The trick is finding the balance for the crispest image without compromising its authenticity.

Shutter Speed

The shutter speed influences the camera’s sensitivity by determining how long the CCD chip is exposed to light. A slower shutter speed increases exposure time, enhancing sensitivity, but it can also lead to motion blur in moving objects. Conversely, a faster shutter speed reduces motion blur but may compromise sensitivity, particularly in low-light conditions.

Camera Voltage: The Lifeblood of Your Camera

Camera voltage is as crucial to your camera as blood is to your body. Cameras operate on different voltages, often between 9-12V DC or 24V AC. It’s essential to match the power supply voltage with the camera’s operating voltage to avoid damage and ensure optimal performance.

Chip Type: The Brain Behind the Camera

The chip type in a CCTV camera can significantly impact its performance. The most common types are CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor). CCD chips offer better image quality and low noise levels but are typically more expensive. CMOS chips are less expensive and consume less power but often suffer from lower image quality and higher noise levels.

Operating Temperature: The Climate Inside Your Camera

Just like humans, cameras can also be sensitive to temperature. Most cameras are designed to operate within a specific temperature range, usually between -10 to 50 degrees Celsius. Operating a camera outside this range can lead to poor performance or even damage.

Final Thoughts

Understanding CCTV camera specifications is crucial to ensure the system meets your specific needs. High-resolution cameras can capture clear images, but they may require more light to function effectively. Conversely, a camera with excellent sensitivity may operate well in low-light conditions, but it may not provide high-resolution images.

Remember, these specifications only tell part of the story. It’s equally important to consider the actual usage environment, such as lighting conditions, distance to the subject, and expected subject size. Also, pay attention to other features such as zoom, tilt, pan capabilities, and automatic focus, which can further enhance your CCTV system’s effectiveness.

The surge in technological advancements has propelled the world towards intelligent systems that significantly enhance safety, security, and efficiency. One such technology that has proven to be a game-changer is Automatic Number Plate Recognition (ANPR) cameras.

Imagine a system that instantly recognises every vehicle passing by, reading and recording its license plate, all while operating under challenging conditions such as low light or poor weather. This isn’t a thing of the future, but the reality of ANPR technology. ANPR cameras are versatile and powerful, employed in a plethora of applications, from traffic management to crime prevention and beyond.

This article delves into the nitty-gritty of ANPR cameras, elaborating on their workings, benefits, and wide-ranging applications.

https://www.youtube.com/watch?v=HTfDvosLhtk&embeds_referring_euri=https%3A%2F%2Fold.CrystalView Services-communications.com%2Fcctv-monitoring-improves-employee-safety-and-security%2F&source_ve_path=MjM4NTE&feature=emb_title&ab_channel=CrystalView ServicesCommunicationsLtd

How Does an ANPR Camera Work?

ANPR cameras work by capturing images of license plates using optical character recognition technology. They usually comprise of two components – hardware and software. The hardware includes the camera, lens, and the lighting often using infrared, which allows for visibility in any weather or lighting conditions. The software is where the OCR technology comes into play.

When a vehicle passes in front of the camera, it captures an image of the license plate. The image is then processed using algorithms that can identify and isolate the license plate section of the image. The software then analyzes the image to extract the characters (numbers and letters) on the plate. The extracted information is then stored or used in real-time, depending on the purpose of the system.

You can learn more about how CCTV cameras work in this helpful article.

Key Applications of ANPR Cameras

Traffic Management and Control: With ANPR, traffic flow can be monitored and controlled more effectively. For instance, in case of traffic rule violations such as speeding or going through a red light, the camera can capture the offender’s plate number, which can be later used for enforcement.

Parking Enforcement: In private or public parking lots, ANPR cameras can be used to manage parking occupancy, duration, and violations. The cameras can record the time a vehicle enters and exits the parking lot, allowing for efficient management and billing.

Security and Surveillance: ANPR cameras can be an effective tool in identifying and tracking stolen vehicles or those involved in criminal activities. When integrated with a database of stolen or wanted vehicles, the system can alert security personnel or law enforcement when a match is found.

Toll Collection and Congestion Charging: For toll roads, bridges, or congestion charging zones, ANPR can automate the collection process. Vehicles passing through are identified, and charges can be applied without the need for manual operations or physical toll booths, improving efficiency and reducing congestion.

Integrating ANPR with Other Systems

The usefulness of ANPR technology increases when integrated with other security or traffic systems. For instance, ANPR can be combined with CCTV surveillance systems for broader security coverage.

In September, CrystalView Services was invited to tender for the CCTV Maintenance of each campus of the University of Essex, situated at Colchester, Southend, and Loughton within Essex. The University required a CCTV maintenance company to cover the servicing of all CCTV equipment.

Providing CCTV maintenance for the University of Essex, Colchester

Located in the historic 200-acre Wivenhoe Park and home to 15,000 students, the Colchester Campus is the largest of the three sites, making the site’s security a priority. The 210-camera CCTV system includes a mixture of Axis, Bosch and Mobotix cameras and encoders across the Colchester campus consisting of:

• analogue cameras
• IP cameras
• ANPR cameras
• MultiStream cameras

Maintaining Southend’s CCTV Systems

The Southend-on-Sea campus spans across seven miles of coastline and is home to East 15 Acting School, the School of Health and Social Care, the Department of Psychosocial and Psychoanalytic Studies, and Essex Business School.

The CCTV system at the Southend campus uses 55 Mobotix cameras, which is operated 24/7 from a centralised location consisting of:

• IP cameras

CCTV Maintenance Loughton:

London's largest open space borders the campus, Epping Forest, just minutes from Loughton. The Loughton campus operates both Hikvision and Axis CCTV cameras systems across multiple buildings on site, and these 26 cameras consist of:

• IP cameras

The CCTV maintenance contract was to include reactive call-outs (with different priority responses depending on the severity of the fault), preventative maintenance visits to check the CCTV equipment is in full working order, CCTV repairs and new CCTV installations, the ordering of new CCTV system equipment and a critical spares plan. The University required the contractor to be NSI accredited and an approved supplier through the ESPO framework.

This framework gives the client immediate confidence that the suppliers have already been vetted to a high standard. To be awarded the framework as an approved supplier, CrystalView Services had to provide extensive evidence that we operate safely, have the correct insurance levels, demonstrate previous evidence and technical knowledge, and carry out projects and maintenance to the highest standards.
This, along with our industry-leading accreditations and experience, enabled CrystalView Services to meet the demanding requirements and was awarded the CCTV maintenance contract for the University of Essex. The works are due to commence in January 2022.

CCTV stands for closed-circuit television and usually consists of a network of 2 or more CCTV cameras that connect to a recording device and storage system. The first documented use of CCTV systems was in 1942, but it wasn't until the 1990s that it became commonplace. 

Currently, as many as 5.2 million CCTV systems are operating in the UK. This number will continue to increase as businesses seek higher levels of security through CCTV surveillance.

What is the purpose of CCTV?

CCTV systems enable business owners to monitor their premises? interior and exterior closely. You can also use CCTV for home security if you work from home. This is particularly essential if you store expensive, high-tech equipment that would be difficult to replace. 

In some cases, they can mean the difference between solving a criminal case and coming to a dead end.

Recent advancement in technology has allowed for the development of new, high-resolution camera lenses with incredible zoom capabilities. This detail allows them to identify the unique facial features of the culprits. 

Automatic Number Plate Readers (ANPR)

However, an even more remarkable feature is that specific models of CCTV can capture vehicle number plates. For example, an Automatic Number Plate Recognition camera can read vehicle registration plates and create location data. ANPR works by using a camera that is linked to a computer. Each time a vehicle passes the camera, the number plate is 'read? by the PC and the Vehicle Registration Mark is recorded.

If the police have reasonable cause to suspect criminal activity, they can request the details of the name the vehicle is registered to from the DVLA. You can also determine how old the car is, the colour and which year it was registered in.

Therefore, even if the intruder escapes, you can determine the transportation they use. In addition, the police can enter the number plate on their system to find the vehicle's make, model and year of purchase. Intelligent video analytics can recognise unique behaviours that have been programmed in, such as 'person moving from vehicle to vehicle.' 

Remote CCTV Monitoring

Overall, if you have a CCTV system fitted in your business, you can monitor activity at all times. At CrystalView Services, we offer remote CCTV monitoring from a UK alarm receiving centre (ARC). They will monitor your premises via your security cameras 24/7, 365.

The ARC will have the ability to:

• Inform you of an intrusion
• Use loudspeakers to warn criminals, e.g. 'you are being recorded on CCTV', 'the police have been called'
• Contact the police and/or emergency services

Our CCTV monitoring is unique. We use video analytics to help improve accuracy within the surveillance process. This can help remove up to 90% of false alarms, allowing you to focus on real threats.

Once the alarm is sounded, the ARC will receive images from the camera on their screen. Then, they will decide the best course of action. This takes the pressure off whilst keeping you in the loop; you can visit the site as soon as it is convenient for you. In addition, we can design and install a CCTV control room in your desired location.

By investing in security systems, suspicious behaviour can be reported, criminals can be caught in the act, and criminal behaviour is often deterred altogether.

What are the benefits of CCTV?

Decreased Criminal Activity 

Intruders often look for premises that they perceive to be an 'easy target'. They do not want to draw any attention to their behaviour. By making sure your CCTV system is clear and visible, you warn potential criminals that your business takes security seriously and will not hesitate to prosecute guilty individuals. 

The College of Policing found that crime taking place in local car parks decreased by 37% after the installation of new CCTV security systems. In areas with drug-related crimes, these decreased by 20% and vehicle and property crime went down by 14%. Additionally, CCTV was found to be increasingly effective when implemented along with other deterrents such as improved lighting and alarm systems. Here, crime decreased by 34%.

Reduced Insurance Premiums

A major benefit to all businesses, no matter their size, is that CCTV installation is cost-effective. Most insurance companies across the UK recognise and value the benefit of CCTV systems to businesses. It reduces your security risk, therefore reducing the cost of your insurance. Over time, this can save a business a significant amount of money.

Evidence for Insurance Claims

Additionally, CCTV makes it much easier to provide evidence alongside an insurance claim. This way, you can protect your business and your employees by ensuring you claim is backed up with reliable footage.

True Peace of Mind

By installing a CCTV system, you can monitor your business anytime from anywhere. This means that when you are not on-site you can still view your premises from all angles. For example, over the Christmas period when many businesses are closed, you can still check that everything is well.

Monitor Staff Performance

This advantage is particularly important for larger businesses who wish to track the behaviour and performance of their employees. They can check punctuality, attendance and monitor time spent on certain tasks. It can also help to ensure they always behave professionally. You may wish to use footage during training sessions to show examples of good vs poor behaviour.

Monitor Staff Safety

CCTV can help make sure staff follow your businesses safety procedures at all times. If an accident occurs, you can use the footage captured to make an insurance claim if necessary.

Types of CCTV

Wired

These systems are the most traditional kind of CCTV, primarily used on large premises. A cable is used to connect the camera to a recording device, the recording device is of course connected to the router. Alternatively, a power over the ethernet cable can be used to provide both power and an internet connection in just one cable. This offers a cleaner, tidy installation process. 

Usually, these are more reliable as they are not subject to interference from wireless signals. You can be certain they will be able to record 24/7.

Wireless

Wireless CCTV works by connecting to your Wi-Fi network and transmitting security footage from your camera to your recording device. You may access the captured footage by using a built-in device or cloud storage which will allow you to watch from anywhere with an internet connection. 

As they connect to your Wi-Fi, the installation process is quick and smooth in comparison to wired CCTV. This is ideal if your business is operating in a temporary location as they are easy to set up, move or take down. However, these systems still require a wired power cable. You will need to bear this in mind when choosing a location for mounting.

CCTV Installation

At CrystalView Services Communications, our experienced engineers will ensure that your business has the best CCTV camera type to suit the premises. Also, they will check that you have an appropriate amount of cameras to cover the space required. 

As businesses will usually want their cameras to be obvious to intruders, if you wish for some cameras to be installed discreetly that is not a problem. Speak to your engineer upon arrival to ensure you receive the bespoke installation you require. 

Next, it will be up to you and your colleagues to select the prime locations for your cameras. The engineer will help ensure that the cameras are not hindered by reflections or blind spots. 

In addition, you must be careful not to breach the privacy of any neighbouring buildings. Let them know about the CCTV installation in advance so that they are aware. It is illegal to record audio on CCTV in the UK, so make sure audio is disabled on your devices. Ideally, your CCTV system will only capture images within the boundaries of your businesses? private property. 

If you are capturing footage outside of your private property, you need to take certain steps to comply with data protection laws. For example, if you wish to record the public footpath outside your premises, you need to put signs up to state that recording it taking place and why. 

Lastly, make sure that only authorised individuals have access to the footage e.g. security staff and the CEOs. If recordings enter the wrong hands, you could be in breach of the data protection act. Add an extra layer of security by protecting the footage with a secure password.

How much will CCTV cost? 

The cost of your CCTV installation is entirely dependent on the size of your business and the level of detail you wish to capture. Naturally, the more cameras you install, the higher the cost.
