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.

Fire batts are extremely effective tools for preventing fires ? but what is a fire batt exactly? 

The brief lapse of attention that allows a fire to start can lead to devastating consequences, destroying property and endangering lives. Although fire services can respond to such incidents, they might not always be able to prevent substantial damage. Therefore, for property and business owners, proactive fire prevention and protection systems are indispensable. One such system that has proven highly effective in mitigating fire damage is the fire batt.

In this comprehensive guide, we delve into the realm of fire batts – their composition, functions, and their pivotal role in passive fire protection systems. If you’re contemplating enhancing your property’s protection against fire, you’ve come to the right place.

An Introduction to Fire Batts

A fire batt is a slab made of robust mineral fibres, coated with an intumescent mastic – a type of adhesive that expands when exposed to heat, thereby providing a protective layer to the material underneath. These are primarily used to seal gaps and openings in walls, floors, and ceilings, essentially acting as fire barriers.

Fire batts, typically composed of fibreglass or mineral wool, are manufactured and supplied by reputable companies like Quelfire, Polyseam, Rockwool, and Firetherm, to name a few.

It’s worth noting that the installation process, which involves meticulously cutting and joining different pieces to form a single slab, is critical to the overall effectiveness of the fire batt. Given the fact that fires cause molecules to heat and expand, any improperly installed batt could compromise the fire resistance of the area, leading to the spread of fire and smoke.

The R-Value: Measuring Thermal Resistance

Just as with other types of insulation, the effectiveness of fire batt insulation is gauged on the r-value scale, a measurement of the material’s thermal resistance. The higher the r-value, the better the material is at controlling heat. However, a higher r-value also corresponds to a higher price point.

2. Choose the right camera for the location

Although many cameras are promoted as ANPR cameras, only a relatively small proportion have all the technical features necessary to ensure optimal plate reading capability.

An ANPR camera will require infra-red (IR) illumination, and a very fast shutter speed (1/10,000 to 1/20,000 second). The IR lamp should be shuttered in synchronization with the camera to provide a maximum burst of light to illuminate the number plate. Also, ensure that your camera has a zoom lens so that the angle of view can be adjusted precisely to obtain the best possible angle of view (preferably via motorized control to save having to open up the camera case each time you want to tweak the lens angle).

Many organizations also want a good colour image of the vehicle and perhaps images of the occupants. A good way to achieve this is by using more than one camera per traffic lane, with an infrared camera to recognize the plate and associated colour overview cameras to capture the vehicle or occupants. Technically, this is a best approach.

3. Site the camera well

The camera needs to be installed level and should view the vehicle from dead ahead if possible. If there is no suitable mounting point, consider a column with an extended arm to bring the camera out above the traffic, but bear in mind the clearance required for the tallest vehicles using the roadway.

Do not try to capture the vehicle from behind as accuracy will be reduced (amongst other things car plates are often obscured by bicycle racks or tow bars, whilst lorry trailer plates are usually fixed by elastic cord over the characters).

The ideal camera height is 0.9m above ground level. It should not be too high in relation to the recognition point; try to keep the maximum vertical angle below 30 degrees. However, if tail-gating is also problem that cannot be solved by other means; you may need to compromise between these two requirements since a greater angle will improve tailgating problems. Be aware that increasing the vertical viewing angle also increases the need for shorter exposure times.

4. Zoom in close

Most initial problems with ANPR systems are due to the camera not having a close enough view of the vehicle. As a general rule, the vehicle should be as wide as the screen width when displayed on a monitor, with a car's wing mirrors touching each edge of the image.

To achieve the best viewing angle, it is important to choose ANPR cameras with variable focal length or zoom lenses. Using a camera with remote control of lens zoom will also make camera set-up far quicker, easier and more accurate.
Whilst some ANPR systems can work with smaller plates than this, you can be sure of success if you stick by this rule. exposure times.

5. Avoid blurred images

A sharp image of the license plate is essential if you wish to achieve the highest success rate. Ensure that the camera is focused on the chosen recognition point.

Only use ANPR cameras with high shutter speeds. To avoid mis-reads due to blur, shutter speed should be set to 1/20,000 second. Also, ensure that the ANPR camera has a pulsed LED infra-red illuminator. This will ensure maximum light reflects from the number plate ensuring that even vehicles are travelling at speed in darkness they can be read reliably.

6. Driver images

If you wish to obtain driver images and your location is a site entrance, you can successfully obtain an image of each driver by employing two cameras. One camera views the plate whilst the second views the driver through either the side or front window. Because of the reflective glass, it is necessary to use a polarizing filter on the camera viewing the driver. This will replace the problem of reflections in the windscreen making it difficult to see the driver.

7. Software ? Start with the Basics

If you need a central system which can capture records from multiple locations in order to provide unified data, either now or in the future, check that the software can be networked. It is important to be sure whether the system could possibly expand to multiple workstations or multiple sites later on ? if it might, it makes much more sense to choose a system which has a network option now and avoid problems with re-configuring the system and retraining staff.

Recognition accuracy is single most contentious issue with new systems. Try and ensure that the accuracy stated is genuine; ask how it was measured and whether it has been verified. Also try and establish if there is any reason why your system will not reach the stated accuracy figures.

The system provider should make you aware of any design aspects which will reduce the final accuracy.

Finally, consider how you will want the statistics and data collected by the ANPR system to be presented. Tables of data are fine for many requirements, but would some in your organisation prefer to have the data presented graphically for easier interpretation and more instant clarity. Make sure you're aware of the presentation capabilities of the ANPR software package you're considering.

8. Keep your data secure

The personal data you capture needs to be stored securely and only for a limited period, in order to comply with the Data Protection Act.

Ensure the ANPR software you choose uses file encryption to prevent unauthorized access to the personal data when stored (or that some other reliable means of securing the data is provided).

Unless you are prepared to regularly check and manually delete records, also ensure that timed automatic deletion is included to so that recognition records will not be stored beyond your maximum period.

If you intend to use recognition images as evidence, watermarking is an important feature that verifies a digital image has not been tampered with since it was first captured.

A secure method to enable operators to log on to the system is essential for protecting access to the records from unauthorized users. A detailed audit trail is also a major benefit as it enables a retrospective check on who did what and when.

Ensure that the ANPR system settings and historic ANPR data are backed up ? preferably on solid state media (e.g. compact flash, SD card etc.) rather than a hard disc. Hard discs are more prone to failure than other IT components because they have moving parts. Systems which are reliant on hard discs are inherently less robust than those relying on solid state components.

9. Don't use a domestic platform for an industrial application

Do not choose an ANPR system which runs on windows software on a desktop PC unless you are willing to accept an ANPR system which crashes as frequently as a standard PC, and suffers from software bugs and viruses common with standard PCs. An industrial system offering embedded software, uninterruptible power supply (UPS) back up and solid-state data back-up will provide maximum resilience.

10. Try before you buy

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.
