The security of CCTV systems is among of the most widely used and efficient security tools within the UK. Particularly in the turbulent security context, their numerous benefits include being a powerful criminal deterrent as well as a reliable way of monitoring and, in the event of a need an excellent source of information for forensic analysis.
CCTV cameras were initially designed solely to record video however, the sheer quantity of cameras and the sheer volume of data and the police and security demands have prompted manufacturers of CCTV equipment to step up their game and offer a wide range of features that are advanced.
Installation of CCTV can be a challenge due to the numerous laws and situations you need to consider. Let our experts take care of the task for you!
Certain of these options are useful to everyone CCTV users and are recommended (or necessary) from Home Office Home Office to anyone who wants to set up the CCTV camera. Other features are only relevant to a select group of users.
Each of them are, however, a part of the final cost of your device. Understanding these factors can assist you in making the right decision — so let’s take a look at the most significant ones and find out which ones are most essential or useful.
Benefits of CCTV
1.Motion Detection
On-demand recording is among the most effective features of the latest CCTV systems. It is especially useful in infrequently-accessed areas, where continuous recording throughout the day will provide you with tens of hours of footage of a door and maybe thirty seconds of people coming and going.
CCTV systems that have motion detection capabilities permit you to set up your camera to record only after it detects motion in the field of view. This means that only footage with relevant information will be saved. This helps you save the cost of storage backups and archiving. It also makes it simpler to search and retrieve information whenever you need it.
2. Infra-Red Lighting
Like all cameras CCTV cameras can only capture objects if they have some degree of illumination upon them. But, the light must not be part of the visible spectrum.
Infra red CCTV cameras are equipped with infra-red LEDsthat can be used to light the objects within their area of vision. This lets CCTVs “see” in the dark as well.
There are many cameras advertised in the form of “day/night CCTV camera”. Day/night CCTV cameras detect the level of ambient light and then turn the LEDs in Infra-Red on and off according to the need.
Infra red cameras are made of cheap components that are readily available, therefore features that are infra red do not have to increase the camera’s cost. But, it is important to steer away from the less expensive models, which typically lack adequate illumination levels or are unable to alter the level of illumination on a regular basis (or in any way) and result in low-quality footage.
3. Two-Way Audio
Two-way audio is among the most under-appreciated advanced features of CCTV. Two-way audio allows the person within the control area to talk with the person who is in the front of the camera. The conversation can be stored and archived just as any other type of video.
Two-way audio is mostly useful for access control systems that use interactive technology in which access to restricted areas must be verified or operated by a person. But, it can be useful in other circumstances too.
It allows for instance, humans to instantly be aware of and comprehend access attempts, which makes it simpler to distinguish the difference between a genuine and malicious attempt at access. It can also be a great alternative to an intercom system, reducing complexity and making maintenance easier.
4. Automated Number Plate Recognition
Automatic Number Plate Recognition (ANPR) is a cutting-edge CCTV feature that allows software for video analysis to instantly read and detect the number plates on vehicles.
The worth of this feature is not so much in the functionality it self (which is intriguing however, it is essentially nothing more than a test for computer vision) because of the integration of it with archiving access management, parking and management software, but in the analytical value of the data it will offer.
It is possible to use ANPR to:
Access to parking
Reduce transit times
Maintain accurate, real-time information regarding the amount of parking spaces utilized and by who.
Log access and control of the parking space of a building.
If you require this feature, ANPR is a feature worth looking into.
Be aware, however the fact that ANPR is as complicated as it is practical. It is not just a matter of the highest quality imaging equipment and cameras, but they also must be set up in a way that guarantees proper lighting, field-of-view, and distance parameter.
The Home Office maintains an excellent guide to the installation and performance evaluation of ANPR systems that you can utilize, along and with the service providers to choose the best cameras, install, test and commission the best CCTV cameras.
5. Recognition of facial features Recognition
Facial recognition does to human faces the way ANPR is to number plates on vehicles It allows the CCTV surveillance system identify the face of a person to an internal database that tells you who has just passed by the camera.
Facial recognition is an extremely effective CCTV feature that is employed in numerous locations where security or customer service are of the utmost importance. It can be utilized for example to track and identify guests who are VIP in casinos or hotels — or, similarly, to recognize individuals who aren’t permitted to enter the premises of a business or to identify suspected criminals.
Face recognition using CCTV is a complicated issue However, this is a major reason why it has two consequences.
The first issue is cost. Facial recognition is a high-end feature, and manufacturers might not have to charge an extra fee for it, however the equipment that supports it is expensive of the budget-friendly gap.
The second is accuracy. Recognizing human faces is so complex that even biological systems fail at times.
We humans can sometimes confuse a stranger with an acquaintance, for instance. Computers are much more adept at this. They can be accurate often however, they will also hit false positives (confuse an unknown person with an individual they know) as well as False negatives (failing to identify someone who is well-known by them).
The facial recognition feature of CCTV isn’t yet at a point where you can trust it in total. It could make your employees’ work much more efficient, but it can’t take the place of it.
6. Additional Video Analytics features
APR and facial recognition are among the most advanced video analytics options that CCTV systems can offer. But, some systems include other valuable video analytics functions like:
Loitering detection: Some CCTV systems are able to detect an object that is stationary and is in the camera’s field of view for more than a certain duration. This is used to identify unauthorised entry, park in restricted areas , as well as other forms of suspicious behavior.
Tracking and classification of objects The majority of CCTV cameras can identify and categorize objects into diverse types (such such as “persons” or “vehicles”) in addition to monitor their movements across their fields of view and even across several cameras.
Video analytics for CCTV is an extremely dynamic fieldthat has witnessed rapid development of many of advanced capabilities. But their precision and reliability vary a lot in the portfolio of a single manufacturer. If you are looking for a specific type of video analytics, it’s recommended to conduct some tests before committing to using a specific CCTV camera.
7. Real-Time Alerts
Real-time alerts (sometimes known as push notifications) are a relatively recent feature on camera systems that are IP enabled. CCTV systems that can support this feature are able to send an alert to a mobile or tablet in response to specific situations, like detecting motion.
Real-time alerts are an extremely beneficial CCTV feature, but they must be implemented with care.
First the system that sends numerous unnecessary alerts can quickly drown unnecessary alerts within a stream of irrelevant content that tends to reduce security, not improve security. This is because the majority of people will end up believing that each alert is fake.
Additionally, push notifications may appear straightforward but they’re based on a complicated cloud technology. Some models depend on their infrastructure from their manufacturers to transmit the notifications to your devices and make your uptime and security. Other models allow you to set up your own infrastructure making you less dependent on third-party software, however this infrastructure remains your responsibility to set up and, more importantly for security.
8. Cloud Storage
Storing CCTV information in a safe and redundant way that provides quick and effective access to camera information is among the biggest challenges CCTV owners face.
Cloud storage is targeted at two kinds of users:
Users who have a significant number of streams and the infrastructure that supports them is too big and complex to manage regardless of dedicated resources in IT
Users who have a small number of streams to handle and only a few advanced requirements, the cost of an in-house, dedicated infrastructure to safe storage and backup are difficult to justify.
Cloud storage is a feature of CCTV systems utilize cloud storage resources in order to save and access information. The cloud storage system will take over the responsibility of maintaining a safe and redundant storage system, with all the benefits and disadvantages that follow.
CCTV cloud storage from trusted partners offers the most advanced encryption high availability and effective backup capabilities that usually surpass what small and medium enterprises are able to afford.
But that some of the systems’ security remains dependent on your own security procedures For instance it is possible for an attacker to get access to your footage using weak passwords. Cloud storage can also be the trade-off between maintenance of infrastructure and costs, and vendor autonomy; a specific cloud service is only compatible with certain CCTV cameras. If it’s operated by a specific manufacturer that is, it will most of the time be able to work with only the cameras of that company.
9. Wireless Connectivity
In the past, CCTV cameras relied on wire connections, principally due to wireless protocols being deemed to be either unreliable or slow to be used for monitoring video in real-time. It’s not the case anymore, and most CCTV cameras have wifi connectivity as an alternative. Wireless CCTV installation has many advantages.
Wireless CCTVs make use of Wi-Fi for communication with the security system in general They don’t require any cables for data. This greatly simplifies your security infrastructure (and the installation process! ) as well as improve the reliability of your security system, because one less cable means one less chance of failure.
But, wireless CCTV does require power cables and the entire traffic has to be flowing and you’ll need a data network that is able to allow for continuous video streaming as well as an access point that wirelessly connects the data network and the cameras will be required.
Conclusions and Recommendations
Modern CCTV systems offer many options that go beyond video recording and monitoring. CCTV cameras include video analytics capabilities like ANPR as well as facial recognition as well as object recognition, in addition to different monitoring and storage features like the cloud and live-time notifications.
Based on the needs of your company the importance of these features could vary in importance from “nice features to own” up to “critical”. However, even if they don’t add anything to the price however, they’re not a complimentary lunch. Using these functions can be accompanied by their own set of technical, and occasionally legal issues.
