The security of CCTV systems is among of the most widely used and effective security devices within the UK. Particularly in the turbulent security situation, their many advantages include their effectiveness as a security measure, as well as a reliable way of monitoring and, should the need arise to collect evidence for forensic purposes.
The cameras originally were designed only to record video however, the sheer quantity of cameras and the amount of data recorded, as well as police and security demands have prompted manufacturers of CCTV equipment to increase the stakes and offer a wide range of features that are advanced.
The installation of CCTV isn’t easy because of the many rules and scenarios to consider. Let our experts take care of the CCTV installation for you!
Certain features are applicable to everyone CCTV users and are recommended (or necessary) to Home Office Home Office to anyone who wants to set up an CCTV camera. Some are only applicable to a select group of users.
Each of them all contribute to the final cost of your device. Understanding these factors can assist you in making the best choice, so let’s take a look at the most crucial ones and discover which ones are most essential or useful.
The advantages of CCTV
1.Motion Detection
On-demand recording is among the most beneficial 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 feature let you set your camera to begin recording only after it detects motion within the field of view. This means that only footage with relevant information will be saved. This can save you the cost of storage backups and archiving, as well as making it simpler to search and retrieve information whenever you require it.
2. Infra-Red Lighting
As with all cameras, CCTV cameras can only capture objects if they have some quantity of sunlight shining upon them. But, the light should not be visible in the spectrum.
Infra red CCTV cameras are equipped with infra-red LEDsthat can be used to illuminate the objects that are in their view. This lets CCTVs “see” at night as well.
It is common to see these cameras advertised by the name of “day/night CCTV camera”. Cameras for day/night automatically recognize the amount of light in the environment, and then turn the LEDs in Infra-Red off and on as required.
Infra-red cameras for CCTV use inexpensive components that are widely available, so the capabilities of infra-red do not need to increase the camera’s cost. But, it is important to steer away from the less expensive models, which typically aren’t sufficiently lit, or are unable to alter the level of illumination in a controlled manner (or even adjust it) which can result in poor quality footage.
3. Two-Way Audio
Two-way audio is among the less well-known 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 itself is saved and archived as any other type of video.
Two-way audio is most commonly used for access control systems that use interactive technology that require access to restricted areas must be verified or managed by a human. It can also be used in many other scenarios too.
It allows for instance, humans to quickly be aware of and comprehend access attempts, which makes it simpler to distinguish the difference between a genuine and fraudulent attempt to gain access. It also serves as a suitable alternative to an intercom system, which reduces the complexity of maintenance and making it easier to maintain.
4. Automated Number Plate Recognition
Automatic Number Plate Recognition (ANPR) is a sophisticated CCTV feature that lets video analysis software automatically read and recognize the number plates of vehicles.
The benefit of this system is not so much in the function it self (which is fascinating but is otherwise nothing more than a test of computer vision) as it is in the integration of it with archiving access management, parking and management software, as well as the value of analytics in the data it will offer.
You can utilize ANPR to:
Access to parking
Reduce transit times
Make sure you have accurate, current data regarding the number of parking spaces utilized and by who.
Log access and control of the parking space of a building.
If you’re in need of this feature, ANPR is a feature worth looking into.
Keep in mind, however it is true that ANPR is as intricate 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 will ensure the correct lighting, field of view and distance parameter.
The Home Office maintains an excellent guide to installing and performance analysis of ANPR systems that you can consult, in conjunction and with the service providers to choose to install, test, and commission the best CCTV cameras.
5. Recognition of facial features Recognition
Face recognition can be to human faces the same way that ANPR is to car number plates as it allows an CCTV security camera to identify faces to an internal database that tells you who was in front of the camera.
Facial recognition is an extremely effective CCTV feature that can be utilized in a variety of situations where security and customer service is of paramount importance. It can be utilized for instance to track and identify guests who are VIP in casinos and hotels as well as to identify individuals who aren’t permitted to be on premises of a company or to identify suspected criminals.
The facial recognition technology used in CCTV is a complex issue however, and it has two major implications.
The first issue is cost. Facial recognition is a high-end feature, and manufacturers might not be required to charge for it, however the hardware used to support it is priced on the higher end of the budget-friendly gap.
The second is accuracy. Human faces are an extremely difficult task, and even biological systems fail at times.
Humans can also confuse a stranger with an acquaintance, as an example. Computers are more skilled in this regard. They are able to make things work often however, they will also hit false positives (confuse an unknown person with the person they are familiar with) as well as fake negatives (failing to recognize someone who is well-known by them).
CCTV facial recognition isn’t yet at a level where you can trust it completely. It could make your employees’ work much simpler, but it is not able to substitute for it.
6. Additional Video Analytics features
The facial recognition feature and ANPR are among the most advanced video analytics options that CCTV systems provide. But, some systems provide other video analytics functions that include:
Loitering detection: Some CCTV systems are able to detect a stationary object which is in the camera’s field of view for more than a certain duration. This is utilized to determine unauthorized entry, park in prohibited areas , as well as other forms of suspicious behavior.
Tracking and classification of objects Tracking and classification of objects: a variety of CCTV systems are able to detect and classify objects across different types (such for “persons” or “vehicles”) in addition to monitor their movements across their fields of view as well as across multiple cameras.
Video analytics for CCTV is an extremely dynamic fieldthat has witnessed rapid development of many of advanced options. However, their precision and reliability vary a lot in the portfolio of a single manufacturer. If you require a specific category of video analytics it’s usually recommended to conduct some tests prior to 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 with this feature are able to send an alert to smartphones or tablet when they detect certain circumstances, such as the detection of motion.
Real-time alerts are an extremely beneficial CCTV feature, however it must be used with caution.
First the system that sends numerous unnecessary alerts is likely to quickly displace irrelevant alerts in a sea of irrelevant information — which can reduce security, not increase security. As a result, the majority of people will end up thinking that every alert is fake.
Additionally, push notifications may appear straightforward but they’re based on extremely complicated cloud technology. Some models depend on the infrastructure of their manufacturer to transmit the notifications to your devices and make you reliant on their uptime and security. Some models let you deploy your own infrastructure making you less dependent on third-party software, however this infrastructure remains your responsibility to use and, in particular for security.
8. Cloud Storage
The storage of CCTV data in a safe and redundant way that provides quick and effective access to camera information is among the toughest challenges CCTV owners face.
Cloud storage is mostly targeted at two kinds of users:
Users with a huge number of streams and the infrastructure that supports them is too vast and complicated to manage and even with IT-specific resources
Users with a few streams to handle and only a few advanced requirements, therefore the costs of an in-house, dedicated infrastructure to backup and storage that is secure aren’t easy to justify.
Cloud storage is a feature of CCTV systems can make use of cloud storage in order to save and access information. It is a way of outsourcing the job of maintaining a safe and redundant storage infrastructure with all the benefits and disadvantages that follow.
CCTV cloud storage provided by reputable partners utilizes the latest encryption with high availability, as well as efficient backup features that generally exceed what the majority of small and medium enterprises are able to afford.
But that some of the systems’ security remains dependent on your security habits For instance it is possible for an attacker to be able to access your video when you have weak passwords. Cloud storage is also the trade-off between maintenance of infrastructure and costs, as well as the independence of the vendor; a particular cloud storage platform is only compatible with certain CCTV cameras. If it’s operated by a specific company and brand, it will most of the time use only the cameras of that company.
9. Wireless Connectivity
Traditionally, CCTV cameras relied on wire connections, principally due to wireless protocols being deemed to be either unreliable or slow for monitoring of video in real time. It’s not the case anymore, and most CCTV cameras have the option of wireless connection instead. A wireless CCTV system has many advantages.
Wireless CCTVs utilize Wi-Fi to connect with the security system in general and don’t require any cables for data. This will greatly simplify 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.
However, wireless CCTV will require power cables and all the traffic must flow and you’ll need a data network that is able to allow for continuous video streaming and an access point that wirelessly connects the data network and the cameras is required.
Conclusions and Recommendations
Modern CCTV systems offer many options that go beyond video recording and monitoring. CCTV cameras come with video analytics functions like ANPR as well as facial recognition as well as object recognition, in addition to different monitoring and storage options 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” or “critical”. Even if they don’t add anything to the cost however, they’re not a freebies: properly implementing these functions can be accompanied by their own set of technical, and sometimes legal issues.
