Video systems keep perimeter protection in the picture
Cameras are the eyes of modern security systems, making them an indispensable part of site protection. The advantages of video technology can really come to the fore whenever large areas, or several locations, need to be monitored centrally.
Video systems are ideal for producing recordings in the context of access control, burglary protection or motion detection measures. These recordings can then be used to determine further action necessary. Ideally, they are tailored individually to the respective application and the properties to be protected. Often, however, cameras will pay for themselves thanks to their deterrent effect. If mounted in a visible location, they can prevent unauthorised access or criminal acts.
Depending on requirements, the cameras available range from models that provide video images only to high-tech solutions complete with sophisticated analysis tools. The devices themselves can offer smart features and provide information for perimeter protection from their sensors. If you only need motion detection, stripped-down video systems or smart video cameras, which are only triggered in the event of an alarm, i.e., if movement is detected, may be sufficient.
Video surveillance as part of the IoT
If more effective solutions are required, it is recommended to connect video systems with the security IT and other perimeter protection components. These are connected with servers via the Internet of Things and combine the electronic processing in the camera with other software applications. If, for example, the system reports the use of a card at an entrance, the camera is triggered and the image recognition software can identify the vehicle registration. In this context, the integration process is simplified by software and interface standards and norms like DIN EN 62676 “Video Surveillance Systems for Use in Security Applications”.
However, the use of cameras for security purposes can do much more than just identify unauthorised persons or vehicles on a site. Equipped with thermal imaging sensors, they are not only capable of detecting people in all light conditions but can also capture fires and smoke development at an early stage.
Video codecs and digital recording devices offer more extensive possibilities thanks to their computing and storage capacities. These options include artificial intelligence, for example. In this context, algorithms make it possible to use predetermined data or past insights, better identify events, and avert dangers.
Only a secure video system improves security
Nevertheless, the use of video technology on company premises does have its pitfalls. Data privacy and data security absolutely need to be considered in the planning from the very beginning, to ensure legally compliant use of the technology. As far as data privacy is concerned, it is often sufficient to provide signage indicating that an area is monitored. Other factors to consider are any internal agreements between the company and employee representatives, and the need to protect the privacy of employees or visitors, e.g., in changing rooms.
As with all networked systems, it is also important when using video equipment not to make the security system a gateway for attackers. Criminals can exploit video images, sound recordings or movement patterns. For this reason alone, it is advisable to incorporate the video surveillance system into your IT security infrastructure.
Planning video security systems
When planning video systems, the key factor is the necessary image quality. Aspects like contrast, resolution, images per second and resistance to weather conditions all need to be reconciled. If, in a worst-case scenario, images are unusable or not satisfactorily analysed by the software, companies are saving money in the wrong place. A video system that is too powerful, on the other hand, could at worst cause investment costs to skyrocket. The investment decision should therefore always be based on the costs involved and the required image quality. When it comes to planning, experienced consultants provide valuable services. And such experts in video surveillance can be found at Perimeter Protection in Nuremberg, for example.
Even after a system has been installed, it is necessary to continue to maintain the hardware and constantly keep the software upgraded. This is the only way to keep the system functioning and ensure cyber security. Lack of maintenance can lead to frequent false alarms, for example, and therefore jeopardises acceptance of the system and casts doubt on its purpose. This is why it is important to carefully instruct and train security personnel, define responsibilities, and produce testing and maintenance schedules. If the resources are not available in your own company, you can engage qualified security providers to ensure that your equipment constantly complies with the state-of-the-art.
When investing in a video surveillance system, companies therefore need to take a range of factors into account that will vary from property to property. Once the right application has been chosen, this often results in further benefits for the security of people and assets.
