Using corporate network infrastructure for security applications such as video surveillance reveals some problems. It is possible to build separate networks, using specialized equipment and technologies specially developed for security systems, is a better solution.
In today's business world, corporate IT networks are expanding not only to meet needs, but also to include an increasing number of users, applications and devices. As companies use information technology to collect data from all corners of their business, it was proposed to designate with the term "LAN growth", this trend is increasing the load on the corporate network. One of the issues that arises with the expansion of local area networks (LANs) is how to manage the network infrastructure, especially with regard to allowing a large number of users to access data.
Given the industry’s transition to Internet Protocol (IP) -based security systems, problems may arise when streaming video over the local network of an enterprise, as ip-cameras generate a lot of traffic and can overload local networks. How can growing networks meet the demands of more users and applications for the system to work efficiently? This problem is becoming increasingly relevant for video surveillance systems and security in general, many companies come to the conclusion that the best approach is to build a separate IT infrastructure designed specifically for video surveillance and other security systems.
Since the amount of information entering the network for recording and viewing live video is very large, for video surveillance systems it will be relevant to build a separate network infrastructure and, if possible, it should be excluded from the work of the enterprise’s common network as much as possible. For this approach, it is also possible to use innovative solutions designed specifically for the security market.
The benefits of a separate network infrastructure for digital video surveillance
The transmission of video data in a particular network should not compete with other devices that transmit information to the network. Separation of the video surveillance system into a separate specially built network for this purpose allows the system not to pinch video quality, including the use of technologies that provide maximum functionality and reliability.
To maximize the performance of video networks, special devices are used to monitor the effectiveness of the network. These devices take into account factors such as power, environmental conditions, and throughput. Network technologies designed to ensure the security / construction of video surveillance systems also contribute to the integration of a number of safety-related devices and systems (alarm, perimeter security, ACS, POS, LPR, etc.)
The unique needs of digital security systems
Digital security systems, including ip-video surveillance, are crucial for the safety of work and the overall well-being of the company. Safety at the enterprise requires fault-tolerant systems that operate reliably for a long period of time, and are also ready to respond if necessary. The security system must be scalable, flexible and able to adapt to the changing needs of the company, and must not compete for network resources with a growing number of other applications, devices and users in the enterprise network.
The generation of traffic by IP-CCTV systems is too large to use an already overloaded corporate network for it. The security industry has its own unique needs. Not all solutions proposed for network infrastructure are suitable for IP video surveillance. This is a specific equipment that can offer its own unique solutions, but in turn it may have its own special needs.
