One of the main advantages of adopting the IP CCTV approach to system design is the ability to utilise computer networks as the transport medium.
The use of existing infrastructure, for example the corporate computer network, can maximise legacy investment.
However this approach is not without risk as changes in security policy or vulnerabilities caused by regular maintenance activities can disable the network, resulting in a loss of image transmission or even a loss of the corporate network.
These risks can be lessened by careful management and working in close co-operation between the CCTV system and corporate computer network departments.
Transmission of video across a computer network is in most cases create the most intensive network load of any application or service typically seen on the corporate network.
Careful system design is required to mitigate network loading and to plan for the inevitable increase in bandwidth required for CCTV video services, which will be an increasing problem due to future anticipated changes in technology (e.g. the growing use of larger megapixel cameras).

With larger and more complex systems, an essential function of the management system should be the ability to monitor the traffic on the network. Establishing real-time monitoring of the network will highlight network congestion, faulty items attached to the network, confirmation of security policy & SLA compliance and the creation of statistical base for system expansion.

Positive action will to secure the video data carried on the network from both external attack and internal disruption
If Wireless LAN (WLAN) or Wi-Fi systems are incorporated in the computer network, additional security measures needs to be implemented to comply with current standards.
Comfort Zone has a layered series of solutions to securing the computer network which include WLAN Defence and SecureNet.[Read More]
