Deploying IP cameras necessitates not only an indoctrination of networking concepts, but also a firm grasp of analog video and how to translate those design principles into the language of digital surveillance. Sizing up an application calls for equal consideration of a range of factors, such as purpose, location, light, bandwidth and image size.

Networked video surveillance systems are at the forefront of the convergence of IT and physical security. However, no matter what the delivery method, the proven, time-tested principles of CCTV system design remain vital. Applying these theories to IP-based systems can help overcome some inherent shortcomings.

As networked video becomes more prevalent, security contractors are faced with either learning the technology or greatly limiting their relevance. To a large extent, however, it is a case of fearing the unknown. Aside from some new terminology and basic concepts, the fundamentals of troubleshooting network-based systems are similar to those of traditional surveillance systems.

When electronic security systems fail or malfunction, more often than not it’s something small and relatively basic that lies at the root of the problem. Proper termination for a video surveillance system is a prime example. Understanding the different types of termination and how to test for them are the stepping-stones to ensuring systems stability.

When designing CCTV systems, determining the number, type and location of cameras and DVRs is often only half the battle. Security technicians also need to know what it takes to get video to the network as well as onto it. This means understanding the devices and technologies necessary to effectively interface with your client's IT manager.
