IP-based surveillance systems will show a lot of growth in the IT and security industries because they offer a scalable, company-owned solution that offers the advantages of flexibility and low cost of ownership. A digital system can be built within an already existing IP network, and this fact will make a company's budget department breathe easier.

The use of CCTV surveillance systems has steadily increased for detection and crime prevention. Modern technology has led to numerous, sophisticated advances in CCTV surveillance system hardware and software components.CCTV surveillance systems used for monitoring positions in and around rail stations can be quite numerous, depending on the size of the station. The strategic points where CCTV surveillance system cameras may be located are decided by both the purpose of the CCTV surveillance system and by budget.All CCTV surveillance systems might be running at a faster rate, but after closing, they run at a slower rate. The digital user has much flexibility. For instance, users can select a different record rate for each CCTV surveillance system camera as well as set each camera to record in time-lapse mode, event mode or both.

The area showing most promise for the future development of CCTV surveillance systems is IP. It is generally accepted by the industry that IP and Ethernet local area network (LAN)-base installations, with their inherent advantages of scalability, flexibility, functionality and low cost of ownership are rapidly becoming the CCTV surveillance systems of choice. In many cases use can be made of an existing LAN/IP infrastructure inside a building, or even the wide area network (WAN) for longer distance reach.

CCTV surveillance systems are video content analysis (VCA) that uses real-time and recorded images and compares them with a database. CCTV surveillance systems cameras are being loaded with intelligent software, to make them more than passive viewing vessels. Camera surveillance systems recordings can serve as evidence.
