NEED
IP Video surveillance has been with us since the 1970s and we are all now used to the idea and understand the benefits that it brings. In transportation, video cameras help keep traffic moving and highlight potential congestion before it occurs. In retail environments, CCTV reduces shoplifting and improves store operations by identifying queue build-ups at checkouts. In public places the site of a camera makes people feel more secure from crime and helps protect buildings from vandals. In the finance world cameras in banks and ATM machines help provide an audit trail of transactions to prevent fraud and reduce theft.
Advances in digital camera technology mean that many new applications are now feasible. Features such as: motion detection, sound and heat activation, advanced pattern recognition and low light operation, all allow new intelligent applications to be developed. What’s more, with the use of industry standard components and advanced digital circuitry, the price of the components is falling drastically making a video surveillance application feasible for smaller companies or even for domestic applications in the home.
Video Surveillance equipment has traditionally been supplied by security and video component manufacturers who specialise in this market. These solutions have tended to be custom-built resulting in a high price tag. The market is now moving from a mixed analogue/ digital basis to a fully digital solution using industry standard components such as: IP cameras for video capture; Ethernet and Wi-Fi for video transmission; PCs for control and monitoring; standard computer hard disk drives for storage and archiving.
This technology shift means that sophisticated IP video surveillance solutions are now becoming affordable for even the smallest companies or private users. With their industry standard components, they can be installed and integrated with the existing network infrastructure using wired or wireless Ethernet connections. Monitoring the cameras no longer requires expensive video recording and viewing suites; camera output can be stored on standard disk arrays and viewed on standard PC monitors either locally or remotely wherever there is a good network connection.
