CCTV Systems

摘要

With ever-rising levels of crime and antisocial behaviour and increasing threats of terrorism, the security of buildings is essential in their protection and continued operation. A key element of a security strategy for the protection of non-domestic premises is the use of closed circuit TV systems (CCTV). Systems to date have traditionally been based on analogue devices and transmission, with cameras connected via co-axial cable. However, the latest systems, referred to as IP CCTV, use digital technology communicating over some form of internet protocol network.
