CCTV security is a handy piece of equipment as it keeps a close eye on the goings on in a particular area. People use it for all kinds of reasons, householders like to be able to keep an eye on their property or family when they are away from home, and businesses use them to secure against intruders or trespassers, as well as checking what their employees are up to when the boss is away. Just the presence of security cameras on the premises can be enough to deter prowlers and prevent misbehaviour.

Installing and operating CCTV is very straight-forward and is great for situations where close surveillance is judged to be necessary.

Security cameras are in use all over the place in a variety of locations, there is probably one in the vicinity right now but you just haven't noticed it. They are used in businesses to watch over the premises either during office hours, or at night when there is no-one around, and are particularly useful when there is a need to identify an intruder or collect evidence for some illegal activity. In the city, it can help maintain peace and order by keeping a watchful eye over a busy high street or public facility by acting as a deterrent against stealing or other kinds of crime. The recorded images can be used as evidence in court cases or for the police to catch criminals and vandals.

The newer models generally facilitate DVRs, digital video recorders, which can be used with any TV or security monitor and incorporate a multitude of features, from built-in advanced motion detection, on-screen display with RTL (real time clock), and multiplexers and quad processors, to channel labels, alarm input and video loss alert. The main advantages of a dvr camera is the amount of video that can be recorded, the more expensive models can record for as long as 720 hours if using a 120GB HDD of high quality video.

Their signal can also be programmed to be sent to the local police station or other designated security firm who will then assess the situation and either send out an alert call or dispatch someone to investigate.
