types of
surveillance cameras like outdoor surveillance cameras that are kept in the streets which are used to track traffic violators and other anti social activities. Domestic cameras which are positioned inside the homes but facing towards the periphery to keep a watch on home intruders and thieves. There are also few nest cameras which can be kept within the home or store to monitor activities of workers or nannies. In the market we can find many more such cameras which are specific to purpose.

These work on the basic principle of infrared, that is when a door or a window is opened and the infrared sensor is cut without prior intimation to the system, the security alarm goes off and alerts the concerned party of an abnormality in situation.
