The Informatin technology has become very capable to complite the advanced business needs. In the course internet, email, fax etc. plays significant role to comunicate with each other. The same way security become hi-tech and get aquented with latest technology and advancements. The Video surviellance has been a very popular tool for the security. We usually found ourself being wached at store, bank, restaurants etc. The normal CCTV cameras and its tipical installation can easly fulfill this need but in advancment where we wish to monitor the distant location or the location apart from us we have to choose another latest way of video surviellance which is being adopted by us.

Industrial processes
Industrial processes which take place under conditions dangerous for humans are today often supervised by CCTV. These are mainly processes in the chemical industry, the interior of reactors or facilities for manufacture of nuclear fuel. Use of thermographic cameras allow operators to measure the temperature of the processes.

Monitoring for safety
A CCTV system may be installed where an operator of a machine cannot directly observe people who may be injured by unexpected machine operation. For example, on a subway train, CCTV cameras may allow the operator to confirm that people are clear of doors before closing them and starting the train. Operators of an amusement park ride may use a CCTV system to observe that people are not endangered by starting the ride. A CCTV camera and dashboard monitor can make reversing a vehicle safer, if it allows the driver to observe objects or people not otherwise visible.

Closed Circuit Digital Photography (CCDP)
A surviellance image captured using a megapixel CCDP camera.A development in the world of CCTV (October 2005) is in the use of megapixel digital still cameras that can take 1600 x 1200 pixel resolution images of the camera scene either on a time lapse or motion detection basis. Images taken with a digital still camera have higher resolution than those taken with a typical video camera.Relatively low-cost digital still cameras can be used for CCTV purposes, using CCDP software that controls the camera from the PC. Images of the camera scene are transferred automatically to a computer every few seconds. Images may be monitored remotely if the computer is connected to a network. Closed Circuit Digital Photography (CCDP) is more suited for capturing and saving recorded photographs, whereas Closed Circuit Television (CCTV) is more suitable for live monitoring purposes.
