CCTV is a situational measure that enables remote surveillance of a locale. This makes it possible for the police and other law and regulatory agencies such as private security to respond to incidents when alerted and to have information about what to look for when they arrive. The storing of images facilitates post-incident analysis that may be helpful to an investigation. There are many different types of CCTV systems and they have different capacities to meet a variety of objectives.CCTV systems can differ quite markedly. Cameras can be:
* Static (focusing on a single view)
* Able to pan, tilt and zoom (moved by operators or placed on ‘tours’ toSurvey a succession of scenes)
* fixed (permanently installed in one location)
* redeployable (moved around power points within an area)
* Mobile (placed in vehicles and transported to where they are needed)
They can transmit analog or digital images via cable or wireless links. The images can be recorded in different ways with different implications for quality. The many methods of storing and manipulating images have different implications for the type and speed of monitoring that can be carried out. The availability of specialized uses such as number plate and facial recognition has generated yet more potential applications of this flexible technology. The technology is only one part of a CCTV system. No system can work without a control room and there is wide variation in the way that these operate.
