Whether CCTV is installed covertly or openly, modern digital communication technology enables SMS to monitor the situation anywhere in the world. Using telemetry, control can be maintained over cameras, lights, gates indeed any building management function.CCTV monitoring falls into two categories, reactive or proactive and both require a different level of service.Reactive CCTV monitoring involves alarm detection on site which initiates a picture transmission to the monitoring centre. Depending on the requirements and the situation the alarm is dispatched to a response agency.Proactive monitoring is real time, for example city centre or high street locations. In this instance the operator is constantly reviewing the location and informing security or the emergency services to dangerous situations.In both types of monitoring there is recorded evidence of what was seen and often this is used to assist the police in their enquiries. Historical evidence is used to supplement non related incidents, enabling the police to build a case.
