A surveillance system (10) that can be used covertly or overtly for observing a remote location (A) and providing information about events occurring at that location. Sensors (100-208) are used to obtain real time information about events at the location. The sensors include imaging devices, audio equipment and sensor detecting the presence of explosives or NBC materials. A transmitter (14) converts outputs from the sensors into a secure format and the resultant information is transmitted from the remote location to another location (B) distant from the location under surveillance. At this distant location, the information is converted into a video display format and is displayed, in real time, to one or more users of the system. This enables the users to be able to immediately respond to what is happening, or not happening, at the remote location and to undertake appropriate action in response to the immediate situation at the remote location. |
