Abstract
A video security system (10) monitors a premise (F) to detect unwanted intrusions onto the premises.

Only if the source is determined be one of a predetermined class of causes, is an indication provided to an alarm unit (16). The alarm unit, which is also connected to a plurality of conventional sensors (S1-S3) is responsive to the indication to cause the processor to transmit authenticated video images of the scene in which the motion is detected to a central station (CS). There, a video server (102), in conjunction with an alarm computer (104), enables the images to be displayed at a selected workstation (106) for viewing by an operator (O).
