Abstract
A video security system (10) capable of monitoring and recording fixed and moving targets and recording management information into a video signal such that the text can be removed from the video image produced by the video signal at playback of the recorded video signal. The VSS (10) allows a camera (70b) to switch (toggle) between two or more view positions of interest and to set the view positions into memory by pressing a single switch. The cameras (70b) are controlled to move rapidly, but accurately, between the positions within controlled parameters of speed and acceleration--including a period of substantially zero acceleration between changes in the rate of acceleration.
