Abstract

A video security system (10) monitors a premises (F) to detect unwanted intrusions onto the premises. A site control unit (12) obtains and evaluates the images to determine if an intrusion has occurred, and provides an indication if an intrusion is detected. A central station (CS) includes a plurality of workstations (106), and a central alarm computer (104). The computer is responsive to an alarm indication to cause video images, and audio, to be transmitted to the central station for presentation at one of the workstations selected by the computer. Additionally, the computer supplies site specific data to the workstation for display with the video images. Control signals from the workstation back to the site are routed through the computer.

Claims

1. A security system for selectively transmitting video images of an equal priority from a plurality of monitored premises to one of a plurality of displays at a central location comprising:

a site control unit located at each of the plurality of premises capable of transmission of video images from the premises to the central station via a communications link; and

a video server for transmitting the images of an equal priority located at the central station that receives the transmitted images and is adapted to;

continuously monitor all displays to determine whether any of the displays is not currently displaying video images;

transmit the video images, all images having an equal priority, to the first display encountered that is not already receiving video images from the video server; and

prevent transmission of a video image to any of the displays in the event all of the displays are already receiving video images from the video server.

2. The security system of claim 1 further comprising a data storage adapted for storing relevant site data about the premises from which video images are being transmitted for presentation at the selected display together with the video images.

3. The security system of claim 1 wherein the site control unit further processes and transmits an audio signal detected from the premises together with the video image.

4. The security system of claim 1 wherein said storage means is a mass memory.
