Security control system and method of operation
First Claim
1. A security control system comprising:
- a system controller for receiving a plurality of video and alarm signals from a plurality of sources, each said alarm signal being associated with a respective video signal; and
for selectively outputting a subset of the received video signals in response to receipt of said alarm signals, said subset comprised of the video signals corresponding to said alarm signals;
a display controller for receiving said subset of video signals output by said system controller, for processing said subset of video signals into images for display on a display means, for causing said images to be displayed in a predetermined area of said display means corresponding to said alarm signals, and to scale said images depending on the number of such images, such that those images can be displayed simultaneously within said predetermined area of the display means; and
a display means for displaying said plurality of video signals having at least one display device containing the predetermined areas for displaying said images output from said display controller in response to said alarm signals.

Abstract
The present invention provides a security control system, comprising a system controller (2) arranged to receive video signals from a plurality of video sources, and to selectively output a subset of the received video signals for display on a display means, and a display controller (10, 12) arranged to receive the subset of video signals output by the system controller, and to process those signals to generate images for display on the display means. In accordance with the present invention, the system controller (2) is further arranged to receive alarm signals, each alarm signal being associated with a video source, the system controller (2) being responsive to receipt of an alarm signal to output the video signal of the associated video source to the display controller. The display controller (10, 12) is then arranged to cause any images generated from video signals associated with alarm signals to be displayed in a predetermined area (M11) of the display means.
By ensuring that all of the video information associated with alarms is displayed in a predefined area, it is easier for the operator to review that video information in order to ensure that effective action is taken in response to the alarm condition(s).

12. A method of operating a security control system, comprising the steps of:
-
(a) receiving video signals from a plurality of video sources; (b) selectively outputting a subset of the received video signals for display on a display means; (c) processing the signals output at said step (b) to generate images for display on the display means; (d) receiving alarm signals, each alarm signal being associated with a video source; (e) responsive to receipt of an alarm signal, outputting at step (b) the video signal of the associated video source; (f) scaling said images generated at step (c) from video signals associated with alarm signals depending on the number of said images, so that said images are displayed simultaneously in a predetermined area of the display means; and (g) displaying said subset of said images on said display means, said display means comprised of at least one display device containing the predetermined area for displaying said images.
