ABSTRACT:
A video security surveillance system comprises a backup video switching control unit connected in tandem with a primary video switching control unit. A backup controller monitors operation of the primary switching control unit and automatically effects transfer of control of the video security system to the backup switching control unit upon detection of a failure condition of the primary switching control unit. During normal operation, the backup switching control unit is continuously updated with the same configuration parameters as the primary switching control unit so that in the event of a failure condition requiring a transfer to the backup switching control unit, the transfer of control is effected wherein the backup switching control unit operates in accordance with the same configuration data as the primary switching control unit prior to the failure condition.
