Abstract

A large number of remote areas are automatically monitored with a binarily related smaller number of normally blank video display screens at a monitoring station. When a disturbance is detected in any monitored area, the associated screen goes active to display the area to a security officer at the monitoring station and concurrently, if desired, superimpose on the image or print on hard copy the time and date and address of the area, activate a video tape recorder, and activate a two-way communication system with the area.

Automated Video Monitoring System

A large number of remote areas are automatically monitored with a binarily related smaller number of normally blank video display screens at a monitoring station. When a disturbance is detected in any monitored area, the associated screen goes active to display the area to a security officer at the monitoring station and concurrently, if desired, superimpose on the image or print on hard copy the time and date and address of the area, activate a video tape recorder, and activate a two-way communication system with the area.

The system is shown as comprising a plurality (e.g., four) monitor units 1, each comprising a closed circuit TV camera 2, a field disturbance sensor 3, and an intercom speaker 4. Each camera 2 preferably operates continuously with the video output being applied to a respective modulator/carrier generator, not shown, that provides a modulated signal on an assigned frequency in the VHF/UHF range. For simplicity, each such generator is shown as individually connected by a respective cable 5 to a control device 6 via a corresponding demodulator, not shown; however, if preferred, the various generators and demodulators may be respectively coupled to and decoupled from a common coaxial cable.

Each sensor 3 may be an RF type, 1R type, or a magnetic reed switch. When a disturbance is sensed in a particular area being monitored, a contact, not shown, will close to provide a signal via a conventional telephone line 7 to activate control device 6. Each speaker 4 is wired to control device 6 via a conventional telephone line 8 and is automatically activated by closure of the sensor contact, to provide two-way communication between a security officer at the monitoring sta...
