Abstract

A closed circuit television (CCTV) observation system accommodates a video feed from one or more wireless camera/transmitters to a single monitor, which also provides inputs for wired cameras. In the preferred embodiment wireless receivers are implemented into a multi-channel monitor, so that either wired or wireless cameras may be used, depending upon the user'"'"'s surveillance requirements and the availability of cable pathways at the installation location. To reduce interference the wireless receiver is disposed on the back cover of the monitor offset from the electron beam generator of the monitor and generally parallel to an optical axis of the electron beam. A video surveillance system according to the invention may incorporate different combinations of wired cameras and wireless cameras, and may sequence through real-time video images generated by the various wireless cameras while providing a display of multiple camera segments, so that by a combination of screen splitting and camera sequencing a single monitor can be used to efficiently monitor cameras in many different positions, in real-time. The monitor may be equipped with a video capture card, which outputs the video image displayed on the monitor to a processing appliance such as a personal computer or computer network via a computer-compatible interface.

Claims

1. A closed circuit television observation system, comprising

at least one wired video camera and at least one wireless video camera,

at least one monitor having a plurality of channels, and at least one video port coupled to at least one channel for connection to the wired video camera, and

a wireless receiver having at least one channel for receiving a video signal from the wireless video camera.

2. The closed circuit television observation system of

claim 1

in which the wireless receiver has a plurality of channels for receiving video signals from a plurality of wireless cameras, comprising a sequencer for sequencing between images generated by the plurality of wireless cameras.

3. The closed circuit television observation system of

claim 2

in which the sequencer is integrated into the wireless receiver.

4. The closed circuit television observation system of

claim 2

in which the monitor comprises a quad splitter for dividing the monitor display into four segments, each segment displaying a video image corresponding to a different video camera.

5. The closed circuit television observation system of

claim 4

in which one of the segments displays a video image corresponding to a wireless camera, comprising switching a sequencer for sequentially switching the wireless receiver between images generated by the wireless cameras.

6. The closed circuit television observation system of

claim 4

in which the monitor comprises circuitry for outputting the video image displayed on the monitor to a processing appliance.

7. The closed circuit television observation system of

claim 6

in which the processing appliance is remote from the observation system.

8. The closed circuit television observation system of

claim 7

in which the processing appliance is part of a computer network.

9. The closed circuit television observation system of

claim 8

in which the observation system communicates with the computer network over a telephone line.

10. The closed circuit television observation system of

claim 9

in which the system is programmed to detect motion within one or more of the video images or a selected portion thereof, and in response to detected motion, to initiate a dial-up procedure to contact a person or connect the video output to a monitor at a remote location.

11. The closed circuit television observation system of

claim 9

in which the circuitry for outputting the video image is remotely addressable by an IP address.

12. The closed circuit television observation system of

claim 11

in which the circuitry for outputting the video image is associated with video streaming software.

13. The closed circuit television observation system of

claim 1

in which the wireless receiver is disposed on a circuit board mounted on a back cover of the monitor offset from an electron beam generator of the monitor and generally parallel to an optical axis of the electron beam generator.
