Abstract

An interface adapter (32, 46, 48, 52, 82, 90) is connectable to a video camera (10) for example in security or surveillance applications. The adapter (32, etc.) conveniently provides interfacing for transmission of video signals generated by the camera, employing any one or more interfaces or transmission media, such as fiber-optic, radio frequency (RF), internet protocol (IP), wireless, twisted-pair (UTP), etc. By using the adapter, a single camera model having one native output transmission connector (14) can be deployed for a variety of applications that may require various other transmission media or connections (34, 36, 50, 92). The adapter makes the camera immediately ready for installation and connection to any desired transmission media without time-consuming wiring of external or standalone transmitters or transceivers. And the adapter preferably conforms to the camera enclosure for a clean, unitary appearance of the combined apparatus (FIG. 3, FIG. 11).

Claims

1. An interface adapter for mounting to a target video camera for transmitting video signals originating in the camera, the camera having a first native connector to output the video signals, and the adapter comprising:

a substantially rigid housing;

a first connector mounted within the housing and arranged so as to establish electrical connection to the native connector to receive the video signals originating in the camera while the adapter is mounted to the camera;

a second connector mounted in the adapter and exposed outside the housing for connection to a transmission medium; and

means in the adapter for coupling the output connector to the first connector to receive the video signals originating in the camera,

wherein the target video camera has a back panel that includes the native connector and the housing is generally shaped so as to cover at least a portion of the back panel that includes the native connector.

2. An interface adapter according to claim 1 wherein the housing includes an aperture for making a power connection to the camera.

3. An interface adapter according to claim 1 wherein the second connector includes at least one of a twisted-pair terminal block, a BNC connector, an RCA connector, a USB connector and a fiber optic connector.

4. An interface adapter according to claim 1 wherein the second connector comprises a wireless transceiver.

5. An interface adapter according to claim 1 wherein:

the adapter includes a circuit board mounted within the housing;

the first connector is mounted to the circuit board at a selected location and aligned for mating engagement with the native connector on the camera to receive the video signals when the adapter is connected to the camera and the camera is in operation.

6. An interface adapter according to claim 5 and wherein the second connector is mounted to the circuit board in the adapter and extends outside of the housing for connection to the said transmission medium;

and the second connector is electrically coupled to the first connector via the circuit board.

7. An interface adapter according to claim 5 and wherein the housing includes a first section configured to overlay at least a portion of the target video camera back panel, and a second section configured to overlay at least a portion of a side of the target camera.

8. An interface adapter according to claim 5 and wherein the first connector comprises a push-in BNC connector.

9. An interface adapter according to claim 8 and wherein the second connector is coupled to the first connector via a transmitter module mounted on the circuit board.

10. An interface adapter according to claim 8 including a terminal block to connect external power for powering video output interface electronics.

11. A method of wiring a target video camera for transmitting video output signals from the target video camera to a remote location, the method comprising:

providing an adapter mechanically compatible with the target video camera in that the adapter includes an input connector arranged for mating engagement with a native connector on the video camera while the adapter is attached to the video camera;

attaching the adapter to the video camera, including engaging the input connector with the native connector;

providing a desired output connector on the adapter, coupled to receive the video output signals from the native connector;

connecting the output connector to a corresponding transmission medium for transmitting the video output signals from the target video camera to the remote location;

wherein the adapter includes a rigid housing, and the housing has a predetermined shape that extends generally parallel to an external surface or back panel of the camera so that the adapter is substantially contiguous to the camera while attached thereto; and

wherein the housing substantially overlies the back panel of the camera.

12. A method according to claim 11 including connecting an external power supply to the adapter, and in the adapter, providing power to the camera and providing video signal-output transmission power, both derived from the external power connection.

13. A method of wiring a target video camera for transmitting video output signals from the target video camera to a remote location, the method comprising:

providing an adapter mechanically compatible with the target video camera in that the adapter includes an input connector arranged for mating engagement with a native connector on the video camera while the adapter is attached to the video camera;

wherein the adapter includes a rigid housing that substantially overlies the back panel of the camera, covering the native connector;

attaching the adapter to the video camera, including engaging the input connector with the native connector;

providing a desired output connector on the adapter, coupled to receive the video output signals from the native connector; and

connecting the output connector to a corresponding transmission medium for transmitting the video output signals from the target video camera to the remote location.

14. A method of wiring a target video camera according to claim 13 wherein said connecting the output connector to a corresponding transmission medium includes providing a wireless transceiver for transmitting the video output signals from the target video camera to a remote location.
