Abstract
A camera system includes a digital recording unit. The camera system further includes a camera adapter having a first cable having a connector that connects to a digital connection port of the digital recording unit, and a second cable that connects to a camera port of an analog camera. The camera adapter may include first and second processors that are configured to convert analog audio and/or video signals from the analog camera into digital audio and/or video signals and transmit the digital signals to the digital recording unit through the first cable. The camera adapter may be configured to supply power from the digital connection port of the digital recording unit to the camera port of the analog camera.
Claims20
A camera system for vehicles comprising:
- a digital recording unit including a support structure and first and second cameras mounted to the support structure, wherein the support structure of the digital recording unit is configured to be mounted in a vehicle interior adjacent to a windshield of a vehicle whereby the first camera faces forward towards the windshield, and the second camera faces rearwardly away from the windshield, whereby the first and second cameras are configured to form videos that are stored in digital format by the digital recording unit, the digital recording unit including a digital connection port that is configured to send and receive digital signals and supply 12 volt DC power;
- a third camera that is configured to output an analog signal from a camera port of the third camera, wherein the camera port of the third camera is configured to receive 12 volt DC power to power the third camera;
- an analog camera adapter having:
- 1) a housing, 2) a first cable having a first end connected to the housing, and a second end having a digital connector that is configured to be operably connected to the digital connection port of the digital recording unit, and 3) a second cable having a first end connected to the housing and a second end having an analog connector that is configured to be operably connected to the camera port of the third camera, the analog camera adapter comprising:
- first and second processors disposed in the housing wherein the first and second processors are operably interconnected, and wherein the second processor is configured to convert analog video signals from the third camera into digital video signals and transmit the digital video signals to the first processor, and wherein the first processor is configured to convert analog audio signals from the third camera into digital audio signals and to transmit the digital audio and digital video signals to the digital recording unit through the first cable;
- and wherein:
- the analog camera adapter is configured to:
- 1) supply 12 volt DC power from the digital connection port of the digital recording unit to the camera port of the third camera utilizing first and second conductive power lines of the first and second cables, and 2) communicate with the digital recording unit utilizing first and second conductive communication lines of the first cable.
An analog to digital camera adapter for connecting an analog camera to a digital recorder, the analog to digital camera adapter comprising:
- a housing;
- analog to digital convertor electronics disposed in the housing;
- a first line including a digital connector that is adapted to operably couple the first line to a digital recording unit that is remote from the high definition analog camera, and wherein the first line is adapted to be operably connected to a digital output of the digital convertor electronics to provide two-way digital communication between the analog to digital convertor electronics and a digital recorder;
- a second line including a connector that is adapted to operably couple the flexible analog line to a high definition analog camera, and wherein the second line is operably connected to an analog input of the digital convertor electronics;
- conductive power lines that are configured to supply the connector of the second line with 12 volt DC power that is received from a digital recorder by the digital connector.
A method of providing a digital recording unit with digital signals from an analog camera, the method comprising:
- mounting a digital recording unit in an interior of a motor vehicle;
- mounting an analog camera to the motor vehicle in a location that is remote from the digital recording unit;
- interconnecting the analog camera to the digital recording unit utilizing an analog camera adapter having analog to digital electronics, wherein the analog to digital electronics are operably connected to first and second cables;
- wherein interconnecting the analog camera to the digital recording unit includes interconnecting the first cable to a digital connection port of the digital recording unit, and interconnecting the second cable to the analog camera whereby analog signals from the analog camera are converted to digital signals by the analog to digital electronics and transmitted to the digital recording unit by the first cable;
- and:
- providing 12 volt DC power from the digital recording unit to the analog camera utilizing the first and second cables.
