Issue: Rear analog camera has a blue screen
Cause: Configuration and wiring do not match, camera is not getting 12 volts, the A/V connection is loose, or a broken physical component
Physical components that can cause this issue:
- Spider cable
- Power cable
- Molex connector
- DVR
- Camera
Troubleshooting:
Verify Configuration
- Under Unit Configuration, click on Devices
- Find the video device for your rear camera - usually named Back Seat, but this can be different per department
- In the example above, I have named my camera Analog
- The device should be configured with Video FC(number)
- The number next to Video FC(number) tells you which physical cable you need to be connected to on the spider cable. The spider cable is labeled.
- In the configuration above, you see that it is Video FC1 so in the picture below, I am connected to Video 1 and Audio 1
- If the physical connections do not match the configuration, please correct
Reseat AV Cable
- If the AV cables were connected correctly, please reseat both cables to verify that connection is good
- There is a small chance that the audio and video cables got flip flopped when installed with an extension cable
- Swap the audio and video cables around
- If issue is not resolved, swap them back to how they were originally
- Swap the audio and video cables around
- If issue is still present, reseat the cable connected to the DVR
Verify Power
- The most common cause of this problem is that the power cables were either installed incorrectly or became dislodged
- The power cable has two cables that connects to the dvr through a molex connector on one end and barrel cable on the other
- Power – Black cable (New cables will have a white sheath at the end of the cable)
- Ground – Black cable with a faint white stripe
Old Power Cable
New Cable
- Ground should be plugged into A1 and power should be plugged into A2
- Measure power output with a multimeter
- Disconnect the power cable from the camera
- Place the positive lead in the cable and have the negative lead on the outside of the cable
- You should have 1 of 3 results
- You should get 12v if it is wired correctly
- If you are getting -12v, the cables need to be reversed on the dvr
- If you are not getting any voltage
- Remove the cables from the molex connector
- Measure A2 on the molex connector
- If there is 12v, reinstall cable and test again
- Replace power cable if no voltage
- If there is no voltage, remove connector and measure directly from the dvr at A2
- If there is 12v, reinstall the connector and test for voltage
- If there still is no voltage, replace molex connector
- If there is no voltage, replace dvr
- If there is 12v, reinstall the connector and test for voltage
- If there is 12v, reinstall cable and test again
Verify Components
- If you completed the above troubleshooting and the issue still remains, then the cause of the problem will either be the camera, spider cable or dvr
- Depending on what is easier for you, swap either the spider cable or camera with a known good component from another vehicle/bench stock
- If neither the cable or camera fixes the issue, please let support know and we will replace the dvr
