All Indicator Lights Off

Symptom

After the camera was connected to power, none of the four indicator lights on the camera were lit.

Possible Causes

  • The camera cables are not connected correctly.

  • The voltage of the power supply is abnormal.

  • The DIN rail power supply is not grounded.

Solution

Please follow these steps to troubleshoot the issue:

  1. Refer to Camera Hardware User Manual and check if the camera cables are correctly connected and the connector nuts are fully tightened.

    • If the camera cables are not correctly connected, please correct the connection and check the indicator lights on the camera again.

      • If the indicator lights on the camera indicate proper working condition, the troubleshooting is completed.

      • If the indicator lights still indicate the presence of issues, proceed to step 2.

    • If the camera cables are correctly connected, proceed to step 2.

  2. Disconnect the camera DC power cable from the camera, and use a multimeter to check the voltage of the M-12 A connector and see if it reaches 24 V.

    • If the voltage does not reach 24 V, check aspects such as the connection of other cables in the power supply line and make corresponding corrections. Then, connect the DC power cable to the camera again and check the indicator lights on the camera.

      • If the indicator lights on the camera indicate proper working condition, the troubleshooting is completed.

      • If the indicator lights still indicate the presence of issues, proceed to step 3.

    • If the voltage reaches 24 V, proceed to step 3.

  3. Check if the power supply is correctly grounded: if a DIN rail power supply is used to supply power to the camera, refer to Camera Hardware User Manual to check if the PE wire of the DIN rail power supply is correctly connected. If a power adaptor is used to supply power to the camera, check if the power outlet to which the 3-prong connector of the adaptor AC power cable is connected is correctly grounded.

    • If the power supply is not correctly grounded, the camera might have been damaged. Please contact Technical Support.

    • If the power supply is correctly grounded but the symptom is still present, please contact Technical Support.
