Troubleshooting ideas when the explosion-proof camera has no image

When an explosion-proof camera has no image, it should be checked one by one in the order of power supply, wiring, network or video signal, camera movement and display platform.

First confirm whether the voltage and polarity meet the device requirements, then check the wiring, terminals, switch ports, IP address, network connectivity and platform account configuration.

Do not dismantle equipment in hazardous areas while power is on. If on-site troubleshooting cannot be restored, record the indicator lights, network status, and device configuration, and contact technical personnel.
