Issue Summary
The camera does not work due to a POE power supply failure.
Due to current peak when connecting the NVR and adapter DC Jack, the 52V Wire Bond inside POE (PSE) IC is disconnected.
Resolution
To prevent current overload:
- Connect the adapter DC Jack to the system.
- Connect the adapter AC 220~100V.
NOTE: There is a peak value of current, but it is
at a minimal level (10mA or less).
