Connection damaged.
Exploring this odd behavior, I wonder which cable would need to be removed for the camera to remain active and visible on the network yet remain unreachable. The signs of corrosion and a stuck contact suggest a possible fault, but the device still shows up—raising questions about its connectivity status.

I know the basics of POE, but I've encountered this issue before with multiple cameras. It seems the devices can receive data, yet the connections for sending it aren't working.
It seems the connection problems are clear from the obvious connector issues. Yet, there are times cameras with bricked or damaged firmware, or major failures, where the network IC still functions and maintains an IP address at lower network levels. You can reach them via ping, and scanning tools will detect them. Lights are on, but no one is home. If data transmission issues exist, they should normally be resolved automatically.
I have also had it happen before that a bad connection messed up the camera and it needed to be reset and re setup in order to function again. This one has an elusive reset button but I have time to find that while I wait for a new connector.
The reset mechanism might be located on the cable itself, the original connection could have failed, and the reset button might be positioned there. This setup is common with trendnet cameras, which typically lack a visible reset button on the device. Are there any wire pairs that, when crossed, could indicate a reset?
