I have two Hikvision cameras DS-2CD2042WD-I
Both cameras are inoperative.
When connected to a switch or computer, the link does not go up.


I tested the wiring until the board is whole.
I supply power with a separate 12 volt unit.
Resetting to factory settings does not help.
On the board where the power comes and the network is constantly lit red LED.

Because of what it happened is unknown, I got such cameras ...

Tell me, this may be due to firmware? Or is it hardware problems?

Probably not.

Probably yes.
often a corroded RJ45 connector on the camera ethernet cable.
But you have tested the connections straight to the connector inside the camera?
Have you examined the camera RJ45 connector with a magnifying glass to check for any discolouration or signs of corrosion?

Yes, I checked. Everything is clean, the wiring is working. I took apart the camera and checked the diode tester.
 
Yes. Thanks!
I did not have a USB-UART converter with a level of 3.3v ...
I tried using Arduino as converter but apparently due to the fact that there levels 5v did not work ... Nothing is visible ...

Tomorrow I will try to find a normal converter and connect ...
 
I tried this, see attachment

USB - COM TTL (RS232) CH340
Another device (router) I see through it perfectly.
