I don’t know that specific model but usually if you take it apart there is a “button” inside is not very obvious where it is, but you hold the button down and apply 12 VDC / PoE power, then release the button after about 30 seconds.

also the cliff notes in the wiki at the top of the page (blue bar) has some details for resetting other Dahua cameras

I opened it, but there are no buttons. I assume you should short-circuit something

 

[giomania]

Correct

When there are no buttons you have to short-circuit to solder points on the circuitboard when they don’t have a button installed

the problem is that I do not know how to intervene

I’m afraid we have exceeded my knowledge base so will have to wait for someone more experienced to chime in.

I suggest you post a picture of the circuitboard.
