Dahua forgotten admin password - want to do a factory reset - help please.

Did you gain access to the printed circuit boards inside, or merely looking from the outside?
Okay, your pictures appeared just as I was posting my question. Chances are, shorting together two contacts may do the trick. Let me look at your pictures more closely. If I were to guess, I'd check the two contact holes numbered 1 and 2 in your first picture. Use a meter and measure each contact hole to ground. If there are no voltages present, you might try shorting contact hole 1 to contact hole 2 while applying power to the camera. Good luck!!

A second option would be to connect a USB-to-serial cable to the four contact holes beside contact hole 2. You may get a root shell by default when the camera boots up. Then the Linux passwd command would allow you to reset things.

Is there any way to reset dahua camera passwprd without opening the camera?
I mean is it possible to reset the password by software?
 
Hi there - you guys have better eyesight then me for sure as the pin holes are tiny. Is it just the case of putting a bit of wire between pin hole 1 and 2 to short out? Thanks in advance
 
if it doesn't have a switch, it's generally 2 circular vias that are close together.

For best results unplug then connect the reset pins for about 30 seconds starting when you re-apply power.

With power disconnected, connect a wire between vias 1 and 2 circled in red below. While wire is connected between 1 and 2, apply power. Keep the wire connected for a minimum of 30 seconds. It often takes a while to reset and reload the factory firmware. Good luck!
