Reset DVR password to Factory default

Recommended Posts

I lost the admin password of my 4 CH DVR.

The DVR is not well identified, it reports the China brand HENGSTAR, I have not found a support web site on internet.

The main board has the following code: HI3520D_V1_65.

I have already tried all common things as common passwords (000000, 123456, etc.), removing the battery, etc.

Any suggestions to help me?

 

I attach a set of photo of the DVR (front, back and main-board).

WHY DID YOU NEED TO SET A PASSWORD IN THE FIRST PLACE?

 

WAS IT FOR SECURITY REASONS?

 

Now you want to discuss getting past it in a PUBLIC forum, is that also for security reasons?

Without the admin password I can not change the setting of the DVR, also when I press the REC button and other buttons the DVR ask me for a password.

The reset methods are not a security risk...they are widely known algorithms that require you to be present in front of the NVR and cannot be applied remotely...

I do not need to reset the password remotly, I completly disinstalled the DVR and the camera. I would like to reuse the DVR in other installation scenario. But... I lost the password.

We English have a strange sense-of-humour many other nationalities cannot understand, don't be worried or concerned about it.

Ah ok!

I Will study to learn english man humor (I think its too hard for an italian.)

Humor apart, no one can help me to recover/reset password (the pc motherboards have a simple jumper to reset the BIOS paasword, a similar procedure could be enough).
