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).

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).

Your dog? I asked for something that I could not ask? Pease be more clear. Thanks

Sorry, I don't understand (my english is not very well).

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.

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.
