Help Resetting a pentabrid xvr501h-16-s2 remove admin password

[DarrenA 1]

I bought this system used from a fellow on Facebook rummage, and when I got it there was a "pre-existing" password set for the admin account. We can not seem to figure out what it is, so the unit if effectively locked.

Is there a way to re-initialize the system?

I have tried pulling the onboard battery for about 2 hrs, pulling the HHD deleting all partitions ect... (Per his advice) Still will not let me reset a password.

I am stuck and need help.

Hi. Without knowing your units serial number you have a few choices 

switch off unit for 20 minutes then try each of these passwords

082752
028608
179968

as far as hard drive… there is no partitions 

I would leave it out of your recorder until you have setup a new password …. Then add the hard drive then go into system setup and format the drive from there

Thank you very much I will attempt these later today when I get home.

OK I tried those and no luck. Serial Number on bottom of the unit is 3K07644PAZB56B6

I hope this helps

Hi please try this one

[DarrenA 1]

I just tried that one also. Still nothing. Just to make sure I am doing this correct. As soon as I get it up and running I try and enter main menu I am asked for the admin password, and in there is where I am trying these. Or is there some place else I am supposed to do these from?

Again thank you for trying to assist me.

LOL none of those worked, I am sorry this is being such a pain.

Well I contacted savvytech, they told me this unit was sold by another company, but was given there email address. So I reached out to them but as of yet no reply. Why in gods green earth does a damn NVR need frikking impossible security. I mean a danm reset button inside the unit would be nice. press it and Boom factory reset. No need for this crazy security.

Hi. Your system is made by dahua …. And they do change there reset method often 

I will pm you another method that might help

[DarrenA 1]

I could KISS you man. (no gay) OMG you saved my butt. Yes I know about the reset button but did not know HOW to use it. and even pressing it really did nothing. I thank you SO much. I was literally loosing my mind on this, and the seller was worried I was going to ask for my money back. I am so happy to have my system running again, I cant thank you enough.

OK one last Question and I think I am done. What iOS software can I use with this DVR so I can access it on my Phone? I have looked at a couple but I am not sure...... Also the QR code on the Device when I scan with my Phone tells me that, that Software /App is not available in my region.....  Not that I really NEED it but it would complete the system for ease of access.
