Hi there and welcome
What you will need to do is reset the unit to reset the password.
To do this, please do the following
Using the remote control, please press the dvr button, then rapidly press
Once entered at an average pace the dvr will ask you if you want to load the factory settings.
Select ok and all factory settings will be loaded. This will not delete any recorded footage
If you do not have a DVR button on the remote. press the return button (the arrow circling back on itself) a few times then Freeze>Alarm>Freeze>Alarm>Freeze> Return
If it does not initially work, try a few times as you need to get the timing correct
The default then is admin as the username and password *****
If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
