Good Afternoon, We've recently bought a new retail location that had an ArmorView DVR system. The previous owner had forgotten/lost the password and we would like to use this system. Does anyone happen to have the owners manual or default admin password? It said Default password is NULL but when pressing enter, 6 spaces, or 000000 I still get password incorrect. I have reset it to the default settings, just need some help finding the proper password. Thank you
