mito 0 Posted February 13, 2017 Hello, I have a little (BIG) problem. We moved to a new little office with cameras system and dvr "ready to use", but no password. I searched over the net but nothing helped. The model Pravis AVS-1611 (4 cameras channel). I took out the battery without success. After taking out the battery the hour system change to 01/01/2007 I read that the default password is BLANK i mean no password. i attached a picture. thanks in advance for the help.
