My friend bought a cctv system 8 cameras an a DVR 3 years ago , there is no name on the dvr its self but when scanned from an app it comes up with active vision 360
After Updating software it turned off and turned on with a white screen that flicks on and off
I have been on support site there really isnt much i have a also emailed them
Ive attached some image when it was working maybe it might help
Any ideas ?
