I have just been given one of these "Bunkerhill" DVR / Camera systems and have had the same gray screen problem have'nt completly figured it out yet.
Apparantly it will work just fine with Windows XP running IE8
I have not been able to get it to work in Windows 7 running IE9
I have not tried Windows 8 yet. One hurdle at a time.
I have tried all compatability modes and reduced security to no effect.
Tried the fixes peviously mentioned no luck either.
I haven't figured out the "Tab repair" mentioned earlier.
Hope this helps a little.
let me know if anyone finds out more
