Got the replacement 550 Last week . This camera IR works like it is supposed to . The last the IR would come on at 1800 all I would see was white pics for 3-4 hours then it would be dark and all OK.
Like my last 550 cam I have been running this one on ext battery. All ws good for a few days then the cam stopped working . Plug in the remote just a blank lite screen . Unplug the ext battery cam fires right up 3/3 for power. plug in the remote again and blank lite screen again. Tested the battery.4.5 volts. Maybe low but the low power blue LED didn't come on and the unit didn't switch to internal batteries.
Any ideas???
