Night vision on 1 camera shuts off right away

[Hahnle]

My night vision on 1 of my cameras turns on briefly and than shuts off almost right away and cannot see much when recording

It may be the camera needs to be reset... pull battery and replace. ( it should self sync if close enough to base )

OR

The Night Vision does check for ambient light... is it possible that the camera sees some light from a nearby source and is turning off the LEDS due to same.  ( you can test the camera by placing in a dark room/closet/etc and see if the leds stay on )
