I have a cam in a room that requires the night vision to be on most of the time. The night vision seems to be causing the unit to over heat and show a solid black screen then drop connection. Over time it comes back but it takes minutes to come back. If the room has light the issues don’t happen. The IR is also so strong at short distance that when someone comes into view the IR lights wash out the persons face to the point that they almost look like glowing blobs.
