I purchased two of these cameras and installed both outdoors almost a year ago. One of them receives direct sunlight for about 5-6 hours a day, while the other only gets 1-2 hours.
The one which get 5-6 hours direct sunlight keeps restarting 10-15 times per day. I switched the video encoding from H.265+ to H.264+, since H.265+ is more processor havey, and I also lowered the bitrate. That made it a bit more stable, but it still restarts multiple times a day. I’ve also tried changing the cable and using a different switch port, but the issue remains the same.
The other camera, which gets only 1–2 hours of direct sunlight, doesn’t have this issue at all.

Super packaging and quick shipping through standard courier service. Devices are new with company seal. It works good at 30fps at any mp even at 5mp, no need NVR if we put memory card.need to buy power adaptor or poe switch separately. It’s not wifi support camera so don’t expect that feature. Overall good.
