I’ve been running 2 PTZ and 3 static cameras for almost a year (Jan 9 2019) outside. PTZ’s are under a porch roof but not enclosed at all. The static cams are on the side of the house in varying levels of exposure. One is directly exposed on a wall, the other 2 are up by the eave. They are maybe 6-8" back from the outside of the gutters. Two are plugged into GFCI outlets on the outer wall with the factory wire. All are using the magnet mount and factory mount onto vinyl. I did clean the vinyl very thoroughly. The cube/static cameras have been endured rain, sleet, snow, ice, wind, and wet leaves/debris.
I keep a spare cube and ptz in case of a problem but so far(knock on wood) they’re all working. The only real issue I have is keeping cob webs off the lenses.
The voltage regulators and power supply diodes should give off enough heat to keep everything warm enough for around here. I’m in the mid-atlantic region so we do get some cold snaps in the single digits sometimes.
I guess my point is that these are pretty robust for the cost. I understand them not recommending them to be used outside but I’ve had admirable results. I had a pair of Foscam 720p static mount cameras that failed when there was a lightening strike nearby. The Wyze camera on the same circuit was fine.
