If the camera gets snow or ice buildup in such a way to cause the camera to have trouble moving, the PTZ settings will get out align when a move attempt is made.
PTZ reset fixes this.
I've seen this with my PTZ.
During a snow storm, I try to position my ptz in such a way to minimize any buildup on it.
Sometimes that works, sometimes it doesn't.
Best bet, if you know it's bound up by snow/ice, don't try to use the PTZ. Let the sun do it's job.
Camera Shifted on me again and tried a PTZ reset and the presets went back to original position. It may be the cold weather or snow/ice. Camera is on a tower 30 ft. high in cold canadian winter.
Camera still giving trouble. But now PTZ doesn't work, works but with long latency. I always have to reset camera, than it works as it should. Any ideas. I'm using blue iris.
