I got 3 cameras IP2M-841B-V3.
Two of them go to PTZ preset 1 (or close to it) after e reboot, the 3rd goes anywhere, not where I like it to go. So it always needs to be repositioned.
Am I correct that preset 1 is supposed to be the home position? I cannot find anything about it in the manual.
And after some testing it looks as if the cam doesn't store the preset ... or only for a short time.


Am I missing something? Should I reset the device to factory defaults?
 
I have an IP2M-841B-V3 and IP2M-841W-V3, and the IP2M-841B-V3 recently started going to a different position than the last set position when powered off for awhile then powered back on. It seems to be an issue with its range of motion self-calibration on the power on. After it powers on and is pointing in the wrong position (usually pointed too low), if I use the PTZ controls to try to point it up, it gets stuck. I need to hold the down position for awhile, then switch to up to get it up go past the vertical angle that it was stuck on.

Resetting to factory default didn't help.

When the power down time is shorter, it seems to be able to "keep" the position more reliably, so I've been wondering if it's a problem with the CMOS battery. From my quick online search, the exact battery model was unknown, so I haven't tried a replacement yet.
