PTZ ip camera troubles

[BellaminoBoy]

I have a strange problem with a generic IP Wi-Fi PTZ camera. The camera is located on a horse stall, powered from 4S40P Li-Ion pack charged by MPPT and 240 W solar panel. The thing s installed a switch on my solar distribution box to turn off the camera on low sunlight, rainy days so it does not discharge my battery (i need it also for light, door openers, fence energizer etc...). Just a simple push rocker switch, nothing special (planned to replace by a adjustable low voltage cut off module, just did not have time to make one yet).

I noticed PTZ function stopped working immediately and camera draws 2.5 A instead of 900 mA as usually. After few trips to the roof, taking down the camera i noticed it worked every time in my lab, but not on my stall roof. Then i realized if i remove switch and hard-wire the camera, it works perfectly. As soon i put the switch back, camera PTZ function stops working and current draw goes from 900 mA to 2.5A. I can view the image online, but can't move the camera or zoom. Also, when wired to switch camera does not perform its reset, moving in all directions when power is applied. If hard-wired it will normally move in all directions and center. So ok, maybe the switch is defective, having some abnormal resistance. I put a new switch, same. I put three types of other new switches, same happens. I put a new relay instead of switch, same. I tried measuring resistance of switches, the resistance is so low i even dont have equipment to measure it.

I have been troubling this problem for some days and cant find out what could be the issue. It is almost mistical problem, that i cannot believe myself.

It sounds like it's trying to home but stays stalled.
The root cause could even be something mechanical.
You need to monitor the voltage directly at the camera.
