Why Zxtech PTZ reset itself Once a While

Different between Industrial and Home PTZ Camera

With professional cameras, they have this motor with a special position sensor. this mechanism ensures every turn of the camera is measured and there is no deviation on every degree it moves. This kinda camera is expensive. 

With home use cameras, the motor rotation is calculated by presets, it tells how much the motor should turn, but it doesn't correct itself every degree it turns. hence it will generate a very very small deviation every time it turns. After a while, the camera will have to go back to position 0 to reset its calculation and restart the circle again. That's what is causing the movement in the video. This is a default solution for any home PTZ camera out there.

Why some PTZ camera is so Cheap

There are many cheap cameras on the market, the cheap-ness comes with corner-cutting too. Zxtech could have used non-Sony chips and we could have used a plastic shell, but it will reduce longevity. Zxtech could use infrared only without white light, but in the night you will lose the colour enabled recording.Zxtech does believe in providing a good quality product and having those better components increase the product life much longer.
