KERUI Home Security System Review: Wireless PIR Motion Detector

Hi , I bought similar system (kerui X1). I'm in trouble with pir batteries. It didn't work properly with cheap batteries. I think it needs Duracell, energizer, etc..
How to use pir with micro usb ?
Can charge niMH batteries with pir ?
Which is first power supply at batterie+micro usb combination ?

I am guessing the cheap battery you mean heavy duty batteries. Yah. Don't believe the wording. Heavy duty batteries don't have enough juice. You'll need alkaline batteries.

My PIR has a microUSB port on the side, next to the power switch. See this photo:

I don't think the microUSB charges the batteries. But I don't know. Never tried it.

Bad news..
1- If you walk like a dog on the floor , it never detect you..
Also not pet illuminate pir (same like photo)..
Pir mounted 2 meters height on the wall ( I'm 85 kg 1.75 m )
2- Magnetic door sensor mounted iron door but couldn't signal to main unit only 2 meters..
My solution like this (don't cover antenna hole )
