JC 433MHz Wireless Outdoor Motion Detector PIR Sensor Pet Immunity for Home Business Security Alarm System Waterproof IP65

I had this installed in the garden but wasn't fit for purpose as my small cat would cause the alarm to trigger despite it claiming to be immune to pet alerts for animals smaller then 20kg. I had it exchanged for a 2nd unit just in case the first was faulty but the 2nd unit had the same issue. Jcheng support wasn't able to help resolve the issue so I sent it back for a refund.

This easily adds to the Base unit and allows you to place protection in damp areas with no fear of false alarms.Caution: just take care if removing the circuit board to protect the antenna.

Didn’t last long, got other sensors that are outside also and work much better and lasting longer.This unit has been replaced once already.
