IOS/Android APP Control KERUI Wireless G18 GSM SMS Home Alarm System Security

Wireless sensors have no range

I find that the wireless sensors have ridiculously short ranges. For example the sensor I have on the mail door is only 25feet from the main module and yet they cant communicate- and thats line of sight. I had another sensor placed down stairs and the module never could get a signal from it.- only when I brought it to the bottom of the saires did it register (main module is at the top of the staires 12 feet away)Read full review
