JC Wireless 433Mhz Signal Amplifier Repeater for Alarm System

Had issues with losing signal from exit sensors of Simply Safe security system. Large house and a lot of electronic signals around - WiFi, phone etc. Had repeated issues with having to reset or reinitiate connections with sensors, exit sensors in particular. Solutions on-line mostly had to do with extending internal antenna's which permanently modified the sensors. Tried this device, placing it in a central area between the base station and most remote sensors. Has reduced instances of lost signal by more than 95%, maybe more like 99%. Just plugged in with no modifications. Boosts all signals at 433 mhz. Clean simple solution.

Este producto es solo para alarmas de panel si tienes una alarma wifi pero sin panel no lo vas a poder programar, un poco más de descripción

We wanted to put a pir sensor in garage but garage was about 80 m away this little repeater unit relayed the signal from the pir in the garage back to the alarm no problem I would very highly recommend jcheng products also absolutely brilliant aftersales if you need help or information thanks again

I tried various devices that use the 433 MHz frequency and none were detected when this unit was in learn mode. VERY DISAPPOINTING
