## Description

desertcart.com : KERUI 433MHz Home Wireless PIR Infrared Motion Sensor Detector for Alarm System : Electronics

Review: El mejor detector de movimiento.Ideal para reemplazar uno que se te haya roto ó para agregarlo a tu sistema de seguridad.Fácil de instalar y programar.
Review: Works Great! - This motion sensor easily integrated into the other sensors I had already installed on my detatched garage. The price is excellent and it worked great under testing. I have had no false alarms under all weather conditions. The key is proper placement and make sure each of the other sensors have their contacts nice and close on each door/window. If the gap is too big, a small movement from wind or temp changes will trigger false alarms. The value for the Kerui alarm is excellent! A side note: This brand does a great job with their alarm speaker. It is super loud and perfect for a non-monitored system.

### ⭐⭐⭐⭐⭐ Simple and inexpensive alarm.
*by T***J on January 9, 2026*

Very easy to setup, works great and very loud alarm, it is just a simple alarm that tells you someone is in your home, or trying to get in, so far it has worked great, I have had a few different ones over the years but I find this the simplest one to use, it does not call anyone but the alarm wakes you up, yes I would recommend this for Home alerts.
