Size of Kerui™

Home security system shouldn’t be expensive.
It should be smart.


KERUI™ is a wireless door/window alarm system that detects if the door or window has been opened. What makes this system outstanding comparing to other alarm systems is that you’ll receive instant notification on your phone if someone breaks-in into your house or office.


Door Separation Alarm
The system consists of two magnetic sensors, which are places on the doors or windows. When the distance between the magnet and the transmitter is more than 1cm, the transmitter launches alarm signal to scare the intruders away.

Receive alerts on your phone
When the sensor detects door/window motion, it sends the SMS notification to the host’s phone. It helps to significantly increase the chances for saving your belongings by timely calling the police to catch the thieves.

Door Unclosed Reminder
If the door sensor is in separation state, the alarm host can’t be armed when you go out and intend to arm it, and the host voice prompts “Zone XX is open” to remind you that the door isn’t closed well.

Low-voltage reminder
When wireless door sensor has low voltage, it will flashlight once every 3s and send a low voltage signal to the alarm panel. Alarm host will voice prompt “Zone XX is in a low power” to remind you to change the batteries.

Note: The product can work with the alarm system as well as independently. It will send an alarm to control the host as soon as the door or window is open
