The Chuango G5 Plus alarm system is the updated version of the Chuango CG-G5. The alarm system now has better security, including jamming protection: a secure signal between the base panel and the sensors. The moment the signal is interrupted, you'll receive an SMS message on your phone. The alarm also goes off immediately with an audio signal of 110 decibels. You can use the RFID tag to switch the system on and off. You can make it even easier for yourself by scheduling the alarm system to switch on and off automatically. The system works with a GSM SIM card that you slot into the control panel. The alarm system consists of 2 magnetic contacts, a motion detector, 2 remote controls, 2 RFID tags, and a control panel.
