tango99999's review of Alertgen C7 GSM Alarm

★★★★☆

“Great, but quite a security flaw”

Written on: 02/04/2013 by tango99999 (1 review written)

Like:
Able to txt commands, including arm and disarm
Receive txts telling you of low battery or tampering with the system
Easy setup
Good looks


Dislike:
Security hole, if anyone knows your SIM card phone number, they can disarm your entire alarm system by sending a '0' to that number, very insecure.
You can find out the SIM card number by dialling your own number from the keypad and checking the caller ID!

Safeandsecure's Response to tango99999's Review

Wrong. Only stored mobile numbers can control the alarm control panel.
Anyway why would you give your alarm SIM card number to other people? It is doing this that is not secure. Don't blame the alarm for that.
