B11 GSM/PSTN Dual-Network Alarm System
With a built-in LCD and touch keypad, Chuango B11 packs serious security functionality into a sleek panel with an elegant piano finish. Simply insert a regular working 2G SIM card into the B11 and plug in any PSTN fixed landline, and you double the security for your home and loved ones with system redundancy. It can be armed/disarmed via the keypad; a phone call or SMS text message from preauthorized phone numbers; remote controls; or smartphone app commands. Upon detection of intrusion, the B11 will sound the built-in siren and call out to you or monitoring center for appropriate action.

The intuitively designed Chuango B11 app interface enables you to effortlessly control the system via text messaging or GPRS: arm/disarm, home mode, remote voice memo or listening in. Multiple smartphone app owners can connect to and control one B11; or vice versa, multiple B11’s can be controlled by one smartphone app owner.
