Burglar alarms that can notify your mobile phones when alarms are triggered. It can be achieved by either using a landline connection or simcard inside alarm that calls and/or texts you if someone tries to break in. For landline connection, physical connection to working landline using PSTN module inside alarm control panel is required. Landline connection through new digital landlines does not work for most customers. For simcard option, a GSM unit with a pre-paid or monthly contract simcard inside the panel is required.
