What hAlarm can do for you ?

hAlarm (stand for Home Alarme) is a small project to make a burglar alarm. It can recover an existing system by taking previous material such as detectors and alarm sirens but it could also be use on a new build installation.

It is web-based and run on top of a webserver using php. The front-end, the communication to read inputs and doing commands are purely software. It mean it may not be as reliable as a pure micro-controller system. But, i can reassure you, it's reliability will be more than enough for a residential.

The project need one or more IP device acting as keypad(s).

ProCon
Fully IP, access from LAN and WANRequiere technical skill
Neat interfaceConsume energy for the soft keypad
Intuitive keypad Depend on LAN availability

 hAlarm received the inputs information as JSON such as {"I0":"off", "I1":"off", "O1":"off"}
 Where I is for inputs and O are outputs status with 'on' or 'off' values.
 hAlarm command the outputs (relays for sirens, flash..) by software.

 hAlarm rely on communication(s) application(s) to read inputs and to command outputs, which are -not- part of this project.
