The alarm card is used to monitor objects.
For example if the sensor of the alarm card detects a movement an alarm is generated and automatically an SMS is send to varies mobile numbers.

Additionally an E-Mail can be automatically send.
SMS is used to configure the alarm card. With one SMS directed to the SIM of the alarm card the configuration is done.
The motion detector checks every 10 seconds.
This reduces the possibility of non-intruder caused alarms.
Accumulators keep the alarm card working for 3 days if the power supply is interrupted by power failure, or sabotage. The power status of the accumulators can be controlled via SMS. If the accumulators run out of power an SMS is generated automatically.
