The photodetector works through a mobile network, so thatIt takes seconds to send those snapshots to the Central. It sends them the same way we do from our mobile devices.

It is a very useful element for an alarm system, sincenot only prevents false alarms, but allows the CRA to get up and running quickly and provides information in the event of theft.
