What is ET083?

It’s a universal cellular communicator which provides 2G/3G/IP connectivity to any intrusion alarm panel, reporting to alarm receiving centers while simultaneously keeping homeowners informed.

How ET083 works?

ET083 provides communication (GSM/GPRS, LAN) channels for any third party panel.
