ESIM420 – Gate controller

The ESIM420 is a simple device that incorporates a 4G/3G/GSM modem and allows the opening of doors and access barriers through a simple missed call at no cost. The device has 2 relays and 3 digital inputs whose state changes can trigger the sending of an SMS. The unit features an internal database that can store up to 2000 phone numbers whose calls allow the door or barrier to be opened. The unit can be configured locally via an application through the USB port, remotely via the Internet through a GPRS connection, or also through SMS messages. The relays can also be activated via smartphone (Android and/or iPhone) by installing a widget, without the need to dial any phone number. The ESIM420 is especially suitable for opening access doors of residential complexes, community garages, or even campgrounds.
