4G LTE GSM Gate Controller Auto Opener

This automatic gate access controller operates on 4G LTE networks (B1/B3/B5/B8 bands) and is powered by 12V DC at 1A. It features a robust metal housing with blue finish, designed for reliable outdoor use across temperatures from -10°C to +60°C (storage: -20°C to +60°C) and humidity levels of 10–90% non-condensing. The unit includes one 6A/240V AC relay output to control gates, garage doors, barriers, bollards, shutters or access doors; two digital inputs for door/motion sensors that trigger SMS alerts and siren activation when triggered; and supports up to 999 authorized phone numbers. Relay actions send editable SMS confirmations to the owner. User management — adding or removing numbers — is done via simple SMS commands. Caller ID authentication ensures only pre-approved numbers can activate the system, eliminating need for physical remotes.
