4G LTE GSM Access Control System for Gates, Garage Doors & Barriers
The MHK 4G GSM Gate Opener Controller is a powerful and intelligent access control solution designed for automatic gates, garage doors, parking barriers, bollards, rolling shutters, access doors, and industrial equipment. Using advanced 4G LTE, 3G, and GSM network technology, users can operate automation systems from anywhere simply by making a phone call or sending an SMS.
The controller works with a Nano SIM card and automatically rejects calls from authorized users while activating the relay output on the first ring. This allows completely free operation with no call charges and eliminates the need for remote controls, key fobs, or access cards.
Designed for residential villas, gated communities, commercial properties, warehouses, factories, farms, parking facilities, and industrial sites throughout Dubai, Sharjah, Abu Dhabi, Ajman, and across the UAE, the MHK 4G GSM Gate Opener provides secure, reliable, and modern access management.
With support for up to 200 or 1200 authorized users depending on configuration, administrators can easily add or remove users through SMS commands. Caller ID verification prevents unauthorized access, while SMS notifications provide confirmation of relay actions for enhanced security and monitoring.
