Based on GSM/3G/4G communication protocol, supports 999 authorized users. Authorized users can remotely control the equipment, systems and machines connected to the product by SMS commands & free calling. It is widely used in access control systems, garage doors, swing doors ,folding doors,sliding doors, parking system and the equipments that can be connected to the relay control , the G203 gate controller will send a notification (via SMS) to the user of the result of the remote control (such as the opening and closing status of the gate).
Most of the similar products on market use the second-hand communication modules on PCB board (such as the G202 gate opener, WH-120 gate opener, and WH-120 PRO gate opener, etc. they all use the second-hand communication modules), the second-hand communication modules will cause the device can not work normally ,sometimes caused big loss for property and potential security risk .for example communication off suddenly, commands can does not work, power chip burned, device crashes,etc
Our company's G203 gate controller use new components and applications to give customers a more stable and smooth operating experience in terms of hardware and software.
