4G Mobile Phone Gate Opener for Automatic Access

4G Premium GSM Gate Opener is a WH-120 PRO 4G based mobile access controller for automatic gates, barriers, garage doors, shutters and compatible relay-controlled access systems.

It uses a Nano SIM and caller-ID authorisation to activate a relay when an approved telephone number calls the unit. This removes the normal distance limitation associated with handheld radio remotes.

Published WH-120 PRO specifications support AC 9–30V or DC 9–36V power, a 3A/240V AC relay output, wired switch input and 50Ω SMA antenna. User capacity varies by exact version.
