Elsema G4000 4G GSM Gate Opener & Access Controller
The Elsema G4000 is a 4G GSM gate opener and access controller designed to operate automatic gates, doors and other access systems using a mobile phone.
Instead of issuing every user with a physical gate remote, up to 2,000 authorised phone numbers can be stored in the G4000. An authorised user simply calls the G4000's mobile number. The unit verifies the caller ID, rejects the call so there is no call charge, and activates its voltage-free relay output to trigger the connected gate or door controller.
Operating over the Australian 4G/VoLTE mobile network, the G4000 can be accessed from anywhere mobile coverage is available. Users can also be added or removed remotely, making it particularly useful for apartment complexes, gated communities, commercial properties, Airbnb accommodation and other sites where access permissions regularly change.
