Telephone-initiated barrier entry
A walk-in guest can start an entry request by calling. The call itself does not open the barrier: access is requested through a personal link sent by SMS.
- The guest without a booking calls to request entry.
- The system sends an SMS with a link to enter and register, to use at the gate with an active vehicle presence sensor.
- The sequence entry-side sensor → barrier-open limit switch → exit-side sensor records the vehicle's arrival and the start of the stay.
Telephone and SMS services must be enabled and the configured barrier controller must pass a technical compatibility check. These services are disabled in the product-update screenshot; activation must be checked for each site. Measuring the stay does not imply automatic charging.
