Independently of the usage of a reader camera this function allows for automated locking of the turnstile at the lift if the height sensor detects a tall person when a child ticket is used.

Access in this case will be blocked until the lift attendant performs a manual release after verifying the credentials of the person in question. This transaction will then be recorded as a normal access.

This function is recommended e.g. in cases where small children usually receive free tickets for lift access, and any misuse of those tickets is to be prevented.
