The indoor monitor offers a 4″ TFT-LED screen and up to 16 polyphonic tunes. Choose between a 1-3 button outdoor video station if there are up to 3 different households using the same entrance. Alternatively, one outdoor video station can house 3 indoor monitors. The gate unlocking function is optional, and not included in the pack. It does, however, have a 12DC output for powering an external relay.
