As with all Daitem equipment, the mobile doorphone benefits from ultra-reliable radio transmission. Patented under the name DynaPass®, this innovative technology protects radio communications from interference and jamming and hence provides an optimal link between the outdoor caller unit and the handset.
At the start of communication, the patented DynaPass® system selects a free radio channel. If there is any interference on this channel, the system is automatically synchronised with another, more available channel. This means you can be sure to have optimal communication whatever the environmental conditions.
