Intercom Handset Commax DP-3HP – audio unifon for video door phone systems, Commax DP-3HP

The Commax DP-3HP is an audio unifon (handset) developed for integration with compatible Commax video door phone systems. It provides clear two-way voice communication between the indoor unit and the door station, allowing residents or staff to speak with visitors, answer calls, and control entry. The compact design and straightforward interface make the DP-3HP suitable for residential and small commercial installations where an audio-only handset is required alongside a video system.

Advantages

The DP-3HP offers reliable voice transmission and intuitive call handling in a compact form factor. Its compatibility with Commax video door phone panels ensures seamless integration with existing systems, and the handset design isolates indoor audio for private conversations. Installation and routine use are simple, reducing the need for frequent adjustments or technical support.

Suitable for

• Homes with Commax video door phone systems that require a dedicated audio handset.
• Small offices or reception areas where staff need to communicate with visitors at the entrance.
• Multi-room apartments or properties where an additional indoor voice unit is needed.
• Installations where a compact, wall-mounted indoor handset is preferred over freestanding devices.

When it may not be suitable

The DP-3HP is an audio-only handset and does not include a video display; it is not suitable when visual verification of visitors is required at the indoor unit. It also requires a compatible Commax door phone panel and wiring; it will not function as a standalone intercom or with non-Commax systems unless declared compatible by the system manufacturer.
