Video door phone set DAHUA KTP01-S2 2-wire connection, firmware 1.0.01.15.11804

DAHUA KTP01-S2 is a video door phone set built for entry control that uses a 2-wire connection to link an outdoor station with an indoor monitor. Supplied with firmware 1.0.01.15.11804, the system enables audio–video communication and remote door release while keeping wiring requirements minimal. The compact configuration is intended for residential and small commercial installations where reliable visitor verification and simple operation are needed.

Advantages

The 2-wire connection reduces installation complexity and cost compared with multi-core or networked alternatives, allowing retrofit into existing wiring. Audio and video transmission between the outdoor unit and indoor monitor provides clear identification of visitors. Integrated door release functionality supports convenient access control from the indoor station. The set’s firmware ensures defined feature behaviour and compatibility within the DAHUA ecosystem as intended for this model.

Suitable for

• Apartment entrances and individual flats
• Small offices and retail premises
• Renovation projects where existing two-core wiring is retained
• Locations requiring basic remote door release and visitor verification

Key specifications

• Connection type: two-wire interconnection between outdoor station and indoor monitor
• Functionality: audio and video communication with remote door release support
• Intended installation: residential and small commercial environments
• Power and signal over the same two-core wiring (as designed for the set)
• Firmware version supplied with the unit: 1.0.01.15.11804 (controls feature set and compatibility)

How to use

Mount the outdoor station at the entrance and install the indoor monitor in a convenient interior location. Connect the two devices using the provided two-core wiring according to the manufacturer’s connection diagram, ensuring correct polarity and secure terminations. Power up the system and allow it to complete any firmware initialisation. Use the indoor monitor to view the outdoor camera feed, communicate with visitors via intercom, and operate the door release mechanism from the monitor when access is granted.

Usage recommendations

For reliable performance, follow the manufacturer’s installation instructions, use appropriate two-core cable rated for low-voltage communication, and ensure connections are protected from moisture. Verify that the supplied firmware version meets any site-specific compatibility requirements before integrating with other DAHUA devices.
