What is included in the Dahua DHI-KTX03-S2 intercom kit?

The DHI-KTX03-S2 package includes one DHI-VTO2023S 2-wire hybrid villa door station, one DHI-VTH2123GW-W-S2 2-wire Wi-Fi hybrid indoor monitor, one VTNC1003C-D 2-wire controller, one power adapter and one power cord. Door-lock hardware, cabling, microSD storage and installation labour are not listed as part of the kit.

Can I answer visitors and unlock the door from my phone?

Yes. The indoor monitor supports DMSS app connectivity for calls, monitoring and remote door unlocking after the system has been correctly installed, networked and added to the app. Remote functions depend on internet access, compatible mobile software, account configuration and the connected lock arrangement. Local access through the indoor monitor remains available when the system is operating on-site.

What unlock methods does the DHI-VTO2023S door station support?

The DHI-VTO2023S supports IC card, personal password and remote unlocking. Its built-in card reader stores up to 100 cards, and cards can be issued locally at the door station. The keypad includes Braille markings. A suitable electric lock, exit button and door-status arrangement must be selected and wired according to the installation design.

Is the outdoor door station weather and impact resistant?

Yes. The DHI-VTO2023S door station carries IP65 weather protection and an IK08 impact rating. It is specified for outdoor operation from –40 °C to +60 °C. Correct surface mounting, cable sealing and weatherproof termination remain essential, especially where the unit is exposed to rain, direct sun or temperature extremes.

Does the indoor monitor record visitor messages?

Yes. The DHI-VTH2123GW-W-S2 can record visitor video messages and capture snapshots when a compatible microSD card is installed. The monitor supports microSD storage up to 64GB, but a memory card is not listed as included. Storage capacity, card quality and recording settings will affect how much footage or how many snapshots can be retained.

Can extra indoor monitors be added later?

The DHI-VTH2123GW-W-S2 lists support for up to four extensions, allowing a larger compatible two-wire hybrid installation to serve multiple rooms or internal locations. Expansion requires suitable system design, addressing, controller capacity, wiring and power considerations. Additional monitors, door stations and related accessories are not included in this one-monitor kit.

Can this kit display other security cameras?

The indoor monitor supports monitoring of compatible door stations and can connect to supported HDCVI cameras. The associated two-wire hybrid platform also provides monitoring functions for compatible camera sources when correctly configured. Camera compatibility, wiring, power and video format should be checked before adding surveillance cameras to the intercom system.

What should I check before ordering the KTX03-S2 kit?

Confirm that the property is suitable for a two-wire hybrid installation, that the required lock and exit hardware are compatible, and that 2.4GHz Wi-Fi or the planned network connection is available for app features. Also check cable routes, mounting locations and storage requirements. Security Wholesalers can assist with confirming the system layout and required installation accessories.

Product Overview

The Dahua DHI-KTX03-S2 is a complete 2-wire hybrid video intercom kit for homes, villas, gated entries and small commercial premises that need touchscreen visitor communication with app access. The package combines a DHI-VTO2023S metal keypad door station, a DHI-VTH2123GW-W-S2 7-inch Wi-Fi indoor monitor and a VTNC1003C-D two-wire controller with the required power adapter and cord. Visitors can call from the outdoor station, while occupants view and speak with them from the touchscreen or configured DMSS app. Entry can be authorised by IC card, personal password or remote unlock. The outdoor unit adds a 2MP camera, automatic infrared illumination, tamper detection and IP65/IK08 protection, while the indoor monitor supports microSD recording, alarm connections and future monitor extensions. Electric lock hardware, cabling and microSD storage are not listed as included.

System Capabilities

Complete 2-Wire Hybrid Entry System

The door station, indoor monitor and dedicated controller are supplied together, giving installers the core components required for a single-entry video intercom system based on Dahua’s two-wire hybrid platform.

7-Inch Touchscreen Control

The indoor monitor uses a 7-inch capacitive touchscreen with 1024 × 600 resolution, providing a clear interface for answering calls, viewing visitors, unlocking the door, checking records and adjusting intercom settings.

App Calling and Remote Unlock

The monitor connects to 2.4GHz Wi-Fi and supports DMSS app functions, allowing authorised users to receive calls, monitor the entrance and unlock the door remotely after the network and account setup is completed.

Keypad, Card and Remote Entry

The outdoor station offers IC card, personal password and remote unlock methods. Its keypad includes Braille markings, and the local card database supports up to 100 credentials.

Outdoor-Rated Metal Door Station

An aluminium-alloy front panel, automatic infrared illumination, tamper alarm, IP65 weather protection and IK08 impact resistance suit exposed residential and small commercial entry points.

Expandable Indoor Coverage

The indoor monitor supports up to four extensions, giving suitable properties a path to add compatible monitors for bedrooms, upper levels, offices or other internal locations as the system grows.

Best For

Homes and Villas: Provides one outdoor call point and one central touchscreen for visitor screening and controlled entry.
Pedestrian Gates: Supports keypad, IC card and remote unlocking when paired with suitable lock and exit hardware.
Small Offices and Clinics: Lets reception or staff answer visitors and release a controlled door without leaving the work area.
Selected Retrofit Projects: The two-wire hybrid design can suit existing cable routes after the cable condition, length and topology are verified.
Properties Requiring App Access: DMSS connectivity supports remote calls, monitoring and unlocking after correct network setup.

Why Choose This Kit

The DHI-KTX03-S2 gives buyers a coordinated entry system rather than separate components that still need to be matched. Its 7-inch touchscreen is easier to use than a basic audio handset, while the outdoor station provides three practical unlock methods and a physical keypad with Braille markings. Compared with an app-only doorbell, the kit keeps a dedicated indoor monitor available for local operation and adds controller-based lock connections, door-status detection and exit-button support. The included two-wire controller and power accessories simplify the core equipment list, although cabling, lock hardware and storage still need to be selected for the site. Available through Security Wholesalers, this kit is best suited to a professionally planned single-entry installation where expansion to additional compatible monitors may be required later.

Package Inclusions

1 x DHI-VTO2023S – 2-wire Hybrid Villa Door Station
1 x DHI-VTH2123GW-W-S2 – 2-wire Wi-Fi Hybrid Indoor Monitor
1 x VTNC1003C-D – 2-wire Controller
1 x Power Adapter
1 x Power Cord

Buyer Decision Tips

Wiring Tip: A two-wire label does not guarantee that every existing cable can be reused. Confirm conductor type, cable condition, distance, topology and local electrical requirements before planning a retrofit installation.

Door Hardware Tip: The kit includes the intercom components and controller, but the electric lock, exit button, door contact, cabling and microSD card are not listed as included. Select these parts to suit the door, gate and access requirements.

Recommended Use

Front Door or Entry Gate

Mount the DHI-VTO2023S where visitors can comfortably reach the call button, keypad and card reader while the camera has a clear view of the approach.

Hallway or Main Living Area

Place the 7-inch indoor monitor in a central location where occupants can hear calls, view visitors and reach the touchscreen without crossing the property.

Two-Storey Homes

The system’s extension capability makes it suitable for properties that may later add compatible monitors upstairs, near bedrooms or in a home office.

Small Offices and Clinics

Reception or staff can screen visitors and unlock a controlled entrance from the touchscreen or configured app without leaving the work area.

Gated Residential Properties

The outdoor station’s keypad, card reader and remote unlocking options suit pedestrian gates where a compatible electric lock and cable route are available.

Renovations Using Two-Wire Cabling

The hybrid two-wire architecture can suit selected retrofit projects, but existing cable type, condition, distance and topology must be checked before reuse.

Choosing the Right Kit

Choose the DHI-KTX03-S2 if: You need one keypad door station, one 7-inch touchscreen, app control and a supplied two-wire controller for a single entry.
Choose a simpler kit if: You only need basic indoor calling and do not require Wi-Fi, app access, IC cards or a keypad.
Plan an expanded system if: The property requires multiple door stations, several indoor monitors or integration with additional compatible cameras.
Choose an IP intercom system if: New network cabling is available and the project is designed around Ethernet switching rather than the two-wire hybrid platform.
Confirm the lock design: The door or gate hardware must match the controller outputs, security requirements and fail-safe or fail-secure operation needed at the site.
