Product SKU: DHI-VTH2421FW-P
Product Overview
The Dahua DHI-VTH2421FW-P is a white 7-inch IP video intercom monitor designed for compatible homes, apartments, offices and other indoor door-entry systems. Its 1024 × 600 capacitive touchscreen provides a convenient interface for answering visitor calls, viewing supported door stations or IP cameras, receiving centre-issued information and accessing configured intercom functions. An omnidirectional microphone and built-in 1.5W loudspeaker support two-way communication, with echo cancellation and digital noise reduction helping maintain clearer conversations. Standard PoE allows compatible power and network data to share one Ethernet cable, while a 12V DC input provides an alternative power option. The monitor also offers six alarm inputs, one alarm output, SOS alarm support and capacity for up to nine sub-stations. MicroSD storage supports cards up to 32GB, with an 8GB standard capacity listed for compatible video and text message functions.
Key Capabilities
7-Inch Touchscreen Control
The 1024 × 600 capacitive touchscreen provides a practical indoor control point for visitor calls, entrance viewing, released information and supported intercom functions without requiring a separate handset or navigation keypad.
Two-Way Visitor Communication
An omnidirectional microphone and built-in 1.5W loudspeaker support bidirectional talk with compatible entrance stations. Echo cancellation and digital noise reduction help make conversations easier to understand in everyday installations.
Standard PoE Installation
Standard PoE can supply compatible network data and power through one Ethernet cable, helping simplify installation. A 12V DC, 1A input is also available where a separate power source is preferred.
Door Station and Camera Viewing
H.264 decoding and IPC surveillance support allow compatible door-station video and selected IP camera streams to be viewed from the indoor screen as part of a correctly configured Dahua intercom system.
Alarm and SOS Integration
Six switch-type alarm inputs, one alarm output and SOS alarm support allow the monitor to participate in a broader residential or commercial intercom and alarm arrangement.
Message and Extension Support
The monitor supports video or text messages, information released by a compatible centre, configurable do-not-disturb periods and up to nine sub-stations for convenient answering points around the property.
Best For
- Homes and Villas: Provides a central touchscreen for compatible entrance calls, visitor communication and supported camera viewing.
- Apartments and Strata Properties: Suits indoor answering locations where residents need video intercom, message and alarm functions.
- Offices and Reception Areas: Gives staff a convenient screen for communicating with visitors before granting access through the connected system.
- Multi-Level Properties: Support for up to nine sub-stations allows additional answering points to be included in a properly planned layout.
- PoE Intercom Installations: Standard PoE can reduce cabling by carrying compatible network data and power through one Ethernet cable.
Why Choose the DHI-VTH2421FW-P
The DHI-VTH2421FW-P is a practical alternative to a basic audio handset because it combines entrance video, touchscreen operation, two-way audio, message functions and alarm integration in one indoor device. Standard PoE makes it particularly useful for wired installations where a single Ethernet cable can supply both the network connection and power. The built-in microphone, 1.5W loudspeaker, echo cancellation and noise reduction support clearer visitor conversations, while the microSD storage and information-release functions add convenience for missed calls and building communications. Available through Security Wholesalers, this white monitor is best selected as part of a confirmed Dahua intercom design with compatible entrance stations, network equipment, alarm devices and extension monitors.
Buyer Decision Tips
Connectivity Tip: The supplied specification lists one RJ45 network interface and does not list Wi-Fi. Choose this model for a wired Ethernet installation, and select a confirmed wireless indoor monitor if Wi-Fi connectivity is required.
Compatibility Tip: Confirm the intended Dahua door station, number of sub-stations, alarm devices and PoE source before ordering. The monitor should not be treated as a universal replacement for an unrelated intercom screen.

Choosing the Right Model
- Choose the DHI-VTH2421FW-P if: You need a white 7-inch wired IP intercom monitor with touchscreen control, PoE, two-way audio, message storage and alarm integration.
- Choose the black variant if: The corresponding darker finish is better suited to the planned interior or equipment design.
- Choose a Wi-Fi model if: Ethernet cabling cannot be provided and wireless network connectivity is specifically required.
- Choose a different display if: The installation requires a larger screen or a dedicated multi-camera CCTV monitor rather than an intercom control panel.
FAQs
- Is the Dahua DHI-VTH2421FW-P suitable for a home or apartment video intercom system?
Yes. The DHI-VTH2421FW-P is an indoor IP video intercom monitor designed for compatible residential, apartment and similar door-entry systems. Its 7-inch touchscreen supports visitor calls, full-duplex two-way audio, message functions and viewing from supported door stations or IP cameras. Compatibility still depends on the selected entrance station, network design and system configuration, so the complete device combination should be confirmed before installation.
- Does the DHI-VTH2421FW-P have a touchscreen?
Yes. The monitor uses a 7-inch TFT capacitive touchscreen with a resolution of 1024 × 600. The screen provides the main interface for answering compatible intercom calls, viewing supported entrance video, reading released information and accessing configured functions. It is designed as an indoor intercom control point rather than a general-purpose high-resolution CCTV display.
- Can the DHI-VTH2421FW-P provide two-way audio?
Yes. The DHI-VTH2421FW-P supports full-digital, dual-way bidirectional talk through an omnidirectional microphone and built-in 1.5W loudspeaker. Echo cancellation and digital noise reduction are also supported. The available call functions and overall audio experience depend on the connected door station, network quality and system programming, so communication should be tested during commissioning.
- Can this indoor monitor be powered through PoE?
Yes. The DHI-VTH2421FW-P supports standard PoE through its RJ45 network connection, allowing compatible power and network data to use one Ethernet cable. It can also operate from a 12V DC, 1A supply. Confirm the available power source before installation, as using a wired network connection without a compatible PoE source still requires the separate DC supply.
- Can the DHI-VTH2421FW-P display compatible IP cameras?
Yes. The monitor supports IPC surveillance and H.264 video decoding, allowing supported IP cameras or compatible door-station video to be viewed from the indoor screen. It should not be treated as a universal CCTV monitor, because available camera views, controls and stream compatibility depend on the connected devices and the completed Dahua intercom configuration.
- How much microSD storage does the DHI-VTH2421FW-P support?
The monitor supports microSD storage up to 32GB and the supplied specification lists a standard capacity of 8GB. Storage supports functions such as leaving video or text messages within the compatible intercom system. Available recording and message behaviour depends on the connected door station and configuration, so confirm the required workflow rather than treating the monitor as a replacement for a CCTV recorder.
- How many alarm connections and sub-stations are supported?
The DHI-VTH2421FW-P provides six switch-type alarm inputs and one alarm output, together with SOS alarm support. The specification also lists support for up to nine sub-stations. The practical arrangement depends on the compatible door station, alarm devices, wiring and system programming, so all sensors and extension monitors should be included in the intercom design before installation.
- What should be checked before ordering the DHI-VTH2421FW-P?
Confirm the compatible Dahua door station, required number of indoor monitors, Ethernet cabling, PoE availability or 12V DC power, alarm connections and wall-mount position before ordering. The unit measures 119.6 × 221.5 × 21.5mm and is intended for indoor use. Security Wholesalers can help confirm whether the white monitor suits the planned intercom layout and connected devices.
