Product SKU: DHI-VTH8642KMS-W
Product Overview
The Dahua DHI-VTH8642KMS-W is a 10-inch two-wire IP and Wi-Fi video intercom monitor designed for homes, apartments, offices and managed buildings requiring a large indoor touchscreen for visitor communication. Its 1024 × 600 capacitive display presents the connected door-station camera image when a visitor calls, while the built-in microphone and speaker support clear two-way conversations. Installers can select Dahua digital two-wire communication or a 10/100Mbps Ethernet connection, with 2.4GHz Wi-Fi also available for supported system arrangements. Six wired alarm inputs, one alarm output, RS-485, SOS messaging and text-information reception allow the monitor to form part of a broader building system. A microSD card up to 64GB supports visitor video messages. This indoor monitor requires a 48V DC power supply and is designed for surface mounting rather than outdoor or recessed installation.
Key Capabilities
Large 10-Inch Touchscreen
The 1024 × 600 capacitive touchscreen provides a larger operating area than a common 7-inch indoor monitor. This is useful where visitors, calls and supported intercom controls need to be viewed from a reception desk, hallway or central household location.
Two-Way Visitor Communication
A built-in microphone and high-performance speaker support two-way audio with visitors at the connected door station. Echo suppression helps improve voice clarity during normal intercom conversations.
Two-Wire, Ethernet or Wi-Fi Connectivity
The monitor supports Dahua digital two-wire communication and includes a 10/100Mbps Ethernet port, with one wired connection type selected for the installation. Integrated 2.4GHz Wi-Fi provides another supported networking option.
Visitor Video Messages
When a suitable microSD card is installed, visitors can leave video messages when occupants are unavailable. The monitor supports local storage up to 64GB, allowing message recording without relying only on immediate call answering.
Six Wired Alarm Inputs
Six alarm-zone inputs, one alarm output and RS-485 support a more integrated indoor installation. Any alarm input can also be used for a doorbell connection when configured for that purpose.
Building Communication Functions
The monitor can receive text information released by a compatible management centre and send SOS messages when configured within a supported building system. Customisable Do Not Disturb periods help manage calls during selected times.
Best For
- Homes and Townhouses: Provides a large central screen for answering entrance calls and speaking with visitors.
- Apartments: Supports building intercom functions, text information and compatible multi-monitor arrangements.
- Reception Areas: Gives staff a larger touchscreen for managing visitor calls from a desk or nearby wall position.
- Office Entrances: Supports two-way communication, doorbell input and wired alarm integration in an indoor workspace.
- Two-Wire Renovations: Suits compatible projects where Dahua digital two-wire communication is selected instead of Ethernet.
Why Choose the DHI-VTH8642KMS-W
The DHI-VTH8642KMS-W is better suited to buyers who want a larger indoor interface than a standard compact intercom monitor. Its 10-inch touchscreen provides more viewing and operating space, while digital two-wire, Ethernet and Wi-Fi options allow the system to be planned around different building layouts. The six alarm inputs, alarm output, RS-485 interface, SOS messaging and management-centre text information also make it more appropriate for integrated apartment or office installations than a basic call-only monitor. Available through Security Wholesalers, this model is a practical choice where screen size, visitor-message storage and flexible connectivity matter. Buyers should allow for the specified 48V DC power supply and confirm the complete door-station and extension-monitor arrangement before installation.
Buyer Decision Tips
Connection Tip: The monitor includes both a two-wire port and an Ethernet port, but one wired connection method is selected for the installation. Confirm the complete system topology before cabling the wall position.
Power and Storage Tip: Wi-Fi does not remove the need for the specified 48V DC power supply. A microSD card is also required separately if visitor video-message recording is needed.

Choosing the Right Model
- Choose this model if: A large 10-inch touchscreen, Wi-Fi, two-wire/IP flexibility and six alarm inputs are required.
- Choose a smaller monitor if: Wall space is limited and a compact screen is more important than the larger viewing area.
- Choose this model for message storage if: A microSD card up to 64GB provides enough capacity for the intended visitor-message workflow.
- Confirm the extension layout if: More than one indoor monitor will answer calls in the property.
- Confirm the power plan if: Wi-Fi is being used, because the monitor still requires its specified 48V DC supply.
FAQs
- Is the DHI-VTH8642KMS-W a 2-wire or IP video intercom monitor?
The DHI-VTH8642KMS-W supports both Dahua digital two-wire communication and IP networking. It provides one two-wire port and one 10/100Mbps Ethernet port, with one connection method selected for the installation. It also supports 2.4GHz Wi-Fi. The correct method depends on the door station, system topology, available cabling and power design, so the complete intercom layout should be confirmed before installation. - What can be viewed on the 10-inch touchscreen?
The 10-inch capacitive touchscreen has a 1024 × 600 resolution and displays the door-station camera image when a visitor calls. Users can operate supported intercom functions, review released text information and access configured system controls from the monitor. The exact menus and available actions depend on the connected Dahua door station, management platform and system configuration rather than the monitor operating as an independent security display. - Does the VTH8642KMS-W support two-way audio?
Yes. The DHI-VTH8642KMS-W supports two-way audio and includes a built-in microphone and high-performance speaker. Echo suppression helps improve voice clarity during conversations with visitors at the connected door station. Audio performance still depends on the network or two-wire connection, door-station hardware, installation environment and configured volume levels. It is designed for intercom communication rather than general room audio or continuous surveillance recording. - Can the indoor monitor connect through Wi-Fi?
Yes. The DHI-VTH8642KMS-W supports 2.4GHz Wi-Fi using IEEE 802.11b/g/n across 2412–2472MHz, with WPA, WPA2, WPA-PSK and WPA2-PSK security options. Wi-Fi can reduce the need for a separate Ethernet data cable at the monitor, but the unit still requires its specified power supply. Signal strength, network congestion and router placement should be checked at the intended mounting position. - Can the VTH8642KMS-W record visitor video messages?
Yes. The monitor supports visitor video messages when a suitable microSD card is installed. Its listed local storage capacity is up to 64GB. This is useful when occupants cannot answer a call, but storage duration and message behaviour depend on the configured intercom system and card capacity. The microSD card is not stated as included, so it should be selected separately if message recording is required. - How many alarm inputs are available on this indoor monitor?
The DHI-VTH8642KMS-W provides six wired alarm inputs, one alarm output and one RS-485 interface. Any alarm input can also be used for a doorbell connection. These interfaces can support a more integrated apartment or office installation, but compatible sensors, cabling and connected devices must be selected and configured separately. The monitor also supports sending an SOS message to a compatible management centre. - How many indoor monitors can be used in one system?
The listed extension capacity depends on the installation type. A villa system supports three extensions, while an apartment system supports two. For Wi-Fi intercom operation, the stated arrangement is one main monitor with two extension monitors. The final capacity and calling behaviour depend on compatible devices and system configuration, so provide the complete door-station and indoor-monitor list to Security Wholesalers when planning a multi-monitor installation. - Where should the DHI-VTH8642KMS-W be installed?
The DHI-VTH8642KMS-W is designed for indoor surface mounting in homes, apartments, offices, reception areas and managed buildings. It operates from -10°C to +55°C at 10%–95% non-condensing humidity and below 3000 metres altitude. The fixed wall position should provide convenient touchscreen access, a reliable Wi-Fi or wired connection and suitable cable routing. It is not listed as a weatherproof outdoor monitor.
