Product SKU: DHI-VTH2621G-P
Product Overview
The Dahua DHI-VTH2621G-P is a black 7-inch IP indoor monitor designed for compatible residential, apartment and commercial video intercom systems. Its 1024 × 600 capacitive touchscreen provides a clear interface for answering intercom calls, viewing supported door stations and IP cameras, receiving management-centre messages and managing connected alarm functions. Two-way audio is supported through an audio input, built-in speaker and echo suppression, while H.265 and H.264 decoding helps display compatible video streams efficiently. Six alarm inputs and one alarm output allow the monitor to participate in a broader security or doorbell arrangement. Standard PoE can carry network and power through one Ethernet cable, with 12V DC also supported. The DHI-VTH2621G-P is a wired indoor surface-mount model; Wi-Fi is not listed for this variant, and its microSD slot is identified as reserved for software rather than general surveillance recording.
Key Capabilities
7-Inch Touchscreen Interface
The 7-inch TFT capacitive touchscreen provides a clear control point for intercom calls, supported video viewing and system functions. Its 1024 × 600 resolution suits everyday door-entry use without requiring separate navigation buttons.
Two-Way Intercom Audio
An audio input, built-in speaker and echo suppression support two-way conversations with compatible door stations. G.711a, G.711u and PCM audio formats help the monitor operate within supported digital intercom environments.
Door Station and Camera Viewing
The monitor supports compatible door stations and IP cameras with H.265 and H.264 decoding. This allows residents or staff to use one indoor screen for visitor communication and selected video monitoring.
Standard PoE Installation
Standard PoE can deliver network connectivity and power through one cable, reducing the need for a nearby power outlet. A 12V DC input is also available where the installation does not use a compatible PoE source.
Alarm and Doorbell Integration
Six alarm inputs and one alarm output allow the monitor to participate in a compatible alarm arrangement. Any alarm input can also be configured as a doorbell input for a local call or notification function.
Multi-Monitor System Support
The listed extension capacity supports up to nine monitors in a villa configuration and four in an apartment configuration. This suits properties requiring intercom answering points in several rooms or areas.
Best For
- Homes and Villas: Provides a central touchscreen for compatible entrance calls, camera viewing and alarm-zone functions.
- Apartments and Strata Properties: Supports multi-monitor configurations and management-centre information within compatible digital intercom systems.
- Offices and Reception Areas: Gives staff a convenient indoor point for answering visitor calls and viewing supported entrance cameras.
- Multi-Level Properties: Allows compatible extension monitors to be positioned at practical answering locations around the building.
- Wired PoE Installations: Uses one network cable for communication and power when connected to a compatible standard PoE source.
Why Choose the DHI-VTH2621G-P
The DHI-VTH2621G-P is better suited to buyers who want a straightforward wired indoor monitor with a larger touchscreen, PoE power and alarm integration. Unlike a basic audio-only handset, it can display compatible door stations and IP cameras, support two-way voice communication and receive text information from a management centre. Six alarm inputs also provide more integration flexibility than a simple call-answering screen. Available through Security Wholesalers, this model should be selected as part of a confirmed Dahua intercom design rather than treated as a universal replacement monitor. Buyers should note that Wi-Fi is not listed for this P variant, the screen is 1024 × 600 rather than Full HD, and the microSD slot is reserved for software rather than general-purpose recording.
Buyer Decision Tips
Network and Power Tip: Choose this P variant when a wired 10/100Mbps Ethernet connection is available. It supports standard PoE or 12V DC, but Wi-Fi is not listed for this model.
Storage and Compatibility Tip: Do not assume the microSD slot provides local CCTV recording. It is identified as reserved for software, and the leave-video function requires an SD card in the connected VTO door station.

Choosing the Right Model
- Choose this model if: The project needs a black 7-inch wired IP monitor with PoE, two-way audio and six alarm inputs.
- Choose a Wi-Fi model if: A wired Ethernet connection cannot be provided at the mounting location.
- Choose a larger monitor if: A bigger display is required for frequent camera viewing or accessibility needs.
- Confirm compatibility first if: The monitor is replacing an existing indoor station or joining a mixed intercom system.
- Confirm the extension layout if: More than one indoor answering point is required throughout the property.
FAQs
- What is the DHI-VTH2621G-P used for?
The DHI-VTH2621G-P is an indoor IP video intercom monitor for compatible door stations, IP cameras and management-centre systems. Its 7-inch touchscreen provides the local interface for answering calls, viewing supported video, two-way voice communication and alarm-zone functions. It is a system component rather than a standalone door station, so compatible intercom equipment, network configuration and power are required. - Does the DHI-VTH2621G-P have a touchscreen?
Yes. The monitor has a 7-inch TFT capacitive touchscreen with a resolution of 1024 × 600. This gives residents or staff a clear interface for intercom calls, video viewing and system controls without physical navigation buttons. The display is suitable for everyday door-entry use, but it is not a Full HD screen and should not be treated as a replacement for a dedicated surveillance monitor. - Does this indoor monitor support two-way audio?
Yes. The DHI-VTH2621G-P supports two-way audio and includes one audio input, a built-in speaker and echo suppression. Audio formats include G.711a, G.711u and PCM at 16kHz and 16-bit. Call quality still depends on the connected door station, network performance, system configuration and surrounding noise at both ends of the conversation. - Can the DHI-VTH2621G-P view door stations and IP cameras?
Yes. The monitor is designed to view compatible door stations and IP cameras and supports H.265 and H.264 video decoding. Interoperability includes ONVIF and SDK support, with RTSP, RTP and SIP among the listed network protocols. Compatibility should still be checked for the exact camera, door station, stream profile and firmware used in the installation. - How many extension monitors can be used?
The listed extension capacity is up to nine monitors in a villa configuration and four in an apartment configuration. The practical layout depends on the selected door station, project mode, network design and compatible intercom configuration. Before installation, confirm which unit will operate as the main monitor, how calls should be distributed and whether every planned extension is supported by the complete system. - What alarm connections are available?
The DHI-VTH2621G-P provides six alarm inputs and one alarm output. Any alarm input can also be configured as a doorbell input, allowing the monitor to participate in a compatible alarm or local-call arrangement. External detectors, buttons, relays and cabling are not stated as included, so the connected device type, wiring method and event actions need to be planned separately. - Does the monitor support a microSD card for recording?
The monitor accepts a microSD card up to 64GB, but the storage entry is identified as reserved for software. Buyers should not assume that it provides general-purpose surveillance recording. The leave-video function instead requires an SD card in the connected VTO door station. Recording, message and storage behaviour should be confirmed against the full intercom system and its firmware. - What should I confirm before ordering the DHI-VTH2621G-P?
Confirm the compatible door station, IP cameras, extension layout, alarm wiring, surface-mount location and power method. The monitor supports standard PoE or 12V DC, while Wi-Fi is not listed for this P variant. Security Wholesalers can review the proposed intercom components to identify likely compatibility, power, networking or extension-limit issues before installation.
