What is the Dahua VTM128 used for?

The VTM128 is a three-module mounting box for Dahua’s VTO4202F-X modular video-intercom family. It provides the rear enclosure needed to install three compatible modules in one vertical assembly. The box is designed to be used with the VTM126 three-module front panel. Door-station modules, front panel, power, cabling and installation services are not included unless separately stated.

Which Dahua intercom products are compatible with the VTM128?

Dahua lists the VTM128 as applicable to the VTO4202F-X modular door-station series and specifies that it is used with the VTM126 three-module panel. It should not be treated as a universal box for unrelated Dahua villa or apartment stations. Confirm every selected camera, keypad, card-reader, display or button module against the VTO4202F-X system before ordering.

Does the VTM128 support surface mounting and flush mounting?

Yes. Dahua’s official datasheet states that the VTM128 supports both surface-mount and flush-mount installation. The finished method depends on the wall construction, required appearance, cable route and installation depth. Flush mounting needs a correctly sized wall opening, while surface mounting leaves the 68mm-deep box visible and requires suitable anchors and weather sealing for the site.

What are the dimensions of the VTM128 mounting box?

The official dimensions are 133mm wide, 333.4mm high and 68mm deep. Check the complete wall area and cavity before cutting or drilling, including the VTM126 front panel, module clearances, cable bends, connector space and sealing. The dimensional drawing should be reviewed by the installer because the visible panel and recessed opening are not necessarily identical to the external box dimensions.

What material and colour is the mounting box?

The VTM128 uses an aluminium panel construction and has a silver appearance. Aluminium keeps the enclosure relatively light and provides a coordinated finish with compatible modular intercom hardware. Outdoor durability still depends on the complete assembled station, surface finish, sealant, cable entry and environmental exposure. Coastal, industrial or persistently wet sites may require additional corrosion planning and maintenance.

Is the VTM126 front panel included with the VTM128?

No. Dahua describes the VTM128 as a three-module mounting box used with the VTM126 panel, which means the front panel is a separate system component unless a seller explicitly packages them together. The compatible VTO4202F-X modules are also separate. Check the complete bill of materials so the enclosure, panel, modules, power components, network equipment and fixing hardware are all accounted for.

Does the VTM128 have an IP weatherproof rating?

Dahua’s official VTM127/VTM128 datasheet does not publish a standalone IP rating for the mounting box. Weather protection depends on the completed modular door station, selected panel and modules, wall preparation, cable entry, drainage and sealant. Do not describe the empty box itself as waterproof. Exposed outdoor installations should follow the relevant module installation guidance and use suitable sealing materials.

What should I confirm before ordering this three-module box?

Confirm that the project uses VTO4202F-X modules, requires exactly three module positions and includes the matching VTM126 front panel. Decide between surface and flush mounting, then verify wall area, cavity depth, cable routing and environmental sealing. Security Wholesalers can assist with checking the module combination and ensuring the mounting box, panel and intercom components form a complete compatible assembly.

Description

Product SKU: DH-VTM128

Product Overview

The Dahua DH-VTM128 VTM128 is a silver aluminium three-module mounting box designed for VTO4202F-X modular video-intercom door stations. It provides one vertical enclosure for three compatible intercom modules and is intended to be used with the separately selected VTM126 three-module front panel. Dahua specifies both surface-mount and flush-mount installation, allowing the box to sit on the face of a suitable wall or within a correctly prepared recess. The enclosure measures 133 × 333.4 × 68mm. Camera, keypad, card-reader, display and call-button modules are selected separately. Dahua does not publish a standalone IP rating, operating-temperature range or product weight for this mounting box.

Key Capabilities

Three-Module Capacity

Provides one vertical enclosure for three compatible VTO4202F-X modular intercom components.

Surface or Flush Mounting

Supports installation on the wall surface or within a correctly prepared recessed opening.

VTM126 Panel Compatibility

Designed to work with the matching Dahua VTM126 three-module front panel.

VTO4202F-X Modular System

Supports compatible camera, keypad, card-reader, button and display modules within the approved VTO4202F-X architecture.

Aluminium Construction

The silver aluminium build provides a lightweight, purpose-designed enclosure for modular intercom installation.

Tall Vertical Format

The 333.4mm-high form allows three modules to be arranged in a compact single-column entrance station.

Best For

Three-Module Door Stations: Houses three compatible VTO4202F-X modules in one vertical entrance assembly.
Surface-Mount Projects: Supports installation on a suitable wall where a recessed cavity is unavailable or undesirable.
Flush-Mount Projects: Can be recessed for a lower-profile architectural finish when the wall is prepared correctly.
Custom Intercom Combinations: Allows installers to combine compatible video, calling and access-control modules.
VTM126 Panel Assemblies: Provides the rear mounting box required for the matching three-module front panel.

Why Choose the VTM128

The VTM128 provides a purpose-built enclosure for projects that require three VTO4202F-X modules in a single-column entrance station. Supporting both surface and flush installation makes it useful across new construction and retrofit sites, while aluminium construction and a silver finish coordinate with the modular intercom range. The 333.4mm vertical format accommodates more functionality than a one- or two-module box without moving to a larger multi-column arrangement. Supplied by Security Wholesalers, it should be ordered only after confirming the VTM126 panel, exact module combination, mounting method, cable route and weather-sealing requirements.

Buyer Decision Tips

Compatibility Tip: The VTM128 is the rear mounting box, not the complete modular station. Include the matching VTM126 front panel and confirm that every selected module belongs to the VTO4202F-X system.

Mounting Tip: Review the official dimensional drawing before cutting a flush recess. Allow for the full box depth, cable bends, module connectors, wall structure, drainage and sealing.

Surface-Mount Retrofits

Provides an option where cutting a full recessed cavity is impractical but a secure wall surface and suitable cable route are available.

Flush-Mount Architectural Projects

Allows a lower-profile finish when the wall can accept the required recess and the matching panel is installed correctly.

Custom Three-Module Configurations

Suitable where the entrance requires more functions than a one- or two-module station but does not need a larger multi-column assembly.

Choosing the Right Model

Choose the VTM128 if: The entrance requires three compatible VTO4202F-X modules in one vertical column.
Choose the VTM127 if: Only two compatible modules are required in the station.
Choose a larger modular arrangement if: The project needs more than three module positions or multiple columns.
Choose surface mounting if: The wall cannot accept the required recessed opening or retrofit work must be minimised.
Choose flush mounting if: A lower-profile appearance is required and the wall can accommodate the box and cable depth.
