Product SKU: DHI-VTM121
Product Overview
For installers fitting the Dahua VTO7541G or VTO7521G 8-inch face recognition door station into a wall recess, the DHI-VTM121 flush mount plate provides the purpose-built bracket needed to achieve a clean, recessed finish. Designed specifically for these two door station models, it eliminates guesswork around compatibility and ensures a secure, professional installation at outdoor entry points. Featuring an operating temperature range of -30°C to +70°C, the VTM121 is rated for outdoor environments and will handle Australian climate conditions across a wide range of sites. With product dimensions of 373 mm x 143 mm x 67.5 mm and a gross weight of 1.1 kg, it is straightforward to handle during installation. This makes it a practical addition to any project where a surface-mounted door station appearance is not acceptable and a flush finish is required.
Key Capabilities
Purpose-Built Compatibility
Engineered specifically for the DHI-VTO7541G and DHI-VTO7521G door stations. Using a bracket designed for these exact models avoids alignment problems, uneven gaps around the faceplate, or structural issues that arise when generic brackets are used with precision-dimensioned door station housings.
Flush Mount Installation
Designed for recessed in-wall mounting, the VTM121 allows the door station to sit flush with the wall surface. This suits commercial entry points, apartment building lobbies, and office facades where a tidy, integrated appearance is expected and a protruding surface-mount profile is not suitable.
Outdoor-Rated Operating Range
Rated for outdoor use with a confirmed operating temperature range of -30°C to +70°C and operating humidity between 10% RH and 90% RH. The bracket is suited to exposed outdoor entry points without concern about temperature-related deformation or corrosion of the mounting structure.
Defined Dimensions for Rough-In Planning
With product dimensions of 373 mm x 143 mm x 67.5 mm, installers can plan the wall cavity accurately before the door station arrives on site. The packaging dimensions of 413 mm x 182 mm x 104 mm also assist with freight and storage planning on larger projects.
Best For
- New Construction Entry Points: Wall cavities can be cut to the confirmed bracket dimensions during the build phase, allowing the VTO7541G or VTO7521G to be installed flush with the finished wall surface.
- Commercial and Multi-Tenant Buildings: Outdoor entry facades on offices, apartment complexes, and commercial premises where a recessed door station finish is specified by the builder or architect.
- Renovation Projects Using VTO7541G or VTO7521G: Where an existing surface-mount installation is being replaced or upgraded to a flush-mount configuration using either of the two compatible Dahua door station models.
Why Choose the DHI-VTM121
The DHI-VTM121 is not a universal bracket – it is manufactured specifically for the DHI-VTO7541G and DHI-VTO7521G 8-inch face recognition door stations. This matters because these door stations have precise external dimensions, and a flush mount plate that is not purpose-built for them will result in gaps, misalignment, or inadequate structural support at the wall. At 373 mm x 143 mm x 67.5 mm, the VTM121 matches the form factor of these units and provides a defined cavity depth of 67.5 mm for the rough-in. The outdoor-rated operating range of -30°C to +70°C confirms it is appropriate for exposed installations without substitution. For integrators specifying a complete flush-mount door station installation using the VTO7541G or VTO7521G, this is the correct companion accessory. Available at Security Wholesalers, the DHI-VTM121 is the Dahua-supplied solution for projects where a surface-mount finish is not acceptable.
Buyer Decision Tips
Buyer Tip: Before ordering, confirm the wall material and available depth at the installation point. The VTM121 requires a recess depth of 67.5 mm to accommodate the bracket. For masonry or rendered walls, this cavity will need to be cut before the bracket is fitted. Also confirm you are installing either the DHI-VTO7541G or DHI-VTO7521G – this plate is not confirmed for use with other Dahua door station models and should not be substituted across the range.

Ideal Use Cases
Commercial Building Entries
Office buildings and commercial premises with finished exterior walls benefit from the flush mount configuration, keeping the VTO7541G or VTO7521G door station level with the wall surface for a professional entry point appearance.
Apartment Complex Outdoor Lobbies
Multi-tenant residential buildings often specify recessed door station installations at ground-floor entries. The VTM121 supports this configuration for the VTO7541G and VTO7521G in outdoor lobby and gate-entry environments.
New Construction Projects
With confirmed dimensions of 373 mm x 143 mm x 67.5 mm, builders and electricians can prepare the wall rough-in during the construction phase, ensuring the door station is recessed correctly once the fit-out stage begins.
Exposed Outdoor Gate Columns
The confirmed outdoor operating range of -30°C to +70°C makes the VTM121 suitable for installation in masonry gate columns or brick piers at driveway entries, where temperature variation is a real factor across Australian seasons.
Choosing the Right Model
- Choose this model if: You are installing a DHI-VTO7541G or DHI-VTO7521G door station and require a flush, recessed finish at an outdoor wall entry point. The VTM121 is the Dahua-supplied bracket for these specific models and provides a cavity depth of 67.5 mm.
- Choose a different model if: You are installing a different Dahua door station model – this plate is confirmed only for the VTO7541G and VTO7521G and should not be assumed to fit other door station units in the Dahua range. If a surface-mount installation is acceptable, a flush mount plate is not required.
FAQs
- Which Dahua door stations is the DHI-VTM121 compatible with?
The VTM121 is confirmed for use with the DHI-VTO7541G and DHI-VTO7521G 8-inch face recognition outdoor door stations. It is not confirmed for use with other Dahua door station models, and installers should not assume cross-compatibility within the broader VTO range.
- What wall cavity depth does the VTM121 require?
The bracket has a depth of 67.5 mm, so the wall cavity needs to accommodate at least this depth. For masonry, concrete, or rendered walls, the recess should be cut to suit these dimensions before the bracket is fitted. Confirm available wall depth before ordering.
- Is the DHI-VTM121 suitable for outdoor installation?
Yes. The VTM121 is confirmed for outdoor use with an operating temperature range of -30°C to +70°C and operating humidity between 10% RH and 90% RH. It is designed for use at outdoor entry points including gate columns, building facades, and external lobby walls.
- Does the VTM121 include any electronics, cabling, or fixings?
The DHI-VTM121 is a mechanical mounting bracket only. It does not include any electronic components, power supply, cabling, or the door station itself. It is an installation accessory to achieve a flush-mount finish when fitting the VTO7541G or VTO7521G.
- Where can I purchase the DHI-VTM121 in Australia?
The DHI-VTM121 is part of the Security Wholesalers range and is available to trade customers and installers. It is best ordered alongside the compatible door station to ensure both items arrive together for the installation. Check the product listing for current stock availability.
