Which Dahua door station is compatible with the VTM57R?

Dahua officially lists the DHI-VTO6521K and VTO6521K as the applicable product models. The mounting points, internal clearances and front opening are designed for that station, so the VTM57R should not be treated as a universal enclosure for other Dahua intercoms. Confirm the exact label and hardware revision of the door station before ordering or drilling the wall.

What material is the rain cover box made from?

The enclosure is manufactured from AL5052 aluminium and finished with powder spraying. Dahua highlights its light material and anti-rust design, making it more suitable for exposed entrance installations than an untreated steel enclosure. Anti-rust construction does not mean the product is immune to corrosion, especially in coastal, industrial or chemically aggressive environments where inspection and maintenance remain important.

Is the VTM57R waterproof?

Dahua specifies the VTM57R for outdoor operation and describes it as a surface-mounted box with rain cover, but the official specification does not publish a standalone IP weatherproof rating for the accessory. Weather resistance depends on correct wall preparation, cable entry, drainage, sealant, fasteners and installation of the compatible door station. It should not be described as a sealed waterproof junction enclosure.

What are the dimensions of the VTM57R?

The enclosure measures 410.4mm high, 147.4mm wide and 107mm deep. Dahua lists a net weight of 0.95kg and packaged dimensions of 464 × 183 × 164mm. Check that the wall has sufficient clear area for the full height and hood projection, while also allowing comfortable visitor access, camera framing and safe cable routing behind the door station.

What temperature range is the rain cover designed for?

Dahua specifies outdoor operation from –30°C to +60°C. This rating applies to the mounting accessory itself and does not override the environmental limits of the installed door station, cables, lock equipment or power components. Site suitability should also consider direct sun, salt exposure, condensation, wind-driven rain and thermal movement between the aluminium enclosure and the mounting surface.

Does the VTM57R include the VTO6521K door station?

No. The VTM57R is a mounting accessory only. The compatible VTO6521K door station, network or two-wire equipment, power supply, electric lock, exit button, door contact, cards, cabling and installation services must be ordered separately unless they are explicitly included in another package. Always check the seller’s listed carton contents before assuming that intercom electronics or door hardware are supplied.

What should I confirm before ordering this surface-mount box?

Confirm the exact VTO6521K model, wall material, cable entry point, mounting height, weather exposure and available installation area. Plan suitable anchors, sealing and drainage rather than relying only on the rain hood. Security Wholesalers can assist with checking the enclosure against the selected Dahua door station and the wider intercom, power and door-lock arrangement.

Description

Product SKU: DH-AC-VTM57R

Product Overview

The Dahua DH-AC-VTM57R VTM57R is a surface-mount aluminium enclosure with an integrated rain cover, purpose-built for the DHI-VTO6521K/VTO6521K apartment door station. Its AL5052 casing combines lightweight construction with an anti-rust design, while the silver powder-coated finish provides a clean appearance for residential and commercial entrances. The enclosure measures 410.4 × 147.4 × 107mm and allows the compatible door station to be installed on the face of a suitable wall instead of recessed into a flush box. Dahua specifies outdoor operation from –30°C to +60°C. No standalone IP rating is published, so cable entry, wall sealing, drainage, fixings and door-station installation must be completed correctly.

Key Capabilities

Surface-Mount Installation

Provides the compatible VTO6521K door station with a dedicated enclosure for installation on the face of a suitable wall rather than inside a recessed opening.

Integrated Rain Hood

The projecting upper cover helps shelter the installed door station from direct rain and runoff at exposed residential and commercial entrances.

AL5052 Aluminium Construction

Lightweight aluminium construction supports outdoor mounting while reducing the corrosion risk associated with untreated ferrous metal.

Powder-Coated Finish

The silver powder-sprayed surface provides a clean architectural finish and an additional protective layer for normal outdoor applications.

Anti-Rust Design

Dahua specifically identifies an anti-rust design for use at entrances where moisture and changing weather conditions must be considered.

Purpose-Built Compatibility

The dimensions, mounting format and opening are designed for the Dahua DHI-VTO6521K/VTO6521K apartment door station.

Best For

VTO6521K Installations: Provides the official surface-mount rain-cover accessory for the compatible apartment door station.
Walls That Cannot Be Recessed: Avoids the large cavity required by a flush-mount enclosure.
Partially Exposed Entrances: The upper hood provides added shelter from direct rain and water runoff.
Retrofit Intercom Projects: Supports installation on suitable existing walls where a new apartment entrance station is being added.
Professional Entrance Finishes: Powder-coated silver aluminium provides a coordinated, purpose-built mounting solution.

Why Choose the VTM57R

The VTM57R combines the surface box and rain hood required for a neat VTO6521K installation in one purpose-built accessory. Its AL5052 aluminium casing is lighter than many steel alternatives and Dahua specifically identifies an anti-rust design for outdoor applications. The 107mm total projection provides enclosure depth and weather shelter while avoiding a deep wall recess, making the box particularly useful for concrete, masonry and retrofit sites. Supplied by Security Wholesalers, this accessory should be selected only after confirming the exact door-station model, wall area, cable pathway, mounting height and environmental sealing requirements.

Buyer Decision Tips

Compatibility Tip: Dahua lists the DHI-VTO6521K/VTO6521K as the applicable model. Do not assume compatibility with another apartment or villa door station based only on similar external dimensions.

Weather-Sealing Tip: The hood reduces direct exposure but does not create a sealed waterproof enclosure. Plan wall sealant, cable-entry protection, drainage and corrosion maintenance for the actual site.

Choosing the Right Model

Choose the VTM57R if: You are surface mounting a compatible VTO6521K and require an integrated rain hood.
Choose a flush box if: The door station must sit more closely within the wall for a lower-profile architectural finish.
Choose another enclosure if: The selected door station is not explicitly listed as compatible with the VTM57R.
Allow sufficient wall area: The complete accessory is 410.4mm high and 147.4mm wide, with a maximum projection of 107mm.
Assess harsh environments: Coastal salt, industrial chemicals and constant moisture may require additional maintenance or a different material strategy.
