Product SKU: DHI-ARA34E
Product Overview
Key Capabilities
±40° Horizontal Adjustment
The bracket allows the attached detector to rotate up to 40° in either horizontal direction. This provides an 80° total adjustment range for refining the detector’s aim after the wall-mounting position has been selected.
Purpose-Built Detector Compatibility
The ARA34E is designed specifically for Dahua ARD2251E-series detectors. Using the purpose-built bracket provides a more predictable mechanical fit than adapting a generic alarm-sensor mount with unconfirmed attachment points.
Compact Wall-Mounted Design
At 94 × 73.4 × 55mm, the bracket adds directional adjustment without requiring a large mounting structure. Its compact size suits wall positions where clearance beside doors, windows or surrounding fittings is limited.
Aluminium-Alloy Construction
The silvery aluminium-alloy body provides a rigid support point for the compatible detector while keeping the bracket’s net weight to 140g. It requires no power, batteries, programming or alarm-system configuration.
Best For
- Angled Wall Positions: Directs a compatible detector towards the required area when the available wall faces another direction.
- Doors and Entry Areas: Supports more accurate horizontal positioning beside doorways and controlled access points.
- Window Approaches: Helps aim the detector across the intended approach rather than directly away from it.
- Corridors and Passageways: Provides additional positioning flexibility where the detector must face along a narrow route.
- ARD2251E-Series Installations: Suits new installations or bracket replacements where the full compatible detector model has been confirmed.
Why Choose the DHI-ARA34E
The DHI-ARA34E is useful when the best detector location and the best detector direction are not the same. A standard fixed installation can leave the sensor facing squarely away from the area it needs to cover, particularly beside door frames, window reveals or intersecting corridors. The bracket’s ±40° horizontal adjustment allows the installer to retain the preferred wall position while refining the detector’s direction. Its aluminium-alloy construction also provides a purpose-built alternative to improvised or generic mounts with uncertain compatibility. Available through Security Wholesalers, the ARA34E should be selected only for confirmed ARD2251E-series detectors. It does not provide a stated vertical tilt range and should not be treated as a universal detector bracket.
Buyer Decision Tips
Adjustment Tip: The specified movement is horizontal only. Do not assume that the ARA34E provides vertical tilt when planning the detector height or coverage direction.
Environmental Tip: The bracket has basic protection and a basic anti-corrosion level, but no IP weather-resistance rating is listed. Confirm that the complete detector installation suits the intended environment.

Ideal Use Cases
Doorway Approaches
Aim a compatible detector towards the path used by people approaching the entrance.
Window Areas
Refine the detector direction when the available wall is positioned beside the intended coverage area.
Hallway Junctions
Turn the detector towards one corridor or passage where a square wall position would face another direction.
Corner-Adjacent Walls
Add horizontal adjustment where a detector needs to look across an adjoining room or opening.
Replacement Bracket Projects
Replace a missing or damaged mount after confirming the installed detector belongs to the ARD2251E series.
Choosing the Right Model
- Choose this bracket if: A compatible ARD2251E-series detector requires up to ±40° of horizontal aiming.
- Use the detector’s fixed mount if: The available wall already faces the required coverage direction.
- Choose another bracket if: Vertical tilt or compatibility with a different detector series is required.
- Check the installation height if: The planned wall position is outside the specified 0.8–1.3m range.
- Confirm environmental suitability if: The bracket and detector will be exposed to rain, moisture or corrosive conditions.
FAQs
- What is the Dahua DHI-ARA34E used for?
The DHI-ARA34E is a wall-mount bracket for compatible Dahua ARD2251E-series detectors. It allows the installed detector to be turned horizontally after mounting, helping the installer aim it towards the intended coverage area. The bracket is a passive mechanical accessory and does not include the detector, alarm hub, batteries, wiring or electronic alarm functions. - Which detectors are compatible with the DHI-ARA34E?
The DHI-ARA34E is specified only for the Dahua ARD2251E series. It should not be assumed to fit another Dahua detector or a third-party alarm sensor simply because the housing appears similar. Before ordering, confirm the complete detector model and its mounting interface. The bracket does not change the detector’s detection technology, wireless compatibility or operating features. - How much horizontal adjustment does the ARA34E provide?
The bracket provides horizontal rotation of ±40°, giving an 80° total adjustment range from one side to the other. This allows the detector direction to be refined after the bracket is attached to the wall. The listed adjustment is horizontal only, so buyers should not assume that the bracket also provides a specified vertical tilt range. - What installation height is specified for this detector bracket?
The listed installation height is 0.8 metres to 1.3 metres. The final position should also follow the installation requirements of the compatible ARD2251E-series detector and the intended detection area. Mounting the bracket outside the specified height range can affect how the detector is aimed, so the wall position should be planned before holes are drilled. - Can the DHI-ARA34E be installed outdoors?
The bracket has basic protection and a basic anti-corrosion level, but no IP weather-resistance rating is listed. It operates from -25°C to +60°C at 10%–90% relative humidity. For exposed or moisture-prone locations, confirm that the complete detector installation is suitable for the environment rather than relying on the aluminium bracket alone for weather protection. - What material, colour and dimensions does the ARA34E have?
The DHI-ARA34E is made from aluminium alloy and has a silvery finish. Its dimensions are 94.0 × 73.4 × 55.0mm. The bracket weighs 140g net and 230g packaged. These measurements help when checking wall clearance, detector projection and nearby obstructions before installation, particularly in narrow corridors or beside door and window frames. - Does the DHI-ARA34E include the ARD2251E detector?
No. The DHI-ARA34E is the adjustable aluminium mounting bracket only. A compatible ARD2251E-series detector must be purchased separately unless it is explicitly included in another package. When ordering through Security Wholesalers, provide the full detector model so compatibility can be checked before the bracket is installed. - When should I choose this bracket instead of the detector’s standard mounting position?
Choose the DHI-ARA34E when a compatible ARD2251E-series detector needs horizontal aiming after wall mounting. It is useful where the ideal detection direction does not align squarely with the available wall surface. A standard fixed mounting position may be sufficient when the detector can already face the required area without adjustment, reducing the number of installation components.
