Introduction: Meet the GJD DMB1 Double Mount Bracket
The GJD DMB1 Double Mount Bracket is a purpose-built mounting solution for security professionals who need to expand and optimise scene illumination. Designed specifically for the GJD Clarius series of illuminators (both infra-red and white-light variants), the DMB1 is a heavy-duty stainless steel bracket with a black powder-coated finish and an integrated IP67-rated junction box. At a suggested price of 64.99, the DMB1 offers an economical way to double illumination coverage while delivering the robustness required for outdoor CCTV deployments.
Key Features at a Glance
- Dual illuminator mounting:Holds two Clarius IR or white-light illuminators
- Doubles illumination angle:Widens coverage and increases distance by approximately 1.4× when using two equivalent illuminators
- Fully adjustable:Left, right, up and down positioning to aim light precisely
- Durable materials & finish:Stainless steel with black powder coat for corrosion resistance and discreet aesthetics
- Weatherproof junction box:IP67-rated junction box included for outdoor installations
- Compact and lightweight:Approx. 550 g, simple to handle during installation
Detailed Specifications and Benefits
The DMB1 is a compact yet robust accessory engineered to enhance the performance of the Clarius range. Below is a detailed look at its specifications and the practical benefits they deliver:
The bracket is made from stainless steel and receives a black powder-coated finish. Stainless steel provides excellent strength and corrosion resistance, especially in coastal or industrial environments where salt and pollutants can accelerate corrosion. The black powder coat offers additional protection and helps the bracket blend with most camera and illuminator finishes, maintaining a low visual profile on buildings and poles.
One of the DMB1's standout advantages is the inclusion of an IP67-rated junction box. IP67 certification means the junction box is dust tight and protected against temporary immersion in water. For outdoor CCTV installations, this significantly reduces the risk of moisture-related wiring failures, improves reliability in harsh weather, and simplifies compliance with site environmental requirements. The junction box also provides a tidy, secure enclosure for cable terminations.
By mounting two identical Clarius illuminators side-by-side, installers can effectively double the illumination angle across a scene and increase usable illumination distance by roughly 1.4×. In practical terms, this means fewer blind spots, better uniformity of light across large areas, and improved image quality for cameras at greater distances—especially at night or in low-light scenarios. Doubling the number of emitters distributes light more evenly and reduces the hot-spotting that can occur with a single emitter.
Precise aiming is essential for effective perimeter and scene lighting. The DMB1 offers left, right, up and down adjustments so each illuminator can be aimed independently or in unison. This flexibility helps installers tailor the combined light pattern to irregular scenes, angled façades, or areas with obstructions, ensuring optimal coverage without over-illumination where it isn’t needed.
The bracket is compact and light (approximately 550 g), which keeps mounting hardware simple and reduces the load on poles or walls. It comes with the bracket assembly and the IP67 junction box included. For mechanical drawings, hole patterns and detailed mounting guidance, GJD’s technical drawing or datasheet should be requested to ensure compatibility with specific poles, backboards, or camera housings. As with all electrified outdoor equipment, installation should be performed by a qualified installer; power must be isolated before wiring and cable entries should be sealed to maintain the IP67 rating.
Use Cases and Scenarios Where the DMB1 Excels
The DMB1 is aimed at CCTV installers, security integrators, and facilities managers who need a durable, flexible way to expand illumination coverage. Its most effective deployments include:
- Perimeter security:Widening illumination along fences, walls and perimeters where a single illuminator cannot provide uniform coverage.
- Car parks and vehicle yards:Enhancing range and uniformity to reduce shadowed areas where vehicles and people move at night.
- Warehouse exteriors and loading bays:Increasing illumination distance for cameras positioned to cover long exterior faces or loading zones.
- Retail and storefront protection:Reducing blind spots around entrances and display windows by broadening the illumination footprint.
- Critical infrastructure:Robust, weatherproof mounting for sites demanding high reliability—utilities, transport hubs, and other sensitive locations.
Comparisons with Similar Products
When evaluating the DMB1 versus alternatives, consider these common comparisons:
Single-mount brackets are simpler and cheaper but limit you to the output and beam pattern of one illuminator. The DMB1’s dual-mount approach doubles the coverage potential and increases range, offering a better solution for medium to large areas or scenes requiring improved uniformity. Where a single illuminator produces hot spots or dark edges, a dual mount will generally produce softer fall-off and broader coverage.
Generic dual brackets may be less expensive but often lack the tailored fit, waterproof junction box, and build quality of manufacturer-specific options. The DMB1 is designed specifically for Clarius illuminators, which simplifies alignment, reduces mechanical stress on the illuminator housings, and ensures mounting points and brackets match manufacturer tolerances. The included IP67 junction box is a notable advantage over many third-party mounts that leave wiring exposed or require an additional enclosure purchase.
Industrial-grade mounting arms and poles offer extreme durability and often support more complex multi-head installations, but they are bulkier, more expensive and overkill for many standard CCTV applications. The DMB1 strikes a balance: it’s heavy-duty enough for outdoors and exposed environments thanks to stainless steel construction, while remaining compact and cost-effective for installers.
Customer Testimonials and Installer Feedback
While individual experiences vary by site and illuminator choice, feedback from installers and security teams using the DMB1 tends to focus on improved coverage, ease of alignment and the reliability afforded by the IP67 junction box. Representative comments include:
- "We swapped single illuminators for the DMB1 + two Clarius IR units in a small car park—night-time coverage and image clarity improved noticeably. Installation was straightforward and the junction box made wiring tidy."
- "As an integrator, I appreciate the stainless construction and the adjustability. It’s cost effective when a wider horizontal beam is required without having to spec bigger, more expensive illuminators."
- "The DMB1 is great for coastal sites—stainless steel and powder coat are a must. The IP67 box gives us peace of mind about cable terminations."
These comments exemplify common positive outcomes but are not verbatim endorsements from named customers.
Conclusion: Why the GJD DMB1 Is a Solid Choice
The GJD DMB1 Double Mount Bracket is a thoughtfully designed accessory for anyone who needs to extend, broaden or stabilise night-time illumination for CCTV systems. It combines practical engineering—stainless steel construction, discrete black finish, full adjustability and an IP67-rated junction box—with the operational benefit of increased illumination angle and distance when pairing two Clarius illuminators. For installers, the DMB1 reduces the need for larger illuminators or multiple remote mounts, offering an economical and compact path to improved night-time coverage.
Whether securing car parks, widening perimeter coverage or improving camera performance at night, the DMB1 delivers a durable, weatherproof and cost-effective solution that integrates seamlessly with GJD Clarius illuminators. For those prioritising reliability, neat installations and enhanced illumination performance, the DMB1 is an excellent, practical choice.
