Product SKU: T90D40
Product Overview
For perimeter and large-area installations where a camera’s built-in IR falls short after dark, the AXIS T90D40 IR LED Illuminator (01214-001) provides a dedicated source of 850 nm infrared light with an effective range of up to 400 m. Designed as a standalone lighting accessory for use alongside compatible Axis network cameras, it fills the gap between what a camera’s onboard IR can achieve and what demanding outdoor scenes actually require at night. Supplied with multiple interchangeable diverging lenses, the T90D40 lets installers tune the beam angle to match the camera’s field of view, reducing wasted illumination at scene edges. It supports wall, ceiling, and pole mounting, making it adaptable across a wide range of site layouts including fence lines, loading areas, and open yards. Built for outdoor conditions, it is suited to commercial, industrial, and infrastructure installations where consistent low-light visibility across long distances is a requirement.
Key Capabilities
850 nm Long-Range IR Illumination
Operating at 850 nm, the T90D40 delivers invisible infrared light across distances of up to 400 m. This wavelength is optimised for monochrome night-time capture on compatible Axis cameras, extending usable scene coverage well beyond what most built-in IR can achieve.
Interchangeable Diverging Lenses
The unit ships with multiple diverging lenses that snap in to alter the beam spread. Installers can select the angle that best matches the connected camera’s field of view, preventing hotspots in the foreground and ensuring the IR output tracks the actual scene being monitored.
Flexible Mounting for Diverse Site Layouts
The T90D40 supports wall, ceiling, and pole mounting. This flexibility means the illuminator can be positioned independently from the camera where needed, allowing installers to optimise the lighting angle on fence lines, yard entrances, or open outdoor areas without being constrained to the camera’s own mount point.
Outdoor-Ready Construction
The T90D40 is built for permanent outdoor installation, with a robust housing engineered to withstand environmental exposure. This makes it suitable for unprotected mounting locations such as perimeter fences, loading dock walls, and external building facades where weather resistance is a baseline requirement.
Targeted Supplemental Illumination
Rather than flooding an entire area with broad ambient light, the T90D40 directs concentrated IR output at the specific zone a camera is monitoring. This targeted approach reduces IR bleed into adjacent areas and helps cameras produce more uniform image quality across the scene depth.
Best For
- Long Perimeter Fence Lines: The 400 m IR range makes it suitable for covering extended fence lines where a single well-positioned illuminator can replace multiple shorter-range units.
- Open Yards and Car Parks: Installations covering large flat surfaces at night benefit from the T90D40’s ability to project IR across wide distances while adjustable lenses control the beam spread to match wide-angle camera views.
- Camera Upgrades Where Built-In IR Is Insufficient: When an existing Axis camera covers a critical scene but its onboard IR does not reach far enough, the T90D40 adds dedicated external lighting without requiring the camera itself to be replaced.
- Industrial and Infrastructure Sites: Facilities with limited ambient light, such as storage yards, substations, and construction perimeters, benefit from the T90D40’s focused output and durable outdoor housing.
Why Choose the AXIS T90D40 IR LED Illuminator
The AXIS T90D40 addresses a specific gap that arises in professional perimeter installations: the distance between what a camera’s built-in IR provides and what the scene actually demands. With an effective IR range of up to 400 m at 850 nm, this illuminator is designed for serious long-range outdoor applications rather than simple close-range fill lighting. The supplied interchangeable lenses mean it can be calibrated to the exact coverage angle of the camera it supports, avoiding the overexposure and hotspotting that occur when a fixed-beam illuminator is paired with a wide-angle lens. Its independent mounting capability allows installers to separate the light source from the camera position, which is a practical advantage on industrial sites where a single optimal mounting point rarely satisfies both requirements simultaneously. Available through Security Wholesalers as part of the Axis accessories range, the T90D40 is built to the same construction standards expected of professional-grade Axis products for permanent outdoor deployment.
Buyer Decision Tips
Buyer Tip 1 – Match the Lens to Your Camera’s Field of View: The T90D40 ships with multiple diverging lenses, but selecting the right one before installation matters. Measure or confirm your camera’s horizontal field of view at the intended distance and choose the lens that most closely matches it. A beam that is too narrow will leave the scene edges dark; a beam that is too wide will reduce the effective illuminated distance and create an uneven exposure across the frame.
Buyer Tip 2 – Mount Position Affects Range Performance: The 400 m IR range figure applies under optimal conditions, including a clear line of sight and appropriate mounting height. In practice, lower mounting angles, obstructions, or reflective surfaces can reduce effective range. For perimeter applications, mounting the T90D40 at height on a pole rather than at ground level will typically improve the usable illumination distance and reduce interference from foreground objects close to the unit.

Ideal Use Cases
Perimeter Fence Monitoring
The T90D40’s 400 m IR range makes it well suited to illuminating extended fence lines at night. A single unit can cover a substantial run when positioned at the correct height and angle, reducing the number of individual lighting points required along a secured boundary.
Car Parks and Open Yards
Large flat surfaces with no ambient lighting after hours benefit from the T90D40’s ability to throw IR across wide distances. The interchangeable lenses allow the beam width to be matched to the wide fields of view typically used in car park and open-area cameras.
Loading Docks and Industrial Yards
Industrial sites with limited infrastructure lighting rely on dedicated IR to maintain camera visibility after dark. The T90D40’s outdoor-rated housing and independent mounting options allow it to be positioned at the optimal angle for dock entrances, storage areas, and vehicle movement zones.
Building Perimeters and Entry Points
Commercial buildings where camera coverage extends well beyond the building’s facade require supplemental IR to maintain usable image quality at distance. The T90D40 can be pole or wall mounted to direct 850 nm illumination toward entry roads, gates, and approach paths that fall outside the camera’s built-in IR reach.
Choosing the Right Model
- Choose this model if: Your installation requires supplemental IR illumination across distances up to 400 m, particularly on perimeter fence lines, open yards, or industrial sites where the camera’s built-in IR is insufficient for the required coverage depth.
- Choose a different model if: Your scene requires illumination distances shorter than what this unit is designed for and a more compact, lower-output illuminator would suit the budget and site scale better. Similarly, if visible white-light deterrence or full-colour night illumination is the primary goal rather than invisible IR supplementation, a different lighting accessory type would be more appropriate.
FAQs
- What is the difference between using the T90D40 and relying on a camera’s built-in IR?
Built-in IR LEDs in most cameras are optimised for scenes within 30 to 80 m and are constrained by the camera’s power budget and housing size. The T90D40 is a dedicated external illuminator with a confirmed range of up to 400 m, making it the appropriate choice when the monitored scene extends well beyond what onboard IR can realistically cover, such as long driveways, yard approaches, or open perimeters. - Why does the wavelength being 850 nm matter for camera compatibility?
850 nm is within the near-infrared spectrum that most CMOS and CCD image sensors in Axis network cameras are sensitive to. It produces strong scene illumination that is invisible to the human eye under normal conditions, allowing cameras to capture clear monochrome images at night without alerting subjects to the presence of active lighting. Confirm that the paired camera supports 850 nm sensitivity before installation. - Can I mount the T90D40 separately from the camera?
Yes. The T90D40 supports wall, ceiling, and pole mounting independently of the camera it is supplementing. This is a practical advantage for perimeter and industrial applications where the camera’s mounting position does not always provide the best angle for directing IR illumination across the intended scene. Independent positioning can significantly improve coverage uniformity. - How do the interchangeable lenses affect the 400 m range figure?
The effective range is influenced by the selected lens. A narrower beam concentrates IR output over a longer distance, maximising reach toward the 400 m figure. A wider-angle lens spreads the same IR energy across a broader area, reducing the effective distance but increasing coverage width. The right lens choice is a trade-off between reach and spread, and should be matched to both the camera’s field of view and the geometry of the scene. - Is the T90D40 suitable for permanent outdoor installation in Australian conditions?
The T90D40 is constructed for outdoor use, with a housing engineered to withstand environmental exposure. It is available through Security Wholesalers as part of the Axis accessories range for professional installation in commercial and industrial outdoor environments. For specific ingress protection ratings and operating temperature ranges, refer to the official Axis datasheet linked in the Additional Information section below. - Does the T90D40 require a separate power supply, and how is it connected to the camera?
The T90D40 is a standalone illuminator that operates independently of the camera’s power circuit. It requires its own power connection rather than drawing power through the camera. Consult the product datasheet for confirmed power input specifications and cabling requirements before planning the installation, particularly for sites where power runs to the illuminator mounting position will need to be factored into the cable plan.
