Univivi 20 LEDs Infrared Illuminator
Univivi’s upgraded IR floodlight delivers a strong 850nm beam with a 90-degree wide angle, designed for CCTV night vision without visible glow. The device uses a photocell sensor to automatically turn on at dusk and off at dawn, conserving energy and extending lifespan. A thick aluminum housing and heat sink keep surface temperatures under 120 ℉ even with continuous operation, making it suitable for outdoor cameras as well as indoor installations. This unit is IP67 waterproof for weather resistance.
Key features include auto on/off control, an invisible IR spectrum that still provides red glow when illuminated, and a robust build intended for long-term reliability in varied environments.
Tendelux 80ft IR Illuminator
This Tendelux model emphasizes a long-range, even illumination footprint for cameras with longer lenses. It features 4 x 1-watt 850nm LEDs and a 90-degree flood pattern, enabling better situational visibility at the edges of a scene. An IR band-pass filter helps minimize hot spots and prevent foreground overexposure, giving a more uniform night image. It ships with a power adapter for straightforward installation.
The design suits cameras with lenses in the 2.8–4 mm range and focuses on even lighting across the field of view, reducing the common problem of bright hotspots in security footage.
Tendelux DI20 IR Illuminator
DI20 offers a compact yet powerful infrared flood light designed for long-range needs. It’s half the size of larger Tendelux models while delivering higher illumination for clear night footage. The product emphasizes even illumination with a tailored lens that reduces hot spots. An adjustable mounting system—360-degree swivel with a 90-degree tilt—facilitates precise alignment. The unit uses premium aluminum construction for durability against sun exposure and weather.
Ideal for tight installation spaces where space and beam quality must be balanced, this model emphasizes stable performance and flexible mounting options.
Tendelux DI20B IR Illuminator
The black variant of the DI20 series provides the same long-range performance with a more discreet appearance. This model maintains even illumination and avoids hotspot effects to ensure consistent camera night vision across its field of view. It features a 360-degree swivel and 90-degree tilt bracket, making horizontal and vertical aiming straightforward. The aluminum body ensures durability in outdoor environments where sun exposure is a concern.
For cameras mounted on walls or corners, the DI20B offers enhanced concealment while preserving the benefits of Tendelux’s broad flood pattern.
Univivi IR Illuminator 10 LED
Univivi’s 10-LED IR illuminator focuses on a compact footprint without sacrificing essential night-vision capability. It uses a photocell sensor for automatic on/off, delivering energy efficiency and long-term reliability. The product adopts a full-size heat sink to keep operating temperatures below 120 ℉ during continuous use, helping maintain performance across day-night cycles. A 90-degree wide-angle distribution ensures broad coverage for typical CCTV installations.
The smaller form factor is suitable for tighter camera deployments where a larger IR light would be impractical.
DMetric IR Illuminator
The DMetric IR illuminator brings automatic operation via a CDS light sensor, switching on in low ambient light and off when daylight returns. It uses a waterproof IP65 housing and a robust aluminum build for outdoor use. The 850nm infrared beam is invisible to the naked eye while still producing effective night vision. A 60-degree wide angle balances dispersion with beam intensity for mid-sized surveillance zones.
This option is well-suited for exterior cameras facing porches, yards, or driveways where weather resistance and consistent night coverage matter most.
Buying Guide: Key Considerations For Infrared Security Lighting
- Range and beam angle: Longer range helps distant cameras, while a wider angle reduces hotspots. Match the beam to the camera’s lens field of view.
- IR wavelength: Most security cameras respond to 850nm or 940nm. 850nm offers brighter illumination but may be more visible; 940nm is almost invisible but can provide softer night imagery depending on the camera sensor.
- Power and heat management: Look for units with heat sinks and robust housings to maintain performance during extended use and in outdoor conditions.
- Weather resistance: IP ratings (e.g., IP65, IP67) indicate weather sealing. Outdoor installations benefit from higher protection against rain and dust.
- Auto on/off features: Photocell sensors conserve energy by turning lights on at dusk and off at dawn, reducing wear and power usage.
- Mounting flexibility: Swivel and tilt capabilities simplify aiming. Check for compatibility with your camera’s mounting options and enclosure.
- Size and integration: Compact units can fit tight spaces; consider whether the IR unit will be visible in the frame and if a discreet appearance is preferred.
- Durability and materials: Aluminum housings and weather-rated seals extend service life in outdoor deployments.
- Compatibility: Ensure the IR illuminator operates at the same voltage as your camera system (commonly 12V or 110–220V AC) and pairs well with your camera’s night vision capabilities.
When selecting an IR illuminator, assess your camera lens, scene layout, and required nighttime coverage. For longer driveways or wide entrances, opt for models with higher range and well-distributed beams. For tight setups, prefer compact designs with flexible mounting. Consider whether you need automatic sensing and weatherproof protection to maintain consistent performance across seasons.
