Brand: Univivi
Features: 850nm infrared beam, 90-degree wide angle without hotspots; rugged IP67 waterproof housing with heavy-duty aluminum frame. Eight high-power LEDs provide strong night illumination while keeping the surface temperature cooler, suitable for both indoor and outdoor security installations.
Univivi IR Illuminator 10 LED
Brand: Univivi
Features: Automatic dusk-to-dawn operation with photocell sensor; 850nm infrared illumination invisible to the naked eye with a red glow. 10 high-power LEDs provide a wide 90-degree beam; full-size heat sink and robust housing enable reliable outdoor performance and cooler operation for longer lifespans.
Buying Guide
Key purchase considerations help ensure the IR light you choose matches your camera setup and environment:
- Wavelength and invisibility: Most security cameras respond best to 850 nm IR light, which stays invisible to the human eye while delivering clear night vision. Ensure your camera supports this wavelength or is compatible with the chosen illuminator’s spectrum.
- Range and beam angle: Long-range models (up to 80 ft or more) benefit large perimeters, while 90° or wider angles cover broader fields of view for multiple cameras. Match range and angle to your camera placement and lens focal length (2.8/3.6/4 mm lenses are common).
- Even illumination and hotspots: Look for designs that minimize hotspot effects and diffuse IR evenly across the scene. Integrated lens design and heat management contribute to consistent night images.
- Durability and weatherproofing: Outdoor deployments require IP-rated housings (IP65, IP67 or higher) and corrosion-resistant materials. A robust heat sink keeps LEDs cooler for longer life in 24×7 operation.
- Installation and adjustability: 360-degree swivel and adjustable tilts simplify aiming. Compact forms reduce mounting space, while included power adapters ease setup.
- Auto on/off and power efficiency: Photocell sensors save energy by switching illumination on at dusk and off at dawn. This feature extends device life and reduces unnecessary light emission.
- Compatibility and mounting options: Confirm mounting brackets and cable lengths align with your camera model and enclosure. Some units ship with adapters for quick installation.
- Maintenance considerations: Look for models with easily replaceable LEDs or modular components, so maintenance costs stay reasonable over time.
When choosing, balance the need for distance, coverage area, environmental exposure, and budget. The products above provide a range of options—from compact, long-range units to broad-angle, waterproof illuminators—so you can tailor your security system to your site’s unique requirements.
