Klgeivb 850nM IR Illuminator For Night Vision
Designed to boost CCTV night vision, this 850nm illuminator supports 850nm, 940nm, and 980nm IR capable cameras. It increases brightness and range for security cameras with night vision features. The unit uses three high-power 3W LEDs, delivering a practical reach up to about 20 feet in real-world conditions and a maximum range around 30 feet in open spaces. A 45° diffuser helps provide a uniform light distribution to minimize hotspots and shadows, contributing to clearer nighttime footage.
Klgeivb E26 940nM/850nM Infrared LED Bulb
This 180° wide-angle infrared bulb supports both 850nm and the invisible 940nm wavelengths, making it suitable for cameras sensitive to either range. It is advertised to help provide a night vision reach of roughly 15-20 square meters with nine high-power IR LEDs. The broad 180° beam ensures wide coverage, useful for monitoring larger rooms or open spaces. The design is compatible with E26/E27 sockets, offering straightforward installation on many standard fixtures.
Univivi 10 LED IR Illuminator
Univivi’s IR flood light is built with a photocell sensor, enabling auto on at dusk and off at dawn for energy efficiency. It operates at 850nm and features an upgraded full-size heat sink to keep surface temperatures under 120 ℉ even with continuous operation. The unit provides a 90-degree wide beam, utilizing 10 high-power LEDs for broad, even illumination without hot spots. It’s designed for both outdoor and indoor security camera setups, contributing to consistent night-vision performance around the clock.
Klgeivb E26 180° Infrared LED Bulb (850nM Visible)
This variant mirrors the earlier 180° design but emphasizes visibility at 850nm with optional 940nm sensing. It claims to extend night-vision coverage to roughly 15-20 square meters using nine high-power IR LEDs. The broad 180° distribution helps illuminate larger areas, making it a practical fit for security setups requiring wide-angle coverage in living rooms, garages, or hallways while maintaining compatibility with a range of IR-sensitive cameras.
GODIYMODULES 850nm 48pcs IR Illuminator
This board-style IR illuminator uses 48 infrared LEDs at 850nm for robust, compact night-vision lighting. It’s designed for CCTV camera housings with roughly a 50mm diameter shell, providing a focused, fence-posted light source that helps improve image clarity in low-light conditions. The module approach is suitable for custom installations or camera enclosures where a discrete, low-profile IR solution is preferred.
Buying Guide
- Wavelength compatibility: Most CCTV cameras respond to 850nm or 940nm IR. If your camera is sensitive to both, consider options advertising dual-wavelength support to maximize compatibility and brightness.
- Beam angle and coverage: Narrow beams concentrate light for longer reach, while wide-angle beams illuminate larger areas. Choose based on room size and camera placement.
- Power and LED count: More LEDs generally mean brighter illumination but higher power consumption and heat. Balance brightness with heat management for 24×7 operation.
- Infrared visibility vs. detectability: IR light is invisible to the naked eye but enhances camera sensitivity. If you need discreet lighting, select 850nm or 940nm options with diffusers to minimize hotspots.
- Mounting and form factor: Consider socket type (E26/E27), enclosure, and compatibility with existing housings or fixtures. Board-style modules offer compact integration, while bulb-style units are straightforward to replace.
- Weather and environment: Outdoor installations benefit from weatherproof designs and robust heat dissipation. Indoor options emphasize diffuse lighting and easy placement.
- Power protection: Look for devices with built-in heat sinks or thermal management to extend lifespan in continuous operation.
- Installation considerations: Verify camera compatibility, ensure correct mounting height, and avoid glare or reflections that could degrade footage.
In evaluating options, consider the specific surveillance scenario: room size, whether you need auto dusk-to-dawn operation, whether you require a broad 180° or narrower beam, and how discreet the IR source should be. The selections above cover a range of common use cases, from simple bedside cameras to larger perimeter surveillance setups.
