Advanced Facilities Efficient ProductionWhat IR LED Solutions Can Eliminate Overexposure for Security Monitoring Sensors?
Enable sharp night vision in CCTV, bullet cameras, PTZ surveillance devices and industrial monitoring sensors with our high-performance 850nm and 940nm IR LEDs. Strictly controlled tight wavelength bins deliver consistent infrared spectrum matching CCD/CMOS image sensors, while steady luminous output and slow light decay ensure round-the-clock stable 24/7 surveillance reliability. Available in red-glow 850nm long-range models and fully invisible 940nm covert variants, our IR LED arrays adopt thermoelectric separation heat dissipation and silicone encapsulation to avoid overheating sensor noise, supporting IP66 outdoor camera systems with clear, balanced low-light imaging without overexposure or dark corners.
Key questions
1. Which security sensors are compatible with 850nm and 940nm IR LEDs?
Answer: 850nm is suitable for general ordinary CCD/CMOS, for long-distance outdoor surveillance; 940nm needs to be paired with high-sensitivity low-light sensor, used for covert surveillance without red flare.
2. Why do the edges of the infrared camera's night images appear black?
Answer: The emission angle of the IR LED does not match the field of view angle of the lens. A corresponding angle IR light bulb needs to be selected to ensure that the light beam covers the complete imaging area of the sensor.
3. Which IR LED is more suitable for indoor surveillance?
Answer: For home and care scenarios, 940nm IR LED without red flare is preferred, paired with low-light CMOS sensor, with no red light.
4. How to combine IR LED and sensors for outdoor long-distance security surveillance?
Answer: Select the third-generation 850nm dot matrix IR array, paired with a 3MP or higher large target area CMOS sensor, and a narrow-angle lens to enhance the night vision effect at 50 meters.
Security & Sensors IR LED Technology
Precise Wavelength Matching Tech
Our 850nm & 940nm IR LEDs feature tight wavelength bins matching CMOS/CCD sensors for CCTV surveillance. Stable infrared spectrum eliminates blurry night footage, ideal for outdoor perimeter cameras and indoor monitoring sensors to enhance low-light imaging performance.

With ceramic brackets and copper substrates, this structure lowers thermal resistance and slows light decay. Silicone packaging ensures stable 24/7 operation from -40℃ to 85℃, reducing thermal noise on sensors for waterproof security camera modules.
Adjustable Secondary Optics Focusing Tech
Tunable 10°-120° beam angles fit various camera lenses to avoid overexposure and dark corners. 850nm fog-penetrating and invisible 940nm IR LEDs suit road security and covert human detection sensors with 95% high light utilization.
Key Compatibility Tips for Security & Sensors IR LEDs
Optical Parameter Matching
Match 850nm long-range or 940nm invisible IR wavelength to CCD/CMOS sensor spectrum. Adjust luminous flux: low flux for 10–30m indoor use, high flux for 30–50m outdoor monitoring to avoid overexposure or dim images.
Beam Angle Matching
Align IR LED beam angle with camera lens field of view. Accurate matching realizes even infrared coverage, removing central overexposure and dark frame edges for consistent night vision sensor output.
