850nm vs 940nm: Infrared Light Comparison
When choosing a hunting camera, night vision capability is a crucial factor. Most trail cameras use infrared (IR) LED technology for night-time recording, and the two most common IR wavelengths are 850nm and 940nm. Understanding their differences can help you make an informed decision based on your hunting or wildlife monitoring needs.
What is Infrared (IR) Light in Hunting Cameras?
Infrared light is a part of the electromagnetic spectrum that is invisible to the human eye but can be detected by night vision cameras. Hunting cameras use IR LEDs to illuminate the area at night, allowing for clear images and videos even in complete darkness. However, the choice between 850nm and 940nm IR LEDs affects image clarity, detection range, and stealth.
850nm vs 940nm: Key Differences
1. Visibility
- 850nm IR Light: Emits a faint red glow from the LED when activated. This light is barely noticeable but can be seen if directly observed in a dark environment.
- 940nm IR Light: Completely invisible to the human eye and animals, making it ideal for stealth applications.
2. Night Vision Range
- 850nm IR LEDs provide a longer illumination range, typically 15-20 meters or more.
- 940nm IR LEDs have a shorter range, usually around 10-15 meters due to their lower brightness.
3. Image & Video Quality
- 850nm delivers brighter and clearer night vision images, making it ideal for capturing high-quality footage.
- 940nm results in darker images since the emitted infrared light is weaker, but it provides better concealment.
4. Stealth & Animal Disturbance
- 850nm IR cameras may slightly startle some animals, especially those sensitive to light.
- 940nm IR cameras are fully invisible, ensuring maximum stealth—perfect for monitoring shy wildlife or security surveillance.
Which Infrared Light is Better for Hunting Cameras?
Choosing between 850nm and 940nm IR light depends on your specific needs:
- Choose 850nm if: You need longer night vision range and don’t mind a faint red glow. Ideal for general wildlife observation and hunting.
- Choose 940nm if: You need stealth and complete invisibility, even though the night vision range is shorter. Best for security monitoring and capturing shy animals.
