940nm vs 850nm Infrared: Which Is Better for a Trail Camera?

Nighttime is an important period for wildlife activity. That is why infrared night vision is an essential feature of many trail cameras. The two common infrared wavelengths are 850nm and 940nm. But what is the difference, and which one should you choose?

1. 850nm Infrared Night Vision

850nm infrared LEDs generally provide stronger illumination, helping a wildlife camera capture bright images in low-light conditions. However, the LEDs may produce a faint red glow when operating, which can be noticeable when viewed from nearby.

2. 940nm No-Glow Infrared

940nm infrared LEDs are commonly known as No-Glow infrared. Unlike 850nm LEDs, they produce almost no visible red glow during nighttime recording. This makes them a suitable choice for discreet wildlife monitoring, especially when observing deer, foxes, hedgehogs, and other nocturnal animals.

3. 850nm vs 940nm: Key Differences

Both technologies have their advantages:

• 850nm: Generally offers stronger infrared illumination but may produce a faint red glow.

• 940nm: Provides more discreet night vision with almost no visible red light.

Actual night vision distance and image brightness also depend on LED power, camera sensors, lens quality, and environmental conditions.

4. Why Choose a 940nm Trail Camera?

If you want to monitor wildlife at night without noticeable red light, a 940nm No-Glow trail camera is worth considering.

BLAZEVIDEO models such as the A106W, T306, and T326 use 940nm No-Glow infrared technology, making them suitable for nighttime wildlife observation in forests, gardens, and other outdoor areas.

Final Thoughts

When choosing a trail camera, consider more than just infrared wavelength. Night vision range, image quality, and your monitoring environment all play an important role.
