How to Choose the Best IR Illuminator for Night Vision

Are you still unsure which IR illuminator to get? Fret not! Below is a handy buying guide to help you make a wise purchasing decision.


One of the first factors to consider before buying an IR illuminator is the LED or IR wavelength. You must ensure that your security camera can detect this light when shooting at night.

Infrared wavelengths are measured in nanometers, or simply nm. IR illuminators usually range between 850nm and 940nm. For comparison, visible light typically has a 390nm to 700nm wavelength.

850nm and 940nm are neck and neck when it comes to performance. With that said, it is still essential to consider their differences.

For instance, an 850nm wavelength produces a faint red glow, despite the actual infrared light being invisible. Thus, it is not the best choice if you want to be completely hidden from view. On a positive note, it is more effective when illuminating far distances.

Meanwhile, a 940nm does not create any visible glow, making it entirely invisible. However, it can only illuminate short distances compared to an 850nm IR illuminator.

Choosing between the two will ultimately depend on your needs and personal preferences.

Range of Illumination

This factor simply refers to how far the device can cast light over an area. However, the range of illumination involves many variables, such as how large the subject is and how clear you can see at certain distances.

You might also want to consider the amount of light already available within a scene. Of course, the more ambient light around the area, the further the IR illuminator can see.

However, do not worry if you are shooting in pitch dark settings. Some models already offer an extended range of illumination. Thus, they can deliver bright and clear images, despite only having the stars or moon as lighting sources.

Weather Rating

Although IR illuminators can be used indoors, they are most handy when it comes to outdoor applications. And as you probably already know by now, weather conditions can often be harsh to devices.

Thus, you might want to look for an IR illuminator that is waterproof, dustproof, and weatherproof. Check the Ingress Protection (IP) rating of the product to determine how resistant it is against water and other debris.

The higher the IP rating, the more resistance it provides.

As a rule of thumb, IP6 and above ensure protection against unforgiving weather conditions.


No one wants to invest in an IR illuminator that will falter within a few months of use. That is why it is essential to consider the build of the item. Make sure it uses high-grade and top-quality materials, such as aluminum.

Besides the construction material, the weather rating can also contribute to the durability of an IR illuminator.

Power Source

All IR illuminators require direct current in order to function properly. However, you might also want to consider a model that accepts AA or CR123A lithium batteries for additional flexibility.

AA batteries usually provide about three to four hours of energy to your device. Meanwhile, CR batteries can power IR illuminators at around 3.5 hours. Both battery types can be easily replaceable, making them very convenient.

Frequently Asked Questions

Can you see IR illuminators?

IR illuminators produce infrared light that is invisible to the human eye. However, night vision devices with an IR wavelength of 850nm have a noticeable red glow when you look at them directly. So make sure to consider this factor before buying an IR illuminator.

Where do you put an IR illuminator?

It is best to place the IR illuminator as close as possible to the camera. Ensure that you align it with the camera’s line of sight to ensure you are correctly illuminating the scene. After that, screw the device tightly and then make fine adjustments based on your needs.

Do I need to protect my eyes from infrared light?

Unless you look at infrared light intensely, you probably do not need to worry about damaging your eyes. However, if you are working closely with an infrared laser, it is essential to wear safety glasses. You may also need to take appropriate protection measures to keep you safe.


That sums up our top picks for the best IR illuminator for night vision! We highly recommend every product on this list as they help you achieve brighter images in the dark.
