Boost your night surveillance instantly by pairing this illuminator with your IR‑enabled camera.

The 940nm wavelength is completely invisible to the human eye and to mobile phone cameras, making it a perfect fit for anyone who needs truly discreet infrared support. To see its effect, be sure to test it with a proper IR‑sensitive CCTV camera rather than relying on visible confirmation.

Its six infrared LEDs deliver strong supplemental light, helping security cameras perform better in areas where built‑in IR is insufficient. The unit uses a light‑sensing component that automatically activates the LEDs in darkness and shuts them off in daylight. This sensor is exclusively for detection—it's not a status indicator.

The illuminator is housed in durable aluminum with reinforced glass, offering dependable protection for outdoor or indoor installation. It operates on a 12V DC power supply, ensuring stable performance for long‑term security setups.

You can tailor the infrared coverage by selecting different beam angles. Narrower angles concentrate light for greater distance, while wider angles spread the illumination for close‑range areas. This makes the unit suitable for a variety of camera lenses and field‑of‑view requirements.

Choosing the right angle is easy: Pair a 90‑degree beam with 2.8–4mm lenses for short‑range monitoring up to around 10 meters. For mid‑range distances, a 60‑degree angle matches well with 6mm lenses. An 8mm lens works best with a 45‑degree angle, offering up to roughly 20 meters of range. Longer focal lengths like 12mm and 16mm pair effectively with 30‑degree and 15‑degree beams, reaching up to approximately 30 and 40 meters.

To test the unit during the day, simply cover the light‑sensing component to simulate darkness. In the evening, switch off surrounding lights or place the device in a dark area to observe automatic activation with an IR‑capable camera.

Here is an example of typical camera performance without supplemental infrared lighting:
