Video: Infrared night vision with the NoIR V2

The primary advantage of the Raspberry Pi NoIR camera is seeing in complete darkness. By using an Infrared light source - completely invisible to the human eye - images and videos can be captured with no visible illumination whatsoever.

 

This video was shot in complete darkness with the new NoIR V2 camera. All illumination comes from two Infrared LEDs powered from the Raspberry Pi itself. It's an example of a common use of night vision - security and surveillance.

A rather shifty looking character sneaks through the front door under the cover of darkness, but is caught on video!

 

These are some still photos taken under the same low light conditions, captured at the full 8 megapixel resolution the NoIR V2 offers.

    I used a pair of VISHAY VSLY5850 LED's powered by the 5V rail on the Pi, linked up in series with an 18 ohm resistor. There is a great data sheet on the element14 product page that should have any information…

    How many lumens or mcd are those IR LEDs?

    Thanks,

    So they output about 600 mW/sr.

    If this was visible wavelengths, we could say that is about 410 candela, if I have the math right.

    Assuming that LED has about a 20 degree illumination angle, it implies each LED is emitting the equivalent to visible illumination of about 39 lumens or 78 lumens for the pair.
