Addressing Colour Issues With Bird Box Cameras

Our Green Feathers SD wireless and wired bird box cameras do not feature a mechanical IR filter. This means the camera does not filter out infrared light, to enable night vision functionality. When a lot of this IR light gets reflected back in to the sensor, the image can have a purple tint at times.

This can be reduced by:

1. Introducing more natural light to the bird box, via a perspex window or similar.

2. Introducing artificial visible light in the day. We have a Daylight LED lamp that only runs during the day to not disturb the birds

3. Minimise reflection of the IR LEDs. Covering some of the LEDs or using tissue paper or similar to diffuse the light may help.

The main goal of any of these steps is to increase the ratio of visible light to infrared light in the birdbox, to aid with the colour the camera gives.
