The Raspberry Pi NOIR camera brings the outside world into your Pi as still images or video. Plug it into the CSI slot on any Pi, A, A+, B, B+, Pi 2 by following the supplied instructions and you are ready to go. The NOIR (NO IR filter) is identical to a standard Pi camera (73-6045) except the IR filter has been removed, allowing a whole new spectrum to flood in. Images taken in normal light will have a very different look to them as the NOIR can see colours that you are unable to. The camera really comes into its own when you add good IR illumination (IR LEDs for example) and use it at night. People and animals are largely oblivious to infra-red making the camera ideal for wildlife, or security applications, particularly when coupled with motion sensing software, or maybe as a baby monitor. Infra-red is also useful for measuring photosynthesis in plants which is why the NOIR is supplied with a small blue filter; remove the blue light and what's left tells you how much chlorophyll your plants have. Become a citizen scientist!
The camera has a 5 mega-pixel sensor behind a fixed focus lens (1m to infinity). It shoots 1080p30, 720p60 and VGA90 video. Library support includes the MMAL (multi-media abstraction layer) and V4L (video 4 Linux) APIs, 3rd party libraries and a Python library, Picamera.
Three applications are provided to get you started: raspistill takes still images at up to 2592 x 1944 pixels with control over exposure mode, image preview, white balance, metering mode and more. Raspistillyuv also captures still images and has the same controls as raspistill but it saves raw pixel data at the end of the JPEG file. Finally there is raspivid to capture HD video 1920 x 1080 at 30 frames per second (fps) down to 640 x 480 at up to 90fps. If you want to delve deeper into the inner workings then the source code for all three applications is available in the Raspberry Pi Github repository plus libraries to roll your own software. The internet is bursting with project write ups and ideas for applying your new camera/Pi set-up; time lapse photography, motion sensing, wildlife photography, security, quadcopters, robotics (OpenCV library), and many others. All good Raspberry Pis deserve a camera.
