My 2017 Bird Nest Box should hopefully be up and running later this week, hopefully not too late for this season. This version has two camera: A 'from the side' camera which is a webcam (as described in previous posts), and a 'view from above' camera that uses as raspberry pi InfraRed (IR) camera with Infrared-cut to allow night and daytime viewing, I've added dimmable IR and non-IR led illumination. The RPi camera does video capture via the marvelous program PikrellCam.

I've also included an entrance hole counter and facility to measure ambient temperature and outside light levels.
