Gatecam number 4 is based on an Orange Pi with USB camera board. It replaces an earlier camera made with a Raspberry Pi. The Orange Pi using UVC video and MJPEG Server produces up to 15 fps at FHD (1920 by 1080) compared to a max of 4 fps with the Raspberry pi. I used Armbian, fswebcam and MJPG server. The setup lives part way down our drive and allows us to see a driveway gate that is below the floor level of the house.
And here is the build in progress.
