Interesting there is another round about way of solving the problem. There is a android app called IP Webcam
Because the camera requirement is during the day why not stick a mobile phone in the birdhouse run the ip webcam on the phone , to be viewed directly through a browser on the computer. Then bring the phone in of a night time and charge it. The only issue I see is will the phone have enough power to run the camera all day? I doubt it.
Something to ponder.
Hey listen guys I appreciate all your thoughts and ideas.
