Camera for biology class

Have you ever feel that your biology class when you learn about animal, you don't have enough time to do observation or all the information that you gather are all through media but nothing in real live, or even only pictures? When I search around for new tech idea for this week, one of the post from educationworld.com mentions about using video module using flex cam. I don't quite get what it means but I or if my idea is the same. I wonder if there indoor-outdoor zoo can provide high resolution webcam for close observation of its animal. Thus, schools can submit for live feed and the students can obtain live-observation of animal. The zoo can hire tech-observer who will do maintaining job for these cameras and watch out for any worth to notice action such as transition phrase of the butterfly or the giving birth of mammals. Of course not all information would worth to look but it can give you the real time view of these animal. I believe it would be good experience for the students. Wasn't it the best if you can study some animals in biology class and then you can go right home and do quick observation of those animals. Perhaps, at some point, there would be a library of video archive and live feed. And it will always be good for education.
