Hey fellers-fellets Im new to the board with a couple questions. My kids and I enjoy watching wild life-bird watching and my middle child has expressed a recent interest in photography night filming. We have a skunk that lives under out toolshed and uses the sane path every evening when he goes out foraging. we thought it would be a very good Idea to set up an inexpensive wireless setup to capture his activity's.http://www.dynaspy.com/product_info.php?products_id=55 but I dont wnat to have to record hours of empty video and was wondering if there is an infa red switch/motion sensor I could rig up to turn the cam on and off. Also Im not sure if this product comes with a battery. I and my kids thank you in advance for any helpful replies.
