Hello, We are looking to replace our nanny cam (which is horrible) and get a really good one. We want a wireless one that will transmit up to the house to a tv. The house is abouit 300 ft and has to go through walls/trees. color is prefered but not a must. Night vison mode is a must though. Does anyone have one that they really like that will work for use? If so, where did you purchase it and what is it called (Model/serial numbers appreciated if you have them)? If you dont mind sharing the cost of your camera, please do so. THANKS!
