Bought the unit thinking it was a good idea which it is. Stand alone unit only needs power and saves all the images to an SD card.The bad:- only accepts up to 1 gb SD card. It takes too many pictures and will fill up the memory card in no time.- battery only lasts 3-8 hours. So you would have to check on it often.- Poor camera if object is in motion. Images are a blur, only very still items are in good quality.- SD card sticks out of side. Anyone can see it, and supect it and also take the SD card!! should have been located in the back out of sight.- price is a bit high for such a poor quality item. might as well invest in a real camera system.- indoor only. plastic construction feels flimsy.
