I wanted to use this to watch pets. It did well with motion detection; picture is good; took a long time to figure how to get whole area into view without mounting to the wall; brought in a shelf. But, there's nothing in the description that tells you the Sim Card will not work except with a Widows computer. I have a Mac, so I couldn't see anything that I had thought was being recorded during the night. Most of the situation with this was frustrating; the booklet that comes with it is not much better than the website manual, which I could download on my Mac. I would not recommend this product though.
