I guess I purchased one of the earlier models! I needed to monitor my 97 yr. old Mother. I now have aides, the cameras record 10 sec. segments. I miss quite a bit of the activities. Fortunately I feel I can trust the aides. Plus I just learned if I don't have the newest/upgraded models I can't get online Tech Support. During the pandemic it was excusable! I'm still sorry for this investment. I DO NOT RECOMMEND THIS PRODUCT!! 3rd review- NO CHANGE! I don't trust their products!
