BUYER BEWARE! This app and its cameras work great, but after some time (about a year), your notifications will not display a short video, and will only show a thumbnail. They prompt you to buy a "plus" service in order to keep showing your videos. That cost is 19.99 PER CAMERA! A COMPLETE SHAM of a product. EDIT: My reply after Wyze response. The cams used to give a 5 or 10 second video when I was alerted. Now I am stuck with a thumbnail picture. EVEN WITH MY SD-CARD INSTALLED.
