Three and a half stars. I have bought several cameras and they work perfectly. Very clear images during the day. At night, you can see images much better from more than 10-15 feet away if you use supplemental IR illumination or an outdoor light that illuminates the scene. Cameras can be very sensitive to movement and sound. They help protect the house and give me peace of mind whether I'm inside or outside. One of the batteries died pretty much exactly after a year of use, after a charge or two. I expected it to last at least a few years. Disappointing as the particular camera that had the battery was mostly off (via the phone app) about 60% of the time over the year and the batteries aren't cheap as they are around a third of the cost of the camera. Camera; but other than that I'm satisfied with the overall usefulness of the cameras.
