November 23, 2017-I use the Yi! Home motion sensing camera and am elated with the performance. I placed the camera in my front window facing the sidewalk. I receive text alerts when someone approaches my front door and the camera records up to 5 days with the 32gb micro SD card ( not included-$10 additional). The camera features night vision and motion tracking. When it senses movement near my door, it sends me an alert with a ten second video clip.
This is an interior camera, but Yi! also offers an affordable exterior camera.
Most important, I do not have to pay a monitoring fee to a security company so the cost is one time.
