We have the doorbell + 4 camera system tied to our WIFI. The remote app on Android works 100% of the time. The app is easy to use and allows us to view previous detections as well as real-time video of our remote home. The night light video is adequate up to about 80 feet, then it's too dim to identify anything. I was concerned that it would auto-restart and monitor since the power is interrupted frequently, but it always resumes when the AC power comes back. I really like this product and the easy installation. I never read the manual... to me that is the definition of a "smart" product.
