Ms. Foster wants a video doorbell. Understanding what she wants, I am looking for a motion-sensitive camera that will: 1. Turn on when someone comes on to the porch. 2. Will notify me when said person/critter is on the porch. 3. Is WiFi to a cell phone. 4. Will record when triggered. 5. Is battery operated. As I have more than my share of of old, but still functioning cell phones with video recording capabilities, that would be my choice. I donít need one to contact my phone when I am away, because in our area, phone service is sketchy at best. Any suggestions?
