A dog owner installed a Smart Security System, because she wanted to make sure that her dog-walker came and left at the agreed time and that her dog got all the benefits she paid for. When the dog-walker entered the apartment and turned off the smart security system, a notification message was sent to the owner. The second notification message was generated when dog’s cage was opened. Later notifications were sent when dog’s cage door was closed and the security system turned on. The owner knew when the dog-walker came and left, as well as how long the dog was outside. Through an indoor camera she could observe and verify the event. Woof, woof, a one happy dog!
