The Security Val Video Doorbell is the first doorbell with artificial intelligence. Val detects motion outside of your home, uses facial recognition to greet repeat visitors by name, and notifies your phone whenever a doorbell ring is made. In the Security App, you can see, hear and speak to people outside your home from anywhere. This video doorbell connects to doorbell wires and easily replaces standard wired doorbells. No need to charge any batteries. You can always feel at home with Dusco Security.
