Scare Intruders With Realistic Barking

Protect your home with a specialized motion detector designed to simultaneously alert you and deter intruders. The Rex Plus Electronic Watchdog is always on duty, guarding and protecting. Rex can sense motion through thick doors, walls or glass. When motion is detected, Rex sounds one of four selectable alerts: an angry, barking watchdog, soothing sounds to alert you of a guest's arrival, alert sounds of both an angry watchdog and a warning siren, or continual tranquil sounds of the rainforest.

  • Senses movement through walls, doors and glass
  • Barking gets more frequent as intruder gets closer
  • Plugs into any standard electrical outlet
  • Adjustable volume
  • Hear Bark Sound

The closer an intruder gets, the more frequent the barking. With an angry dog barking, intruders are encouraged to leave, and you have time to prepare if they stay.
