Barking-dog alarms are a great alternative to owning and caring for a real dog. Barking-dog alarms use an infrared sensor to detect motion. Upon detecting motion, the sensor sends a signal to a speaker, which emits a lifelike dog bark. A good barking motion detector will increase the volume and amount of barking as an intruder gets closer to the sensor to provide a realistic effect. Barking motion detectors can be used to increase the safety of your home, business, RV and more.

Skill level:


  1. 1

    Purchase a barking motion detector such as the REX-10 or Secure Dog alarms. These products are typically available only through online stores.

  2. 2

    Install the appropriate batteries required for your chosen alarm. The batteries are for backup purposes in the event that AC power were to fail.

  3. 3

    Plug the AC power cord into an electrical socket near a window or door.

  4. 4

    Position the speaker so it is not visible to an intruder while being close enough to sound as if there were a dog at the window or door. In order for the motion sensor to work efficiently, the speaker should be aimed at the door or window you want to protect.

  5. 5

    Test the system to ensure that it works and that the sensor is positioned correctly. Switch the system to the "on" mode for the bark siren. Each system is a little different. Refer to your manual to activate the bark mode correctly. Exit the area closing the door or window area you are testing. Approach the door or window as a stranger would. Approach from several angles to determine the range of the sensor. Adjust the sensor as necessary.

  6. 6

    Adjust the volume to the level that you feel is appropriate to ward off possible intruders. This will take a little trial and error.

  7. 7

    Set the alarm to a "home" status when you are not away. Each system offers different options. Some allow for a lighter bird chirping or chiming noise to sound when you are in "home" status so you will be notified when someone approaches your home.

Tips and warnings

  • Never expose any part of the system to water, including rain or humidity.
