Homemade Driveway Alarm

Choosing the Right Alarm

• When choosing a driveway alarm, the homeowner must consider what they want the alarm system to accomplish. A casual alarm system can alert you to when a guest arrives if you are out of earshot of the driveway, while a more advanced system can alert you to an intruder and set off safety precautions such as security lights.

Installing the Post

• Choose a place in your yard on the side of the driveway to install a post. With a fence post digger, dig an18-inch hole. Fill the hole with 6 inches of gravel for drainage. Insert upright a 3 foot long, 3 inch by 3 inch fence post. Check straightness with a level. Fill the sides with ready-to-mix concrete. Tap the sides to displace air bubbles. When the concrete is dry, you can finish the post with a decorative cap.

Installing the Alarm

• When the post has set, attach the motion sensor to the post facing the driveway. Plug in the receiver in the room in which you wish to monitor the driveway.
