Perimeter Alarms – Self Assessment
I have perimeter alarms set up if needed on my property.
Our first layers of detection are:
- Video Doorbell
- Outdoor Motion Lighting
- Outdoor Motion Security Cameras
These systems typically alert us to movement within 50 feet of the home.
Perimeter alarms extend that detection beyond the 50-foot zone.
They notify you earlier — before someone reaches the house.
Think of it as pre-50-foot security.
When Perimeter Alarms Make Sense
Perimeter alarms are useful when your property has areas that extend well beyond your home, or specialty areas.
Examples:
- A long driveway
- A large yard or acreage
- A dock or waterfront access
- A path or ramp leading toward the house
- A side or rear gate
- A pool or hot tub latch
For example, when I was growing up we had a waterfront property with a dock and a long ramp leading up to the house. A perimeter alarm at the dock would have alerted us the moment someone stepped onto it.
Some models are pet-immune, meaning they only trigger on humans.
Types of Perimeter Alarms
- Infrared beam sensors
- Outdoor motion detectors
- Driveway alarms
- Fence vibration sensors
- Laser or microwave perimeter fences
Perimeter alarms are a powerful way to extend your early warning system beyond the home itself.
