This Kangaroo Motion sensor can be a first layer of defense and can be placed anywhere on the perimeter of your home and send you alerts to your phone.
Building Your Layered Defense?
This product is part of your Detection Layer — but one camera or one doorbell isn’t a complete defense plan. Real layered home defense means four layers working together: Detection, Delay, Deterrent, and Last Resort.
I’ve built a free guide that lists every product I’d actually buy at each layer — with honest prices and what to skip.
