You want to keep tabs on your weekend house, rental property, or condo. You also don't want to invade your guests' privacy. The Aura Home Monitoring System has a solution. It detects disturbances in your Wifi network's pattern and runs them through an algorithm that lets it "see" things like potential intruders while recognizing harmless movements from pets and/or cleaning robots. Two beacons are included in the starter kit, enough to cover 700 square feet. More beacons can be added for added coverage, and since it has no microphones or cameras, you can guarantee privacy.
