The two uses a 2.4GHz proprietary wireless signal to form an elliptical sphere that's a monitored area.

When motions are detected within that sphere, the system will send an alert to the owner's smartphone, nearly in real time.

The system takes just a few minutes to set up.

In open space, you can place the two units some 50 feet apart. But if there are walls in between, this distance is reduced to just 30 feet or even less, effectively shrinking the the protected area.

The Aura is best suited for a very small home, like a guest house or an Airbnb apartment.

Unfortuatenly, at $500, the sytem is more expensive than many other camera-based systems that have more to offer.
