Aura is a two-piece security system that can monitor your entire home

Aura is made up of two components: a cube-shaped hub and a small remote sensor that plugs directly into a wall outlet and is about the size of an air freshener. Cognitive Systems recommends placing each component at opposite sides of your home, which will provide coverage of everything in between, apparently regardless of walls, stairs, and other obstructions.

The system uses patented spectrum analysis technology to detect motion any time someone enters the operational area. Aura then sends an alert to the owner’s phone or can activate the siren in the hub. Cognitive Systems claims Aura’s motion detection is more reliable and accurate than traditional systems as it can filter out non-human movement like pets or ceiling fans (or pets on ceiling fans!). As it doesn’t rely on visible light, it operates seamlessly at any time of the day or night.

“When we realized that our technology could understand motion by seeing how the patterns in wireless signals change in a home, we knew that we had something special,” said Taj Manku, co-founder of Cognitive Systems, in a statement. “By using radio frequencies to detect motion, we provide a more dependable solution to consumers by eliminating most of the false detections that occur with traditional sensors.”

Aura will automatically arm and disarm itself when an authorized user leaves or returns to the home. Additional authorized users, like family members, nannies, or dog walkers, can be programmed into the system via the accompanying iOS or Android app. When these users enter the home, Aura will recognize their presence and won’t sound the alarm.

Aura should begin shipping by the end of February and is on display this week at CES, with pre-orders beginning on January 5. For a limited time, early pre-order customers will also receive special pricing of just $399 for the full system.
