Hex Home is a unique way to detect intruders using Wi-Fi. It fills your space with Wi-Fi waves that will, in theory, bend around a person walking through the area, alerting you to motion via a notification on your phone. It lets you monitor your house without cameras. The approach has benefits, but you also can’t directly check in when you get a motion notification, so you won't know what's going on. 

You’ll need the Hex Command hub that connects to your Wi-Fi and two small “Senses” that plug into an outlet to monitor a 1,500-square-foot area. You can purchase more Senses for larger homes.

The company says the system is “pet proof,” since the sensitivity of the motion capturing can be adjusted to weed out furry friends or robot vacuums. I particularly like that there are three modes: Home and Away, which are typically standard for security systems, plus a Vigilant mode that will alert you of motion without setting off the sirens. It could be good if you want to be alerted of an elderly family member’s movement throughout the day or to be sure your kids made it in after school. Hex is expected to release this summer.
