Home security device ditches video for audio surveillance
For Airbnb hosts who want to keep tabs on their homes, a full home security system might be overkill. They’re expensive, and live cameras and motion detectors invade guests’ privacy. So how do they make sure guests keep the volume down, aren’t smoking inside and don’t ransack their home?
A new device called Point combines microphones with environmental sensors to detect anything out of the ordinary in your home while you are away. A broken window while you’re at work, the sound of your teenagers throwing a raging party, Grandad sneaking an unauthorized after-dinner cigar.
“They want to have peace of mind and know that everything is fine, but they don’t want or need full security systems,” said Nils Mattisson, co-founder of Form Devices, the start-up that makes Point.
Small, round and plastic, Point looks like a traditional smoke alarm crossed with a speaker. Sounds are matched with data from the other sensors to figure out what might have happened — a loud crash followed by a drop in temperature might mean a window was broken. It hears when an existing smoke detector goes off and sends an alert, though it’s not certified as an official smoke detector on its own.
It has a microphone that can detect sounds outside that the human ear could pick up. Environmental sensors pick up temperature; the particle sensor can tell what’s in the air.
