Cocoon puts an ear to the ground, uses ‘infrasound’ to detect home intruders

Now that the smart home zeitgeist has really begun to take hold, there’s no shortage of low-cost DIY security systems on the market. They’re as common as pigeons these days, and there are hundreds –if not thousands– of different companies with their own take on the idea. But even in a space that’s become extremely crowded in the past couple of years, there’s still plenty of room for innovation.

Case in point: the Cocoon security system. In addition to all the requisite sensor tech we’ve come to expect from a device in this category (motion sensors, HD camera, smartphone connectivity, etc.), Cocoon uses a combination of infrasound and machine learning to detect intruders — no matter what room they might be in.

To help clarify that a bit, infrasonics is the study of low frequency sound waves that are below the range of of normal human hearing (around 20Hz or below). Seismologists have used this technology for decades to detect shockwaves caused by earthquakes, and now Cocoon brings it into your home. The device listens for infrasonic disturbances, and with the help of machine learning, can apparently discern normal activity from suspicious activity, pushing alerts to your smartphone when anything fishy is detected.

According to Cocoon’s creators, this technique allows the device to monitor your entire house from a single point. Infrasound detection makes it possible to sense intruders through walls and closed doors, which –if the technology actually works– would effectively solve many of the problems faced by traditional security systems, which are generally limited to a single room, or require multiple sensors to be installed throughout your home.

The company has already produced a number of working prototypes, and has recently taken to Indiegogo to gauge consumer demand and bankroll Cocoon’s first production run. If you back the project now, you can pre-order the device for around $250 to $300. The company expects to ship the first units to backers sometime in Q4 of next year, assuming the campaign reaches its $100K funding goal and manufacturing goes smoothly.

Use this tool to see where your smart home devices are sending data

It might feel like your collection of smart home devices are just communicating with each other and with you. Odds are, that isn't the case. The data from your devices can be sent all over the place to communicate with servers and may even be in the hands of people that you might not expect. Now, thanks to some savvy researchers at Princeton University, you can monitor your smart devices and see exactly what kind of information they are collecting and sharing.

A new tool called Princeton IoT Inspector, available for MacOS, offers an easy-to-install and configure option to better understand how your smart home devices communicate and behave while in your home. To be clear, this tool is essentially designed to spy on your home. It utilizes similar tactics that a bad actor might use to discover what is running on a network. Except instead of exploiting that information, the tool collects data that can be analyzed by you and by the team of researchers.

Smart home services are often positioned in a way that suggests they will make us safer. But what happens if that tech falls into the hands of an abuser? A woman said she was stalked and harassed by a former partner using smart home technology, according to a CBC report.

Ferial Nijem shared her story with the Canadian publication, highlighting how internet-connected everything can put a person in a dangerous situation if used with malicious intent. According to Nijem, her partner would often check in on her using security cameras placed around the house. He would keep an eye on her even while thousands of miles away from home. He would constantly check in with her via FaceTime, requiring her to show him if she was with anyone else.
