For something like this, the margins for acceptable false positives and true negatives are basically nil. There aren't too many things in this field that have 100% accuracy, and it would have to be very close to be a reliable product.
I couldn't find any details on the tested rates or other technical details on the Aura site, which is expectedly very markety: https://www.aurahome.com/
If this thing wakes me up one time to tell me an unexpected person is in the house and it's a false positive, it's now essentially no better than a $30 motion detector I can get at Home Depot.
I'd also be concerned about people jamming this from their car, a vulnerability that a $30 motion detector from home depot wouldn't have. Either jamming sets off the alarm which opens it up for nightly abuse until you throw it out, or it doesn't set off the alarm and then your house is vulnerable.
Are you sure? I think it was a common theme in Poland that the burglars would stake out an area in summer, looking for people leaving for holidays, and break in when they know it's likely to be empty for a couple days.
So they're not targeting anyone in particular at first, but it's still not really a crime of convenience the way a mugging or bike theft might be.
I meant that they'll choose the easiest houses, even if they spend effort casing them. I'm sure those Polish burglars were avoiding the riskiest homes.
Let's set up some reasoning, flawed maybe, but with a few steps.
1. Are you allowed to jam someone's alarm system? I think that might be reason enough to go to the police. The problem is that the police won't have the expertise to do much about it.
2. For a thief it might not be the smartest thing to carry this around or be near, even if it's in a car. It's like a siren. You don't want to draw attention to your location. I can't imagine a burglar carrying this on them.
3. So, as a burglar you'll have to place a jamming device somewhere and have it go off while you're not there for a very short time. Too short for anyone to pinpoint it and a bit randomized over the night.
4. This is a single attack towards the sensors in your home. A combination with the $30 PIR sensor and some sensor fusion would make this attack much harder. The burglar has to blind the PIR sensor with e.g. an infrared light for a while at the same time which is a physical contraption that is harder to hide. (More likely than: https://www.youtube.com/watch?v=6ggVka_zBis :-)).
5. Top it off with microphones and cameras and you're golden.
6. The big question is: "Do people care enough about real-time detection?". I think the largest market is about catching that bastard! If the police can give me some figures - say a 50% probability - that a person will be arrested if I add some camera system, that would resonate with deeper feelings of justice and long-term prevention of this type of behavior. The justice system works quite simple as well "catch someone in the act". If the police only finds stolen jewelry later on, the judge has much shakier grounds to convict someone.
For something a bit more pro-grade (for a very close price) check out Xandem Home, the Tomographic motion detector. It even creates a map (in the app) reminiscent of harry potter's marauder's map:
