Your Wi-Fi can now double as a home security system — Gamgee uses home Wi-Fi networks for intruder detection

Dutch startup Gamgee has launched a crowdfunding campaign for a home security system that detects physical intruders using your existing Wi-Fi system. Using a home mapping app and artificial intelligence, Gamgee’s Wi-Fi Home Alarm is claimed to offer precision protection by ‘body printing’ the household’s trusted people and pets. Alarms can be configured to detect body prints with unrecognized mass, gait, or movement signatures, thus triggering an alarm.

As you can see in the video above, Gamgee's tech promises to bring new meaning to the term ‘Wi-Fi security’ in the home thanks to its physical intrusion technology. However, as with all new, unproven tech, we'll have to see it in action to assess how well it works. However, the theory behind the tech is sound — we have previously reported on Wi-Fi human body detection, with researchers at Carnegie Mellon University detecting the position and poses of humans in a room using off-the-shelf routers. The Gamgee development team seems to have fine-tuned this detection ability to commercialize their novel whole-home alarm system.

In the Gamgee Wi-Fi Home Security FAQ, we learn a little more about the underlying technology and techniques. The tech relies on a mix of Wi-Fi sensing and AI and uses the Channel State Information (CSI) in Wi-Fi signals to detect the intricacies of motion within your house.

When you receive a new Gamgee Wi-Fi Home Alarm, you will need approximately two weeks to train it. During this time, the system will learn family and pet body prints. You might also consider training it on frequent guests. For caregivers, the company claims it can detect when a person or a pet isn’t acting in their usual manner. Thus, the system can detect if someone has had a fall or accident or is in distress.

Mapping your home is another important part of onboarding the Gamgee Wi-Fi Home Security. Users digitally map their house by walking alongside the walls in all the rooms. Around the same time, it will become apparent if and where you need to add extra mesh extenders. On the IndieGogo project page, you will see Gamgee is offering funding perk levels with hardware starting at €295 ($320) for a system with three extenders. This is enough for a ‘medium house’ of 150 square meters (1,600 sq ft), it says. A four-pack is offered at €345 (374) for approximately 200 square meters (2,150 sq ft) of security coverage.

While this project is fascinating and seems to hold great promise, there are several things to be wary of. Firstly, we always advise readers to be careful with their money, as backing a crowdfunder isn’t the same as purchasing a product outright. Secondly, it is much easier to promise a great product than to deliver one, so third-party reviews are essential here. The Gamgee Wi-Fi Home Alarm seems to be a product that would be particularly susceptible to detection glitches, as it simply promises so much precision and detail. Thirdly, even the AI giants aren’t getting it right all the time, far from it. AI hallucinations and blatant errors seem to be commonplace in 2024, and accuracy would be paramount for a system such as this.

Gamgee doesn’t expect to ship the first Wi-Fi Home Security systems until January 2025.

    Regarding the last full paragraph:

    "While this project is fascinating and seems to hold great promise, there are several things to be wary of.

    The paragraph should be in bold print.

    I expect it'll suffer from blind spots and false positives (i.e. failing to recognize an occupant that it should). I'd be more worried about the latter than the former, since an intruder can't stay only in the blind spots.

    I find it intriguing that someone decided to productize this tech, but if they can't get the false-positive rate low enough without causing too many false-negatives (i.e. missed detections of unknown individuals), then it'll fail. Imagine the bad press it would get from a break-in that it fails to detect!

    Another risk would seem to be Wi-Fi jammers. The base station better know how to recognize when it's being hit with a jamming attack and it better have a hard-wired internet connection to inform you of that.

    Hallucinations apply to generative AI, which this isn't. Yes, the accuracy concerns are definitely a fair concern to raise (as I mentioned), but given how much press AI topics are getting these days, you'd hope the author would be more familiar with the jargon and use it correctly.

    Furthermore, there's really no comparison between the type of deep learning models used in such a detector and LLMs. Pointing to hallucinations by LLMs is like talking about rocket launch failures in the context of discussing airplane safety. That's about how far off the mark it is.

    In some says using the word hallucinations might be better in some ways when dealing with a non technical audience even though it really isn't correct. It is surprising how well know the concept of AI hallucination is by the general public...seems to be trendy on social media. Lately any software is called "AI" and since it is seeing things that do not exist it is kinda correct.

    In the end if it scares off a few non technical people who throw money at stupid stuff maybe a valid misrepresentation.

    One possible advantage to this system would be WIFI jamming, that's becoming more common in break-ins to disable cameras, being useless.

    I'm sure wi-fi jamming would disable this system, also.

    If you merely wanted an alert when a wi-fi jammer is in use, jammer detection is a feature that could be integrated into a standard wi-fi router.

    This system is looking for 'devations' from normal WIFI signals. Jamming expressly causes deviations in the signal. It will be the same as blowing an air-horn in a microphone field. Blatantly obvious.

    Not just any deviations, but structured ones that it recognizes as being caused by people in the home. You don't want some kids playing outside to set it off, nor do you want a piece of furniture being out of place to cause false alarms. So, it not only needs to be quite sensitive, but also very selective.

    And it also disrupts communication with the mesh extenders, rendering them pointless. But, you don't even need a system like this to detect a jammer. I'm sure a run-of-the-mill wi-fi router could do it, were it designed to.

    The grey shaded text in Post #4 is not mine. I did not write that text.

    I was only referencing the entire paragraph from the end of article which includes the sentence attributed to me.

    I did apply bold font to the entire paragraph which I noted in Post #2.

    The objective being my belief that the risks regarding crowd-funding, etc. should have been high-lighted all that much more.

    Just keeping the record straight.

    Apologies. Fixed.

    Note how I use a
