This was expected after drone privacy debates has become mainstream. And I expect there will be more and more such kind of devices in near future.

I think this is not yet fully developed to be commercialized from technical characteristics point of view. 


"System Specification

The Primary Command and Control Module can typically communicate with nodes up to 200 feet away. 

Each Detection Sensor Node can typically detect drones within 50 feet in all directions.  Frequency detection range is 1MHz - 6.8GHz." 

From 50 feet away you can hear it :). ... for triangulation, I think 50 feet is too short.

Maybe now, small radar kits such as MIT Coffee Can Radar (I mean modified smaller version), Radarduino for private use will be more popular (because of their 1km detection range??).

What do you think guys?

  • Just last night, I was wondering what ever became of that microphone-based drone detector.

    The product does not address its main purpose: privacy. It just lets you that something is out there. Could be your neighbor's tracking dog collar or your neighbor's wireless baby monitor. 

    The fact that this is being designed tells me that the impracticality of "spying" with drones is not really understood. 

    There is money to be made off people's irrational fears. 

  • This is comical.  A 50ft range of detection?  Wow, good thing none of our aircraft can fly higher than that or it would never detect us!! Also note that it only can detect an aircraft with a transmitter on it.  So if you do not have video or telemetry being transmitted back to you, there is nothing to detect.

  • They mentioned 3drobotics so many times that i think that is just a little bit of free advertising

    Interesting but pointless.

    Detection of a 433Mhz/900Mhz/2.4GHz etc signal means not a lot. It could be a quad/plane, a phone with WiFi enabled, laptop, microwave, garage door opener. Loads of things use those frequency ranges. Once you are "aware" it's there what next? If it's flying legally there's not much you can do about it. Jamming it's signal would be illegal in most countries and if you caused it to crash that would be criminal damage in the UK and probably something similar in most other countries. At best you'd be paying for a new quad for someone at worst you could cause it to crash into someone.

    If the thing was running an autopilot then it would RTL (hopefully) or continue it's planned route anyway when it lost signal so it'd achieve nothing. Maybe someone should scale this http://motherboard.vice.com/blog/finally-face-scrambling-glasses-to... up to house size instead :)

  • I see a business model here that could be used to help fund future drone development...

  • You can already buy cell phone jammers on ebay, so 900mhz- 5.8ghz jammers will be no problem and combined with a direction antenna on transmit deluded media brainwashed folks could take down rc toys. Leave it to ebay and kickbeggar schmoozers to try and sell them.

  • KOIN 6 news - "They won't be shooting the drones down, just stopping them from completing their mission."

    What an absolute load of drivel!

    Sure, there are plenty of commercial operations out there that would love something to stop drones going anywhere near their livestock or product such as pig farmer in US, chicken farms in UK, eucalyptus loggers in AUS. Keeping prying eyes away may even be worth millions to some players, but this product is completely useless to them and is instead aimed at consumers anyway. No consumer, regardless of how affluent or paranoid, is going to shell out for this type of product.

    The stated range of detection for the Personal Drone Detection System would make it difficult detect a drone entering the immediate confines of a tennis count, much less notify you prior to becoming aware of it with your own unassisted senses. In fact, you would need a wide network of dozens and dozens (possibly hundreds) to create any sort of practical buffer zone around a point to be protected. The nodes would, of course, need to be mounted on top of tall booms of various elevations, which would cost an absolute fortune. Even then, many of these booms would have to be up to 350ft above ground level in order to have any hope of detecting a drone flying below it's maximum allowable height of 400ft. The cost of constructing one 350ft tower would be millions along. Even if the nodes were mounted on a team of tethered drones in order to drastically reduce the cost of getting the requisite height, it would still be millions. And all for detection?
    Totally and absolutely useless to both consumer and industry.
  • Target market: those who are paranoid and ignorant of what "personal drones" actually do.
