cybergibbons Posted May 8, 2013 Posted May 8, 2013 Sounds interesting. Have you got any patents or anything juicy to look at? It looks like it works on signal strength between multiple nodes on the 2.4GHz spectrum. I'd imagine you have to be doing some pretty hefty DSP work to get it producing meaningful results. Also, if you fancy sending some kit for evaluation by someone who loves breaking stuff like this... Ah, found it... https://docs.google.com/viewer?url=patentimages.storage.googleapis.com/pdfs/US20120146788.pdf It sounds quite interesting. I'm wondering if it can be gamed by an active jamming system that very very gradually ramps up the background noise in the channel that is in use... I have a blog, some of which is about alarm security and reverse engineering:http://cybergibbons.com/
chief Posted May 8, 2013 Author Posted May 8, 2013 The Dutch night club sounds interesting.. haha Thanks for the comments Gibbons. We have 4 PhDs at Xandem that all have extensive DSP experience. It's taken years to perfect the technology in this simple form of a motion detector. We have a bunch of far more advanced products in R&D which will hit the market in the next couple years. As for the jamming, our system will indicator poor health and trigger a trouble relay if you reach a level where our detection is degraded. We're yet find a way around the system that hasn't been addressed already. chief
breff Posted May 8, 2013 Posted May 8, 2013 Lol @ what Peter redirected the link to The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not)
Boxshifter Posted May 8, 2013 Posted May 8, 2013 Having a quick read through the patent is this something that can be integrated with existing radio devices I.e wireless detectors so that they would act as nodes within the mesh?
chief Posted May 8, 2013 Author Posted May 8, 2013 Boxshifter, A very interesting idea. It is technically possible if we had access to all the hardware involved so that would could load custom firmware to the devices and the devices played nice with our encryption and custom communication protocol. A bit too much leg work to be feasible. Let me know if you have questions. chief
cybergibbons Posted May 9, 2013 Posted May 9, 2013 Has it been independently pen tested then? I have a blog, some of which is about alarm security and reverse engineering:http://cybergibbons.com/
Joe Harris Posted May 9, 2013 Posted May 9, 2013 It sounds quite interesting. I'm wondering if it can be gamed by an active jamming system that very very gradually ramps up the background noise in the channel that is in use... Ironically the same method as used selectively for gaming quantum network links...
cybergibbons Posted May 9, 2013 Posted May 9, 2013 So just found the PCB from the processing unit: http://i.imgur.com/aHF5eRC.png Looks like a TI CC2540 from the crystal pins and frequency, RF connections and size and type of package. Very similar to the CC11xx chips but in the 2.4GHz band. Difficult to get code out of these unless they are left unlocked.
