cybergibbons Posted November 10, 2013 Share Posted November 10, 2013 I now have several panels that can use prox tags to arm/disarm. Learning the tags is fine, that all works. However, if I present an unlearnt tag to the panels, nothing happens. No warning, no response at all. If I present all four unlearnt tags to the panel, nothing. What's to stop me brute forcing the prox tag? Is there any lockout at all?

matthew.brough Posted November 10, 2013 Share Posted November 10, 2013 Which panels you on about? Galaxy for example does have a parameter that will control how many wrong code attempts happen before it locks out but this is programmable and can be set to infinity. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
cybergibbons Posted November 10, 2013 Author Share Posted November 10, 2013 Texecom Premier Elite 12-W and Pyronix Enforcer. I've not changed any parameters to do with the prox tags as far as I know, though neither are as default and I have changed a lot of other settings.

matthew.brough Posted November 10, 2013 Share Posted November 10, 2013 Both panels I'm not a boffin on so will take a look in the engineer book. The parameter will be user code lockout or something similar as the panels don't distinguish the prox separate from a code in general terms. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
cybergibbons Posted November 10, 2013 Author Share Posted November 10, 2013 Yeah, maybe I wasn't clear - just wondering what the standards say and what installers would do - I presume if it doesn't lock out, that isn't good. There might be other things stopping me brute forcing it like rate limiting, not looked in much depth yet.

datadiffusion Posted November 10, 2013 Share Posted November 10, 2013 I always thought with most panels a prox was essentially handled as a very long user code, i.e. loads of unknowns gets you the same alarm as trying to guess a user code. Ion certainly locks out - for a considerably annoyingly long time - if you try and guess codes. Am certain have had the same with prox before. So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...
matthew.brough Posted November 10, 2013 Share Posted November 10, 2013 Agreed dd that as far as the panel is concerned its a user code. I might be wrong but I don't ever remember anything in the rules about what parameter lockout should be. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
datadiffusion Posted November 10, 2013 Share Posted November 10, 2013 CG I have a feeling it will alarm if you fob it a few more times? I think it is 6 or so attempts with ion I might be wrong but I don't ever remember anything in the rules about what parameter lockout should be. Me neither - might have a look tonight as interesting topic. Anyone here ever tried to figure out a competitors eng code from a 'captured' panel? CG are there any panels on which the code can be read straight off easily? Esp old scannys with the removable NVM chip?

matthew.brough Posted November 10, 2013 Share Posted November 10, 2013 I have to resort to asking engineers nicely for the codes www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
datadiffusion Posted November 10, 2013 Share Posted November 10, 2013 Reasonably easy done with co's that have employees, esp larger ones, I guess.
