fatman Posted April 28, 2016 Share Posted April 28, 2016 Hi all, New to the Forums, so apologies if in wring section; mods please move if needed. There's lots of posts slating Yale products, but I can't understand why? Is it because they are ungraded? Or is there another reason I should know (I have one myself!). Sorry if this is a basic question. I searched, but could find nothing saying why they were bad, just that they are! Thanks in advance.

I did have a read; it was mainly referring to the old Yale systems being problematic due to low frequency. I have the 'Easy fit' telecommunicating alarm which uses the same frequency as the Pyronix Enforcer, so I feel a little better now Thanks again for the info.

sixwheeledbeast Posted April 28, 2016 Share Posted April 28, 2016 Frequency is only the transmission, security not related there. Quote Link to comment Share on other sites More sharing options...

Oh :/ Sorry I must have misunderstood! As I'm sure you can tell, I am not very knowledgeable about Alarms - in fact, I didn't know there was so much to Alarms until I recently found this Forum! But I am finding it all very interesting! So, sorry to be such a noob but if the frequency isn't the issue with security; please can you explain what is?

This means the device (your sensor) transmits a message with the hope it gets there (the panel), it may or may not. I also believed the encryption of the signals was either flawed or none existent on these DIY kits? One way is only suited for very very low risk, many installers refuse to install it at all. 1 Quote Link to comment Share on other sites More sharing options...

Thanks for this really helpful post. I appreciate the explanation too. This makes much more sense now so thanks again. I'm moving house soon, and there is already a wired system in, so I I can get that services and it is working ok, I think I will use that instead! Sorry for another basic question, but would a two way alarm communication between panel and accessories confirming system armed? Can't give 'kudos' on my Mobile for some reason, but will do when on a PC! Quote Link to comment Share on other sites More sharing options...
PeterJames Posted April 28, 2016 Share Posted April 28, 2016 On a two way system the detectors and control panel communicate with each other, the detector knows when the system is armed therefore they dont transmit detected movement when the system is unset. Two way control panels can also randomly pole the detection and if it does not receive a reply it knows it is missing. Some one way systems do have poling but this is initiated by the detector and the control panel is expecting a pole from each of the detectors within a set time period normally 24 or 12 hours. Sometimes with one way systems two detectors pole at the same time which makes the panel think that it is being compromised, or it just does not recognise the poling and goes into pole failure. I dont believe the Yale system poles at all, meaning that the panel would not know at all if the detector was missing. 1 Quote Link to comment Share on other sites More sharing options...

I now feel like I know the flaws of these types of systems, and think when I move house I will switch to a decent Wired one. Thanks again to all the really helpful replies. I've been unable to give anybody 'kudos' which I thought was because I was using the Mobile Site, but I'm on a PC and still can;t, so I'm guessing it is because I'm new? Either way many thanks for the replies everyone Quote Link to comment Share on other sites More sharing options...

cybergibbons Posted June 29, 2016 Share Posted June 29, 2016 We've just published a blog about why these alarms are not great. Stick with graded wireless or wired if possible. If you look on my personal site, you can see what I think of the various systems. https://www.pentestpartners.com/blog/alarm-systems-alarmingly-insecure-oh-the-irony/ The short of it - easy to jam, easy to replay disarm signals, you can sniff the PIN over-the-air if you use a remote keypad, you can brute-force the PIN as well. I reported these issues to Yale 4 years ago. 1 Quote I have a blog, some of which is about alarm security and reverse engineering:http://cybergibbons.com/ Link to comment Share on other sites More sharing options...

cybergibbons Posted June 29, 2016 Share Posted June 29, 2016 They seem to have had a bit of an odd history with alarms, looks like they were a bit more like ADT a long while back, then went to just consumer, and are now back trying some pro installs. 1 Quote I have a blog, some of which is about alarm security and reverse engineering:http://cybergibbons.com/ Link to comment Share on other sites More sharing options...

Not sure why either company was particularly worried about the other, especially at the time, but there we go, all ancient history.
