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.

Well for starters I believe it is one way wireless. 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.

the freq isn't really the issue with it.
