868MHz Technology Explained


The EasyFit Alarm from Yale uses a frequency that is more tightly controlled than many used by DIY alarm systems, meaning a clearer channel with less interference. The 868MHz frequency has a short duty cycle of 1% as defined by regulation, meaning that any one device can only transmit for 1% of time , leaving the channel 99% of time free of transmission. This means that where there are multiple devices operating, they are less likely to collide resulting in a higher performance. Other devises that operate on a higher cycle are far more likely to collide and result in interference.

Rolling Code Technology Explained


When a controlling device (keyfob, keypad etc) transmits a signal to the control panel, it will transmit a unique code alongside the actual message. This code allows the control panel to check whether this device is an authorised device; if it’s not an authorised device (for example your neighbour’s keyfob), the control panel will ignore the message. Problems can arise when the unique code is intercepted as in many DIY systems, this unique code remains the same for every transmission. If someone intercepted this code, they can possibly mimic this code and send a command to the control panel illegally. The Yale EasyFit Alarm’s Rolling Code Technology prevents this by ensuring this unique code is different for every transmission. If someone intercepted this code, it would have already expired and cannot be used to control the system, adding an extra layer of security to prevent unauthorised access.
