Abstract
A method of monitoring a fence or other containments barrier for climbing events by an intruder comprises providing a first and second sensors at different heights on the fence, detecting from each of the sensors signals which are indicative of vibration of the fence, and comparing the signals from the first and second sensors to determine vibration events which change in relation to a height of the intruder on the fence indicative of climbing so as to distinguish climbing events from incidental events and to provide a signal in response thereto.
