1. A system for monitoring an environment, said system comprising:
- a plurality of sensors, each sensor generating respective events in response to activity in said environment;
a processor in operative association with the sensors, and at least one stored set of linked events accessible to said processor, wherein said processor is responsive to an event being generated by a sensor to determine whether the event is in a sequence of events corresponding to a stored set of linked events and wherein said system is responsive to the sequence of events not matching a stored set of linked events to generate an alarm.

Abstract
A system for monitoring an environment comprises a plurality of sensors, each sensor generating respective events in response to activity in the environment. A processor is in operative association with the sensors, and at least one stored set of linked events are accessible to the processor. The processor is responsive to an event being generated by a sensor to determine whether the event is in a sequence of events corresponding to a stored set of linked events and to generate an alarm accordingly.

12. A system for monitoring an environment, the environment comprising a premises having at least one entry point providing access from the exterior, said system comprising:
-
a plurality of sensors, each sensor generating respective events in response to activity in said environment and including an authorising sensor arranged to authenticate an individual'"'"'s identity and a sensor associated with each entry point and which is operable to detect whether a door/window at the entry point has been opened, a processor in operative association with the sensors, and at least one stored set of linked events accessible to said processor, wherein at least one event in at least one of said at least one stored set of linked events includes authentication of an individual by said authorising sensor, wherein said processor is responsive to an event being generated by a sensor to determine whether the event is in a sequence of events corresponding to a stored set of linked events and wherein the processor is arranged to generate an alarm unless a sensor associated with an access point generates an event in sequence with authentication of an authorised individual by said authorising sensor and matching a stored set of linked events. - View Dependent Claims (13, 14, 15)
