An autonomous wireless intrusion detector device comprises a movement sensor and a digital camera. In response to detecting a potential movement within a monitored area, the digital camera is triggered to create and store a set of consecutive full-size digital images of the monitored area, and a set of reduced-size thumbnail images corresponding to the set of full-size digital images, and a set of reduced-size thumbnail images corresponding to the set of full-size digital images, for the new alarm event. The detector device sends notification of the new alarm event and reduced-size image-related event information to an intrusion detection network entity, and sends the set of full-size images only if requested by the network entity. The network entity prefilters the new event based on the received reduced-size image-related event information, and request thumbnail images and/or full size digital images from the detector device for a further event analysis only if the prefiltering results in a judgement that the new alarm is a true alarm based on the received reduced-size image-related event information.
