Abstract: A trespass detection system for notifying a recipient of a possible trespass at a remote location is disclosed. The system comprises a low bandwidth satellite network, and a hand-portable base station positioned at the remote location and comprising a satellite transceiver for communicating with the low bandwidth satellite network, and an image capture sensor located proximate to the base station for capturing an image in response to an alarm trigger, the image capture sensor further comprising a processor for analyzing the captured image to identify a predetermined type of object and on identifying at least one of the predetermined type of object in the captured image, generating a contour image of the identified object, wherein the contour image is transmitted to the recipient via the base station and the satellite network.
