Abstract: A portable security system for detecting and annunciating intrusion into enclosed confines includes a hollow enclosure and a frame which is engageable with the hollow enclosure for concealing it from direct view. A controller is mounted within the hollow enclosure and is operably coupled to a source capable of supplying electrical power. A pressure sensor is mounted within the hollow enclosure in electric communication with the controller and is operable to generate an intrusion signal upon detecting an intrusion condition into such enclosed confines, whereby the controller, when being armed, is responsive to receipt of the generated intrusion signal to generate an annunciation signal annunciating the intrusion condition.

Abstract: A security mailbox includes a generally upright and enclosed housing having a rearwardly positioned mail retrieving opening selectively covered and uncovered by a lockable first door and a mail receiving opening formed in a front end of the housing selectively covered and uncovered by a second door. A mail guide is positioned within the front end of the housing. A hinge secures a first end of the mail guide to an interior surface of the second door adjacent to and spaced from a top edge thereof, whereby the guide moves between a first position for receiving delivered mail when the second door is opened uncovering the mail receiving opening and a second position for transferring such delivered mail into rear portion of the housing when the second door is closed. A clip is attached to the mail guide for detachably securing outgoing mail.
