Abstract: An apparatus for detecting intrusions into spaces of various kinds such as apartments, offices, lockers, and the like by either authorized or unauthorized persons apparatus monitors a specific portal for intrusion occurrence events using an intrusion sensing unit, which communicates intrusion occurrence information to a remote, and possibly hidden monitor unit. The monitor dynamically counts the number of valid intrusion occurrence signals received from the sensing unit and stores the same in non-volatile memory. The number of intrusions stored in memory can be displayed on a display means at the monitor unit, which, in a simple embodiment would take the form of a single, seven segment light emitting diode (LED) display. In addition, the number of intrusions stored in the non-volatile memory can only be reset by the input of a unique, coded personal identification number (PIN) signal from an input keypad located on the monitor unit.
