Methods and apparatuses for false alarm elimination

6) An apparatus that determines false alarms at an entry to an enclosure, the apparatus comprising:

• a first sensor which senses for intrusion of the enclosure and which generates a first reading;
• a second sensor which generates a second reading;
• and
• a processor comprising instructions for generating an alarm if the first reading represents intrusion of the enclosure and the second reading confirms intrusion of the enclosure.

15) A method for determining false alarms at an entry to an enclosure, the method comprising:

• receiving readings from a sensor over a period of time;
• storing the readings at least temporarily in a memory;
• comparing a window of the stored readings to a stored signature, the window spanning a preselected period of time, the stored signature representing a corresponding period of time;
• and
• (a) generating an entry alarm if the stored signature represents intrusion of the enclosure and if the stored readings match the stored signature, or
• (b) generating an entry alarm if the stored signature represents no intrusion of the enclosure and if the stored readings do not match the stored signature.
