Claim 5:
6. A method of operation of a night security alarm system of a home, which method comprises:
detecting, by a first detector of the night security alarm system, movement inside the home;
detecting, by a second detector of the night security alarm system, opening of a door connecting the inside and the outside of the home;
detecting, by a third detector of the night alarm system, movement outside the home; and
by a control unit of the night security alarm system,
automatically deactivating the night security alarm system if movement inside the home is detected and then opening of the door is detected and then movement outside the home is detected,
wherein the control unit sets a first status “movement inside” while the first detector detects movement inside the home, sets a second status “opening door” while the second detector detects opening of the door, and sets a third status “outgoing sequence initiated” while both the first and second statuses “movement inside” and “opening door” are set,
wherein the control unit maintains the third status “outgoing sequence initiated” once it has been set while the second status “opening door” is set even if the first status “movement inside” is unset,
wherein the control unit unsets the third status “outgoing sequence initiated” when the second status “opening door” is unset,
wherein the control unit automatically deactivates the night security alarm system when the third detector detects movement outside the home while the third status “outgoing sequence initiated” is set,
and wherein the control unit issues an alarm if the second detector detects opening of the door and/or the third detector detects movement outside the home while the third status “outgoing sequence initiated” is not set.
