MOTION SENSOR MOUNTING CONFIGURATION

1 . A method of mounting a sensor in a region, comprising:

mounting at least one motion sensor within a region, the at least one motion sensor having a detection area, and having a central axis of detection within the detection area; and

orienting the at least one motion sensor so that the central axis of detection diagonally intersects a floor of the region at an angle within a range of 20°-70°.

2 . The method of claim 1 , wherein said step of mounting at least one motion sensor within a region includes:

mounting a first motion sensor on a ceiling of the region such that a detection area of the first motion sensor covers a first portion of the region; and

mounting a second motion sensor on the ceiling of the region, the second motion sensor being adjacent to the first motion sensor such that a detection area of the second motion sensor covers a second portion of the region.

3 . The method of claim 1 , wherein said step of mounting at least one motion sensor within a region includes mounting the at least one motion sensor on a wall of the region.

4 . The method of claim 1 , wherein the angle has a value within the range of 30°-60°.

5 . The method of claim 1 , wherein the angle has a value within the range of 40°-50°.

6 . The method of claim 1 , wherein the angle is a 45° angle.

7 . The method of claim 2 , wherein the motion sensor is a passive infrared motion sensor.

8 . A method of mounting a sensor in a region, comprising:

mounting at least one motion sensor within a region, the at least one motion sensor including a first sensing eye and a second sensing eye, each of the sensing eyes having an associated detection area, and having an associated central axis of detection within the detection area;

orienting the first sensing eye so that its central axis of detection diagonally intersects a floor of the region at an angle within a range of 20°-70° and so that the detection area of the first sensing eye covers a first portion of the region; and

orienting the second sensing eye so that the central axis of detection diagonally intersects the floor of the region at an angle within a range of 20°-70° and so that the detection area of the second sensing eye covers a second portion of the region.

9 . The method of claim 8 , wherein the central axes of detection of the first sensing eye and the second sensing intersect at an angle of approximately 90°.

10 . A motion sensor configuration, comprising:

a region defined by a floor and at least one of a ceiling and a wall; and

at least one motion sensor mounted within the region, the at least one motion sensor having a range of detection and a central axis of detection within the range of detection, the at least one motion sensor being oriented so that the central axis of detection diagonally intersects the floor of the region at an angle within a range of 20°-70°.

11 . The configuration of claim 10 , wherein the at least one motion sensor includes a first motion sensor and a second motion sensor, the first motion sensor being mounted on a ceiling of the region such that a detection area of the first motion sensor covers a first portion of the region, and the second motion sensor being mounted on the ceiling adjacent to the first motion sensor such that a detection area of the second motion sensor covers a second portion of the region.

12 . The configuration of claim 10 , wherein the at least one motion sensor is mounted on a wall of the region.

13 . The configuration of claim 10 , wherein the angle has a value within the range of 30°-60°.

14 . The configuration of claim 10 , wherein the angle has a value within the range of 40°-50°.

15 . The configuration of claim 10 , wherein the angle is a 45° angle.

16 . The configuration of claim 10 , wherein the at least one motion sensor is a passive infrared motion sensor.
