Detection Area Reference
The following table describes detection area calculation related parameters.
- Single Device Deployment
- * The "+0.05" in the formula accounts for the device's mounting offset from the ceiling surface.
Table 1. Parameter Definition Parameters Description Value H Installation height 2.2 - 6 m If attribute identification is required, refer to the following table for the installation height requirements:Attribute Identification Installation height Children&Adult Differentiation 2.2 - 4m Gender Recognition 2.2 - 4m Staff Detection 2.2 - 4m Group Counting 2.2 - 6 m View Direction Detection 2.2 - 4m h Target height Example 1.7 m α Horizontal field of view angle 101° β Vertical field of view angle 70° x Detection range length 2 × tan(α/2) × (H-h+0.05)* y Detection range width 2 × tan(β/2) × (H-h+0.05)* The detection area depends on the device's field of view angle, installation height, and target height. The following figure uses the horizontal field of view angle, an installation height of 3 meters, and a target height of 1.75 meters as an example for illustration.
Example: For a 1.75 m target height, the detection area for each installation height is as follows:

Table 3. Parameter Definition Parameters Description Value H Installation height 2.2 - 6 m If attribute identification is required, refer to the following table for the installation height requirements:Attribute Identification Installation height Children&Adult Differentiation 2.2 - 4m Gender Recognition 2.2 - 4m Staff Detection 2.2 - 4m Group Counting 2.2 - 6 m View Direction Detection 2.2 - 4m h Target height Example 1.7 m α Horizontal field of view angle of each device 101° β Vertical field of view angle of each device 70° x Detection range length of each device x = 2 × tan(α/2) × (H-h+0.05) for each device y Detection range width of each device y = 2 × tan(β/2) × (H-h+0.05) for each device a Number of devices required along the coverage length Coverage length ÷ x, Round to the nearest integer based on deployment requirements b Number of devices required along the coverage width Coverage width ÷ y, Round to the nearest integer based on deployment requirements Example: For a 6 m × 3 m (length × width) coverage area, with the devices installed at a height of 3 m (H) and a target height of 1.75 m (h):x = 3.16 m, a: Coverage length ÷ x = 6 ÷ 3.16 ≈ 1.90 ≈ 2 devices
y = 1.82 m, b: Coverage width ÷ y = 3 ÷ 1.82 ≈ 1.65 ≈ 2 devices
Conclusion: 2 × 2 = 4 devices are required for complete coverage of the 6 m*3 m area.
