IVS Best Practices

The installation site and installation type are essential to the final performance, this section introduces how to select a proper installation site and installation type

Suitable Sites

The sites need to provide a large visual field and be open and simple. There should be no frequently moving objects or drastic changes in lighting condition.

These kind of sites are suitable for cross detection at borderlines, communities, lawns, railways, and highways, access detection at underground garages, pedestrian streets, fall detection at lakes, and access detection at rooftops and private properties


Unsuitable Sites

Installation Requirements

The shorter the installation distance is, the smaller the arm width will be

The maximum arm width for humans is 12m

Fixed Lens installation distance reference table:

Lens' focal length (mm) 2.8 3.6 6.0 8.0 12 30
Installing distance (m) 6 8 13 17 26 65

Varifocal Lens installation distance reference:

  • When the install distance is 5m~22 m, it is recommended to select the lens which focal length is 2.7mm~13.5 mm.
  • When the installing distance is 13m~55m, it is recommended to select the lens which focal length is 7mm~35mm
  • Recommended installing height: h > 3m and the maximum height varies with different lens
  • Recommended installation angle: 0° ~ 45° (elevation angle)
  • Recommended lens: Low focal length and large angle of view
