INDOOR INSTALLATIONS
Please follow the instructions below for indoor camera installations:
1.
Decide on a standard recognition position. Where will the camera be installed, and where
must objects be detected? Installing the camera so objects pass through the centre of the
field of view is recommended.
2.
Install the camera at an appropriate height for object recognition. For example, a camera
with f=2.8mm lens installed on an indoor ceiling at a height of 2.7m would most accurately
detect objects between 7.5-8m from the camera.
3.
Install the camera at an appropriate angle for object recognition. This is critical for accurate
object detection. The camera should be installed at an angle that meets the centre of the
desired object when it would be the optimal distance away. For example, for a camera with
f=2.8mm lens installed on an indoor ceiling at a height of 2.7m would have an accurate
detection zone at 7.5-8m away from the camera. The corresponding ideal installation angle
would be 70°.
If there is limited space in the installation environment—for example, if less than 4m is
available between the camera and target object range—the installation angle can be
adjusted to a more severe angle. However, as the angle reaches 0-30° the ability to
accurately apply tracking rule types decreases.
4.
For deep learning rules that depend upon object tracking in addition to detection, the total
range of object movement should be considered.
