OPTIMISING CAMERA INSTALLATION
The accuracy of a deep learning-based installation will heavily depend upon various
environmental and installation factors. The following guidelines are recommended for the best
performance (>95% accuracy):
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.
5. For deep learning rules that depend upon object tracking in addition to detection, the
total range of object movement should be considered.
