OUTDOOR INSTALLATIONS
Please follow the additional criteria below for outdoor camera installations:
1. Install the camera at an appropriate angle for object recognition. This is critical for
accurate object detection outdoors. For example, a camera with f=2.8mm lens installed
on a utility pole at a height of 7.5m should be adjusted at about 50° to match the
centre point of objects 8-8.5m away. Accuracy will decrease as the installation angle
decreases.
2. The maximum object recognition distance is obtained when the camera is almost
horizontal (installation angle close to 90°). For example, a camera with a f=3.3mm lens
would be able to detect people up to 55m and vehicles up to 80m.
3. Vehicle detection also follows the recommended installation angle/height range. For
example, refer to the scene below:
Detecting vehicles at greater heights can best be achieved as follows:
