Prior to installing and configuring the Motion Direction Analysis plug-in you should ensure that the location where you plan to perform Motion Direction Analysis meets the following specifications:
Cameras
Motion Direction Analysis is possible with both analog and IP cameras at any resolution. Motion Direction Analysis cannot be performed with PTZ cameras. Dynamic gain compensation should be set to the lowest level. Use wide dynamic range cameras for outdoor lighting situations.
Lighting
Uniform lighting is ideal. Back lighting (bright conditions) will negatively affect performance. Changes in lighting conditions throughout the day should be considered.
Field of View
The camera’s field of view (FOV) should be as wide as possible, at least twice as wide as the objects being observed.
An example of the acceptable FOV for Motion Direction Analysis of people and vehicles is shown.
...
Mounting
Cameras can be mounted above or to the side of the objects being tracked. Cameras should be rigidly mounted to minimize shaking or swaying.
