Camerasare not blocked by objects, such as leaves, to ensure continuous tracking ofthe surveillance object. If cameras are blocked by objects, the surveillanceobjects may not be continuously tracked, increasing the false negative rate.Additionaly, in bad weather conditions, the objects blocking camera lenses mayshake and interfere with motion detection, increasing the false positive rate.
Installation position of a camera to avoid lens blocking
If theinstallation position is near a vibration interference source, such as a largemechanical part or a bridge that is severely shaken, the vibration of theinstallation position causes image shaking. The unstable image causes thefailure to set up a stable background model based on the motion detectionalgorithm. As a result, the detection performance deteriorates sharply.
Thecamera installation position should not directly face the light source, watersurface, or reflection plane. If a camera directly faces a strong light source,the image will appear white. Halo and flare will affect accurate tracking onsurveillance objects. If a camera directly faces reflective surfaces such aswater surface, mirror surface, or glasses, the camera will incorrectly extractmoving objects in the reflection, causing false alarms and interference.
