Pedestrians or vehicles that stay for too long would be regarded as abandoned objects. To filter out
such alarms, you can use Target filter. In addition, the duration can be properly extended to avoid
false alarm due to a short stay of people.
Applicable scenes: Scenes with sparse targets, no obvious and frequent light changes. For scenes with
intensive targets or too many obstacles, missed alarms would increase; for scenes in which too many
people stay, false alarms would increase. Select detection areas with simple texture, because this
function is not applicable to scenes with complex texture.
Step 1 Select Abandoned Object from the Rule Type list.
