human, vehicle, animal, and others. Only targets whose size is between the Max. Size and Min. Size
values will trigger the alarm.
You can draw the max size and min size rectangles according to a real target in the
scene. The recommended size is 1.2 times of the target.
• Due to the main difference between humans and animals is height, just consider the animal height.

Detection Parameters
• Detection Sensitivity: The higher the sensitivity, the easier the target will be detected.
• Background Update Rate: If a detected target remains in the monitoring scene for a certain time, the
system will consider the target as the background automatically. The greater the value, the quicker
the target will be counted as the background.
• Minimum Target Size: The system will filter out objects smaller than the minimum target size.
• Displacement Constraint for Target Generation: The higher the value, the slower the target is
generated, and the higher the accuracy.
• Optical-Axis Movement: Check this function when the target moves in the direction of the camera’s
optical axis. When the target is far from the device and the movement is not clear, enable this function
to check the movement direction.
• Single Alarm: The system sends an alarm only once for each target triggering. Otherwise, the alarm will
trigger continuously until the target disappears.
• Scene Modes: The scene mode is set to be General by default. Select Distant View when you are far
from the targets. Select Indoor when you are indoors.
