3.19.5. Count target zone (Gate) configurations
Each target zone has its own configuration and has to be saved individually. The Gate menu specifies which target
zone is currently selected. The Count target zone not only detects the motion, but also detects the direction of the motion.
The Count target zone is shown as a green arrow with a red number in the middle. The number signifies the amount of
detected motions moving in this direction. To switch between the target zones, click the desired target zone arrow in
the live view screen.

1. Define the target zones in the live view screen on the left. Up to 3 target zones (Gates) can be configured.
a. Place the mouse cursor at the start point over the live-mode camera view on the left
b. Hold down the left mouse button and drag the cursor to draw the rectangular target zone
c. Let the mouse button go
d. Adjust or move the created target area if necessary
2. Name the specified Gate. In this example, Gate No. 1 is labeled as "Gate1"
3. Set the Background Refresh Time (1s - 1800s). Same as Surveillance target zone (Area).
4. Configure Detection Size (10p - 100p). Same as Surveillance target zone (Area).
5. Configure Detection Sensitivity (10% - 97%). Same as Surveillance target zone (Area).
6. Configure Object Speed (20p - 300p). The Object Speed value determines the speed at which the object has
to be moving in order to be counted by the Count option.
Object Speed:
When motion occurs on the screen, ELMO DVR analyzes consecutive frames, in which motion has occurred, and decides
whether the occurred motion(s) represents one same object.
whether the occurred motion(s) represents one same object.
The only way this could be determined is by the speed with which the object moves across the screen. In the diagram
on the left, two consecutive frames are analyzed. The distance that the object has traveled between two consecutive
frames equals d.

In order to be counted as a single object, the distance that the object travels between 2 frames has to be smaller
than the Object Speed parameter value. If the distance traveled exceeds the Object Speed, the motion
