Operation Manual

In a tunnel installation, an operator wants to observe traffic flow. If a car enters a tunnel through an exit, an alarm alerts the operator

to activate the traffic signals to stop all traffic in the tunnel.

In an entrance or exit installation, a camera is pointed at an exit door. If a person tries to enter through the exit door, an alarm triggers.

Ideal Scene Setup for Directional Motion

Install the camera in a ceiling or against a wall with the lens pointing at a slight downward angle, above regular motion activity. The

width of the object you want to detect should be at least one-tenth of the total width of the scene. To achieve increased accuracy in a

crowded scene, set the width of the object to one-sixth of the total width of the scene.

The ideal scene selection for the Directional Motion behavior contains light traffic with all people and objects moving in the same direc-

tion, minimal obstructions, and a clean background; however, the behavior can be used in settings that do not meet all of these require-

ments. If heavy traffic or a busy background is unavoidable, place zones in a relatively stable areas.

Avoid crowded scenes in which people move in all directions or stand in one place for long periods of time.

Loitering Detection

The Loitering Detection behavior identifies when people or vehicles remain in a defined zone longer than the user-defined time allows.

This behavior is effective in real-time notification of suspicious behavior around ATMs, stairwells, and school grounds.

Ideal Scene Setup for Loitering Detection

Install the camera in a ceiling or against a wall with the lens pointing at a slight downward angle, above regular motion activity.

The ideal scene for Loitering Detection behavior is one with light traffic and a clean background. If heavy traffic or a busy background is

unavoidable, place the user-defined zone in a relatively stable area.

Avoid crowded scenes where people move in all directions or stand in one place for long periods of time.

Object Counting

The Object Counting behavior counts the number of objects that enter a user-defined zone. This behavior can be used to count people at

a store entrance/exit or inside a store where the traffic is light. It might also be used to monitor vehicle traffic on highways, local streets

and roads, parking lots, and garages.

Ideal Scene for Object Counting

If you plan to detect people, install the camera pointing downward (vertically) above regular motion activity. If you plan to detect vehicles,

install the camera pointing downward at a slight angle above regular motion activity.

The ideal scene for the Object Counting behavior contains light traffic, minimal obstructions, and a clean background. If heavy traffic or

a busy background is unavoidable, place zones (polygon or line) in relatively stable areas.

A one-directional motion scene (for example, a vertical hallway) is preferable. Avoid crowded scenes in which people or objects move

in all directions or remain in place for long periods of time.

Object Removal

The Object Removal analytic behavior triggers an alarm if an object is removed from a user-defined zone. It is ideal for detecting the

removal of high-value objects, such as a painting from a wall or a statue from a pedestal.

Ideal Scene for Object Removal

Install the camera in a high position looking down on the scene. The monitored object should occupy a quarter of the camera scene, and

the field of view should be as wide as possible.
