Motion Detection

116 VideoEdge NVR 4.4 Installation and User Manual

• Motion Detection events create entries in the victor site manager database. It is important to

ensure that the motion detection parameters are accurate to avoid generating false entries.

• Exclude the Time Stamp region from motion de

tection, because the time stamp changes

constantly and could register as motion.

• Try not to point cameras into sunlight, becaus

e high brightness will prevent detection of

movement of bright objects such as a person with a white shirt.

• Avoid areas with persistent motion, such as trees, blinking light

s, or spinning signs, by using an

appropriate region of interest.

• Do not use motion detection on moving cameras, su

ch as PTZ cameras, cameras that vibrate

due to wind or other effects, or cameras mounted on moveable fixtures.

Enabling Motion Detection

To enable a camera to use Motion Detection features, you can use the Video List page. Refer to

Procedure 8-1 Editing Basic Video Settings via the Device List on page 93 or the Function and

Stream settings section of the camera Advanced Edit page.

Figure 9-1 Function and Stream Settings

A Stream Configuration is required that allows the NVR to generate meta-data for motion

detection. You also need to select Motion Detection in the Video Analysis field. The NVR will

automatically determine the required stream settings (Table 9-1) and check if the currently

configured streams satisfy those req

irements. If only one stream is configured and it does not

satisfy the requirements for Motion Detection, the NVR will attempt to automatically open the

second stream with settings best suited for Motion Detection. If the camera does not support dual

streaming you will manually need to adjust the configuration of the configured stream.

Motion Detection may not be available on a camera

if it’

s minimum video resolution setting is

higher than the maximum acceptable resolution for Motion Detection. The NVR will not allow you

to configure a camera for Motion Detection if the resolution setting of the camera is higher than the

settings in Table 9-1.
