The areas that you want to monitor in a cameras view are configured in the Camera Alarm

camera view that you want monitored, you need to draw on the window. Use the drawing tools to
draw on the Camera Alarm Configuration window.
The status of each Video Intelligence alarm is highlighted in the Status field. There are three alarm
states:
• Red - Alarm is disabled. The alarm can be disabled via the Enabled option button.
• Yellow - Alarm is enabled, however, the recording mode set for the camera does NOT
support alarms so the alarms will not be generated. Supported modes are Only Record
on Alarm or Recording Always with Alarm On.
• Green - Alarm is enabled and a supported recording mode is selected. Alarms will be
generated.

Video Intelligence Best Practices
To ensure you get the highest quality results when using Video Intelligence on the NVR, it is
recommended that you adhere to the following:
• An object exhibiting movement or a change in the scene background must be large
enough to be detected, i.e. it must be around 1/25 of the image size.
• The color of the object (in grayscale) should be approximately 10-15% different than the
background.
• The frame rate of the video should be high enough to capture the object in one or more
captured frames.
