Perform the following steps to test the motion recording performance of the mask you created:
1. Click the “Save and Test Mask” button.
2. Check the following parameters:
• Max Consecutive: The highest number of consecutive images that exhibited motion during the current test; when motion occurs, a
colored border appears around the video pane.
• Consecutive Frames: The current number of consecutive images that differed enough from the previous image for motion to be
recognized. This resets to zero when a change is not recognized in an image.
• Total: The total number of images that exhibited motion during the test, whether consecutive or nonconsecutive.
• Total Non-Motion Frames: The number of images during the test that did not exhibit motion.
• Total Frames: The total number of images displayed and compared during the test.
After the test, assess whether too much or too little of the image is masked and whether the sensitivity is too high or too low. Also assess the
consecutive images setting. For example, if a person can walk across the entire camera view while only five images are recorded, the
consecutive images setting should be less than five so that such activity is not ignored.
Any changes made on this page for individual cameras are applied when you click Test Mask, even while recording. You cannot change motion
settings for more than one camera at a time.
The Motion tab also contains settings that control the triggering of alarms based on motion events. You can configure a zone of camera inputs to
begin recording when motion occurs on specific cameras (refer to Adding and Configuring Zones on page 30 for more information). The settings
that control when this recording occurs are found in the Alarm Settings area of the Motion tab. The follow settings are available:
• Consecutive Motion Frames to Trigger Alarm: The number of consecutive motion images that must occur on the selected camera
input to activate recording on all cameras in the zone.
• Consecutive Non-Motion Frames for Reset: The number of consecutive non-motion images that must occur to end alarm recording
or to begin post-motion recording, if configured.
You can also configure pre- and post-motion recording on the Motion tab. The following settings are available for the Pre-Motion Recording and
Post-Motion Recording sections of the Motion tab:
• Consecutive Motion Frames to Trigger Pre-Motion Recording: The minimum number of consecutive motion images that must occur
on the selected camera input for the pre-motion video to be inserted at the beginning of the recorded motion event.
• Pre-Recording Seconds: The amount of video inserted at the beginning of the recorded motion event when the minimum number of
consecutive motion images occur. The images included in the pre-motion segment is determined by counting backward from the final
consecutive motion image. The maximum possible Pre-Recording Seconds value is equal to the Maximum Video Buffer setting on the
General tab.
• Consecutive Non-Motion Frames to Start Post Motion Recording: The minimum number of consecutive non-motion images that will
end the motion event and start a post-motion recording period. The first image included in the post-motion recording period is the first
image after the final consecutive non-motion image.
• Post-Recording Seconds: The amount of video recorded in the post-motion recording period. This video is appended to the end of the
recorded motion event. If the minimum number of consecutive motion images reoccurs during the post-recording period, the post-recording
period restarts beginning with the image following the final consecutive motion image.
