NOTE: The following settings on the Camera Settings page are not available on RTSP interfaces, and they vary on
ONVIF and certain proprietary interfaces.
7. The Video Settings sliders allow you to adjust the image as it is displayed on your screen.
8. The Format section allows you to select the compression format.
9. The Quality slider allows you to modify the image quality by increasing or decreasing its size. Decreasing
image quality saves disk space by reducing the size of the video that's being recorded.
10. The Pre Motion slider adjusts the number of seconds of video that are saved before the motion event
occurs. For example, suppose Pre Motion is set to 5; when you play back motion video from that camera,
you will see five seconds of video that was recorded before the motion event occurred, followed by the
motion event itself.
11. Post Motion is the same as Pre Motion, except that the slider adjusts the number of seconds of video that
are saved after the motion event has completed.
12. The Sensitivity slider allows you to configure how much motion must occur in the camera's view to trigger
motion recording (if enabled on the Schedule page). A low sensitivity setting can reduce false motion
created by video noise or shadows. If the page includes a Motion Window section (available with certain
IP cameras), you can also change a percentage slider, which determines how much of the camera view
must change to trigger motion recording.
NOTE: See the following section, "Motion Masks, Video Masks, and Motion Windows," for more details.
13. Smooth Begin and Smooth End prevent the undesired recording of certain motion events. Smooth Begin
requires a minimum amount of time for motion to occur before motion recording begins; this prevents
things such as a blinking light of a laser bar code scanner in a dark room, or cars passing on a road in the
distance, from triggering motion recording. Smooth End determines how much video the system
continues recording after the motion is no longer detected; this prevents the recording of choppy
segments of frequent motion video.
NOTE: Smooth Begin and Smooth End are available only on analog cameras.
14. Crop Window, available on certain IP cameras, allows you to crop unimportant portions of a camera
image in order to save disk space. Click Edit and then use the mouse cursor to draw a box on the video
window. This box will be the portion of the camera's view that will be recorded and displayed (the rest of
the view will be ignored). Click Apply to activate the crop; click Edit, Clear, and Apply to deactivate the
crop.
15. The Defaults buttons restore factory settings to their respective sections. One Defaults button restores
the Video Settings, and the other Defaults button restores the Record Settings.
16. See the following section, "Motion Masks, Video Masks, and Motion Windows" for more information
about those portions of the Camera Settings page.
