NOTE:
The following settings on the Camera Settings page are not available on RTSP interfaces, and they vary on ONVIF
and certain proprietary interfaces.
8.
The Video Settings sliders allow you to adjust the image as it is displayed on your screen.
9.
The Format section allows you to select the compression format.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. See the following section, “Motion Masks, Video Masks, and Motion Windows” for more information about
those portions of the Camera Settings page.
