MOTION SPEED MENU
Figure 6. Motion Speed Menu
1 MOTION Button – Opens the motion speed menu. Use this menu to set motion detection and pre-alarm recording speeds.
2 Motion Recording Speed Slider Bar – Sets the recording rate for motion detection.
3 Pre-alarm Function Slider Bar – Programs the pre-alarm function for individual cameras. When motion is detected, images
are recorded for the programmed duration (five seconds maximum per camera) before the event happened.
To the right of the A (average) bar is a slider that sets the pre-alarm function for all cameras.
How can the DX7100 record video before motion occurs? Video is recorded for the amount of pre-alarm time, five seconds
for example, but as long as there is no motion, the five seconds of video is constantly overwritten with the latest five
seconds. When motion is detected, the DX7100 stops overwriting the video.
