CC5MPX Digital Camera
56
ceiling fan that was off the CC5MPX motion detection would be triggered if the
fan was turned on. After a period of 20 seconds the motion detection would no
longer be triggered as the continuous motion of the fan would automatically
increase the required motion detection trigger level.
The sensitivity level for motion detection is the only user configurable parameter
for Motion Detection operation. A value of 1 provides the least sensitive motion
detect threshold setting and a value of 99 provides the most sensitive motion detect
threshold setting. Motion detection can be a complicated feature to implement. It is
recommended to start off with a motion detect threshold setting of 50 and
experiment with the performance based on your application.
If the camera is not detecting motion that is desired, then the motion detection
sensitivity level should be increased. If the camera is producing too many false
triggers, then the motion detect level should be decreased. Note that there is always
a probability that the camera can either produce false motion detects or not detect
desirable motion due to too many scene variables. In some cases where motion
detection of a small object is required, it may be necessary to set a motion detect
level that will also produce frequent false triggers.
The adaptive motion detect is a very good method for most applications. One
consideration is that when a continuous level of motion is introduced into a scene
the motion detection sensitivity decreases. The result is that some motion may not
be detected when a continuous dynamic scene exists. For example, a person
walking through a scene with windblown trees may not trigger the motion detect
capture that would normally be triggered when there is no wind and the trees are
not moving.
Motion Detection Notes:
x If a moving object that requires detection occupies a larger percentage of
the image scene, the motion detection tends to be more reliable. Zooming
in or moving the camera closer to the moving objects helps improve
performance.
x Objects moving slowly within the image scene require a higher sensitivity
setting compared to fast moving objects.
x Sudden changing light levels can falsely trigger motion detection. Sources
of false triggers include rapidly changing light levels at sunrise or sunset,
or during the movement of clouds.
x Good lighting of the image scene produces the best results.
x The motion detection feature uses the full 4:3 ratio frame to capture
motion. Still images in the 320 x 176, 640 x 352 and 1280 x 720 formats,
and video in the 720p format will crop a portion of the top and bottom of
the image or video.
x Motion detection is paused when video is being recorded.
x The delay from motion occurring to image capture is typically 1 second (2
seconds for a 5MP image).
7.7.5.2 Motion Detection Video Pre-Recording
Video pre-recording allows the camera to record up tp 30 seconds of video leading
up to a related trigger event. This feature can only be used with the external trigger
and motion detection capture events.
The Motion Detection configuration page includes an option labeled Pre-Record
In Seconds. By entering a value between 1 and 30 in this field, the CC5MPX will
begin buffering video in its internal memory. When an event occurs, the CC5MPX
stores a set number of seconds of video to file and then continues recording the live
video until the number of seconds of duration has elapsed.
