o Number Increment
A unique number is appended to each file name. When the Number
Increment is selected an additional box will allow a starting number to
be entered. An example of a file name with the count type is:
Video1_0000001994.avi
o Date and Time
Each file name will have a time stamp appended to it. An example of
a file name with the Date and Time option is:
Video1_2011_01_28_14_22_10.avi
Video1_YYYY_MM_DD_HH_MM_SS.avi
• Resolution/Compression
Currently there are two options for the video capture format. Both options
encode the video using MPEG4. The options are 1280x720 (720P) or
320x240.
• Frame Rate
There are three frame rate options of 30, 15 and 7.5 FPS (Frames Per
Second). Lower frame rates can reduce the file sizes.
The video resolution and frame rate are the two factors that determine the file
size for video files. TABLE 7-3 shows the approximate files size for every
second of recorded video. The largest file sizes are produced by the 720P
30FPS video, which is 500 kbytes per second of video. The smallest video
files are produced by the 320x240 7.5 FPS video which is 9 kbytes per second
of video.

7.6 Image Capture
Selecting the Image Capture tab will bring up the Image Capture Settings page
(see FIGURE 7-26). The image capture settings are the most significant
settings in determining how the camera will operate.
There are five sub tabs that include:
• Power Modes
• Self Timed Capture1
• Self Timed Capture2
