Color resolution. Select the required color resolution or color depth (16-bit grayscale
or 24-bit color). Color images typically require more storage space than grayscale
images but have a greater depth color.
Table 2 shows the color resolutions supported.
Camera type. The camera type field is for information only and indicates the type of
model of the camera capture hardware used for this camera channel. This setting is
hardware dependent and is not user configurable.
Camera locations. You must enter the camera distance from the recorder if the camera
is to be specifically and individually located on the map display window. The location of
the camera is specified relative to the recorder’s position with the bearing angle entered
with respect to geographic north. If you use camera locations, you must configure the
site as either fixed-location or mobile.
Compression
Press the Compression button to display the Compression screen ( Figure 34 on page 42).
The compression algorithm refers to the mathematical method or process used to reduce the
size of the original image for recording and storage. The compression level controls the
extent of compression applied. The default compression algorithm used by the MobileView
system is JPEG.
Increasing the compression level reduces the size of the resulting image and extends the
storage capacity of the recording system; however a highly compressed image may suffer
loss of useful image content and may adversely affect the ability to analyze, authenticate,
and identify the content of the image. Reducing the compression level ensures preservation
of image content and quality but increases the size of each stored image and reduces the
storage capacity of the recording system.
Slide the compression slider left to decrease image compression or right to increase image
compression.
