Image Size
The unit supports both JPEG and MPEG-4 compression for high quality recording and image
display. Images recorded using the standard recording settings are stored in JPEG format. The
settings applied to these images are congurable.
The image size has two congurable parameters, File Size and Image Resolution.
The le size setting can be congured between 5 to 45 KB. This determines the size of the images
that will be stored on the hard drive. A larger le size allows more detail to be included in the
recorded video and provides higher picture quality, however this also means that the hard disk will
be lled faster and images will be overwritten sooner.
The image resolution setting has been included to allow the most appropriate image resolution to be
congured in line with the selected le size. The image resolution is the number of pixels captured
in each image. To Edit the JPEG image resolution highlight Edit to display the JPEG Image size
screen.
Note:
When the High, Medium or Low options are highlighted the screen will display information
on where the JPEG image alias is used, i.e. JPEG proles 1 to 12.

Size

are produced which t the customer and storage requirements for the system.
