Recording Options
This item takes you to another screen that allows you to access the options that
relate to the recording quality. Use the arrows and SEL buttons to select the items
as desired. The recording quality of the Digital BUS-WATCH® has three
independent settings: REC MODE, REC FPS, and REC QUALITY.
• REC MODE: Can be set to either FRAME or FIELD. This sets whether the unit is
recording video fields, or full frames. Frames require more disk-space per image,
so they reduce recording time but provide a better quality image. Fields reduce
video quality but increase recording time.
• REC FPS: Has several different options, ranging from 0.5P to 60P. The number
equates to fields or frames per second. For real-time video with accompanying
audio, this must be set to 60P. At any setting less than 60P, the audio recording
does not function.
• REC QUALITY: This setting corresponds to the compression ratio of the video
data. There are three options: HIGH, NORMAL, and LOW. HIGH gives the best
quality image but reduces the length of recording time. LOW gives the longest
recording time, but the recorded image quality is reduced slightly.
These three settings all have an significant effect on recording capacity of a given hard
drive. Below is a chart giving the approximate recording capacity of a 20GB drive at
each of the above settings. Drives of larger sizes have proportionally larger recording
capacities.
