6.2 Recording time
Approximate recording times in hours without audio
when recording with a 160-GB hard disk.
Reference:
24H=1 day, 168H=1 week, 720H=1 month,
8760H=1year
(Estimated with typical image-low noise level)
When audio is recorded you must calculate an
approximate file size of 18KB (PAL) or 21.6KB (NTSC)
per second of audio. This can reduce the recording
times, especially for the lower recording rates, given in
the above tables significantly.
