Example: Recording file size for 1 hour @ quality level 1 with resolution D1 will be:
60 minutes * 60 seconds = 3600 seconds
3600 seconds*2048Kbps/8/1024=900MB
Note:
The streaming bandwidth can vary considerably according to the level of variations in the image. Static images are more efficiently
compressed than dynamic ones. The values above are for reference only.
Frame rates are assumed to be set to maximum which is 25fps for PAL and 30fps for NTSC.
PAL: D1 (704*576), HD1 (704*288), and CIF (352*288),
NTSC: D1 (704*480), HD1 (704*240) and CIF (352*240)
