Using lower frame rates
Frame rate and resolution. Units can record up to 30 ips from each NTSC camera (up to 25 ips for
PAL), at the default resolution. Setting a higher resolution may require lowering the frame-rate.
Slower fast-forward or rewind. More ips take more time to process. If recording rates of one or two
images per second are satisfactory; then use them.
Security video and commercial video. The movement of persons recorded at higher rates appear
smoother; however, consult your security personnel about what they need from video surveillance.
Two or three frames per second may be wholly adequate for some security needs.
Quality Setting
On the Recording tab, click a cell in the Quality column. Select a value (a compression factor) from
the list that appears. The values range from: 6 to 10. The default value is: 7.

artifacts in the video. The highest setting can double the use of storage.
