when you are playing back images, the system will continue recording.
When the record LED on the Hard drive is on, this indicates that recording is taking place.

Update Rates

This table gives an indication of the overall update rate in images per second that will apply for different
Image Retention settings (see section 10.4.3.1.1) and hard drive capacities assuming an average image
size of 18K bytes. Note that if the average image size is lower, update rates will be higher; if the average
image size is higher, update rates will lower.
To get the update rate per camera, divide the overall update rate by the number of cameras.

Note that 24-hour mode operation on a conventional VCR time-lapse recorder is about 5
second. The shaded cells in this table show where the update rate will be equal to or better than a VCR in
24-hour mode.
