3.1 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 20K 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.
