Videoswitch VDM Digital Recorder 3 Recording Unless specifically configured otherwise, the system will always be recording images from all cameras. Even 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. RECORD 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 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. Image Retention/ Drive Size 160G 320G 500G 600G 800G 7 Days 15 25 25 25 25 14 Days 7 15 23 25 25 31 Days 3 6.5 10 12.5 17 62 Days 1.7 3.3 5.19 6 8 Note that 24-hour mode operation on a conventional VCR time-lapse recorder is about 5½ images per 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. 3.2 CD Capacity This table gives an indication of the number of minutes of video that can be archived onto a 700Mbyte CD. Note that for integrity of evidence, all cameras are recorded.
