1. The recording speed is expressed in fractions. 1/ 1 is to record at the full recording
speed, which you set in RESOLUTION. 1 / 2 is to record at half of the recording
speed. 1 /3 is to record at one third of the recording speed. You can set up the
parameter from 1/1, 1/2, 1/3, 1/4,… to 1/999.
2. By lowering the recording speed, the DVR records less frames but gains a longer
recording duration. If you set the DVR’s recording speed at 1/2, the recording duration
will be two times longer. 1/3 will make the recording duration three times longer, and
so on.
3. When the RESOLUTION is set to QUAD Mode, the selection of the recording speed
is limited to 1/1, 1/2, and 1/3.
4. All active cameras share the recording speed. To turn off the recording on a specific
channel, please refer to [SYSTEM MENU]f[CONFIGURATION]f[CAMERA SETUP]
f[CAMERA ACTIVE SETUP]. Please note that channels with video loss are still
active and recording. In other words, those channels are still sharing the recording
