Q (Quality)
There are 5 recording quality - Q5/Q4/Q3/Q2/Q1. Recommended quality for event recording is Q3.
Max R/F
Max R/F shows the number of frame available according to the selected resolution. For instance, if it is
set by 30fps at CIF, it means that the channel can record up to 30frame at CIF resolution.
Reference: how to calculate recording performance
4CIF[704x480] = 2 x CIF[704x240] = 4 x CIF[352x240]
If 400 frame can be recorded at CIF resolution, it is possible to record 200 frames at 2CIF
and 100 frames at 4CIF resolution is possible.
In case that the channel is configured as disable
Configuration method: Menu > camera configuration > channel: “Disable” – (the channel in
gray)
For example, all channels can be configured as 30fps at CIF all the same. If one channel is
configured as disable, system has resource available as much as 30fps at CIF. And if combining
it with other 30fps at CIF, other channel can be configured as 30fps at 2CIF.
In case that the channel is configured as 0 fps.
Another channel cannot use resource room as much as CIF 30fps. It is because the channel
configured as 0 fps needs 2~3fps at least for network.
Reference: the relation in between general recording and event recording.
When Event is triggered, records event recording according to the configured value. Recording
Performance of DVR depends on the product. For example, if OSD-1600 is set as manual recording at
CIF 400fps and event recording at CIF 400fps, it cannot be over CIF 400fps. Therefore, it should be
configured within CIF at 400fps resource.
Event configuration value on CIF 400fps
If you configure recording all channels at CIF 30fps, available event recording configuration is
CIF 30fps, 2CIF 15fps, 4CIF 7 fps.
If you want to configure channel no.1 as 4CIF 30fps, you should adjust the other channel
recording configuration.
On event recording of multi channel
With multiple channel event recording, if configured recording value is over the system max
performance, general recording will keep their recording configuration and event recording will
be balanced down equally.
