Q (Quality)
Indicates the recording quality: Q5, Q4, Q3, Q2, and Q1. For Event Recording, Q3 or higher is
recommended.
Max R/F
Indicates the maximum frame rate available for a selected resolution. For instance, CIF 30fps
means that you can select up to 30fps for the CIF resolution of a selected channel. D1 30fps
means that you can select up to 30fps for the D1 resolution.
How to Calculate Recording Performance
D1 [704x480] = 2 x Half D1 [704x240] = 4 x CIF [352x240]
120 D1 compressed frames = 240 Half D1 compressed frames = 480 CIF
compressed frames
The resolution and maximum frame rate vary depending on the number of enabled channels.
• When disabling a channel in the Channel settings
How to Disable: Select Menu > Camera Settings > Use Channel > Disable. (The channel is then
grayed out to show that it is disabled.) For example, the SVR-1660C can record every channel at up to
CIF 30fps. If a channel is "Disabled" in the Channel settings, there is then a surplus of CIF 30fps
recording capacity. You can use the —surplus CIF (352x240) 30fps to increase another channel's
resolution to Half D1 (704x240) 30fps (remember from above that CIF x 2 = Half D1).
• Setting a channel's frame rate to "0fps" in the Program settings
Surplus CIF 30fps cannot be used to increase another channel's resolution because the 0fps
channel still uses at least 2 to 3 recording frames per second for various reasons
including network communications. You must disable the channel instead of setting it to
0fps if you want to conserve and use the surplus CIF 30fps recording capacity for
another channel.
Relation Between Normal Recording and Event Recording
When an event occurs, Event Recording is activated with the Program settings. DVR
recording performance varies depending on the model. For example, the recording performance
of the SVR-1660C is CIF 480fps for both Normal and Event Recording. When both recording
modes are in effect, its recording performance cannot exceed CIF 480fps. That means that
Event Recording can be set up for the SVR-1660C only if the total of Event and Normal
Recording of all channels does not exceed CIF 480fps.
