Recording Frames Per Second
The user can set the recording frames per second from 1 fps to 30 fps for each camera. The actual
captured fps may be different from the chosen camera based on the resolution and model DVR
you have.
Captured Frames Per Second
The captured frames per seconds display box shows the actual fps captured for the selected cam-
era. This may be different from the fps in the camera’s recording frames per second due to the
resolution setting of the camera and model DVR you have.
Network Frames Per Second
Network frames per second allows the user to limit the fps that transmit over the network. Other
DVR’s can only limit the entire system’s transmission. This causes all cameras to transmit at
the same slow speed. The Crest CDVS-7000 series fixes this problem by allowing individual
cameras to transmit at different speeds. This means that if you have an important camera to view
over the network you can increase just this camera’s speed with little or no effect on the networks
bandwidth. To use this feature simply enter the number of frames for each camera to transmit
across the network. Remember you can use the copy to all or the copy to selected to help set the
network fps (see section on these features in the beginning of this chapter).
Recording Quality
The user can set the recording quality for each channel independently. The following recording
quality levels are available:
HIGH: This is the best image quality, but data size is large and will result in fewer days
recording
MIDDLE: This is the default quality level and is a good compromise between quality and
days recording.
LOW: Poor image quality, but data size is very small.
Camera Name
The system allows the user to name each channel of video. To use this feature, highlight the cam-
era name and type a new name. The new name will show on the live and playback screens. The
new name will also be shown in the snapshot text file.
Note: Changes to the name will not affect
video that has already been recorded to the hard disk.
Audio/Camera Setup
Use this feature when connecting microphones to your system. Setting each audio channel to a
specific camera allows the user to hear live and recorded audio. By selecting the camera chan-
nel from the live or playback screen, the user is able to hear audio. One camera channel can be
linked to only one audio channel. Note: The number of audio channels you have depends on
the model of your DVR.
