Resolution The NVR system supports various resolutions, which you can
select from a dropdown list.
Note The selection is different for each NVR series. The
Performance Series Full PoE Network Video
Recorders can automatically detect a connected 720p
or 1080p camera’s configured resolution (as 720p or
1080p) But you must manually configure the resolution
(960H or below) for analog cameras, and 1080p HQA
cameras that are in SD mode.
Frame Rate PAL: 1 to 25 fps
NTSC: 1 to 30 fps
Bit Rate Type Select either CBR (constant bit rate) or VBR (variable bit rate).
Note If your device is connected to the NVR through ONVIF,
then you can not select VBR. If your device is
connected to the NVR through a private protocol, then
you can select either CBR or VBR.
Bit Rate Main Stream: Select a bit rate to change the video quality.
The larger the bit rate, the better the video quality. We
recommend that you accept the default bit rate. The GUI also
displays the reference bit rate range and frame rate for the
selected resolution.
Extra Stream: In DBR, the bit rate is the maximum value. For
dynamic video, the NVR system will decrease the frame rate
or video quality to maintain the bit rate. The value is null for
VBR mode.
Enable Watermark Allows you to verify that the video has not been tampered.
Watermark String Enter the text for the watermark. The default watermark is
DigitalCCTV. The maximum text length is 85 characters. You
can use only letters, numbers, and an underline.
