By taking reference frames and applying them to refreshed frames, Smart Codec eliminates
the need to transmit data for an unchanged image or parts of the image where there is no
movement. Used together with H.264, Smart Codec can lead to storage savings of up to 60
percent and bandwidth savings of up to 40 percent over H.264 alone.
Note
If Smart Codec is set to ON, video analytics will be unavailable.
Resolution
You can select from multiple resolutions from the drop-down list. The recommended bit
stream value is different for each resolution.
Frame Rate (FPS)
In the Frame Rate (FPS) box, select a frame rate within the available range (1–60 fps for
NTSC cameras; 1–50 fps for PAL cameras).
Note
The frame rate range may vary according to different camera
models.
Bit Rate Type
In the Bit Rate Type box, select CBR or VBR.
CBR
Constant bit rate. The bit rate remains constant (recommended for low-bandwidth
environments). Required if MJPEG compression is used.
VBR
Variable bit rate. The bit rate changes according to the complexity of the scene. Select a
Quality level between 1 (lowest quality) and 6 (highest quality).
In the Bit Rate box, select a bit rate from the list using the Reference Bit Rate as a guide.
I-Frame Interval
In the I-Frame Interval box, set the number of P-frames between I-frames. The value ranges
from 30 to 150. The default value is 60.
The recommended value for I Frame Interval is 2 times the frame rate setting.
Watermark Settings
Click to enable Watermark Settings and then type the watermark text. This function allows you
to verify that the video has not been altered. The default watermark text is DigitalCCTV. The
maximum length is 85 digits. Only numbers, letters, and the underscore character ( _ ) can be
used.
