For each record type ( General , Motion , Alarm ), you can configure the encoding format,
resolution, frame rate, bit rate, and I-frame interval settings. You can also apply a custom
watermark to the main stream.
Format
In the Format box, select H.264B , H.264 , H.264H , MJPEG , or H.265 .
Smart Codec
Set Smart Codec to ON or OFF .
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.
Resolution
In the Resolution box, select a resolution from the list. The available options differ between
the main stream and sub streams.
Frame Rate
In the Frame Rate (FPS) box, select a frame rate within the available range (1–30 fps for
NTSC cameras; 1–25 fps for PAL cameras).
Bit Rate
In the Bit Rate Type box, select CBR or VBR .
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, enter a value between 1 and 150. The default I-frame interval is
two times the frame rate. For example, if the frame rate is 30 fps, the I-frame interval will be 60.
H.264 Main Profile. Uses less bandwidth than Baseline Profile at the same quality.
H.264B Baseline Profile. Uses up to 50% less bandwidth than MPEG4 and up to 80% less
than MJPEG. Higher compression and lower quality than H.264.
H.264H High Profile. Uses less bandwidth than Main Profile at the same quality. Lower
compression and higher quality than H.264.
MJPEG Uses the most bandwidth but produces excellent image quality with access to
every image in the stream.
H.265 High Efficiency Video Coding. Supports 4K resolution. Twice as efficient as H.264.
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) and 6 (highest).
