4.1.2 Video Type
Select the content (video and audio) that should be contained in the stream.
Video
Only video content is contained in the stream.
Video & Audio
Video content and audio content are contained in the composite stream.
4.1.3 Resolution
Select video resolution according to actual needs. Higher resolution requires higher bandwidth and
storage.
4.1.4 Bitrate Type and Max. Bitrate
Constant Bitrate
It means that the stream is compressed and transmitted at a comparatively fixed bitrate. The compression
speed is fast, but a mosaic effect may occur on the image.
Variable Bitrate
The device automatically adjusts the bitrate under the set
Max. Bitrate
. The compression speed is slower
than that of the constant bitrate, but it guarantees the image quality of complex scenes.
4.1.5 Video Quality
When Bitrate Type is set as Variable , video quality is configurable. Select a video quality according to
actual needs. Note that higher video quality requires more bandwidth.
4.1.6 Frame Rate
The frame rate describes the frequency at which the video stream is updated and it is measured in frames
per second (fps).
A higher frame rate is advantageous when there is movement in the video stream, as it maintains image
quality throughout. Note that a higher frame rate requires more bandwidth and storage space.
4.1.7 Video Encoding
The compression standard the device adopts for video encoding.
NOTE:
Available compression standards vary by model.
•
H.264
H.264, also known as MPEG-4 Part 10, Advanced Video Coding, is a compression standard. Without
compromising image quality, it increases the compression ratio and reduces the video file size more
than MJPEG or MPEG-4 Part 2.
• H.264+
H.264+ is an improved compression coding technology based on H.264. By enabling H.264+, you can
