Thermal Presence Detector User Manual
20
It means that the stream is compressed and transmitted at a comparatively fixed bitrate. The
compression speed is fast, but mosaic may occur on the image.
Variable Bitrate
It means that the device automatically adjust 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.
8.1.5 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 higher bandwidth.
8.1.6 Frame Rate
The frame rate is to describe the frequency at which the video stream is updated and it is
measured by 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 higher frame rate requires higher bandwidth and larger
storage space.
8.1.7 Video Encoding
It stands for the compression standard the device adopts for video encoding.
Note
Available compression standards vary according to device models.
H.264
H.264, also known as MPEG-4 Part 10, Advanced Video Coding, is a compression standard.
Without compressing image quality, it increases compression ratio and reduces the size of video
file than MJPEG or MPEG-4 Part 2.
H.265
H.265, also known as High Efficiency Video Coding (HEVC) and MPEG-H Part 2, is a compression
standard. In comparison to H.264, it offers better video compression at the same resolution, frame
rate and image quality.
MJPEG
Motion JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding
