1 Sensor Setting Capture mode
User can select sensor capture mode between 1920x1080(2MP) and NTSC/PAL (Some models are xed to NTSC or PAL).
2 Stream 1 Setting
Codec
The codec supported in Stream 1 is H.264 and H.265. There are 3 pre-programmed stream proles available for quick set-up.
Choose the form of video encoding you wish to use from the drop-down list:
• H.264 High Prole
Primary prole for broadcast and disc storage applications, particularly for high-denition television applications (for example,
this is the prole adopted by the Blu-ray Disc storage format and the DVB HDTV broadcast service).
• H.264/H.265 Main Prole
Primary prole for low-cost applications that require additional error robustness, this prole is used rarely in videoconferencing
and mobile applications; it does add additional error resilience tools to the Constrained Baseline Prole. The importance of this
prole is fading after the Constrained Baseline Prole has been dened.
• H.264 Baseline Prole:
Originally intended as the mainstream consumer prole for broadcast and storage applications, the importance of this prole
faded when the High Prole was developed for those applications.
Resolution
This enables users to determine a basic screen size when having an access through the Web Browser or PC program. The screen
size control comes in several modes. Users can change the selected screen size anytime while monitoring the screen on a real-
time basis.
Bitrate control
The bit rate can be set as Constrained Bit Rate (CBR) or Constrained Variable Bit Rate (CVBR). Limiting the maximum bit rate
helps control the bandwidth used by the H.264 or H.265 video stream. Leaving the Maximum bit rate as unlimited maintains
consistently good image quality but increases bandwidth usage when there is more activity in the image. Limiting the bit rate
to a dened value prevents excessive bandwidth usage, but images are degraded when the limit is exceeded.
• CBR: Constrained bitrate.
• CVBR: VBR with maximum bitrate which is set in Bitrate.
• Bitrate: Maximum bitrate for CBR in the range of 100kbps ~10Mbps.
Frame rate
Upon the real-time play, users should select a frame refresh rate per second. If the rate is high, the image will become smooth.
On the other hand, if the rate is low, the image will not be natural but it can reduce a network load.
GOP size
Select the GOP (Group of Picture) size. If users want to have a high quality of fast image one by one, please decrease the value.
For the purpose of general monitoring, please do not change a basic value. Such act may cause a problem to the system
performance.
3 Stream 2 Setting
Sometimes the image size is large due to low light or complex scenery. Adjusting the frame rate and quality helps to control
the bandwidth and storage used by the Motion JPEG video stream in these situations. Limiting the frame rate and quality
optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage,
the Resolution, Frame rate, and Frame Quality should be set to an optimal value.
• MJPEG Resolution:
Same as the stream 1 setting.
• MJPEG Frame rate:
Same as the stream 1 setting.
• MJPEG Quality:
Select the picture quality. If users want to have a high quality of fast image one by one, please decrease the value. For the
purpose of general monitoring, please do not change a basic value. Such act may cause a problem to the system performance.
