Moxa VPort P06-1MP-M12-CAM42-T [54/83] Vport onvif profile s system configuration

VPort ONVIF Profile S System Configuration

4-37

The video encoder setting supports an Advanced Mode. Click on the Advance Mode button to view the

following configuration options.

Setting Description Default

Bitrate Limit (kbps)

(only for H.264)

The administrator can fix the bandwidth to tune the video

quality and FPS (frames per second) to the optimum

combination. Different resolutions have different

bandwidth parameters. The VPort will tune the video

performance according to the bandwidth. A higher

bandwidth means better quality and higher FPS.

4000

H.264 Key Frame

Interval

Configure the key frame interval of the H.264 stream. A

ow number means higher video quality (due to more key

frames), but more bandwidth will be consumed. If you

have concerns about bandwidth, then select a higher

number for key frame interval.

Multicast Setting

Setting Description Default

IP Address Multicast Group address for sending a video stream. 239.127.0.100

Port Video port number. Videoecnoder01: 5556

Videoencoder02: 5558

Videoencoder03: 5560

Videoencoder04: 5562

TTL Multicast-TTL (Time-to-live) threshold. A certain TTL

threshold is

defined for each network interface or tunnel.

A multicast packet’s TTL must be larger than the defined

TTL for that packet to be forwarded across that link.

128

Session Timeout (sec) Timeout between the client and the stream 15 (seconds)

Multicast Send

Userdata

Configure the video stream with or without userdata Enable

Auto Start Enable/disable the Multicast stream push mode Disable

NOTE

mage quality, FPS, and bandwidth are influenced significantly by network throughput, system network

bandwidth management, applications the VPort runs (such as VMD), how complicated the image is, and the

performance of your PC or notebook when displaying images. The administrator should take into consideration

all of these variables when designing the video over IP system, and when specifying the requirements for the

video system.

different resolution

s, FPS values, and video content.
