What is TTL?

It’s the abbreviation of Time to live. If data is sent out from the encoder via network and all of

the packets are alive permanently on the network, it will cause the big network load. TTL helps

to reduce the network load by controlling the time of staying on network. For example, if you

set the TTL as 50, the data will be deleted after passing by 50 routers.

Packet Size

Select the packet size you want. You should consider the proper packet size according to your

network bandwidth. If your network allows you enough bandwidth for the product connection,

you can set higher size. The factory default is 1500 bytes.

Session name

Type the session name. The allowed range for the session name is 64 characters with

alphabets, Arabic numbers, and underscore (_).

Session information

Type the session information you want to display.

Session Description

Type the session description for more detailed information.

Include audio stream

Check this box if you want to include the audio stream as well as video stream. For your

information, video stream is the fundamental stream whenever you request the RTSP stream

as a factory default.

Include meta data

Meta data contains the motion detection and VCA (video contents analysis) data. Check this

box if you want to include the meta stream as well as video stream. For your information,

video stream is the fundamental stream whenever you request the RTSP stream as a factory

default.

Note

Refer to the ‘EAD-series Media Data Manual.pdf’ for analyzing the stream of video,

audio or meta data.

Enable QoS

By enabling the Quality of Service (QoS) feature, you can specify priority level of network

traffic for video, audio, and metadata (motion detection and VCA). For each traffic type,

determine the DSCP (Differentiated Services Codepoint) value, which represents a QoS class in

the Differentiated Services (DiffServe) model. For the details about the DiffServ standard, refer

to RFC2474 and RFC2475.

It is same as the configuration of multicast stream except for the items below.

Only for multicast system: IP Address, Port, and TTL.

1 2 ... 50 51 52 53 54 55 56 57 58 59 60 ... 95 96
