plug-in that is provided by Network Camera. This plug-in has been registered for certificate and is used to

setting the client parameters in the browser. Users may click on

to install the plug-in. If the web

browser does not allow the user to install, check the Internet security option to lower security levels or

contact network supervisors.

There are two settings for the client side. One is “Media Option”. You can mute the audio by checking

this option. The other is “Protocol Option”. You can choose the connection protocol between client and

server by this option. There are three protocols - UDP, TCP and HTTP. When you choose UDP protocol,

audio and video streams can be more real-time. But some packets may be lost and decoding error will

happen. If you select TCP protocol, packet loss isn’t occurred and decoder will run normally. But the

real-time issue is worse than UDP protocol. If your environment is behind the firewall and it opens HTTP

port (80) only, you can select HTTP protocol only. In this mode, audio will not be sent and you just can

see the video only. If you don’t know which protocol you should choose, select the UDP protocol and the

client will try these protocols in this order, UDP → TCP → HTTP. After the client connects to the

Network Camera successfully, “Protocol Option” will be set as the working protocol automatically.
