Client Settings

The following functions can be configured in Client Settings.

1. Display profile: Shows the profile currently being used. There are 3 default profiles: profile01, profile02,

and profile03. Each profile refers to one independent video stream with a unique codecs, resolution, frame

rate (FPS), and video quality. If you need to, you can create additional profiles, but keep in mind that more

profiles mean more video streams. Enabling too many video streams could reduce the frame rate and

overall video performance of each stream. For configuring the profile, go to System

Configuration/profile.

2. Media options: Some VPort IP cameras support a line-in or microphone audio input. In this case, you can

select from the following options: Video/Audio, Video Only, Audio Only.

3. Protocol Options: Choose one of four protocols to optimize your usage—Multicast (RTSP or Push) or

Unicast (UDP, TCP, HTTP).

• Multicast Protocol can be used to send a single video stream to multiple clients. In this case, a lot of

bandwidth can be saved since only one video stream is transmitted over the network. However, the

network gateway (e.g., a switch) must support the multicast protocol (e.g., IGMP snooping). Otherwise,

the multicast video transmission will not be successful.

 RTSP: Enable the multicast video stream to be sent using RTSP control, which means the multicast

video stream will be sent only if it receives the client’s request.

 Push: Enable the multicast video stream to be sent using Push control, which means that after this

setting is selected, the multicast video stream will be sent continuously even without any client

requests.

• Unicast Protocol is used to send a single video stream to one client.

 UDP can be used to produce audio and video streams that are more real-time. However, some

packets may be lost due to network burst traffic, and images may become blurred.

 TCP can be used to prevent packet loss, which results in a more accurate video display. The

downside of using TCP is that the real-time delay is worse than with UDP protocol.

 HTTP can be used to prevent being blocked by a router’s firewall. The downside of using HTTP is that

the real-time delay is worse than with UDP protocol.

• Network Interface designates the connection interface for multicast video streams selection. The box

lists the current NIC interfaces. Select which NIC interface will receive multicast streams.

Once the IP camera is connected successfully, Protocol Options will indicate the selected protocol. The

selected protocol will be stored on the user’s PC, and will be used for the next connection.
