Client settings
There are four settings for the client side in IE.
1. The first one is “
Stream Options
” for users to determine which stream to be streaming. This
product supports dual-stream. Therefore, there are two streams to choose.
2. The second one is “
MPEG-4 Media Options
” for users to determine which media to be
streaming under MPEG-4 mode.
3. The third one is “
MPEG-4 Protocol Options
” which allows choices on connection protocol
between client and server. There are four protocols choices to optimize your usage – UDP
unicast, UDP multicast, TCP and HTTP.
z The
UDP unicast
protocol allows for more real-time audio and video streams. However,
some packets may be lost due to network burst traffic and images may be obscured.
z The
UDP multicast
protocol allows to save the bandwidth of server while serving
multiple clients at the same time.
z The
TCP
protocol allows for less packet loss and produces a more accurate video
display. The downside with this protocol is that the real-time effect is worse than that
with the UDP protocol.
z The
HTTP
protocol allows the same quality as TCP protocol and the user don’t need to
open specific port to streaming under some network environment.
If no special need is required, UDP unicast protocol is recommended.
Generally speaking,
the client’s choice will be in the order of UDP multicast → UDP unicast → TCP → HTTP. After
the Network Camera is connected successfully, “Protocol Option” will indicate the selected
