VIVOTEK IP8371 or IP8371E is a professional outdoor bullet network camera offering 30 fps @
3-Megapixel or 60 fps @ 1080p resolution with superb image quality.
Featuring 3D Noise Reduction Technology, it enables the IP8371 or IP8371E to capture clear,
polished video under low-light conditions, which also helps to reduce bandwidth from sensor
noise.
The IP8371 or IP8371E also features Smart Stream Technology, which can be used to optimize
resolution on a desired object or area to maximize bandwidth usage.
The IP8371 or IP8371E comes with a P-iris lens, which controls the iris with extreme precision
with its built-in stepper motor. By using software controls, the lens maintains the iris opening
at an optimal level at all times, resulting in superior sharpness and depth of field as well as
image quality. For installers, properly adjusting the focus of a megapixel network camera can
be difcult due to the image detail. Thus, VIVOTEK has introduced the Smart Focus System to
make installation and adjustment easier by allowing for remote focus and zoom adjustment.
The IP67-rated housing is designed to help the camera body withstand rain and dust and
ensures operation under a multitude of harsh weather conditions. Additionally, the wide
temperature range further enhances the IP8371E’s performance and reliability in extremely cold
and warm weather.
Revision History

H.264 / MPEG-4 Media Options
H.264/MPEG-4 Media Options
Select to stream video or audio data or both. This is enabled only when the video mode is set to H.264 or
MPEG-4.
H.264 / MPEG-4 Protocol Options
H.264/MPEG-4 Protocol Options
Depending on your network environment, there are four transmission modes of H.264 or MPEG-4
streaming:
UDP unicast: This protocol allows for more real-time audio and video streams. However, network
packets may be lost due to network burst trafc and images may be broken. Activate UDP connection
when occasions require time-sensitive responses and the video quality is less important. Note that each
unicast client connecting to the server takes up additional bandwidth and the Network Camera allows up
to ten simultaneous accesses.
UDP multicast: This protocol allows multicast-enabled routers to forward network packets to all clients
requesting streaming media. This helps to reduce the network transmission load of the Network Camera
while serving multiple clients at the same time. Note that to utilize this feature, the Network Camera must
be configured to enable multicast streaming at the same time. For more information, please refer to
RTSP Streaming on page 73.
TCP: This protocol guarantees the complete delivery of streaming data and thus provides better video
quality. The downside of this protocol is that its real-time effect is not as good as that of the UDP protocol.
HTTP: This protocol allows the same quality as TCP protocol without needing to open specic ports for
streaming under some network environments. Users inside a firewall can utilize this protocol to allow
streaming data through.

Local Streaming Buffer Time
In a busy network, fluctuations in available bandwidth can occur. Video streaming may lag and may
not proceed very smoothly. If you enable this option, video streams from the camera will be temporarily
stored on the computer’s cache memory for a configurable period of time (seconds or milliseconds)
before being played on a web session. This will help you see the streaming more smoothly. If you enter
3000 Millisecond, the streaming will delay for 3 seconds.
