Video Description

1. Video Format: sets the format for streaming

MPEG4 (main stream): Stream mode at MJPEG+MPEG4 or Dual MPEG4

MPEG4 (sub stream): Stream mode at Dual MPEG4

Motion JPEG: Stream mode at MJPEG+MPEG4

See Setting > Video / Image > Video for details.

2. View Size: selects the size of the image

Select the size of the image from 0.5 to 4 X.

Note: It’s not recommended to use 4x zoom in size to view the video since the

image will be abrasive due to the digital zoom effect.

3. Streaming: sets the video stream protocol (HTTP is recommended)

This product provides three different video streaming protocols: UDP, TCP, and

HTTP. HTTP is recommended because it allows the video stream to go through

the firewall. (Refer to Setting/Basic Setting/Network/Streaming for more

information).

UDP: provides the fastest but most unreliable transmission service. Video steams

are transmitted through UDP Port (50000~60000 by default) to ensure the

fastest image transmission. However, video fragment or mosaics may occur

due to poor transmission quality.

TCP: provides reliable data transmission. Video steams are transmitted through

RTSP Port (554 by default) to avoid video fragment or mosaics due to poor

transmission quality.

HTTP: Video streams are transmitted through HTTP Port (80 by default) to ensure

passing through firewalls.
