Video Input Settings
Video Standard
This is the video standard of the input video, which can be either NTSC or PAL. Generally, the NTSC
standard is used in North America, and the PAL standard is used in Europe and Asia. This setting will
affect both the video resolution and the frame rate. Modifying the video standard requires a reboot of
the encoder to take effect.
Horizontal Position
Use this setting to apply a horizontal translation to the video. This is useful in removing artifacts from
the camera borders.
Vertical Position
Use this setting to apply a vertical translation to the video. This is useful in removing artifacts from
the camera borders.
Frame Format
This parameter determines how video frames are represented in memory. This can be set to field over
field (default), interlaced, or de-interlaced. Set it to interlaced or de-interlaced if you are streaming
video to a non-Verint MPEG-4 decoder (codec). If you want to get rid of interlacing artifact at the
source, you can set the video to be de-interlaced. If the same image appears twice, one overlapping
the other, the settings on the encoder and decoder do not match, and one setting needs to be
changed.
Video Rotation
This setting is available only with some S2600e camera models. It indicates whether the video must
be rotated 180 degrees because the camera has been installed upside down.
Number of Encoders per Video Input
This sets the number of available video encoders — one or two. Setting this value to 2 allows you to
use two different logical encoders — for example, one for video that will be viewed live (high quality)
and another for video that will be stored (low quality). Be aware, though, that some product options,
such as the Noise Reduction Filter, are available only if the number of encoders is set to 1. If this
number is changed, the unit must be rebooted for the new setting to take effect.
Max Video Payload Size
This parameter controls the maximum packet size that can be sent over the network. It has no impact
on the size of each frame or on the bit rate of the video.
