Network connection
speed
This unit supports the connection with 1000Base-T
(1 Gbps) or 100Base-TX (100 Mbps).
When you connect the unit to the network, negotiate the
communication speed with the connected equipment
and start communication at a higher speed of that both
equipment are compatible with.
When using the unit with 100Base-TX connection, the
frame rate to be output is limited, because the output
data band width from the camera becomes narrow
compared to the 1000Base-T connection.
The camera has a buffer to store multiple images and all
of the shot images are stored once in the buffer.
The stored images are output from the camera in order
starting from the oldest image in the buffer.
Therefore, if the frame rate during shooting is faster than
the frame rate that can be output from the camera, the
image data will always be stored in the buffer, and the
time interval from shooting to image output becomes
large.
To avoid this situation, it is required to set the shooting
frame rate to the proper value when using 100Base-TX
connection.
The data rate of images is obtained by the following
formula:
Data rate = Width
×
Height
×
BPP
×
FPS
Width: Width of image
Height: Height of image
BPP: The number of bits per pixel depends on the
PixelFormat setting
FPS: Frame rate [frame/sec]
It is possible to minimize delay by using the camera at a
frame rate where the data rate becomes low with a
margin against 100 Mbps.
Notes
• Any persistent IP address can be entered, but the
camera may become unable to be detected, depending
on the IP address setting. If this occurs, use a tool for
issuing ForceIP and set a persistent IP address again.
• When setting the parameters (Width, Height, and
PixelFormat) for calculating the payload size, stop
camera image output beforehand.
