Selection of the System Type
Depending on the system type, the network camera server works in different ways.
System Type
Description
Live View & Recording
Delivery of live camera pictures and recording can be performed. (Allocation of disk
space for recorded pictures is required on the server.)
Recorded pictures can be searched for and played when desired, and they can be
downloaded on a user's PC hard disk.
Live View Only
Only delivery of live camera pictures is available with this system type. Recording,
playback, searching and the alarm function are not available with this system type.
Note: The system type can be changed anytime if required. In case of switching from the "Live View Only" to the
"Live View & Recording", allocation of disk space for recorded pictures will be required.
Design a system fulfilling all of the conditions below to run the network camera server in each system type.

To connect 128 cameras, it is required to set the maximum bit rate at less than 230kbps and the maximum frame
rate at less than 1.5fps per a camera in the camera settings.
Refer to the following values for the maximum frame rate of cameras.
The following values may differ depending on objects to be captured and the network environment. Also,
depending on the traffic on the network, acquiring pictures at the maximum frame rate may fail.
Size of a JPEG (QVGA): Approx.15 - 22 KB
Maximum frame rate of WJ-NT104: 5fps (Settings of WJ-NT104: JPEG, Fixed Input Selection Mode, no limitation
for maximum bit rate, QVGA).
Maximum frame rate of WJ-NM100 (MPEG-4): 30fps (Settings of WV-NM100: bit rate of 256kbps or more,
QCIF).
