Network and Storage Considerations
The VND-970 IP Camera Dome can be connected to any ViconNet version 5.6 network. ViconNet NVRs, DVRs and Workstations can be used
for live viewing and recording of network-streamed video. A network can be as simple as a single camera connected to a ViconNet
Workstation or can be complex with the addition of several networks interconnected via WAN. Refer to the network diagrams on the next page
for sample configurations.
When adding a VND-970 IP Camera Dome to the ViconNet network, the following items must be considered:
• The number of cameras on a switch with respect to switch capabilities and system bandwidth mapping.
• Bandwidth limitations on ports connected to workstations (using 100 or 1000 Mbps).
• Workstation capabilities such as processing speed and disk write speed.
• Storage size and location types including local Workstation recording, attached SCSI RAID and integrated SAN devices.
Refer to the network diagrams on the next page for sample configurations.
The VND-970 offers a variety of configurations that impact on the video quality (resolution/fps) vs bandwidth usage. Maximum frame rate is
selectable, 1-30 fps. There is a choice of Constant Bit Rate or Fixed Quality. Constant bit rate maintains the bandwidth utilization regardless of
the video quality; Fixed quality maintains quality but the bandwidth utilization varies. A range of bit rates are available to choose from; select
from Medium, Standard, Good, Detailed or Excellent for quality. It is suggested that the Constant Bit Rate be selected, since it provides more
exact control over the network; the parameters shown below have been tested and proven to provide the best quality of video.
