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.
