13.3 Ethernet Local Area Network (LAN)
Ethernet provides almost instant connection and faster update rates than ISDN. A VDC Ethernet module is
already installed in the VDC and the PC must have an Ethernet card installed.
Image update rates of around four images per second are typical, depending on the image quality selected
in the Vi-connect remote access software. Local area networks (LANs) generally employ Ethernet hubs or
switches, and the VDC plugs into this in the same way as a PC. Standard CAT5 cables are used throughout.
Any number of PCs can access any number of VDCs on a one-to-one basis, subject to the size of the
network. The network can be an independent network for the CCTV, or an existing computer network. In the
latter case, the network administrator may need to designate suitable IP addresses for the VDC(s) that avoid
conflicts with the PCs and printers on the network.
