IP cameras on ring topology, not star

Pat Coghlan · 2006-04-27T13:13:15+00:00

I'm looking for information on equipment that can/should be used to install IP video cameras on poles around a perimeter (1-2 km, or more).Token-ring routers typically require all drops to be plugged into a panel (operates in token ring fashion, but physically is a star), which is not practical with 100 cameras running around a ring, feeding traffic back to recorders.The equipment needs to be economical (hub on each pole).Any suggestions or real-world examples out there?Thanks.

This may be a good opportunity to educate your customer on secure wireless technology. Secure, encrypted wireless is in many ways more secure than hardwired systems. You can't cut wires where they don't exist.

If your customer is worried about interference, check into licensed wireless and stay away from the 802.11 stuff.

We've done numerous projects using wireless technology including DHS and DoD sites. Well known examples are the Port of Oakland and MassPort.

An additional benfit with wireless: you're looking at using hired mooks to set it up and want the simplest cabling solution possible because they aren't that technically competent... wireless would eliminate that problem: the cameras could all be pre-configured in your shop or office or whatever, so all the workers would need to do is mount the cameras and plug them in to power.

As this is only a temporary installation, what's supposed to happen with all this equipment afterward? A lack of cables would certainly make take-down and cleanup a lot more efficient.
