It is for monitoring 5 cameras. The camera setup is in place and working over the internet using dial up, but it is too slow. The picture updates only about every 5 to 40 seconds. I assume that internet traffic is the variable. Once every two seconds or faster would be good. What do you recommend for wireless through a fairly wooded area? And again can the phone company provide a connection in the existing buried wiring? They always have extra pairs available, right? Both locations are on the same dead end road.

A "leased line" is not just renting an extra pair of wires, it actually is a datacom service that is configured, optimized, monitored, and $$$. And yes - they usually are a hub & spoke arrangement with say 2 points near each other actually going all the way back to the telco exchange for the "electronics" portion. Any other options ?? Is this on your property - is there a fence or other "path" where you might be able to string some cable ? | ||||||||||||||||||||||||||||||||||||||||

and others. One catch is that the throughput is rather limited.

It is sometimes done for alarm companies. It might be that it is harder than it used to be, as phone companies want to be in the datacom business. I know public schools that do it for their T1 lines instead of leasing T1 lines. (For schools close enough to the district office or to other schools.) Libraries might also be able to do it. -- glen | ||||||||||||||||||||||||||||||||||||||||
