I have analog low light cameras in my barn to monitor when my horses have their foals. The cameras are connected to agile modulators in the barn that put the signal on open VHF channels, the signal is then sent on coax 300 feet from the barn to the house where we have watched it on standard televisions in the past. A number of people would like to be able to access the cameras remotely to check the progress of the mares and let us know if they are going into labour if we are not watching the feed.
We had looked at switching the system over to completely computer based but are having difficulty finding a simple robust way of getting the wifi signal from our barn to the house so feel that staying with the wired system maybe be the best way to go.
I am looking for a solution to take the analog signal and change it to a signal that I can feed into the computer as a "webcam' then put on the internet. I have looked at the ATI wonder TV USB device but can't find information on it. I maybe looking in the completely wrong direction. I do have several old P.C.s that I may be able to use to accomplish the task.
The next step will be to put it on the internet. My thought is to go to a site such as Justin.tv. I have looked at that site and it seems to be a possibility. Any thoughts or suggestions would be appreciated.
