There is too much to record - over 150 cameras 24x7x365. They just don't record them.  Would TDOT be up for having a non profit/private party provide hard drives to record this information and provide it to the public on a rolling 48 hour basis? I know you work for channel 5 and not TDOT, but do you suspect they would be open to such a proposal? Said another way, is it possible to get the raw feed from TDOT the way channel 5 does, or is the public forever limited to a low res 8 second delayed image? Andrew McElroy   TDOT gives the local TV stations a connection to their Cisco data switch and we have a private Metro Ethernet circuit between their facility & ours. The cameras are an IP multicast stream and each runs at about 3mbps each. For 150 cameras, that's 450mbps of data to do something with every second. We decode two streams into NTSC video and use those on-air. You would have to talk to TDOT and undoubtedly sign a camera use agreement, similar to what the TV stations have signed. I have no idea whether they would agree to have a third party store the camera video or not. I do know that would be a rather sizable collection of disk drives to save all that video for 48 hours, like you mention. That is somewhere in the neighborhood of 38,880,000mbps per day.
