You cannot get a single run of 300 meters to work. - Undisclosed 3
Tell you what, you setup a 300M 100Base-TX connection over any approved Category Cable and I'll setup 20 100Base-TX switches with 100M of Crap 5 cable between them. Undisclosed 3

Notes: Total of 23 ethernet interfaces involved from camera to computer. Total switch cost: < $120 for 100 ports, 62 usable ports = < $2 per port cost. The switch comes in a ruggedized version for $3 more "Tough on the outside, Tenda on the inside".
Patch cables are 1 foot.
Assuming there are no questions to this test, cables will be changed first to 150 ft, then 300 ft for the 2km final test.
Doesn't quite have the same panache as "Kramer vs. Kramer" or "Spy vs. Spy" or even "Mr. & Mrs. Smith". Looking forward to the results though!
FWIW, I've done the daisy-chained switch thing before, in a large warehouse with several cameras along the way. Three cameras at the far end into one switch, that links down to a second switch with three more cameras, which links to a third switch with two more cameras, and then on to the IT room and into the main switch with the NVR and four other cameras at the other end of the building. Been pretty solid, too.
I don't think I've KNOWINGLY used anything over about 350'.
I used to work for a company that was rolling out upgrades to their remote sites, replacing token-ring with ethernet, usually by swapping the T-R wired jacks for ethernet version at the desk end, and changing the cross-connects on a BIX panel. In almost every case this was seamless, but we did have one site where a far office was getting a link but no connectivity. In tracing the wire, we found it had at least two splices in the ceiling, one right beside a large HVAC unit, and estimated it to be close to 350' the way it zig-zagged through the ceiling.
Oh, and did I mention many of these sites (including this one) were all Cat3?
Surprised ANY of them worked as well as they did... in this particular case, the company got the far office rewired with Cat5e, routed on a more direct vector so as to reduce the overall length.
Same question I was asked several times by my family, as they gazed wistfully into their former rec room...
I think the moral low point for me came when I subverted the 2 per household limit by having my eldest son go to the store later in the same day that I had, and pickup another 2 switches. Nothing beats being lectured to by your own in the same manner you lecture them:
Son: You know there's a good reason for the limit, right Dad?, They only have so many to go around. Legally, it's called hoarding.
Me: Oh, thx for the tip. Any idea counselor why they didn't tackle me when I picked the shelf clean of those 20 gender changers for 8.99 a pop? Besides, it's not hoarding, I'm returning them all tommorow, so...
