OT: long distance video feed (video over CAT5, fiber, IP…)
OK, I know this is off topic, but I feel more confident with you at this forum.
One of my clients is a hospital and we have been feeding composite video from the surgery to monitors 160 meters (525 feet) away, with an acceptable loss of video signal. Until now we have been laying out the cables (75 ohm coax) through the windows and over the roofs, but we are now going to make a permanent installation from the surgery, at second floor, straight down to the cellar and then up to first floor.
We will be covering two surgeries with two cameras, mono sound and talkback each, which make eight lines of coax. The building is 130 years old and, as it is now, we could add two or three single cables to the existing installation down to the cellar without opening any new holes, but NOT eight cables nor a single multichannel snake (too thick).
I’ve been thinking about the following options, and I would like to know your opinions and/or suggestions:
1) Single multichannel snake containing eight RG 59 (RG 6?).
– pros: future proof, can be upgraded to SDI or HD-SDI.
– cons: will not be easy to install; loss of signal; unbalanced audio.2) A/V over CAT5 with a balun.
– pros: no need of drilling; un-expensive (at least the passive baluns); multiple versions (composite, component, SDI, HDMI…)
– cons: ?
Passive balun: https://www.etslan.com/Video.htm3) fiber optic cable.
– pros: distance no issue; future proof.
– cons: expensive (I believe…); the need of special tools (and knowledge) for installation and testing.4) Video over IP.
– pros: could use existing LAN.
– cons: expensive; the need of one set of encoder/decoder for each camera.
Encoders:

https://www.qvidium.com/IPCodec.html5) Multiple multiplexed audio/video streams over single coax (does this exist?).
Any thoughts? So far I’m leaning towards the balun option, but this technology is totally new to me, so I’ll appreciate any comments from somebody more experienced. I should also mention that the budget is quite limited…
Thank you,

Look into Telecast Systems, they are the industry leaders in remote camera controls and 1 strand of their tactical fiber will easily handle all of your needs for this.

I have seen fiber runs from these guys at distances over 5K for World Cup and the Super Bowl
thier CopperHead systems allow for addition to most 1/2 and 2/3 in cameras and some 1/3 cameras like the JVC 200/ 250 so nearly all models are covered.gary adcock

Thank you, Gary.
Looks interesting, but expensive… I’m going to check the prices with the Spanish distributor, Clearcom.Meanwhile, do any of you have any experience with video over CAT5?

Petter,
Fibre. Fibre. Fibre!
Don’t dismiss it as too expensive. Compared to the multiple runs you’re looking at, I’m willing to bet that it will be a break even cost.

Sorry, no Petter,
my work has been exclusively HD for a few years, and CAT 5 is not robust enough for HD data streams in addition to the camera control protocols and return for the operators.

Thanks, Gary.
I’ve asked for an estimate on the Telecast POV & HD/POV modules from the Spanish distributor, but I’ll need a “Plan B” just in case my client can’t afford it…
