OT Wireless transmission Camera to Monitor

[Chuck Pullen]

I have some suggestions, but they ain’t cheap! There are a couple of systems on E-bay that may be worth checking out. There is also something like the Trango system (check Markertek or B&H, they both sell a couple of systems) Basically without spending like $10,000 plus, you’ll not get great results…

Wish I had better news for you,

Chuck

Hi Chuck

No thank! Spending $10K is totally out of the question! 😉

Anyway I was trying to google some stuff and this page came up….

Dunno if that would work or not but I’m going to email them.

Actually we only need 100ft or so between a locomotive and the first car in the train. I just don’t want to hang a cable outside. I would think a 100′ composit cable wouldn’t carry a signal that far. We don’t need audio.

Thanks for your info. I will check Markertek and B&H.

That sounds like a fun project, is it steam or diesel? Here’s what I can tell you about the 2.4 GHz systems. They ONLY work well for what you are doing if you can meet all of the following circumstances; 1) You are not going to be using it to record or switch the camera. 2) You have a clear line of sight between the transmitter/receiver. 3) The transmitter and receiver will be fixed and not moving around.

There are some systems available for security cameras from say security cameras direct similar to what you are using, they also have some systems that have a higher power output from the transmitter which may help with a better picture.

Here’s my overall advice;

Go with the best 2.4 or 5.8 GHz system you can afford. Remember, the more power the better. Since the higher power units will rely on electricity, something you may not have on a moving train, you can rig up and adapter made up from large 9 or 12 volt batteries (or battery belts) that can run these for hours.

Hi Again Chuck

hehehehe Diesel, comuter train. I’ve been doing technical video work for railways since 2002. Anyway to answer your points.

[Chuck Pullen] “1) You are not going to be using it to record or switch the camera. 2) You have a clear line of sight between the transmitter/receiver. 3) The transmitter and receiver will be fixed and not moving around.”

1. Not going to use it to control the camera. Like I said I’d be at the camera.

2. Through the engine and into the coach? I don’t think that’s a clear line-of-sight 😉

3. Yea, I can say that. the camera is locked down except for panning and whomever is holding the monitor won’t be walking around.

Anyway I did find this……

…..but I’d bet dollars to donuts that it’s way outta my price range.

It should be battery powered however since I’m a railroad guy, I already got a power inverter from the last railroad I worked for, that clips to the 72v battery terminals in the engine and inverts to 120VAC but don’t need to use it much as my Anton Bauer Hytron 140’s will power my DSR-250 for about 12 hours. 7 with my nNovia digital recorder connected. I used to use it when I used my laptop and DV-Rack to record.

Allen, I used to work for a production company who did a weekly show at the local harness racing track.
We ran video lines to/from 4 cameras with the longest run being over 300 ft. with no problems at all.
The key is to use a much higher grade of coax than your local big box store sells.
We were using the same cable that the local TV station used in all their applications.

Hi Mike
Happy Thanksgiving

Thanks. I wasn’t sure about how long a run you could have. I know there’s limits to say FW and maybe USB cables but wasn’t sure about composite. I think you canbuy boosters for the FW and USB but the monitor is composite connection.

I also just don’t want to have to tape a cable outside of the train between the locomotive and first car either but we’ll do what we have to. We cold snake it hrough but then you wouldn’ be able to close the door to the engine room where all the noise is.

I have been running up to 300 ft. from a multicam switcher for many years in a variety of conditions. Sometimes just straight from the camera. We always use top grade cable with BNC connectors. We also have some 100′ Svideo (YC) cables that work fine. You can also use Firewire if you get the right boosted cable or a standalone booster. We have run 70′ ft. Firewire with no booster numerous times to a Firewire to composite breakout (a simple DV camcorder will work).If you want to go wireless, just rent. The bigger rental houses will give you all of the detail and prices. Good Luck!

Hi John
Thanks. We wouldn’t be running FW. Either RCA or BNC from the DSR-250 to an Ikan V7000 monitor. If I remember corectly the breakout cable for the monitor has a BNC.

Didn’t think about renting but yes there’s probably hundreds of big supply houses in LA.

Hi, Seems like your best solution is to run over CAT 5. Yes, there are such things, using a dedicated Video or A/V balun transducer, which converts to a digital signal and runs over a dedicated CAT5 cable. google “video over CAT5” you’ll find lots of suppliers. You need a dedicated balun at each end, and it can run off a simple 12v gell battery.
