Know of this ?

I was talking to one of my clients that I do subby work for , about an upcoming camera job. He said "have you used adaptors before?" This guy is very untechnical & I gave him "the look" & said "more information" because "adaptors " meant nothing to me.
So what he is talking about is a device that allows more than one camera to run on a single coax. Now I'm well versed in the principles & practice of multiplexing as used in telephony but I have never seen or heard of this used for cameras. Can anyone shed some light on this ?

There is baluns that allow 4 cameras over 1 utp cable.

Then there is the VDS units which allow multiple Video/Audio/Power Over One Coax but are expensive, which outway the cost of installing individual cables. I have used this on an existing job where a existing cable existed and the costs of installing a extra cable or two was way too expensive ie ripping up a public road.

That VDS gear sounds like what he's using. Be interesting to see how it goes.

there good man. i did a job probably three years ago. had to add anohter camera to a light pole. there was no way of getting a cable there without trenching the car park. put one unit at one end anotehr unit at the other and job done, dont think i even had to set anything up, just plug and play

basically 2 in 1 out at one end. 2 in 1 out at the other.

you couldnt tell the difference with the picture either

Added bonus is you can power a 12v camera from the TX unit.

DAS/PACOM have them (as do others) and have adapters to allow megapixel IP Ethernet connectivity over 250m of coax...
Good for retro fit of older jobs
