I remember seeing a device in a catalogue that cosisted of a unit that fitted on each end of an rg59 cable to allow 2 x cameras to send their images down the 1 cable.

I can't find the item now that I need it, anyone remember it.

I know it multiplexes the image and that the frame rate will be lower, but its only for an overflow car park. There is currently 1 camera on a pole with 240 volts, we want to add another camera without cutting through the concrete to run another coax.

Thanks for your input in advance

Baxall used to do a device that did this, controlled by telemetry signals essentially a fancy relay/switcher.

Norbain do a bit of kit that does this, not badly priced.

You mean one of these, this is the receiver end, somewhere in my shed i have a transmitter end and psu, you can buy them from Norbain as far as i am aware.

QFA yes you can. Not cheap though, but it depends on how much cabling you have to do.

I think it is a high speed switcher. It also does an alarm switch and voltage down the line. Used them several times with no problems.

Found the SNT Group site & it looks like their units will do the job.

Thanks for the advice.

Will let you know how I get on.

there was a company called norteck (not sure of spelling) that did a similar unit.

you would have a tx unit that you conected video sig into (adding daughter boards to increase inputsx8)

and via coax cable with aremote swithcer at the other end just flicking through the video sigs. it was ok for viewing but not good for recording.

if you are thinking of using less cable etc look at the balun systems using cat5 cable.

hope this helps

Read the original question, there's a single co-ax in that they're stuck with.

I've been in contact with SNT and intend using their unit (its not cheap), will let you know how I get on.

BTW they say their unit sends both signals in real time & will also send the 12 volt for the camera power.

This could be handy for adding a camera by cutting into an existing coax & just putting the camera there. Maybe useful for temporary coverts etc?

Theyre spot on, used them a few times in ASDA for carpark cameras or long runs where running a cable isnt really a viable option.
