I don't use an CCTV cameras at the moment, but when I looked into them most just had a positive and negative wire for power or a circle plug. So typically any 12V power supply transformer with enough amps should do it. You might need to lookup which CCTV cameras specifically.

I'm not endorsing any company, but see this SDI cable has a DC Power cable along with it:

Another one:

Otherwise you can run something like Figure 8 Speaker cable, which may not be the cheapest cable in the world, but I've used it before for running DC power and seems to work well. It's just what my AV guy had in his truck. Comes in many gauges, generally thicker has a lower resistance.

I would only be concerned if whatever power cable you used lost too much power along the way causing your SDI Camera to dropout. A multimeter would help you out seeing how much the voltage drops as you add more cable. A 12V Transformer often puts out a little more than 12V and the device would have some tolerance built in like +-1V. What that would be, well you would have to ask the people who sell it.

Or there is a calculator here: http://www.calculator.ne...es=0.5&x=65&y=10

You can buy the cable on a roll from and DC barrel type end connectors you can solder (better) or crimp on from an electronics store. They would most likely give you better advice about what would work well.

This website seems to have the whole package and videos on how to make the cables:

I'm still a little confused as to how to power it, As I stated I'm aware of cables that have the DC power cable latched to the SDI cable. I'm saying whats the best way to power it on the other end (especially if I have multiple cables)

Wouldn't I need a DC power plug?

Also,

Are the cable plugins for the DeckLink Quad DIN plugins? If so, do I need to get a SDI to DIN connector?


I was looking at IP cameras but I'm afraid of latency issues (especially if I have 2 cameras that are HDMI connections through a capture card)

Would it be better just to stick with HDMI and get a Quad HDMI capture card?

I'd rather have something I wouldnt have to recharge... if thats what you were suggesting... I'm just trying to think of the best way to power it (whether its in my sound booth or have the electrician install closer to the camera itself.

If I were to get the cables with both the SDI and DC power latched together, I was thinking I could get a industrial power strip and stick it where I have a rack mount and plug them in using DC power plugs.






Thanks for the clarification.



I currently already use 2 HDMI cameras with 2 separate capture card (single inputs) and I haven't had a problem with them.

xbamaris, You didn't mention or I missed that - what are you going to broadcast? Are you going to setup all your cameras, vmix pc, mixers, cables everytime or it will be fixed, one time installation and you are only going to turn everything every event. Also, will your cameras move up-down-left-right during broadcast or there will not be any movement (except zoom-in and out, maybe).

If:
- you are going to setup your cameras and connect cables to it every event,
- move (turn, rotate...) your cameras during filming,
- you need long distance cable
...use SDI.

If not HDMI may be enough.

There are 2xSDI capture cards, like Decklink Duo or XI200DE-SDI Magewell you may consider using with your current 2 x HDMI cards.
