Tap into video feed

[jtetterton 0]

I'm installing an analog system for a customer and he currently has a 2 channel CCTV system in place that has a very specific purpose and will not be removed. It does not record currently.

 

What I would like to do is simply splice into the video feed at each camera and use a T BNC connector or Y adapater with a balun and send the spliced signal off to the DVR. This should allow the current system to remain intact and operating and simply add a recording component off the new feed.

 

Will this work?

 

Thanks,

Yes.

I love it when a plan comes together! Thanks for the answer Soundy.

What would work BETTER, if the system layout allows, is to feed the cameras into the DVR, then chain them on to the original destination from there (assuming the DVR has pass-thru inputs). Inserting a T-connector will cause a drop in signal level and a corresponding (hopefully) slight drop in image quality... chaining through the DVR would allow it to maintain proper loading on the cameras.

I thought about that but the DVR is a good distance away from the cameras and the DVR I've already quoted does not have loop through.

Understood. Unless this is a particularly crappy system, splitting the feeds should cause only a very slight drop in the image.

jtetterton, see if it's possible to turn the termination on the customer's monitors off (or to Hi-Z). That way you'll have minimal signal loss.

Otherwise as Soundy says, you'll lose some of the signal, but could compensate by adjusting brightness and contrast a bit.

1 feed in with two outputs. booster. if your dvr is a distance away.

That's interesting. I could probably just tap power from the camera as well. Is that 12 volts?
