4 channel IP NVR but with 4 concurrent BNC video outs??

Recommended Posts

Hi all,

 

This is my first post ---- I've done some searching and I've called up some vendors (one in TX and one in FL) that commonly advertise DVR / cameras and I've run into roadblock --- so I am here to ask for help, if anyone is willing to share! I understand as a newbie to this forum that I can stand to learn a lot and I'm probably asking some stupid questions --- so bear with me....

 

I'll get to the point. I have a 4 channel analog system that records at D1. I have cat-6 pulls to each camera. I cannot pull more cable. Currently the cameras as all analog cameras using baluns to pull power and video over Cat 6.

 

I'd like to upgrade to a new system with much better resolution -- Full IP or HD-TVI or whatever. The constraints are though that -

 

**** The System has to accommodate 4 separate composite outs (for 4 cameras channels) for my old LCD monitors that are built into the wall. I cannot rip these out.

 

**** I do need 4 channels of composite out for the 4 cameras ---- I cannot have a multiplexed signal because the old LCD monitor system does the multiplexing.

 

**** I don't care too much if I am running IP over CAT6 over baluns over CAT6, but I cannot pull anymore cable.

 

My main problem is that I don't know how to design the DVR/NVR. I'm computer saavy but have 0 experience with building NVRs. I don't the the right combo of equipment to do what I want to do. Since the current analog DVR uses all BNC/coaxials for video, I use external splitter boxes to split to my hearts content from each camera to feed (1) the DVR and (2) the old LCD monitor system on the wall.

 

I've attached a diagram if that helps. Thanks so much.

You won't find NVRs with a BNC output; I have not seen any. You might find one with a BNC output...? Maybe, but surely not with 4 BNC outputs. Oh wait, you don't want an NVR, you want hybrid (3 IP camera, 1ch analog).

 

With Hikvision you could use an hybrid like DS-7604HI-ST, and then a decoder to output 4 streams on 4 BNC outputs, like DS-6704HWI.

Hi MindTwist, thanks for your reply.

 

The Hikvision DS-6704HWI --- I thought these are video servers --- meaning they take BNC IN and and IP (RJ45) OUT.

I was looking for some way to take multiple IP cameras and have BNC OUT for those IP cameras.... (for compatibility with my old LCD monitor systems in my walls) ---

 

Am I mistaken?

 

Here is the DS-6704HWI data sheet - http://www.lobeco.nl/files/DS-DS-6700-Series-Encoder.pdf

My bad. I pointed you to encoders, instead of decoders...!

 

Decoders should be DS-63xx and DS-64xx series. I think DS-6304DI would be the cheaper option.
