Ethernet to hdmi video converter

Our current video setup is:

- ethernet from the camera in the chapel
- to an ethernet-to-coax converter in the satellite close
- to a coax-to-RCA adapter
- to the omniprice rca-to-hdmi converter
- to the vidiu device.

What is the degradation of the video in this setup?

Would an ethernet-to-hdmi converter be worth it in this situation? If so, does anyone have recommendations on an ethernet-to-hdmi converter and vendor?

Is your camera IP only?

If yes then you will need to use a laptop to run a program called directshow, then another program that will pick that up as a video source.

If no then all you need is the church recommended composite to HDMI for the vidiu

To many unknowns to give solid answer.

What kind of jack is on the back of the camera? I have a feeling that by "Ethernet" you really mean "Cat5" or "Cat6" - a network style cable. And the camera is really a composite output. You also haven't explained what specific video issue you're having. I'm pretty sure you're starting out with standard definition video, and so the output will not be HDTV.

You might try taking the camera and going directly into your converter by placing them all in the same location. That will tell you what your equipment is capable of.

The camera is an EVI-D70, mounted (semi-)permanently in the chapel. Cat5 & cat6 are types of ethernet cables - I don't know which category it really is. But, it's a network cable, presumably a higher-end cat5e or cat6. There's also a (copper?) wire that connects the camera to an infrared sensor in the satellite closet for use with a camera remote control. We don't use a pc to control the camera.

The degradation isn't that bad. I thought the monoprice converter degraded the signal somewhat. A couple others weren't sure but thought it might be best to not convert the signal so many times.

It's kind of a mute point now that I have revisited this. The coax splits in two. One goes to the the vidiu (eventually). The other goes to a modulator that feeds the signal to all the other rooms in the building. We have modulators for channel 3 (satellite english), channel 6 (satellite spanish) and channel 10 (internal feed). The channel 10 modulator is fed from the camera, via ethernet cable, to a coax converter to the modulator.

Oh? If that's not a active device (meaning that it uses power), that's a problem right there. You can't "split" baseband video. It would have to be some kind of distribution amplifier. (An amp with more than one output.)

Since the EVI-D70 does not have an Ethernet jack, how are you able to connect the CAT5/6 cable to the camera?

Perhaps there is some kind of adapter connected from the CAT5 wire to the camera's video jack?

If BALUNS are not being used on each end of your CAT5/6 wire, serious degradation of the video signal could be the result.

- ethernet from the camera in the chapel
- to an ethernet-to-coax converter in the satellite close
- to a coax-to-RCA adapter
- to the omniprice rca-to-hdmi converter
- to the vidiu device.

Here is a proper way to run the signal:

RCA jack from the EVI-D70 video out to a balun (converts to RCA to CAT5)
CAT5 to the satellite closet
CAT5 from the camera to another balun (converts CAT5 to RCA) in the satellite closet
RCA to Omniprice RCA-to-HDMI converter
HDMI to Vidiu device

Another culprit of a degraded signal is:
The coax splits in two

The proper way to get additional composite video feeds is with a Video Distribution Amplifier.
