Reddit reviews RiteAV - BNC Male to RCA Female Adapter

Oh, that looks like a scam product. Both connectors, BNC and RCA (cinch connector) are just 2 conductor. One signal one ground. So you can literally cut off one plug and solder on another. Spending 100 dollars on it is a huge waste of money. Like the other person said. A ferrite bead may help, but those are also cheap. These are fine (https://www.amazon.com/RiteAV-BNC-Male-Female-Adapter/dp/B000V1R97U)

You just need a tuner with ypbpr outputs (composite HD) and 5 rca cables with bnc adapters.

That's a BNC connector.
You need a BNC to RCA adapter. This is the first result on google, but you could probably find it cheaper.

Once you get that, you'd connect it to the top middle terminal, next to the "O" in "VIDEO".
Then you'd need to connect the Yellow end of the RCA cables to that.
Next you'd connect the White RCA cable to the same spot it's already connected on the VCR.
You can remove the Red cable on the VCR, as it's currently connected to the Audio In on the VCR. That VCR is a mono only deck.

The wires are connected properly on the TV.

After reading over your projector's manual this should work:

You'll need these:

I believe it's a way to add the component input into your projector. Those cables I put weren't the cheapest. There are five outputs for the computer in, two will not be used. You will also need the BNC-RCA connector but with a female input not male like the one showed in the picture. Then change the INPUT SELECT on the back to ANALOG. I Hope this helps.

Looks like it takes composite video through BNC on the back.

If you have an old PC, it may output this directly. Otherwise find an HDMI to composite adapter, VGA to composite adapter, or other device that will convert modern PC signals to composite video.

Then just get a BNC to RCA adapter: https://www.amazon.com/RiteAV-BNC-Male-Female-Adapter/dp/B000V1R97U (these can be found on ebay for like 20 cents)

Do be warned this will probably look pretty bad. Composite video is going to be 480i max, and as a combined signal it won't be very sharp.

Does that work? BNC->RCA? Like https://www.amazon.com/RiteAV-BNC-Male-Female-Adapter/dp/B000V1R97U

So the signal is the same as for normal RCA?

Is it BNC?

Based on this feature sheet I found googling the name, it looks like it can take NTSC or PAL video, so a composite input should do the job. One of these will change the plug to something you can use.

Coax typically carries signals that are mixed so many channels can be sent on one wire, which requires a tuner inside the display. Surveillance systems often don't support this, and run one line per camera. Those that do support the mixing are called CCTV (closed circuit television) systems. Even then, though, usually each camera has its own line that goes to a dedicated mixer.

An unmodified Super Famicom Jr is only able to display composite as stated in comments before. I don't believe that your current cable setup will work, if you have an ordinary SNES AV composite cable like this one http://www.akjgaming.com/wp-content/uploads/2016/04/snes-av.jpg you should be able to connect that straight to the monitor with only a RCA to BNC adapter like this one https://www.amazon.com/RiteAV-BNC-Male-Female-Adapter/dp/B000V1R97U in between.

I believe that the comment about the BVM settings that Kjeldvk posted are correct.
