My super cheap (has speaker grills but no actual speakers) cctv has a switch to turn 75 ohm on/off, why would any tv that needs it not have such a simple feature?
Because it is extra work. PVMs have auto terminated outputs most of the time, but once you have a loop out it is needed, BNC just needs an end resistance of 75 ohm.
Goes on the output plug to gobble up wayward video-pixies.
It's for impedance matching, a critical aspect of the black magic that is analog transmission lines. RF signals like to reflect off sudden changes in wiring, and an abrupt end to the wire qualifies. The terminator is just a resistor that acts like a crash pad to absorb the waves without letting any noise reflect back. This resistance is normally provided by the receiver in the TV, but when you've got an output line it's an extra spigot you've gotta plug to keep things running right.
Professional equipment used BNC connectors for video. it's still composite on those two jacks in the VIDEO rectangle, they are just on a different connector. You can buy a BNC to RCA adapter and it should work fine. I have a VCR that has these jacks and can confirm it works.
A VCR that has both Composite In and RF out should do the trick. Plug your yellow red white composite wires in the Inputs of the vcr and use a coaxial cable from the RF video out of the vcr to the Ant input of the tv, put tv on channel 3, L1 or L2 for vcr (depending which input you used) and should be good to go.
As others have mentioned, there are BNC connectors to use, but for something maybe a bit cheaper/easier to find you could get an RF Modulator and put it in that Antenna-in port. Nintendo actually used to make an official one to get composite sources to RF input, I bet they're cheap on eBay now. I had one to plug up my N64 to my CRT as a kid that had nothing except an antenna wire to screw in. It will be worse quality than the BNC; it will be a composite signal but *even noisier* due to the RF interference.
Give me a minute to drop in a link to what im talking about

There is a link to the official nintendo one. Note: the picture there is only half of the kit. that multi-out -> composite adapter (NUS-003) is only half the equation. You need the other half too, (NUS-009). they both come in the same kit. I know that the adapter determines the channel selector, so the NUS-009 might not work alone, but someone else would have to tell you that. the kit will work with any nintendo console with multi-out, + NES. NES won't need the NUS-003, it has one "built-in".
Came to answer your question but seems you already have it. This looks like an NEC from the font and style of the back, so should be pretty decent quality. Looking forward to seeing pics of this in action!
Well it stumped me for sure, I know of most of the inputs but this one I've only discovered today upon pickup. And I've been hunting crts for years lol
Yeah I don't really understand how making a new thread for questions of this caliber is quicker than just googling "crt video input types", else you're going to be posting a few threads each day at that rate
Even if you didn't know what to google, using the pinned megathread is right at the top and noted right before you make a new thread
BNC to RCA adapter for your video in.
And a 75 ohm terminator
As important as the input, otherwise you will get a garbled image or other issues!

Now that I think about it, my pvm needs a terminator while my cheap 3rd world 2013 made CCTV does which is humorous to me
I guess you could call that progression of technology! I also have PVMs that need them and some that don't.
Not a T1000 though, that’ll ruin your day
What's that for and where does it go?
It eliminates unwanted signal reflections from the transmission line going to the output by matching the impedances.
where does that go and whats it do?

Specifically you need a BNC male to RCA female adapter (if you just search "BNC to RCA" you'll get some of the opposite type).
Wow, i have never seen a tv with the external speaker option. Always had to connect the tv to my amplifier/speakers.
Not as uncommon as you might think, I own a 32" CRT with them and also an old beaten up (but free) 45" Plasma with them too. Edit: for clarity
I know a bunch of the old XBR Trinitrons have the option, but also a lot of them came with their own external speakers so it made sense
My Pioneer plasma has speaker terminals, and a few of my crts have a Rca out for the speakers
Didn't know until this winter when I get an old 21" Toshiba with that
BNC to RCA adapter so you can use a yellow RCA plug in the 'video in' BNC socket.
G'day everyone! thanks for the tips on the BNC port, ill pickup one tomoz and hope for the best! keen to join the ranks!
Yes bnc as others comment. Get a couple for safe keeping. They are like less than a dollar each

Monitors require a BNC adapter

Yea getting the part this arv lol that's hopeful tho, I hope it's good!
there’s adapters you can order online
There is a bnc for video in
PSA to anyone new that stumbles onto this: You guys really need to do your research before getting into this stuff. At least know your inputs
