Cctv connector. What is this called?

[Nobody Important]

Colour me blonde.

I'm replacing my cctv cameras, and these new ones have (in addition to the standard analog connector and DC connector) a third connector that I don't immediately recognize.

What is it?

It's a reset button for an IP Camera

Press to resart, or hold in (and power up) to factory reset.

Analogue cameras? To change the modes. My Hilook analogues have them.

And here I was thinking it's a connector.

Since it's a 4 in 1 camera, you may find that you have a recorder that only supports a single format like AHD, or doesn't support HD at all and only supports CVBS. You use that switch to reset to a compatible format.
