Recommend external mic for LTS Camera

[n0fx]

I bought the LTS CMIP7243W-SZ and thought it had a built-in mic but I was wrong. I need to hook up a mic to it via Audio I/O. I area that I want to cover is probably less than 20 ft from the camera, I was wondering what type of mic do you guys recommend to use with it?

Does it have a RCA port if so you just need any mic, preferred to have a powered mic. If it's a bnc port just get a bnc to RCA adapter...

There is no RCA, it's one of these:

Is there any way to convert from that plug to standard RCA for it?
