No, it doesn't (dude...). It has 525. And how many does it have the other way (vertical columns)? Hmm? That's right: not exactly defined in the analog domain. Which is why a broadcast camera is free to quote 700: it has a frequency response that gives 700 resolvable vertical lines in that direction, with 525 defined horizontal scan lines. Even lowly VHS has 525 scan lines. It has to: that's how NTSC works!
A broadcast camera claiming 700 lines is possibly analog, and certainly SD.
