It will. Even if the frequencies aren't exactly the same, it'll be so
close that it'll greatly reduce your range.
You could just use 72 MHz gear ...

It might, but it's a smaller issue than with a plane. If your
wireless networking and your camera interfere, nothing goes out of
control and crashes. You probably can adjust your channels so they
don't overlap, something you can't manually do with R/C gear.
| I've also found video transmitters in 434Mhz, 900Mhz, 1.2Ghz, and 5.8Ghz.
| Just wondering what will perform the best.
In general, the lower the frequency the better the range will be, but
there's so many variables that this rule of thumb is next to useless.
Note that some video systems require a ham radio license, and to use
them you also need to abide by ham radio rules -- most notably, you
have to identify yourself every 10 minutes. For video use, that
generally means holding up a card with your call sign every 10
minutes. 434 MHz and 1.2 GHz are in ham bands, so they will fall into
this category. (If the power is low enough, you can use them without
a license, but the power isn't going to be low enough for a video

As long as you want to monitor them from within your house you're
probably fine. If you want to get it from across town, probably not.
