Are these systems 'bluetooth' and fight for throughput?

Huh? No Bluegoof in sight. What you're thinking of is 802.11b/g also
known as Wi-Fi. The problem is that 4 active Wi-Fi cameras will
occupy 100% of the available bandwidth in the 2.4GHz band. They will
also trash your 2.4GHz cordless phone, your wireless internet to your
laptop and iPhone. The picture will go nuts when you run the
microwave oven. Wireless cameras are a dumb idea. Use coax cable, or
get a pair of baluns and use CAT5 for the cameras. I switched to CAT5
and am living happily ever after.

That wasn't very clear. Wireless security camera systems do not use
Wi-Fi (802.11). They use conventional NTSC analog transmissions on
approximately 1/4th of the 2.4GHz band. It's not VSB as the signal is
about 12MHz wide. There's no acknowledgements from the receiver, and
there's no listening on the channel to see if it's occupied. Just one
way broadcasting and interference to existing Wi-Fi systems. Sorry
for the muddle.
