A/V transmitter/reciever Questions

Hi! I'm trying to put together a body-wearable audio/video tx/rx unit. I've been surfing the internet for hours and have emailed retailers asking questions. Right now I'm very confused.

My confussion is from the specs they advertise. I read a spec for one a/v transmitter and then I find another spec from a different retailer of the same item but different transmitting range. :cry: I already have a headache and I've given up on finding out whats right and not.

What I've gathered so far is that a 900 mhz tx is good for mobile signals while a 2.4 ghz isn't but has 10-20% penetration power and suited for stationary units. The higher the mW output has better range. So far, I have chosen this and would like to know if the specs are accurate.

So, as a last effort, I turn to this forum to ask experienced hobbyist. What I want to get is an AV transmitter and receiver that has at least a 1 mile range LOS. The farther the range, the better. I ask advice on which one and where I can purchase it. Price range for tx and rx unit combined preferably below $1000(cheaper the better :lol: )Also, please correct me if I have been misinformed. Thanks in advance.

PS.

I need a colored bullet cam that has >400 line resolution with a varifocal lense.
 
Transmission over a few hundred feet requires an FCC license. Those units will be very expensive.

I looked at the link, I think 1.2 Ghz is the microwave oven frequency, so yu may not need a license, but could get interference from nearby ovens. Two miles range is if you are on a mountain top, buildings, trees, etc will tend to block the signal.
