Live IP/Analog camera using active video baluns

Hi

I have a project on my hands. Need some advice

I want to put a camera(preferably analog) and view & record what it see at a distance of 1.5 - 2 kms. Now, for some reason(which i will not get into here) i am not goin to use a wireless system. Its gonna be wired. This is what i have in mind:

1. Place an analog camera --> BNC connector --> Active video balun ---> UTP CAT 5 cable ---> another video balun ---> TV monitor

Now the following queries:

1. Will a balun increase the range and help me cover the distance of 1.5 - 2 km without too much attenuation of signal strength?
If Yes - then can someone recommend a good quality video balun (brand) which i can purchase or order in India
If No - What other way to cover the distance?

2. Can the camera be powered up through the baluns ( i mean supplying power through the UTP cable using one or more pairs in the cable)

3. If i choose to use a IP PTZ camera, can i use these baluns then?
If not - then how do i increase the range over which the CAT5 cable will take the signal (i presume a UTP cable can be used for not more than 100-150 mtrs)

4. If yes then is it possible for me to control the PTZ through these baluns

5. Any other alternatives are also welcome !!

1. Don't think so. Probably its just a signal transformer/balancing hardware

2. You probably don't need baluns if you're going to use UTP cables (or ethernet cables). If your camera supports it, it can be powered by PoE (you may need an injector if your router doesn't inject power into the cable)

3. Connect multiple to switches

4. Not sure. You could with a web browser if it used the UTP/ethernet cables

5.1. Use the internet instead.
