I have to install a CCTV camera which is almost 700 meter far from the DVR and monitor.is it okay if i use a CAT5 UTP wire? will i use a video balun? how about the power supply? can you help me with this sir.

and another thing sir. i will put the camera at the electric post,so where can i get a 12 volt current to my camera for it to work?

so it is advisable for me to use a wireless camera for that distance sir? coz somebody told me that wireless cameras are hard to use.they are more susceptible to interference and a lot more expensive.can you advise me with this sir? tnx.
