Hi, I am new here and stumbled unto this helpful site. need some advice. please bear with my questions. I am renovating my new home and intend to install a few cctv cameras around the house. With some reading, i found out that cctv cameras can use either coaxial or cat5e cables. 1) should i use coaxial cables and install an electrical outlet next to the cameras? if yes, what type of coaxial cable is best used? 2) use Cat5e cables and install an electrical outlet next to the cameras? 3) use cat5e cables and use passive baluns? with passive baluns, I don't need direct power at the cameras? Can I just use the baluns to feed power to the cctv via cat5e cabling? either one is fine with me just as long it's reliable, convenient and upgradable in the future. thanks alot!

Thanks guys. Cleared up some queries that i had. Think I will go with Cat5e then, since i'm getting a box of it for LAN cabling around the house. Should have enough remaining for the cctv. One thing that I still don't know is power supply to the cctv. Please bear with my questions again. With the passive baluns, I can connect the output of the camera into it and the output is the cat5e. and on the DVR end, it's the way around to convert it back to coaxial? what about for the power if i want to use cat5e to feed power to the cctv? All i need is a distributed fused power supply box? the twisted pair wires directly connects to it? is this the only way to supply power to the cctv cameras? thanks again.
