Thanks Scorpion for all your words of wisdom.I am an electrician so i have the concept of fishing wires and wiring,i just know nothing about cctv.What is a good facial recognition bullet camera that would fit into my budget?Four of the cams are for my front door,driveway,and both side entry gates.The other 3 are just coverage area cams that will each view an area of the backyard around 30-40'.
