The cameras are water proof but the wires are not. The wires go out easy because of the weather so they need to be installed inside of covered up completely. The wires are 50-100ft long. I had to buy three extensions. They are $17-20 a piece. The wires need to be ordered as well since the stores don't carry them. The extensions come with an adapter so that's good. And yes you can connect it to your monitor
