In order to set your IP camera up properly, and be able to access it from anywhere in the world, you will need some basic equipment. You will need a desktop PC, the wireless IP surveillance camera, some RJ45 cable and a wireless router. Internet connectivity equipment is all compatible as long as you are using PC-based equipment for your PC and Mac-based equipment for your Mac. Just check the packaging to make sure the equipment is compatible with your platform. Once you have confirmed that, the rest will fall into place.
If you are going to be installing your camera outdoors, then be sure to get a camera designed to handle the elements. You may also want to invest in rechargeable batteries to help cut down on the cost of running your camera.
