So currently I have 2 cameras on my network and I am going to be adding 2 more. The existing 2 cameras I have one placed indoors to watch the garage and then one on the exterior of the garage to watch the driveway. I am going to be replacing the driveway camera with a better camera and then putting the existing drive way camera on the other corner of the garage to view the gate. My question is, could I get away with using a splitter between the two cameras instead of having to run a whole new wire? If so what would be recommended. The 4th camera will be added to the front door of the house witch will be in a seperate location that will require a wire pull.
