New to the security and camera world but this is something more down my ally! dual cameras facing the yard and the driveway. Wires run inside. Currently ordering the second one for the mount from Andy.
Nice work and a great deal of satisfaction thinking of it and creating it. It is obvious you are a fabricator. Usually though, when you want two cameras to cover an area, it is better to install them at the two far corners for less amount of blind spot. With your setup on that bracket, you end up with a blind spot in the middle, or less of a degree of vision if you turn them inward to not have the blind spot in the middle.
