You might also get an IR emitter and mount it on the roof eaves on the driveway end of the house. That will really help illuminate the driveway and sideyard with IR without having to turn the camera IR up so much that you get that glare off the bushes. In fact, you might get two while you are at it and mount one closer to the camera. That way you can let the external illuminators handle everything and you can turn the camera IR off. Just pay attention to the angle the illuminator will throw the
IR light. Some are narrow (like 30 degrees) and that wouldn't be wide enough for your application.
