Has anyone tried a Lamson HS4320A? I saw one at Home Depot and it looked interesting. 30ft range,60degree FOV already wired for 9v,$14.97, and has a siren/chime mode.The 60 degree feature is what sounded the best. I thought it might reduce the number of butt/nose pics. I know very little about electronics so I was leary to start playing with it. If I tried to use it and it is not compatible what is the worst that could happen?
