I'm also having this same problem with outdoor dome cams at a client's location. Have cleaned domes and lenses twice. The manufacturer's tech support suggested I change the viewing angle saying that when it is too far one side or the other it can cause the IR sensors to be too far from the dome and cause bounceback. However, changing the angle did nothing. What model cams are you working with? The ones I'm working with are IC Realtime ICR-650-VD.
