SZBJ IR Repeater，IR Remote Control Extender，Infrared Repeater System

I was hoping for this to work, but the unit I got must have been defective. The receiver head and the control unit blinks when I press the remote. However, none of the emitters were working. Called Amazon tech support and they walked me through diagnostics using the camera to see if it detects any IR signals being detected from the emitters. Since none of the three emitter heads produced a signal, I think the control unit is bad. So, returning it.

Does just as wanted
