If your Defender DVR remote control is not working, make sure the batteries are installed correctly and that you are pointing the remote at the IR sensor. Point the IR Remote at the camera lens and press a button. You should be able to see the IR LED flicker through the DVR monitoring device. You may also want to try replacing the batteries in the remote.
