2.5 Connect to Speaker
The video audio and power are traveling through a single cable. There is a splitter cable that will separate video audio and power at the other end of 20 meters cable. The video will go to the HDMI convertor, eventually output the HDMI TV. The power terminator can take the power from the DC12V adaptor and supply the power to the camera.
It is important to understand the audio never goes to the HDMI converter. The audio will need to be connected to an external speaker. The RCA to 3.5mm adaptor is included. It works with most external speakers.
If you have experience the rolling bar on the monitor after adding an external speaker, the power source of your external audio may have introduced the noise to the camera. Please change the power adapter of your speaker.
