A camera service port has an automatic termination for connecting to a near-side monitor. The camera service includes an audio jack and a phone jack. The audio jack includes first and second terminals for receiving signals from a camera and connecting to the near-side monitor. The phone jack includes a first connector coupled to the camera, an equivalent resistor coupled to the first connector, and a second connector coupled to the camera. The second connector is flexible to connect to the first terminal without being connected to an equivalent resistor. When the audio jack is plugged into the phone jack, the first terminal is coupled to the second connector and the second terminal is coupled to the first connector for receiving the signal from the camera. When the audio jack is not plugged into the phone jack, the equivalent resistor is coupled between the second connector and the first connector.
