Switches & connectors

DIP switch - A corresponding line termination switch is supplied for each video input. All units are shipped with line termination enabled for each video input; that is, with the DIP switch set in the down position.

Note: If the video source is to be connected in parallel with other equipment, disable the input termination by turning the corresponding DIP switch to the up position (OFF). Failure to do so may cause reduced image quality.

Control Button - Press this button to restore the factory default settings, as described in Resetting to the factory default settings, on page 56. This button is also used to install the video server using AXIS Internet Dynamic DNS Service (See the Axis Video Server Installation Guide).

Video Input - Each supported video input (1 or 4 depending on the model) is connected using a coax/BNC connector. Physical connections made using a 75 ohm coaxial video cable have a recommended maximum length of 800 feet (250 meters).

Line Out - Mono audio output (line level), which can be connected to a public address (PA) system or an active speaker with a built-in amplifier. A pair of headphones can also be attached.

Line/Mic In - Single 3.5 mm input for a mono microphone, or line level mono signal (only the left channel is used from a stereo signal).
