Note
• The back focus (step 2) should only be reset if the camera has been focused previously.
• Set focus as precisely as possible using the focus puller on the lens (step 3) before starting the automatic fine-tuning
(step 4).
• If the camera is placed so that it is difficult to look at the image and move the pullers at the same time, you can use the
Focus Assistant to focus the camera; for instructions, see the Installation Guide supplied with the product.
Advanced
The tools on this page can be used to find the optimal focus position. Always open the iris before focusing and enable it when finished
focusing. Focus is measured in the part of the image covered by the Focus window. Use the mouse to move and resize the window
and then click Fine-tune focus automatically. If needed, click in the Focus position bar or on the arrows at the ends of the bar, to
further adjust the focus. The buttons < and > move the focus position one step in either direction. The buttons << and >> move the
focus position multiple steps in either direction. Clicking on the bar sets focus to that position. If the camera is not focused after
completing the above instructions, try the Full range focus scan. The scan, which can take several minutes, transforms the focus
position bar to a graph where peaks indicate the best focus positions. Click in the graph to set focus to the desired position.

Audio Channels

Select the type of audio transmission from the Audio mode: drop-down list (Video & Audio> Audio Settings). The different types are:
Full duplex - Simultaneous two-way audio allowing you to transmit and receive audio (talk and listen) at the same time. There is no
echo cancellation; if feedback loops appear, try moving the microphone or the speaker.
Half-duplex - Audio can be transmitted in both directions between the Axis product and the client computer, but only in one
direction at a time. You must actively receive sound using the Talk/Listen button visible in the Live View page (see
Control viewer toolbar
once to switch between speaking and listening. The Talk/Listen mode is configured from the Audio tab in the AMC control panel
(see AXIS Media Control on
Simplex - speaker only - Audio is transmitted from the client to the Axis product and played by the speaker connected to the
product. To send audio, the Talk and Microphone buttons in the AMC toolbar must both be enabled. Click either button to stop
audio transmission.
Simplex - microphone only - Audio captured by the microphone connected to the Axis product is transmitted from the product to
one or more clients.

Audio Input

An external microphone or a line source can be connected to the product's Audio-in connector. Configure the audio input settings
under Video & Audio > Audio Settings.
Source - Select Microphone for an external microphone or Line for a Line in device, e.g. an audio mixer for multiple microphones or
a microphone with a built-in amplifier.
Microphone power - The Enable microphone power option provides DC power for an external microphone. Microphone power should
only be used with microphones that have no battery and when using the internal microphone. This setting should not be enabled
when using a dynamic or battery powered microphone. Microphone power will not harm the microphone; if you are uncertain, try
switching it off and on. To use a professional microphone requiring 48V phantom power, you need an external power supply and a
balanced-unbalanced converter (audio transformer) in between.
