Video and Audio

Important

Adding many privacy masks may affect the product’s performance.

Focus

You can focus the Axis product under Video & Audio > Focus. For most applications, the adjustments on the Basic tab are sufﬁcient. If required, additional adjustments can be made on the Advanced tab. Before focusing, always click Open iris to open the iris to its maximum. This gives the smallest depth of ﬁeld and thus best conditions for correct focusing. Click Enable iris when ﬁnished focusing.

Basic

Follow the on-screen instructions on the Basic tab to adjust zoom and focus. The pixel counter is used to determine the number of pixels in an area of the image, for example to ensure that the image size fulﬁlls speciﬁc requirements. To position the pixel counter, click on the text and drag the window to the desired position.

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 Settings

The audio functionality for each video stream is enabled under Video & Audio > Video Stream > Audio.

Audio Modes

The Axis product supports the following audio modes:

Full duplex - Simultaneous two-way audio allowing the Axis product to transmit and receive audio 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 to and from the Axis product but only in one direction at a time. To transmit audio using the Live View page, use the Talk and Listen buttons, see AMC Audio Controls, on page 10.

Simplex — speaker only - Audio is transmitted from a client to the Axis product and can be played by a speaker connected to the product. To transmit audio using the Live View page, the Talk and Microphone buttons must both be active, see AMC Audio Controls, on page 10.

Simplex — microphone only - Audio captured by the product microphone is transmitted from the Axis product to one or more clients.

To set the audio mode, go to Video & Audio > Audio Settings and select the desired mode from the Audio mode drop-down list.

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.
