Privacy Mask

A privacy mask is a user-defined area that prevent users from viewing parts of the monitored area. Privacy masks appear as blocks of solid color or blurred image elements and are applied on the video stream. Privacy masks cannot be bypassed using the VAPIX® application programming interface (API).

The Privacy Mask List (Video & Audio > Privacy Mask) shows all the masks that are currently configured in the Axis product and indicates if they are enabled.

You can add a new mask, re-size the mask with the mouse, choose a color for the mask, and give the mask a name.

For more information, see the online help

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 15.
