AXIS Q1604–E Network Camera
Video and Au dio
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noi se a n d pro duce sma ller image files.
IR cut filter
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example at night, or
when using an IR lamp, set the IR cut filter to Off. This increases light sensitivity and allows the product to “see” infrared light. The
image is shown in black and white when the IR cut filte r is off.
If using automatic Exposure control,settheIRcutfilter to Auto to automatically switch between On and Off accordingtothe
lighting conditions.
Overlay
Overlays can be used to provide extra information and are superimposed over the video image. With overlay text it is possible to
include date and time or view the current bit rate as overlay text.

box option, and enter the overlay code in the field. See the online help

indicates if they are enabled.

Focus
You can focus the Axis product under Video & Audio > Focus. For most app lications, 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.

pixels in an area of the image, for example to ensure that the image size fulfills specific requirements. To position the pixel counter,
click o n the text and drag the window to the desired posi tion.
