AXIS Q1656 Box Camera Series
The device interface
Lock aperture
: Turn on to keep the aperture size set by the
Aperture
slider. Turn off to allow the camera to automatically
adjust the aperture size. You can, for example, lock the aperture for scenes with permanent light conditions.
Aperture
: Use the slider to adjust the aperture size, that is, how much light passes through the lens. To allow more light
to enter the sensor and thereby produce a brighter image in low-light conditions, move the slider towards
Open
. An open aperture
also reduces the depth of field, which means that objects close to or far from the camera can appear unfocused. To allow more of
the image to be in focus, move the slider towards
Closed
.
Exposure level
: Use the slider to adjust the image exposure.
Defog
: Turn on to detect the effects of foggy weather and automatically remove them for a clearer image.
Note
We recommend you not to turn on
Defog
in scenes with low contrast, large light level variations, or when the autofocus is
slightly off. This can affect the image quality, for example, by increasing the contrast. Furthermore, too much light can
negatively impact the image quality when defog is active.
Optics
Temperature compensation
: Turn on if you want the focus position to be corrected based on the temperature in the optics.
IR compensation
: Turn on if you want the focus position to be corrected when IR-cut filter is off and when there is IR light.
Calibrate zoom and focus
: Click to reset the optics and the zoom and focus settings to the factory default position. You need to
do this if the optics have lost calibration during transport, or if the device has been exposed to extreme vibrations.
Stream
General
Resolution
: Select the image resolution suitable for the surveillance scene. A higher resolution increases bandwidth and storage.
Frame rate
: To avoid bandwidth problems on the network or reduce storage size, you can limit the frame rate to a fixed amount.
If you leave the frame rate at zero, the frame rate is kept at the highest possible rate under the current conditions. A higher
frame rate requires more bandwidth and storage capacity.
Compression
: Use the slider to adjust the image compression. High compression results in a lower bitrate and lower image quality.
Low compression improves the image quality, but uses more bandwidth and storage when you record.
Signed video
: Turn on to add the signed video feature to the video. Signed video protects the video from tampering by adding
cryptographic signatures to the video.
