AXIS Q1765–LE PT Mount Network Camera
Video
When Shutter and Gain are both set to Auto, it is possible to set the Priority between low motion blur and low noise manually and to use a different Priority in Normal Light and in Low Light.
Example
Consider an area where people or vehicles move during the day, but where there should be no movements during night. To be able to, for example, recognize faces or license plates, move the normal light priority slider toward low motion blur. At nighttime, motion detection is more important than identification. Motion blur is acceptable and since low light can cause a lot of noise, move
the low light priority slider toward low noise.
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noise and produce smaller image files.
Day/Night
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 external 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 filter is off.
If using automatic Exposure control, set the IR cut filter to Auto to automatically switch between On and Off according to the lighting conditions.
The camera lens is IR corrected, which means that it maintains focus in mixed light, however a small focus adjustment is recommended when IR illumination is used. Select Enable focus adjustment for IR illumination to automatically adjust the focus when the IR cut filter switches between on and off.
The Day/Night shift level bar helps determine when the camera will shift from day mode to night mode. Normally, the camera automatically changes mode from day to night when very dark (level 100 in the slider). By setting Day/Night shift level to a lower value, the camera will change to night mode earlier.
Built-in IR Illuminations LEDs
WARNING
Risk of eye injury. Do not look directly into the IR LED at short distance. Since the light provided from the IR LED is outside of the visible range, it is not possible to see if it is active. Use the camera to check if the IR illumination is active.
The IR illumination can be activated or
Overlay
Overlays are used to provide extra information, for example for forensic video analysis or during product installation and configuration. Overlays are superimposed over the video stream.
An overlay text can display the current date and time, or a text string. When using a text string, modifiers can be used to display information such as the current bit rate or the current frame rate. For information about available modifiers, see File Naming &
Date/Time Formats in the online help 
.
To enable overlays:
1.Go to Video > Video Stream and select the Image tab.
2.To include an overlay image, select Include overlay image at the coordinates. The overlay image must first be uploaded to the Axis product, see Overlay Image.
3.To include date and time, select Include date and Include time.
