AXIS M1145–L Network Camera

Setting Up the Product

Gain, measured in decibel (dB), is the amount of amplification applied to the image. A high gain may provide a better image in low light situations but will increase the amount of image noise.

Set Gain to

Auto to set the gain automatically. If required, use Max gain to limit the applied gain.

Fixed to use a fixed gain.

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.

Iris configuration

Iris configuration shows the current configured iris type. Do not change the iris configuration unless the lens has been changed, see .

Iris adjustment

Select Enable automatic iris adjustment to automatically compensate for changing light conditions. This option is not available if a fixed iris is used.

Use the Iris adjustment slider to set the preferred F-value. The scale represents the amount the iris is open. If set to 0, the iris is opened as much as possible. If set to 100, the iris is closed as much as possible. The actual F-value is shown below the slider. If automatic iris adjustment is enabled, the iris will stay at this position as long as light conditions are favorable. If light conditions change, the iris will adjust itself to the best iris settings. If automatic iris adjustment is disabled, the iris will lock on the set position regardless of light conditions

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 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

CAUTION

Do not look directly into the IR LED at short distance. Since the IR light provided from the IR LED is powerful light outside of the visible range, please use the camera to check if IR light is activated or not.

The IR illumination can be activated or de-activated, and its intensity can be increased or decreased by moving the slider, from the product’s Live View page. Other settings can be defined from Setup > Video > Camera Settings.

De-select the Enable IR illumination option to disable IR illumination altogether. If you disable the Synchronize IR illumination with day/night option, IR illumination will not be synchronized with day/night changes.
