Video and Audio

Local Contrast applies contrast to a specific area of the image. Use the slider to adjust the contrast, where a higher value produces an image with high contrast between the dark and light areas.

White Balance

White balance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis product can be set to automatically identify the light source and compensate for its color. Alternatively, select the type of light

source from the drop-down list. For a description of each available setting, see the online help.

The white balance window is enabled for the Automatic and Automatic outdoor options that appear in the White balance drop-down list. Select one of the options from the drop-down list to set the white balance window properties. Select Automatic to use the default settings for the Automatic and Automatic outdoor options (in the White balance drop-down list). Select Custom to manually set a reference window for white balance in the view area.

Exposure Settings

Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth considerations.

Exposure value - Click in the bar to fine -tune the exposure.

Exposure control - This setting is used to adapt to the amount of light used. Automatic is the default setting and can be used in most situations. The shutter speed is automatically set to produce optimum image quality. Flicker-free 50 or 60 Hz is used to remove flicker which can be caused by fluorescent and other light sources. The Hold current option locks the current exposure settings.

Enable Backlight compensation - Enable this option if a bright spot of light, for example a light bulb, causes other areas in the image to appear too dark.

Exposure zones - This setting determines which part of the image is used to calculate the exposure. For most situations, the Auto setting can be used. For particular requirements, select a predefined area.

Shutter & Gain

The shutter and gain settings affect the amount of motion blur and noise in the image. To adapt to different lighting, available storage space and bandwidth, it is often necessary to prioritize either low motion blur or low noise. The Axis product allows using different prioritization in normal light and in low light.

Shutter speed is related to the amount of time the shutter is opened and is measured in seconds (s). A slow shutter speed allows more light to reach the sensor and can help produce a brighter image in low light situations. On the other hand, a slow shutter speed can cause moving objects to appear blurry.

Set Shutter to

•Auto to set the shutter speed automatically. If required, use Max shutter to limit the shutter speed to prevent the frame rate from being reduced. For example, to get 30 fps, set Max shutter to 1/30.

•Fixed to use a fixed shutter speed.

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.

F44 specifications

Axis Communications has long been a leader in the field of network cameras, and its F44 series exemplifies this commitment to innovation and quality. The Axis F44 is designed primarily for surveillance and security applications across various environments. This camera's unique modular design allows for flexibility in installation, adapting to diverse user needs and specific site requirements.

One of the standout features of the Axis F44 is its dual-channel capability. This means it can support two separate camera heads, allowing users to monitor different areas simultaneously while using a single video management system. This flexibility not only saves costs in terms of installations but also maximizes coverage without needing multiple standalone cameras.

The F44 series is equipped with Axis's advanced Lightfinder technology. This feature ensures exceptional image quality even in low-light conditions, making it ideal for night surveillance. With its wide dynamic range (WDR), the F44 can capture details in complex lighting situations, such as brightly lit areas next to shadowed regions. The result is clear and balanced video footage, crucial for identifying potential threats or intruders.

Another highlight is the camera’s support for Axis Zipstream technology. This advanced compression algorithm optimizes bandwidth and storage usage without compromising video quality. By analyzing the scene and selectively compressing different regions of the video stream, Zipstream ensures essential details remain clear while reducing the overall file size. This is particularly beneficial for systems with limited bandwidth or storage resources.

The F44 also emphasizes user-friendly features, including remote configuration and management capabilities. This allows security personnel to make adjustments without being on site, saving both time and resources. Furthermore, the camera is built with an array of analytics tools that can be integrated into existing systems for enhanced functionality. These include motion detection, tampering alarm, and video analytics features which can be customized based on specific security needs.

In terms of construction, the Axis F44 series is robust and designed for durability. It is compliant with various weather-proofing standards, making it suitable for outdoor installations in various climatic conditions. The camera can also be outfitted with various lens options depending on the specific use case, further increasing its versatility.

In conclusion, the Axis F44 combines advanced imaging technologies, flexible installation options, and robust construction, making it an excellent choice for security professionals seeking reliable and high-performing surveillance solutions. Whether for urban or rural applications, the F44’s blend of features ensures it meets diverse surveillance requirements effectively.
