AXIS F44 Main Unit

Video and Audio

Simplex — Network Camera speaker only - Audio is transmitted from a client to the Axis product and can be played by a speaker connected to the product. To transmit audio using the Live View page, the Talk and Microphone buttons must both be active, see AMC Audio Controls on page 12.

Simplex — Network Camera microphone only - Audio captured by the product microphone is transmitted from the Axis product to one or more clients.

To set the audio mode, go to Video & Audio > Audio Settings and select the desired mode from the Audio mode drop-down list.

Audio Input

An external microphone or a line source can be connected to the Audio-in connector. Configure the audio input settings under Video & Audio > Audio Settings.

Select Microphone to use an external microphone or Line to use a Line in device, e.g. an audio mixer for multiple microphones or a microphone with a built-in amplifier , as audio source.

The Microphone power option provides DC power for an external microphone. Microphone power should only be used with microphones that have no battery. This setting should not be enabled when using a dynamic or battery powered microphone.

Use the Input gain to control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to amplify the sound. If the sound is too high, choose a lower dB. The Level bar gives a visual representation of the audio signal level in dB relative to the full-scale input level.

•Green — the signal is at a good level.

•Yellow — the signal is becoming distorted.

•Red — the signal is distorted.

Use the Encoding option to select digital audio encoding format.

•AAC requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec. If achieving the best possible audio quality is a priority, AAC is the recommended codec to use. An AAC license is included in the Axis product.

•G711 is an unlicensed standard codec that is useful when integrating audio into a VoIP system

•G726 is an unlicensed speech codec that is most commonly used within the security industry.

Note

If recording audio to edge storage, such as an SD card or network share, use AAC encoding.

The Sample rate defines the number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but also requires a greater bandwidth.

Set the required Bit rate depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit rate may have latency or delay, but will require less bandwidth.

For more information about these settings, please see the online help .

Audio Output

An external speaker can be connected to the Audio-out connector (a built-in amplifier is required for this). The output can be connected to another amplifier with speakers. A stereo connector must be used for the audio out.

Configure the audio output settings under Video & Audio > Audio Settings.

Output gain - Control the volume (dB Full Scale) of the line audio output. If the sound is too low, choose a higher dB. If the sound is too high, choose a lower dB.

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.
