that it toggles between the speaking and listening modes.

•When selecting Simplex - Network Camera speaker only mode, the speaker con- nected to the camera plays audio, but no audio is transmitted from the camera to other web clients. This could be used for providing spoken instructions to a per- son seen in the camera. This mode requires you to use the push-to-talk button.

•Simplex - Network Camera microphone only mode transmits audio from the AXIS 233D to web clients. It will not receive audio from any other web client. This can be used in remote monitoring, and web attractions, to provide live audio, as well as video of a monitored situation.

When using Half-Duplex, the option Send the sound from the active client to all other clients, transmits the audio signal from the client that is talking to all the other clients.

Audio Input

Audio from an external microphone or a line source can be connected to the Audio in Power/Audio connector of the AXIS 233D, see I/O terminal connector blocks, on page 58. The audio source must be set to Microphone or Line depending on the connected device.

When Microphone is selected as a Source, set the Input sensitivity to High for a passive (unamplified) microphone, for example a computer mic or clip-on mic. Set to Low for a microphone with a built-in line amplifier.

The Enable microphone power option provides DC power for an external microphone. If using a small electret condenser microphone such as a clip-on or PC microphone, this option needs to be enabled.

Note: To use a high impedance dynamic microphone, DC power should be disabled. DC power will not harm the microphone, but if you are uncertain, try switching it off and on. The default value is DC power enabled. To use a professional microphone requiring 48V phantom power, you need an external power supply and you must use a balanced-unbalanced converter (audio transformer) in-between.

If there are problems with the sound input being too low or high, adjust the input gain for the microphone attached to the AXIS 233D.

Select the desired audio Encoding format; G711 or G726.

Depending on the selected encoding, set the desired audio quality (Bit rate). The settings depend on the available bandwidth and the required audio quality.

The AXIS 233D can be set to trigger an event if the incoming sound level rises above, falls below or passes the set value. The Alarm level is set between 0-100%.

Audio Output

If the sound from the speaker is too low or high, adjust the output gain for the active speaker attached to the AXIS 233D.

When satisfied with the settings, click Save. Click Reset to revert to the old settings.

Note: To receive synchronized video and audio, it is recommended that the time settings in the camera and client PC are synchronized with an NTP Server. This is enabled in the camera under System Options > Date & Time. Please refer to the online help pages for more information.

233D specifications

Axis Communications, a pioneer in the field of network video solutions, has continually pushed the envelope in surveillance technology with its innovative products. Among its esteemed offerings, the Axis 233D stands out as a formidable tool for both security professionals and organizations seeking comprehensive monitoring solutions.

The Axis 233D is a high-performance PTZ (Pan-Tilt-Zoom) network camera designed for demanding surveillance environments. One of its main features is the ability to provide high-resolution video streaming at 30 frames per second, ensuring that users can capture clear and detailed images, even in dynamic situations. This camera supports a resolution of up to 2 megapixels, which enhances its ability to deliver crisp visuals, crucial for identifying individuals and objects in the monitored areas.

Equipped with advanced pan, tilt, and zoom capabilities, the Axis 233D can cover expansive areas with ease. The camera offers a 360-degree endless rotation for pan movements and a wide field of view, making it ideal for large spaces like parking lots, shopping centers, and public transport stations. The powerful zoom lens allows operators to focus on specific subjects from a distance, which is essential in security monitoring.

The Axis 233D also employs robust technologies to ensure excellent performance in various lighting conditions. With integrated WDR (Wide Dynamic Range), this camera can balance scenes with significant contrasts in lighting, ensuring that both bright and dark areas are clearly visible. Additionally, features like digital noise reduction contribute to clearer images in low-light situations, making it versatile for day and night operation.

Another characteristic that sets the Axis 233D apart is its network functionality. This camera supports Power over Ethernet (PoE), simplifying installation as it requires only a single Ethernet cable for both power and data transfer. It also leverages Axis' advanced video compression technologies, including H.264, which optimizes bandwidth usage while maintaining high image quality.

Furthermore, the Axis 233D is embedded with intelligent video analytics, enabling proactive monitoring. Functions such as motion detection and object tracking help users respond quickly to potential security threats. This capability is critical in real-time environments where each moment counts.

In summary, the Axis Communications 233D is a high-end surveillance solution that marries advanced technology with user-friendly features. With its PTZ functionalities, exceptional image quality, robust performance in varying light conditions, and intelligent analytics, it serves as an indispensable asset for security professionals looking to enhance their surveillance systems effectively. As security needs continue to evolve, the Axis 233D remains at the forefront of addressing those challenges.
