AXIS P1344-E Network Camera

Video and Audio

Half-duplex - Audio can be transmitted in both directions between the Axis product and the client computer, but only in one direction at a time. You must actively receive sound using the Talk/Listen button visible in the Live View page (see AXIS Media Control viewer toolbar). In Push-To-Talkmode, click and hold the button to speak and release it when done. In Toggle mode, click once to switch between speaking and listening. The Talk/Listen mode is configured from the Audio tab in the AMC control panel (see AXIS Media Control on page 16).

Simplex - Network Camera speaker only - Audio is transmitted from the client to the Axis product and played by the speaker connected to the product. To send audio, the Talk and Microphone buttons in the AMC toolbar must both be enabled. Click either button to stop audio transmission.

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

Audio Input

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

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

Microphone power - The Enable 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. Microphone power will not harm the microphone; if you are uncertain, try switching it off and on. To use a professional microphone requiring 48V phantom power, you need an external power supply and a balanced-unbalanced converter (audio transformer) in between.

Input gain - 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.

Encoding - 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.

•G726

Sample rate - 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.

Bit rate - 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.
