AXIS P1344-E Network Camera

Video and Au dio

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-Talk mode, 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 A X IS Media Contro l on page 16).

Simplex - Network Camera speaker only - Audio is transmitted f rom the client to the Axis p roduct and played by the speaker

connected to the product. To send a udio, 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

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 E nab le 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 a nd 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 representa tion of the au dio 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 a nd most widely used codec.

If achieving the best possible audio qua

lity is a priority, AAC is the recommended codec to use. An AAC license

is included in the Axis product.

• G711

• G726

Sample rate - The number of times per second the sound is sampled. A higher sample r ate will provide b etter audio quality, but

also requires a greater bandwidth.

Bit rate

- Set the required bit rate depending on the selected encoding. A higher bit ra t e will give better audio quality. A lower bit

rate may have latency or delay, but will require less bandwidth.
