AXIS 214 PTZ
•In Simplex - AXIS 214 PTZ speaker only mode, the speaker connected to the AXIS 214 PTZ will
play audio, but no audio will be transmitted from the AXIS 214 PTZ to other web clients. This
could be used to e.g. provide spoken instructions to a person viewed in the camera. This mode
requires the use of the push-to-talk button.
• Simpl
ex - AXIS 214 PTZ microphone mode transmits audio only from the microphone connected
to the AXIS 214 PTZ to web clients. It will not receive audio from other web clients. This can be
used in remote monitoring, web attractions etc., to provide live audio, as well as video, of a moni-
tored situation.
When using half-duplex, the Send the sound
from the active client to all other clients option 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 c
onnected to the Line/Mic In socket of the AXIS
214 PTZ. The audio source can be set to Microphone or Line. If you are using a microphone, the input
sensitivity can be set to High or Low. See Technical Specifications, on page
42 for the exact maximum
levels.
The Enable
microphone power option provides DC power for the external microphone. If you use a small
electret condenser microphone such as a clip-on mic or a PC microphone, this option needs to be enabled.
To use a high impedance dynamic microphone, DC power
should not be enabled. Using DC power will not
harm the microphon. The default value is DC power enabled. To use a professional microphone requiring
48V phantom power, you need an external power supply and 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 214 PTZ.
Audio Output
If the sound from the speaker is too low or
high it is possible to adjust the output gain for the active
speaker attached to the AXIS 214 PTZ.
When satisfied with the settings, click Sa
ve, or click Reset to revert to the previously saved settings.
Advanced Audio Settings
The Advanced Audio settings allow you to tune the external microphone connected to the AXIS 214 PTZ’s
connection module to suit your environment.
Enable speech
filter improves the sound quality when the microphone is placed close to the person talking
and can also help reduce background noise. The filter cuts the lowest and the highest frequencies. The
bypass frequency range is approximately 250Hz to 3700Hz (measured at -10dB cut-off break points).
