Operating the AXIS 250S

23

Exactly how much pre-trigger recording will be produced depends mainly on the bit rate setting. A high-quality video stream will occupy more of the internal memory and thus shorten the duration of the recording. The length of the pre-trigger recording in seconds can be roughly calculated by dividing 16 by the bit rate in Mbit/s.

Important!

Note that pre-trigger recording must be enabled in the video settings if you wish to use pre-trigger recording in event types.

Audio

The AXIS 250S provides a fully synchronized audio stream at up to CD quality. The following settings are available:

•Quality - Select the bit rate and sample rate to use. Generally speaking, the higher the setting, the better the sound quality, but at the higher levels the difference might not be audible. The default value (128 kbps) provides good quality sound.

•Volume Settings - The Master volume control should not normally need any adjustment. How- ever, if you are using some other audio input device on the Line connector, and the audio level is not satisfactory, then this level may need to be changed. Configurable between -30 and 30 dB.

•Mic input sensitivity - This setting should be set according to the specifications for the con- nected microphone. If the correct setting is used, there will be no need to adjust the Master volume level. The volume slider in the web interface will suffice for raising or lowering the vol- ume when viewing the video stream. If you are unsure of the correct setting for your micro- phone, try both settings.

•Audio Input - Select the input to use for the audio input. The options are:

•Line - connects other audio input devices

•Mic - connects a standard microphone

Port Status & Devices

Port Status

Clicking this link will display a list showing the status for the 4 inputs and the 1 output. The inputs cannot be configured here - this must be done from the System options, which requires administrator access.

If an input or the output has not been enabled by the administrator, then the port will be shown as “Not in use”.
