Audio Recording; Factory Default - Dedicated Micros d4 Installations Anleitung

Bandwidth limit
The bandwidth used by the D4 can be limited to prevent overloading on slower
networks. The D4 has a 10MB/s connection (10Base-T).
The maximum bandwidth that a D4 will use (5 users viewing images) is 6Mb/s so
any limiting over 60% does not affect the bandwidth used by the D4. The
maximum bandwidth used by one user is approximately 2.5Mb/s
If you want to limit the bandwidth used by the D4 to 1Mb/s set the bandwidth
limit to 10%.
Note: Restricting the bandwidth does not decrease the image quality, but the
update rate of the images over the network will decrease.
IP address, Subnet mask, Default gateway
A unique IP address and a subnet mask must be given to the D4 in order to
communicate with it over a network. On an existing network these are often
obtained from the network administrator. A Default gateway will be required if
the D4 is going to be viewed from a remote location, such as a WAN or dial-up
via a router.
Note: The D4 requires a Static IP address, even if it is connected to a dynamic
(DHCP) network.
PPP address
The PPP (Point to Point Protocol) address is used when a Hayes compatible modem
is connected to the D4. The PPP address must be entered into the Network Viewing
software or Web browser to view images when connected to the D4.
By default, the PPP address is 172.017.002.002 when the TCP/IP address is at its
default setting of 000.000.000.000. The PPP address cannot be changed directly,
but is changed automatically when the TCP/IP address is adjusted.

Audio recording

A single channel of audio can be recorded on the D4, use this menu to enable or
disable audio recording. Audio recording takes up a small amount of storage,
approximately 4KB/s, this is regardless of the record rate (PPS) of the video. When
audio is enabled the record time is affected, check the new record time in the
'Record Schedule' menu.
Note: The audio recording is linked to Camera input 1, i.e. audio is only recorded
when camera 1 is recording. Camera 1 must be displayed to play back audio.
IR Receiver
The Infrared remote control option can be enabled or disabled from this menu.
The remote control mimics the front panel control of the D4. The remote control
does not allow the configuration of the menus.
When the IR receiver is enabled the IR LED on the D4 is solid green, when it is
disabled the IR LED switches to solid amber. The LED flashing green signifies an
IR signal being received.
Please refer to Appendix 2 for details of using the remote control.
Timed expiry
The timed expiry option allows images to be only held for a selected number of
days or hours. Images on the disk which are older than this time are not accessed.
By default there is no timed expiry.

Factory default

Use this option to return all settings to the factory condition.
