1Introduction

The V-Mic is a hardware and software solution for the recording of

audio, coming from a microphone. The supplied hardware unit can

operate stand-alone and has a built-in microphone, but can also be

connected to a professional external microphone. The recorded data is

stored digitally onto an SD card and is sent optionally over the network,

in which case the data is wrapped into a special Tunnel-format that can

be received by the Call Recorder Apresa or by the V-Archive software

running on a Windows PC. The external Apresa recorder or V-Archive

software can both interpret the Tunnel-format and make playable audio

files from it, together with the original date and time of recording.

The use of an SD card is mandatory and must be FAT32 formatted. The

recorded data is stored in WAV file format on the card. Depending on

whether a Tunnel has been defined or not, the files are sent over the

network or can be read later by the V-Archive software.

The V-Mic can operate completely stand-alone and when the capacity of

the SD card is big enough, it can store data for days or even weeks.

Connection to the V-Mic is made with a network cable or by using Wi-Fi.

The web interface can be accessed by using a standard browser. The

cable must be connected to the Ethernet port (100 Mbps, Full-Duplex).

The V-Mic is a member of a family of compatible products that can be

used to create all sorts of recording solutions. There are V-Taps for VoIP,

Analog and ISDN telephony and there is a V-App for mobile recording.

All of these products will communicate with the Apresa Corporate or

Apresa Cloud-based recording solutions.

The V-Mic needs to be powered through a 12V DC plug, or a USB cable

or a LAN cable with PoE.

A FAT32 formatted SD card must be inserted to store the recordings.

2Getting started

2.1 Hardware installation

The V-Mic is out-of-the-box ready to use:

•Insert an SD card (up to 32 GB, FAT32 formatted).

•Connect a 12V DC plug, USB or a LAN cable with PoE for power.

•Wait for the red light to go off.

(By default, the V-Mic records from its internal microphone.)

•Press the button to start recording; the green light goes on.

•Press the button to stop recording; the green light goes off.

•The recorded audio is now stored in a WAV file on the SD card.

To fine-tune the audio settings or to setup a connection to external

software, you have to access the settings in the web interface. Then it is

needed to connect with the network, using a browser (see here).

2.2 Software installation

External software can be used to receive the recorded audio files that

are produced by the V-Mic, and to archive them into a database. The

files are sent via a special Tunnel protocol, that must be setup in the

web settings page of the V-Mic. The Tunnel data stream can be send to

the Call Recorder Apresa or the V-Archive software.

2.2.1 Call Recorder Apresa

The Call Recorder Apresa is recorder software running on the Linux

Debian operating system. The Apresa can receive Tunnel data from the

V-Mic, convert this data into audio files and store these into its own

database.

The Apresa can receive multiple streams from many V-Mic and V-Tap

units simultaneously. In that case, the recordings of different locations

are centrally stored in one database.

To setup the Apresa to act as a Tunnel server for a V-Mic (or V-Tap), go

to System settings, Network tab and enable ‘V-Tap’as is shown below:

NOTE: The IP address of Apresa is the “External Storage IP” in the V-Mic.

2.2.2 V-Archive software on a PC

The V-Archive software for the PC can, just as the Apresa, receive audio

files via a Tunnel from the V-Mic unit, and store these files into its own

database. The V-Archive software can also receive multiple data streams

from different V-Mic and V-Tap units simultaneously.

Note: During installation of V-Archive, the V-Mic needs to be connected

once to a USB port on the same PC.

To setup the V-Archive software to accept connections from a V-Mic, go

to Options, Setup, Recording tab and enable ‘V-Tap connections’:

NOTE1: The PC’s IP address is the “External Storage IP” in the V-Mic.

NOTE2: Be sure that the PC’s firewall is open for TCP port 2016, the

default “External Storage TCP Port” in the V-Mic unit.

The V-Archive installer will try to do this automatically.

NOTE3: The V-Archive software does not need licenses to receive from

the V-Mic unit.

The V-Archive software for the PC is further not described in this

manual; see for more details the V-Archive manual.

2.3 Checklist for Tunnel connection

A connection between V-Mic and Apresa or PC software is needed to get

the recorded data automatically into a user accessible database.

The following checklist can be used to setup this Tunnel connection:

1) Install the Hardware, and note that, only during installation of V-Archive,

the V-Mic needs to be connected once with USB to the same PC.

2) Install Apresa or V-Archive PC Software and enable V-Tap connections.

3) Get access to the V-Mic over the network by opening the settings page in a

browser. This can be done with a network cable or with Wi-Fi.

4) On that page, the IP address of the Apresa or the PC with V-Archive must be

entered as the “External Storage IP Address”and the “External Storage via

Tunnel”must be enabled.

5) Any firewall must have a rule that makes it possible to receive from TCP port

2016, the default “External Storage TCP Port”. This tunnel port number can

be changed, when needed.

During installation of V-Archive this port is automatically opened, when this is

allowed by the PC.

6) To see if the PC receives something from the V-Mic, it is possible to make a

network trace for test purposes.

In V-Archive, go to menu Actions and select ‘Network trace’, press Start, make

a short recording by pressing the button twice, wait 20 seconds, press Stop

and then Save. From the zip file 'tunneltrace.pcap' can be analyzed with

Wireshark.

The Apresa recorder has a similar option to make a network trace in menu

Tools, System.

7) The SD card in the V-Mic should contain “.WAV” files. The SD card can be

read by the V-Archive software in menu File and ‘Import from V-Tap’.

The WAV files can also be opened by explorer on a PC with audio playback.

3Web interface and Settings

There are two ways to access the web interface of the V-Mic:

1) With a network cable, connected to the LAN. See below.

2) With Wi-Fi, after putting the V-Mic in a special ‘config-mode’,

see Access Settings with Wi-Fi.

3.1 Access with a network cable

In the case of using a cable, DHCP is default enabled and the V-Mic can

be accessed with a browser by entering the address:

http://vmicXXXXXX.local

XXXXXXis the serial number, as it is found on the bottom of the device.

Note: It may take some time after first connect before the local name is known to the network.

When this does not work, the MDNS protocol is probably not active on

the network. The IP address, given by the DHCP server (if present), may

then be difficult to track down. Then, the best way is to set a static

(fixed) IP address, by using an SD card:

Defining a Static IP address with an SD card:

. Create a text file on your PC, named “IP”.

. The first line in this file must hold the IP address.

. Copy “IP.TXT” to the root-directory of an SD card.

. Insert the SD card into the V-Mic unit.

. The IP address has now changed and can be accessed.

. The file “IP.TXT” is deleted from the card by the V-Mic.

3.2 Web settings page

After entering the IP address in your browser, the settings page of the

V-Mic appears, as is shown on the next page.

By pressing the Submit and Restart button, the settings are saved by the

V-Mic and the unit restarts. Any ongoing recording is stopped, the file

on SD is closed, and after a few seconds the new settings are activated.

3.3 Settings

The settings are divided into groups that are described in the following

paragraphs.

3.3.1 V-Mic Information

Name of this V-Mic

A custom name for this V-Mic. For example "Meeting_room". This

name will show up on the tab "Local ID" when using V-Archive or

Apresa. The maximum length for the name is 16 characters.

Ethernet IP Address

The Ethernet IP address to access this V-Mic when using a LAN cable.

When the ‘Ethernet IP Mode’is on DHCP, the IP address is obtained

from the server.

The field is blank when the V-Mic has no Ethernet IP address.

Wi-Fi IP Address

The IP address when the V-Mic is connected with Wi-Fi to a router or

other access point. Fill in the Wi-Fi settings below.

Ethernet MAC Address

The Media Access Control (MAC) address of each device operating on

an Ethernet network is an unique identifier that is needed to route

the packets over the LAN. This address cannot be changed.

Wi-Fi MAC Address

The unique Wi-Fi MAC address that cannot be changed.

Serial Number

The serial number can also be found on the bottom of the case of

the V-Mic.
