Folks, i just wanted to share the picture of the recent installation of a Barionet with the C-MOR video solution.

The photo nicely shows how the Barionet works as a central component of the video surveillance solution.
The IP based IO device does not only integrate sensors to trigger alarms, but also actors to activate visual and audible notifications.

Barionet can push notifications and alarms to iOS devices (iPhone)
icon4 04 14th, 2011| icon3Comments Off on Barionet can push notifications and alarms to iOS devices (iPhone)

A Barionet is a great product to monitor environmental parameters, power useage, contact closures etc.

If the Barionet detects an alarm condition, it will need to notify you. But how?

Sample code for sending email, operating a SMS modem etc is already available from us.

Here is a very nice method to do this via the popular iPhone by using an application called “prowl”. The Prowl makers operate a public server and manage the delivery to the iPhone/iPad/iPod touch “prowl” app via the standard iOS notification scheme (so, very little consumption of power/bandwith on the iOS device).
You need to purchase the prowl app from the app store ($2.99), register and generate an API key on the prowlapp website, and you are good to go!

On the Barionet, you will need a small application which
– opens a TCP connection to the prowl api server,, port 80 (http)
– sends an “add” command with a meaningful notification message to the server (see example below)
– close the connection.

That’s it!
The alarm message will arrive within very short time at your iPhone, where you can configure quiet times, alarm tones etc.

here is an example for a string you would need to send (replace the xxxxx… with the API code you get from the website):

“GET /publicapi/add?apikey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&event=alarm%20temp%3e65F%20too%20high&application=fridge HTTP/1.0” (plus 2x CR/LF)

Note: you will need to do the URL encoding (%20 for space etc) in your program if your message contains blanks or special characters.

We can provide a sample BCL program on request.


P.S: Once you have implemented this, let us know so we can feature your application!

SIP firmware for Barix IP Audio devices upgraded
icon4 03 14th, 2011| icon3Comments Off on SIP firmware for Barix IP Audio devices upgraded


there is a new application firmware out for the Barix IP Audio devices. SIP Client version v01.07 brings a major change intended to make the use of the devices much more easy.
The Web UI, through which the device is configured, now offers “profiles”, to allow easy configuration of different use cases

1) SIP phone
This profile is intended for applications on bidirectional devices, for applications which are similar or identical to a SIP phone. The Barix devices can be used ideally in call stations, help points etc, preconfigured numbers can be called using the contact closure inputs etc.

2) SIP paging endpoint with Background Music support
This profile works on all devices which provide output capability (all Exstreamer and Annuncicom devices) and is typically used for “IP Speaker” application or to drive a paging amplifier.

3) SIP door station
This profile enables typical door station functionality, is able to operate in automatic “half duplex” mode to support simple door intercom panels (Aiphone), and also allows to activate a relay via SIP Info/DTMF to open the door.

4) SIP gateway
An interesting “glueware” application, when this is selected, the device can work as a “SIP to standard Multicast RTP” converter, will serve as an endpoint, and re-broadcast (or multicast) the received audio stream so it can be used with any device which can play audio from a standard RTP stream.

5) SIP based audio monitoring
This mode is typically used for audio surveillance, covert operations, etc. In this mode, the device can establish a call silently to a configured destination if it picks up audio above a certain level.

The SIP application firmware now supports the PS16, the desktop IP paging station from Barix, and on the Annuncicom 155, even the microphone and speaker supervision are supported.

The firmware can be downloaded, as usual, from our website free of charge and devices can be updated via browser.

Exstreamer P5 – An IP Speaker without the Speaker ??
icon4 03 9th, 2011| icon3Comments Off on Exstreamer P5 – An IP Speaker without the Speaker ??


the Barix Exstreamer P5 now starts shipping. This very affordable IP Audio device is actually .. an IP Speaker. And at the same time, it is not .. the loudspeaker is missing.

IP Speaker from Barix

So … why ? What is the reason behind this ?

As we all know, architects want to have the choice of design, form and color if it comes to selecting a speaker. Installers need to pick a speaker with the right environmental specs. And the price, or a specific manufacturer, may be a decision criteria too for the selection of the speaker.

Other manufacturers offer “IP Speakers”. Such an IP Speaker limits the choices for the installer drastically, as the speaker design part is fixed, and eventually already installed speakers, which would be perfectly useable, need to be pulled out and replaced.

The Barix Exstreamer P5 solves this dilemma. It is EVERYTHING an IP Speaker needs to be, with the exception of .. the speaker ! You can use almost any commercially available loudspeaker, being it round, square, outdoor, indoor, brown, white, shiny, expensive or cheap … as long as it has 8 Ohm impedance (the vast majority is of that type) and it can accept min. 5W RMS driving power.

The installation is incredibly simpe – two loudspeaker wires are connected to the Exstreamer P5 (screw terminal block included), and the device is hooked up to the network a Cat5 cable (PoE providing switch, or use an in-line power supply). NO need to wire power and network separately to the device. Also, if space is a constraint, you can separate the speaker from the Exstreamer P5.
A lot of flexibility – and the good news is that the combo “Exstreamer P5 plus reasonsable ceiling speaker” costs less than the typical combined IP Speaker device !

This IP Speaker solution from Barix supports all the standard stuff others do – SIP, priority multicast stream etc, and in addition, our devices can also play MP3 or even AACplus streams, resulting in CD quality background music, if wanted.
And – last not least – the Barix Exstreamer P5 also has a local interface port for an affordable volume/source control. So you can even select a background music channel, set the volume – and of course, even if you turn down the volume and listen to background music, a priority page comes through at a predefined level.

Check this out now .. the Exstreamer P5 is the better IP Speaker ! Coming from a trusted brand in the IP Audio and VoIP space since 10 years .. Barix ! The same technology used in the Exstreamer P5 also runs evacuation systems in nuclear power plants and oil refineries, it is rock bottom stable, so there is no need to power cycle your ceiling mounted IP speakers or find that reboot button ever …

“The IP Speaker without the speaker”(TM), now from Barix.

Barix IP Audio devices are an excellent solution when it comes to special SIP interfacing applications. Being it an audio monitoring application, where a call should be placed if a microphone picks up sounds above a certain threshold, or a SIP door station – the standard SIP application, which can be loaded on all Annuncicom and Exstreamer devices, serves well.

But do you know that you can also use a Barix device as a SIP gateway to traditional, multizone paging systems ?

How do you then select a zone ?

The SIP firmware can control local relays on the device, if existing (Exstreamer 500, for example, offers 4 relays). These can be commanded in the SIP call by means of standard signalling (SIP Info and RFC2833). Many IP PBX’es also allow you to send specific commands when you initiate a call, this is the perfect time to select a zone automatically.

The Barix wiki contains a nice article describing the exact configuration necessary of an Asterisk instance to offer the luxury of direct zone selection by extension. If done this way, a user of the phone system can just dial one of a selection of extensions, and the Barix SIP Gateway (actually, an Exstreamer 500 or Annuncicom 1000 device) will select the specific zone(s) to page to automatically, based on the actual extension called.
Here is a link to the general overview of how this is done: SIP Paging

And here is the article detailing the bits and pieces on how to configure Asterisk to directly control the relays from SIP

Greetings !


Tai Chi in the IT Industry ?
icon4 09 29th, 2010| icon3Comments Off on Tai Chi in the IT Industry ?

NY Times recently published a nice article about the benefits of Tai Chi for everyone’s general constitution.

At Barix, we have now our first year anniversary of implementing a weekly Tai Chi lesson in the office. We have scheduled the lesson so that all employees who are interested can attend, and it is defined “business matter” so the time spent counts towards the working time.

I guess some of our customers may have noticed a further decrease of bugs and increase in quality of our products (IP Audio devices) .. a coincidence ? I guess not .. we have good reasons to continue the Tai Chi classes !

we are currently exhibiting at Innotrans in Berlin, Hall 4.1 – swing by to check out our offering, and the first one referring to this blog entry, approaching us at the booth, will be treated with a coffee 🙂

The favorite for our visitors is the brand-new Annuncicom 155, the first Barix Audio over IP product which is EN50155 compliant and thus fulfills the stringent requirements for on-board equipment in trains, busses, vessels. With IP65 rating and -40… +70’C operating range, it is also suitable for outdoor installations, bus stations etc. A great product for IP Audio call boxes too, especially when used with the SIP firmware …
Here’s a pic of our booth.

New STL IP software for Barix devices
icon4 09 20th, 2010| icon3Comments Off on New STL IP software for Barix devices


a new STL firmware is now available here. This software provides a host of new features, yet simplifies the use. It can be downloaded freely and installed on all our standard Barix IP Audio devices (Exstreamer, Instreamer and Annuncicom). Not all features are working on all hardware (for example, on an Exstreamer 100 you can only use the decoding functionalities, obviously). Best performance and full features are available if you use it on Exstreamer 1000 or Exstreamer 500 hardware.

Here’s a screenshot:

Major improvements and new features:
– New WEB User Interface with profiles (Locations) and single Apply
Full Duplex PCM (uncompressed), up to 48KHz sample rate
– Analog Audio Output Silence Detection
– Analog Audio Input/Output VU meter bars
Low Latency Frame Buffering
– Selectable high quality A/D converter (at 32 and 48 KHz)
– USB playback as fail-over or by relay trigger
Reflector Client included in same load (either/or selection)

The camouflaging algorithm which takes care of dropouts has been further improved as well, brief dropouts due to RTP useage (which is unidirectional) are practically unhearable. It’s probably a quite well hidden secret that our devices do this since many years …
