Why NovoSIP video doorphone?

novosip-sIt opens the door to you, from your workplace or on the go from your tablet or Smartphone running Android.

Calls are sent to the user as a call from Skype but in fact the technology is Open Source. Suddenly you have a video intercom that works on all devices you want to connect it (Android only for now).

The SIP protocol is the standard protocol of the professional IP telephony in the world.  SIP means “Session Initiation Protocol”. SIP is a request-response protocol, dealing with requests from clients and responses from servers.

The addition of video IP using the H.264 video coding is another standard that explain why our door station is able to connect with most of SIP client applications running on several OS like iOS, Android, Linux and Windows.

How it works?

The NovoSip Video door panel works with Raspberry Pi, the tiny Linux card at 30 Euros which is actually a small computer. NovoSIP has an extension small electronic card connected to Raspberry Pi which forwards the call to a visitor on the Android Smartphone owner who can then view the visitor, converse with him and open the door.

How is the door panel powered?

PoE SwitchIt is powered by PoE 100%. Just spend a category 5 or higher cable from the PoE switch to the platinum NovoSIP. Even the electric lock is supplied with PoE! Need complicated installation: you connect the PoE switch on the box or the Internet router, then connect the Category 5 Ethernet cable connecting the RJ-45 connectors on each end. There are currently more than connect the two son of the electric lock directly on the terminal block of the plate!

Why SIP?

asteriskBecause a SIP client software is installed in the Raspberry Pi is set in relation to the SIP client software on the tablet or Android Smartphone when a visitor presses the call button. The linkage between the two is made by the Open Source Asterisk SIP server that serves as PBX.

The advantage of this technology is that it is Open Source and thus we can make devices together from different sources operate, use smartphones or tablets or even PC to communicate. Just install a SIP client. For the door opening on selected parameters in the system, eg dialing tone dialing (DTMF).
