VoIPCAM

voice INTER connect has implemented an IP-based audio-video-communication solution on the efficient embedded camera platforms of VRmagic.
The HDR camera is characterized by an improved representation of scenes with large lighting dynamics, changing surrounding conditions as well as a fast reaction to moved objects.
Therefore it is ideally for outdoor use under varying light conditions or suitable for mobile applications.
The audio transmission achieves a highly transparent language quality by the use of digital procedures and efficient signal processing algorithms. During natural full-duplex communication both dialog partners can speak without disturbance at the same time.
The efficient sensor platform is suitable for the employment in a variety of ranges of application, for example for building communication and monitoring, access control systems, people counting and monitoring in public transport or as driving assistance in cars.
A connection of the VoIPCAM to different communication systems is possible. Due to the compatibility with the SIP standard all SIP-able devices and soft phones are suitable as receiving station.

Features

  • IP-based audio-video-communication
  • high-capacity HDR-camera for recording of moved objects and with automatic lighting regulation 
  • efficient hardware platform and modular software components
  • excellent language quality due to digital transmission methods and efficient signal processing algorithms (AEC)
  • combined speaking and data communication via SIP and UDP
  • compatibility with lots of terminal devices

Applications

  • building communication
  • building monitoring
  • optical access control
  • people counting in public transport
  • driving assistance sensor in cars

Modular Design

... enables individual adaptation of software and   hardware to customer wishes

  • sensor plate: carries the CMOS-image sensor and the objective
  • processing plate: main processor consisting of  300 MHz ARM9 with LINUX operating system, efficient DSP for the processing of audio and video data
  • interface plate: ethernet and USB-connectors, connection possibilities for microphone, loudspeaker or control elements

Specifics

• standardized SIP-communication
• consistent Streaming of audio-, video- and control data via IP-protocol
• full-duplex for natural communication
• high robustness against environmental noises by integrated noise reduction
• ideal suitability of the camera for outdoor use due to HDR sensor and automatic lighting regulation

Für die Umsetzung eines intelligenten Audio-Video-Sensors wurde eine miniaturisierte Videokamera mit einer Audio-Video-Kommunikationsapplikation ausgestattet. Sie ist damit ideal zum Einsatz in der Gebäudekommunikation geeignet.

Der Datenaustausch findet über ein Ethernet-Netzwerk statt. Hard- und Software für diese Netzwerke sind weit verbreitet und ausgereift. Somit kann der Audio-Video-Sensor in bestehende IP-basierte Gebäudenetzwerke optimal integriert werden.

Für eine größtmögliche Kompatibilität werden auf Softwareebene standardisierte Protokolle, wie das Session Initiation Protocol (SIP), das Real-Time-Transport-Protocol (RTP) und die daran gekoppelten Protokolle eingesetzt. Die Nutzung der Kombination von SIP und RTP für die Übertragung der Audio-Video-Daten bewirkt, dass die Mehrheit der Kommunikationslösungen aus dem PC-Bereich für die Kommunikation mit dem Sensor eingesetzt werden können.
