New Production-Ready HD 5MP Camera Reference Design

September 20, 2011

Bedford, MA, ChipWrights Inc. - part of AD Group - announces new production-ready, high definition 360 Degree IP camera reference design. Key features include:

  • Aptina® MT9P031 5MP sensor
  • 180 degree fish-eye lens
  • Power over Ethernet (PoE)
  • Built-in microphone
  • MicroSD card
  • Audio input/output jack
  • Composite video output
  • Digital input/output lines
  • Auxiliary 12V power input (for applications that don’t use PoE)

Our 5MP camera is a “complete, ready-to-manufacture 360-degree IP camera system that provides the flexibility and extra processing power to add unique features, such as image enhancement; unique sensor technology; and video analytics, such as face detection or virtual tripwires,” says Cary Robins, President of ChipWrights.

The reference design incorporates two ChipWrights’ CW5631 System-on-Chips (SoCs).

  • One SoC is the stand-alone image sensor pipeline (includes source code and is easily extended with customer features)
  • The second SoC runs the camera system; it controls the Ethernet, SD card, audio and video inputs/outputs, and performs video compression to MJPEG, MPEG4 or H.264

Two SoCs mean that "camera functionality can easily be moved between the processors depending on load and the application," says Robins. "For example, our baseline camera uses an Aptina 5MP sensor; dual ChipWrights CW5631 devices do the image sensor pipeline, fisheye lens image dewarping, image compression and transmission."

“With a simple redesign of the sensor board, an SoC sensor can be used and the camera can be modified to perform full 1080p30 dewarping and compression on the two chips,” adds Robins.

The camera reference design software includes a web server—the camera can be set up and controlled by a standard web browser—and adds video streaming, which enables the output to be viewed on a PC over the network, as well as from the dedicated composite output.

  • The software supports DVR functionality to the on-board MicroSD card.

  • The 360-degree camera reference design offers a 180-degree field of view, which can be presented as a single view, dual (panoramic) views, or quad views.

  • Digital Pan-Tilt-Zoom (PTZ) can be controlled from the browser interface, as can compression, recording features and IP configuration.

The camera provides high definition video and is much smaller in size than previous reference designs. In addition, ChipWrights offers the system level camera software as free source code and the signal processing features in a binary library. The unique added functions available in the binary include: dewarping software, denoising and dynamic range enhancement. All of the DSP libraries are available for purchase as source code.
