HD IP Camera reference design

HD IP Camera reference design
With a surveillance camera system transition from traditional CCTV technology to high-quality IP network surveillance camera system designers are faced with a series of technical challenges to reduce overall system cost and improve image quality, reduce camera design complexity and reduces installation time. Texas Instruments (TI) Aptina Imaging and Micron Technology, Inc. 's efforts to help customers solve the above problem, has announced jointly launched based on TI's DaVinci TMS320DM355 digital media processor and Aptina's 5 megapixels HD security image sensor DM355IPNC-MT5 HD IP Camera reference design. The solution electronic bill of materials cost (eBOM) less than $ 40, helps video surveillance suppliers add to the cost of traditional analog video camera digital video camera to the existing system, and at the appropriate time the flexibility to upgrade to HD IP Camera.
Scalability, greater field of vision, and low power consumption
Unlike traditional CCTV cameras, DM355IPNC-MT5 in the distribution network to support far observation and storage capabilities, but also the ability to facilitate scalability. With TI and Aptina's reference design, the complexity and cost of the network can be reduced, the field of view of 1280 x 720 pixels, traditional monitoring system is usually two field of view of 480 x 720 pixels the D1 camera in order to capture the same scene . With Aptina's 5-megapixel image sensor, image quality has not only been significantly improved, and the interference signal of the sensor is very low, less susceptible to the dim light and affect the image quality.
IP camera reference design also supports has yet to do a good job preparing for upgrading CCTV IP customers analog output, allowing them to use the camera system to meet the technical requirements of the future, to ensure that the value of investments. TI and Aptina camera power to 400mW in HD MPEG-4 encoding process, the overall operation of the power consumption of less than 3W, reaching the advanced network for low power requirements.
4 people workload optimized reference design development time shortened to a single month
From the device driver and application software to hardware and image pipeline commissioning, video surveillance camera systems development work usually requires a single month 150 people to complete the workload. DM355IPNC-MT5 reference design contains the complete optimization diagram, Gerber files, and free Linux application source code, system development time can be shortened to less than 4 monthly workload. Source code, for example, also includes integrated automatic white balance / auto exposure, simple motion detection, the Shuangliu HD MPEG4 and MJPEG video codecs and DaVinci IP network camera software framework, help to make the camera quickly put into production. The reference design also includes TI extensive range of analog, power management and logic technology, such as TLV320AIC26 audio codec TPS23750 Power over Ethernet controller, which further saves time and improves performance.
