Texas Instruments and Micron’s Aptina Imaging deliver HD quality for IP surveillance networks at analog video camera prices
New security camera reference design provides flexibility for an easy upgrade path to IP video
HOUSTON and SAN JOSE .- As security camera system designers move from aging CCTV to high-quality Internet Protocol (IP) networks, they are challenged with keeping overall system costs down, increasing image quality and reducing camera design complexity and implementation time. Recognizing these challenges, today Texas Instruments Incorporated, (NYSE: TXN) and Aptina Imaging, a division of Micron Technology Inc., announced that they are offering the DM355IPNC-MT5 high-definition (HD) IP network camera reference design based on TI’s DaVinciTMÂ TMS320DM355 digital media processor and Aptina’s 5-megapixel HD security image sensor. With an electronic bill of materials (eBOM) costs of less than $40, video surveillance providers can now add these cameras to their existing systems - at the cost of a traditional analog video camera â€“ and gain the flexibility to upgrade to an IP-based, HD network camera when ready.

"The rapidly growing market for security and surveillance cameras is fueling the need for increasing levels of image quality and functionality at affordable prices" said Curtis Stith, Director of New Markets for Aptina. "Through our joint development work with TI on this new reference design, we are making it much easier for security system designers to make the shift to high quality IP network video"
Scalability, increased field of view and low power
Unlike traditional CCTV cameras, the DM355IPNC-MT5 allows for simple scalability while providing remote viewing and storage capabilities in a distributed network. Complexity and cost of the network are reduced by utilizing the TI/Aptina reference design, producing a field of view of 1280 x 720 pixels, whereas traditional surveillance systems typically use two D1 cameras each seeing 480 x 720 pixels to capture the same scene. Additionally, by leveraging Aptina’s 5-megapixel image sensor, image quality is greatly improved with the sensor delivering exceptionally low noise levels and low-light sensitivity.
The IP camera reference design also supports analog output for existing CCTV customers who are not yet ready to migrate to IP allowing them use the camera system to future-proof their investment. Functioning at 400mW during HD MPEG-4 encode, the TI/Aptina camera can operate at less than 3W, reducing the power requirements of even complex networks.
Optimized reference design reduces development time to four months
From device drivers and application software to hardware and image pipe tuning, a video surveillance camera system can often take more than 150 man months to develop. The DM355IPNC-MT5 reference design reduces system development to less than four months by including complete and optimized schematics, gerber files, as well as free Linux application source code. Included in the source code, for example, is functionality for integrated auto white balance/auto exposure, simple motion detection, dual stream HD MPEG4 and MJPEG video codecs and DaVinci IP network camera software frameworks to quickly bring this camera into production. The reference design further saves time and drives performance by taking advantage of TI’s wide portfolio of analog, power management and logic technology including the TLV320AIC26 audio codec and the TPS23750 Power over Ethernet controller.
"The combination of TI’s DaVinci DM355 digital media technology with Aptina’s leading image sensor makes for a powerful but highly cost effective solution" said Danny Petkevich, video surveillance and imaging business manager, TI. "Working closely with Aptina, we’ve removed the traditional barriersâ€”like cost, complexity and design skill setsâ€”to implementing IP-based HD video surveillance systems"
Pricing and Availability
Order entry is open for the TI/Aptina HD IP network camera reference design at www.ti.com/ipnetcampr. The $795 royalty free reference design includes the camera, tripod, cables, and power adaptor as well a quick start guide and production agreement. The camera system is expected to begin shipping in the second quarter 2008.
For production quantities, TI’s DM355 processor is available today at just $10 and consists of an integrated video processing subsystem, an MPEG-4-JPEG co-processor (MJCP), a 270 MHz ARM926EJ-S core and peripherals. The DM355 also includes an integrated digital to analog converter (DAC) which can be used along with the OPA361 video amplifier to drive composite PAL or NTSC output. The MJCP provides HD MPEG-4 SP encode or decode at 720p and 30 frames per second and JPEG encode or decode at 75 MegaPixels per second. Additional information can be found on TI’s website at www.ti.com/dm355.
Both TI and Aptina Imaging will have demonstrations featuring the IP net camera reference design at ISC West, April 2-4, 2008; TI will be in the Object Video booth #15097 or visit Aptina Imaging at booth #39008.
