Surveillance-Slide2

Intel® is monitoring a variety of trends in the video surveillance market. One obvious trend is the conversion from analog to digital and from standard definition (SD) to high definition (HD). What may not be obvious is the recent adoption of wide dynamic range (WDR) CMOS image sensors. These types of sensors are quickly emerging in the surveillance and automotive markets because of their ability to reproduce images much like a person’s eye would see. Unlike standard sensors, WDR sensors are able to simultaneously capture and output images that contain details in the darkest of shadows along with the details in the brightest sunlight. Examples of this will be shown later in the presentation. What is also unique about WDR sensors is that they require advanced processing. No ASSP or DSP device has an appropriate control or data pipeline that can interface to and manage these sensors. For this, an FPGA (or ASIC) is required. Analytics is also a trend in the market. What was handled by multi-processor blade servers is now being moved into smaller, smarter cameras that must be powered over Ethernet connections. Thus, a powerful processing engine that emits little heat and consumes little power is required. The processing required for analytics in a camera may need to detect an array of triggers simultaneously (loitering, people counting, abandoned objects, etc.), and do all of this in real time at 1080p60 (1080 lines, 60 frames per second). To accomplish this, a low-power FPGA enabling multi-processing DSP techniques is needed. Finally, more administration flexibility is also desired as cameras become smarter. Camera operators want the ability to view and control the cameras from anywhere, even via mobile devices. Consumers also want to be able to quickly change and re-configure their surveillance networks on-the-fly, even wirelessly, without set-up hassles and re-working existing infrastructures. All of these trends also cause concerns for Intel's® customers. These market trends and pressures put extreme burdens on system designs, performance targets, and BOM costs. FPGAs can help resolve these challenges and have a positive impact.
