At this year's Global Electronic Monitoring Application Forum (COMPOSEC), key components such as HD, FPGA, WDR, and SDI have become major search terms among industry professionals. The **HD transmission scheme** is experiencing a surge in popularity, with high-resolution imaging becoming a central focus of global trends. This year saw the participation of companies like ITE, Valence, and Toshiba, further fueling the growth of this sector. The trend continues to thrive, with technologies like ccHDtv, HDBaseT, and HDCVI gaining momentum.
In particular, **ccHDtv** has made significant progress, with U.S. startup Startdot Technologies and Taiwanese company altasec showcasing finished products. This technology enables the transmission of 1080P@30 or 1080P@60 video and audio over standard coaxial cables, reaching up to 500 meters without a repeater. Similarly, HDCVI also supports long-distance transmission, breaking the limitations of traditional SDI systems. By utilizing existing cabling infrastructure, these solutions not only extend cable use but also overcome distance constraints, making them increasingly attractive in the market.
The **FPGA momentum** is also growing rapidly. Compared to last year, FPGA suppliers are showing more proactive engagement. This year’s focus on image processing capabilities has been even more emphasized, especially for SDI device manufacturers. According to Jiang Yungui, Altera’s Industrial Market Development Manager for Asia-Pacific, SoCs using FPGAs offer three main advantages: flexibility, multitasking, and direct raw image processing. Unlike DSPs, which require complex reconfiguration, FPGAs allow for quick adjustments, such as changing color temperature, directly on the design.
Additionally, FPGAs can handle multiple tasks simultaneously, enabling hardware analysis and secondary development to add value for customers. For example, ISPs can be used for IVS (Intelligent Video Surveillance) applications. As demand for high-resolution, real-time, and front-end analysis increases, the advantages of FPGAs will become even more evident. Despite being about 10% more expensive than DSPs, FPGAs can handle 3G-SDI signals, posing a potential threat to traditional ASIC and DSPSoC suppliers like TI and Semtec.
Another key area is **WDR (Wide Dynamic Range)**, which has become a must-have for chip manufacturers. This year, IP surveillance products are no longer focusing solely on high pixel counts but rather on performance in low-light and high-contrast environments. Texas Instruments introduced the DM369, featuring advanced low-light technology and noise suppression. Sony released a SoC with ultra-wide dynamic range, offering over 120 dB noise ratio and 1080p@60 resolution. With WDR now being integrated into back-end SoCs, it's becoming a competitive battleground, with Sony emerging as a strong player.
The **SDI program** is also maturing. Since its launch three years ago, HD-SDI Tx and Rx solutions have been optimized by companies like Semtech, TI, and Intersil. This year, South Korean manufacturer Nextchip partnered with Semtech to introduce the ISPNVP2410, supporting both HD-SDI and 3G-SDI. Meanwhile, Chinese firm Magnision showcased SDI chips for cameras and DVRs, hinting at a potential price war in the SDI chip market. Despite the competition, component manufacturers remain optimistic about the future of SDI products.
In terms of **work platforms**, there is a growing shift toward mobile solutions. While Linux remains popular for its stability and cost-effectiveness, Windows-based security products have seen a slight increase due to better support for mobile devices. Microsoft’s Windows CE platform offers embedded features, real-time performance, and cloud integration, making it ideal for monitoring systems. With the rise of cloud computing, the need for lightweight, efficient front-end equipment is becoming more critical.
Regarding **hard disk storage**, capacity and reliability continue to be top priorities. Surveillance-grade AV hard drives now commonly feature 3.5-inch form factors, SATA 3.0 interfaces, and 2TB capacities, with 3TB and 4TB enterprise models already available. Professionals emphasize the importance of fault tolerance, self-check mechanisms, and shock resistance, particularly for monitoring applications that require heavy write operations.
Finally, the **SSD market** is expanding, with flash memory vendors like Apacer and A-DATA introducing SSDs and DDR3 SO-DIMMs. As cloud computing becomes more prevalent, the demand for fast, reliable local storage and redundant backup solutions is increasing. This convergence between security monitoring and IT is creating new opportunities for flash memory providers, blurring the lines between industries.
