At this year’s Global Electronic Monitoring Application Forum (COMPOSEC), key components like HD, FPGA, WDR, and SDI have emerged as top search terms. The **HD transmission scheme** is gaining momentum, with high-resolution imaging becoming a central focus in the global market. This year saw participation from industry leaders such as ITE, Valence, and Toshiba, further solidifying the trend. The development of technologies like ccHDtv, HDBaseT, and HDCVI has reached new levels of maturity. Notably, start-ups like Startdot Technologies in the U.S. and altasec from Taiwan have showcased complete products based on ccHDtv technology.
ccHDtv enables the transmission of 1080P@30 or 1080P@60 video and audio over standard coaxial cables such as 3C2V/RG59, reaching up to 500 meters without a repeater. Similarly, HDCVI can also support distances of at least 500 meters. These solutions not only extend the use of existing cabling infrastructure but also overcome the limitations of traditional SDI, offering more reliable and efficient high-resolution transmission. As a result, non-IP-based high-resolution transmission systems that outperform HD-SDI are gaining traction and deserve close attention.
The **FPGA momentum is growing**, with IC suppliers showing more proactive engagement this year. The emphasis on image processing capabilities has become even more pronounced, especially for SDI device manufacturers. According to Jiang Yungui, Altera’s Industrial Market Development Manager for Asia-Pacific, SoCs using FPGAs offer three major advantages. First, they combine the convenience of ASICs with the flexibility of DSPs, allowing for easy adjustments without requiring complex reprogramming. For example, color temperature settings can be modified directly, unlike in traditional DSP systems where low-level configurations are necessary.
Second, FPGAs support multitasking, enabling hardware analysis and secondary development to provide additional value-added functions, such as ISP or IVS. Third, since FPGAs can process raw images without converting them into digital signals, they reduce conversion loss and BOM costs while improving analysis performance. This makes them particularly appealing for SDI equipment manufacturers aiming for real-time, distortion-free image processing.
Despite being about 10% more expensive than DSPs, FPGAs can handle 3G-SDI signals, posing a potential threat to companies like TI and Semtec that rely on ASIC and DSPSoC solutions.
**WDR has become a must-have feature** for chip manufacturers. This year, IP surveillance products are shifting focus from high-resolution pixels to performance in low-light and high-dynamic-range conditions. Leading chipmakers like Texas Instruments introduced the DM369, which emphasizes advanced low-light technology and noise suppression. Sony launched the SoCXarina, combining ISPs, video encoders, and ARM CPUs, offering ultra-wide dynamic range and 1080p@60 resolution. WDR is no longer just an image sensor feature; it's now being integrated into back-end SoCs, known as TrueWDR, making it a competitive battleground among sensor, ISP/DSP, and SoC manufacturers.
The **SDI program is maturing**, with optimized Tx and Rx solutions from companies like Semtech, TI, and Intersil. South Korean manufacturer Nextchip recently partnered with Semtech to launch the ISPNVP2410, supporting both HD-SDI and 3G-SDI. Magnision, a Chinese company, also showcased SDI chips for cameras and DVRs, hinting at potential price competition in the SDI chip market.
**Work platforms are becoming more mobile**, with Windows-based security products seeing slight growth. This is due to increased support for mobile devices, with Microsoft’s Windows CE offering lightweight, embedded OS features ideal for real-time monitoring and cloud integration. Windows Azure is also expected to play a significant role in future cloud-based applications, bridging the gap between IT and security industries.
**Hard drives are focusing on capacity and reliability**, with AV hard drives now commonly available in 3TB and enterprise-grade models reaching 4TB. Professionals are increasingly aware of the importance of fault tolerance and capacity management, with features like bad track self-checks becoming essential.
Finally, **the monitoring sector is entering the SSD market**, with manufacturers like Apacer and A-DATA showcasing SSDs and wide-temperature DDR3 SO-DIMMs. As cloud computing becomes more prevalent, the need for fast, stable storage solutions like DOM modules is rising, opening a new opportunity for flash memory vendors. The lines between security monitoring and IT are blurring, signaling a promising future for the industry.
