Developments in the surveillance industry are fueling the island’s R&D on related ICs, camera modules and DVR cards.
HD video enhancement and low light recording are the two main trends for CCTV and IP cameras. Taiwan makers are therefore rolling out components supporting better resolution. Grain Media Inc., for instance, has released SoCs with 5MP and 1080p. It is developing technologies for IP cameras that will enable high integration and quality, and less power consumption at more attractive prices. R&D initiatives include HD encoders with a lower bit rate and elevated image resolution to meet requirements on data fidelity, self-protection and event awareness. The supplier is also eyeing components for next-generation NVRs and HD CCTVs. These involve multiformat encoders and decoders, full-HD processing from capture to display with graphic engine, and SoCs with advanced processing such as 55nm technology.

Grain Media said USB TV cameras will be popular in coming years. Its portfolio now includes models that support H.264 encoding and up to 1080p resolution at 30fps.
Other enterprises offer components with high-resolution recording under low light of 0.01 lux. Mainstream units currently work at less than 0.1 lux, and have 1080p resolution at 30fps and up to 1,000 TVL. For sensors, most Taiwan-made SoCs support Sony, Aptina, Omnivision, Himax Imaging, Sharp and Panasonic units. An image signal processor and wide dynamic range function are commonly integrated into such solutions to stabilize image.
The H.264 has become the mainstream recording format, especially for IP models, as it occupies only one-third of the storage size of MPEG-4. The HD camera segment based on this standard is expected to rise gradually, driven by demand from IP, TV and car cameras, and video- and smartphone connectivity.
For DVR cards, suppliers have launched models for the latest Intel Core processors. Recent releases support the Sandy Bridge platform. They enable software compression for video recording based on H.264, and 8-channel 1080p real-time recording and display. Tribrid surveillance capability is boosted, which involves support for HD-SDI, IP and CCTV transmission formats.
There are currently 10 to 20 manufacturers of DVR cards in Taiwan. About the same number provides ICs.
