1.2 Special Specification Lenses
In special specification products such as long-focal-length fog-penetrating lenses and laser infrared integrated lenses, certain domestic manufacturers have achieved technological breakthroughs, with products applied in forest fire prevention, maritime border defense, and other scenarios. However, in the high-end optical design segment for ultra-low-light star-level lenses, there remains a certain gap compared to international advanced levels.
1.3 Overall Assessment
The localization level for standard specification lenses in the lens segment is relatively high, capable of meeting most project requirements in the Southeast Asian market; for special scenario high-end lenses, it is recommended to confirm supplier technical capabilities based on specific applications.
2. Image Sensor Modules: Medium Localization Level
Image sensors are key chips determining core camera image quality. Currently, industry mainstream solutions include modular designs combining CMOS sensors with signal processing chips.
2.1 Sensor Chip Supply
The global security image sensor market has multiple major suppliers, including several international brands mentioned in industry public information. In key indicators such as resolution, low-light performance, and wide dynamic range, certain international manufacturers still hold dominant positions in the high-end market.
2.2 Module Packaging and Calibration
Domestic capabilities in lens assembly, sensor testing, and ISP calibration for module packaging have matured. Some domestic solution providers can offer module solutions based on different brand sensors, adapting to product lines with varying positioning from entry-level to high-end.
2.3 Overall Assessment
The image sensor chip segment has certain external dependencies, but domestic capabilities in module packaging and solution integration are relatively mature. Integrators need to pay attention to whether sensor brands and specifications meet project image quality requirements during component selection.
3. NVR Equipment: High Localization Level
Network Video Recorder (NVR) serves as the storage and management core of security systems, encompassing hardware platforms, software systems, and decoding capabilities.
3.1 Hardware Platform
NVR hardware cores include processor chips, motherboard design, and chassis structure. Domestic applications in embedded processors and ARM architecture solutions have matured, with high hardware localization levels.
3.2 Software Systems and Functions
Domestic NVR manufacturers have invested significant R&D resources in video management, intelligent analytics, and local human-machine interaction development. Products generally support multi-channel HD access, motion detection, perimeter protection, and other standard intelligent functions.
3.3 Overall Assessment
NVR equipment has high localization levels from hardware to software, with domestic products holding strong price competitiveness and functional adaptation capabilities in the Southeast Asian market. Channel partners can focus on equipment stability and after-sales response capabilities during component selection.
4. Storage Media: Medium-to-Low Localization Level
Storage is a critical guarantee segment of video surveillance systems, involving hard drives, SSDs, and storage arrays.
4.1 Mechanical Hard Drives
The surveillance-grade mechanical hard drive market has long been dominated by international brands. Domestic manufacturers have technological gaps in core components such as platters, magnetic heads, and controller chips for enterprise/surveillance-grade drives. Currently, some domestic manufacturers participate in the market through complete machine or system integration approaches.
4.2 Solid-State Storage
In the SSD sector, domestic manufacturers such as Yangtze Memory Technologies have made progress in NAND Flash memory particles, but controller chips, firmware algorithms, and other segments still require continuous breakthroughs. Consumer-grade SSD localization is gradually improving, while enterprise-grade surveillance SSDs still require observation.
4.3 Overall Assessment
Storage media represents a segment with relatively lower localization in the security supply chain. It is recommended that channel partners conduct sufficient evaluation of storage equipment supplier qualifications and product reliability for large-scale projects.
5. Engineering Cables: High Localization Level
Video transmission and power supply cables are important components of security system engineering.
5.1 Network Cables and Fiber Optic Cables
Products such as Cat5e/Cat6 network cables, Cat5e outdoor waterproof cables, and fiber optic patch cords have complete domestic production capabilities, meeting project requirements for transmission distances ranging from hundreds of meters to several kilometers.
5.2 Power Cables and Composite Cables
Products such as RVV power cables, RVVP shielded cables, and composite wiring cables have high localization levels, with domestic manufacturers capable of providing customized solutions with different specifications and sheath materials.
5.3 Overall Assessment
The engineering cable segment has sufficient supply and transparent pricing, with domestic products capable of meeting various security engineering deployment requirements in the Southeast Asian market.
