Keyence

It excels in broad industry coverage and direct sales system. It boasts prominent advantages in automotive manufacturing, lithium batteries, photovoltaic new energy, food & pharmaceutical packaging and precision electronics inspection. Keyence adopts a strategy of high gross margin plus robust services, locking in customers with total solutions and rarely engaging in price wars.

Teledyne (Teledyne DALSA / e2v)

It dominates the physical limits of high-end imaging. It is strong in high-end line scan, semiconductor advanced inspection (e.g., wafer inspection) and industrial thermal imaging (such as thermal inspection of power equipment and lithium battery temperature control). For applications requiring finer, faster or specialized imaging, Teledyne is hard to bypass.

Basler

It stands out for ecosystem and versatility. Its cameras are widely deployed in high-volume applications, supported by the industry-renowned Pylon SDK ecosystem, serving as a benchmark for general underlying hardware in industrial automation. Many engineers’ first industrial camera is a Basler model — ecosystem value often outlasts hardware specifications.

IDS

It features compact size, low power consumption and native Linux compatibility. It has advantages in Linux systems, embedded vision, edge devices and European industrial projects. Its core strengths are miniaturization, low power draw and native adaptation to Linux ecosystems. It is an inevitable choice for edge computing and embedded solutions.

II. Domestic Machine Vision: A Decade of Evolution from "Workable" to "Excellent"

If overseas brands hold the apex marked by high precision, high gross margin and mature ecosystems, domestic manufacturers have captured practical battlefields in recent years: cost performance, fast delivery and adaptation to local application scenarios. Based on industrial chain roles, they can be roughly divided into three categories: industrial camera hardware, vision algorithms & inspection equipment, light sources and core components. (In no particular order; only some well-known enterprises are listed.)

1. Industrial Camera Hardware

HIKROBOT

One of China’s largest-volume suppliers of industrial cameras. Its product portfolio covers area-scan, line-scan, 3D and smart cameras plus vision platforms. Leveraging Hikvision’s supply chain and channel resources, it gains strong advantages in pricing and lead time for standard products. In recent years, it has expanded into mid-to-high-end scenarios including AI barcode reading and 3D guidance.

Huaray

Machine vision brand under Dahua Technology. Its product lineup includes industrial cameras, code readers, 3D cameras and vision algorithm platforms. Together with HIKROBOT, it forms the "two giants" of domestic industrial cameras, with deep implementation experience in lithium batteries, 3C electronics and logistics.

Daheng Imaging

One of China’s earliest industrial camera manufacturers with solid technical heritage. It enjoys a solid reputation in research, medical and astronomical imaging where strict image quality requirements apply. Unlike internet-style operations, it operates more like an engineer-founded enterprise.

LUSTER

Started as a distributor for overseas brands such as JAI and Teledyne, then developed self-owned industrial cameras and vision systems. It offers mature solutions for printing & packaging inspection and 3C electronics inspection, representing the typical growth path "from channel sales to in-house product development".

OPT

Founded on machine vision light sources, now its product range covers light sources, lenses, cameras, vision controllers and complete turnkey solutions. It delivers strong solution capabilities for 3C electronics and lithium battery industries, and is one of the few domestic vendors capable of delivering integrated opto-mechatronic-computing packages.

Acoo

A key pioneer of high-end domestic line-scan cameras. Its industrial line-scan and high-resolution imaging products compete with overseas brands such as Teledyne, targeting high-demanding scenarios including semiconductors, 3C electronics, PCBs and lithium batteries. It represents domestic substitution efforts climbing toward the high-end market apex.

DeepVision / Zhongke Shiyu (3D & Structured Light)

DeepVision focuses on 3D vision and structured light measurement, achieving rapid growth in 3C precision measurement and lithium battery inspection. Zhongke Shiyu specializes in integrated 3D camera and AI vision solutions. Domestic vendors generally iterate faster in the 3D field compared with traditional 2D vision.

2. Vision Algorithms & Inspection Equipment

Aqiu Technology (AI Defect Inspection)

Focuses on industrial AI defect inspection, with wide deployments in appearance inspection for 3C electronics, lithium batteries and automotive parts. It features small-sample learning and rapid deployment.

JCETest · KINGSEM (Semiconductor Inspection)

JCETest is the domestic leader in display panel inspection and extends into semiconductor metrology and inspection. KINGSEM specializes in front-end semiconductor metrology & inspection equipment, a critical player for domestic semiconductor inspection hardware. Both target the high-end market regarded as the hardest nut to crack for overseas brands.

Tianzhun Technology · JUTZE Intelligence (Precision Measurement / AOI)

Tianzhun Technology has accumulated deep expertise in precision measurement and 3C inspection equipment. JUTZE Intelligence is a representative AOI vision inspection equipment manufacturer, competing head-to-head with foreign AOI brands in SMT and semiconductor packaging applications.

3. Core Components & Light Sources

Changphoton · Dongzheng Optics · MTOptics (Industrial Lenses)

Domestic industrial lens makers have made remarkable progress. For medium-low magnification and standard resolution scenarios, domestic lenses can replace imported alternatives, while they are still catching up in high-end specifications such as telecentric lenses and high-power microscope objectives. Lenses are a typical category that look simple yet are extremely difficult to manufacture.

LeShine Light · Cosara Vision (Machine Vision Light Sources)

Machine vision light sources represent the most fully realized segment of domestic substitution. From ring lights and bar lights to coaxial lights and combined light assemblies, domestic suppliers hold clear advantages in cost and custom development speed, having largely replaced imported products.

III. What Is the Gap Between Domestic and Overseas Brands?

The comparison below clearly illustrates the differences:

表格

Domestic substitution is not a question of "whether it works", but "at which level it works". For routine inspection, logistics barcode reading and 3C assembly, domestic solutions have become the default option. For semiconductor front-end processes, high-end line scan and specialized imaging, overseas brands remain hard to replace. What deserves close attention is the upward path of domestic manufacturers moving upward from mid-tier markets toward the industry apex.

IV. Key Considerations for Product Selection

Back to engineering practice, answer three questions before selecting an industrial camera:

1. What are the precision and speed requirements? For standard 2D area-scan inspection, domestic solutions are sufficiently mature. If your application involves sub-micron measurement, ultra-high-speed line scan or special spectral imaging, start by evaluating high-end overseas options.
2. Is your software stack already locked in? If your team heavily uses Pylon or VisionPro, hardware price difference is not the only switching cost; you also need to account for development habit migration and algorithm porting.
3. Do you require fast on-site iteration? When requirements change frequently during production line commissioning, domestic manufacturers with direct on-site support often deliver decisive response speed.

The charm of the industrial vision industry lies in its unique market pattern: it is neither a winner-takes-all market like consumer electronics, nor an industry purely driven by cost as traditional manufacturing. Algorithms, hardware, services and ecosystem — progress cannot be sustained without all four pillars. This is exactly what domestic vendors are building step by step.
