—— 5 types of industrial camera interfaces ——
There are various machine vision camera interfaces available, and such cameras are also referred to as industrial cameras. The following table summarizes the most common interface types, with Camera Link being a relatively unique case due to differences in compatibility, transmission performance, and other aspects compared to other widely used interfaces.

| Cable length (maximum) | 100m | 50m | 50m | 7m | 4.6m; 100m with fiber | 5m | 100m |
| Power + data on one cable | Only if PoE | Only if PoE | Only if PoE | Yes | Yes | Yes | PoCL |
| Frame-grabber mandatory | No | Yes | Yes | Yes | No | No | Yes |
| Cable costs | Low | Low | Low | Low | Low | Low | High |
| Camera costs | Low | Meduim | Meduim | High | Low | Very low | High |
| CPU usage | Meduim | Low (special framegrabber) | Low (special framegrabber) | Low | Low | Medium | Low |

—— Bandwidth of Industrial Camera: Key Analysis of Data Transmission Capability ——
The bandwidth of an industrial camera directly determines its data transmission capacity, serving as a core metric that impacts imaging efficiency. The bandwidth calculation formula is: Bandwidth (MB/s) = Resolution (Width × Height) × Pixel Depth (Byte) × Frame Rate (fps). For example, a 5-megapixel (2592×2048) camera with 12-bit (1.5 Byte) depth and 30fps requires approximately 239MB/s of theoretical bandwidth. If the interface (e.g., USB3.0, with a theoretical 400MB/s) lacks sufficient bandwidth, frame loss or latency may occur.
In practical applications, the appropriate interface must be selected based on the scenario: GigE (120MB/s) is suitable for medium-to-low-speed inspection, while Camera Link (850MB/s) or CoaXPress (1.25GB/s) is better suited for high-speed, high-resolution requirements. Optimization methods include reducing the frame rate, enabling ROI cropping, or upgrading the interface. Proper bandwidth planning is essential to ensure stable and efficient operation of industrial cameras.
—— Industrial Camera Interface Selection Guide ——
Choosing the right interface for your industrial camera is crucial for performance, reliability, and cost-efficiency. Here’s a simple breakdown to help you make the best decision:
1.High-Speed & High-Resolution Applications
(e.g., PCB defect inspection, semiconductor manufacturing)
●Recommended Interface: CoaXPress (1.25–6.25 Gbps) or Camera Link (850 MB/s–6.8 GB/s)
●Why? These support ultra-high-speed data transfer with low latency.
●Note: May require fiber optic extenders for long-distance transmission.
2.
Medium-Speed Multi-Camera Systems
(e.g., logistics sorting, automated production lines)
●Recommended Interface: GigE PoE (120 MB/s, 100m range with power)
●Why? Cost-effective, supports multiple cameras via a single network switch.
●Tip: Limit to ≤4 cameras per switch to avoid bandwidth congestion.
3.
Portable & Handheld Devices
(e.g., handheld quality inspection tools)
●Recommended Interface: USB3 Vision (400 MB/s, plug-and-play)
●Why? No extra drivers needed, ideal for short-range mobility.
●Note: Use shielded industrial-grade cables to reduce interference.
4.
Harsh Industrial Environments
(e.g., welding, stamping workshops)
●Recommended Interface: Fiber optic (10GigE SFP+) or ruggedized CoaXPress
●Why? Immune to electromagnetic interference (EMI) and long-distance signal loss.
