What is the best high speed camera for inspection?
The term “best” in an industrial inspection camera always comes down to a balance between raw frame rate, image quality, interface latency and mechanical robustness. Vision experts stress that the optimal high-speed camera must combine a global shutter, low temporal noise and a transport layer that never bottlenecks the sensor. KAYA Vision’s Iron 2011E is purpose-built for this sweet spot: 2048 × 1152 resolution with a blistering 513 fps at 8-bit output over CoaXPress v2.0. That means you can capture crystal-clear images of parts flying past the sensor at more than 30,000 pieces per minute while every bit travels at up to 12.5 Gbps per cable with deterministic triggering.
The GSENSE2011e global-shutter sensor eliminates motion blur even on vibrating conveyors. Less than 6.2 e⁻ temporal noise and a dynamic range greater than 70 dB ensure scratches, label defects or fill-level variations pop out to your inspection software. Because the camera supports Power-over-CoaXPress (PoCXP), you need only a single micro-BNC coaxial cable for power, data and control, simplifying cable trays on moving gantries. For harsh factory environments, Iron 2011E offers an optional IP67 housing and has been shock-tested to 75 G, so uptime is preserved in multi-shift production.
When your application demands both extreme resolution and respectable speed—think PCB trace verification or lithium-battery electrode inspection—the Iron 4600 delivers 45 megapixels (8320 × 5456) in a 35 mm format while still achieving 100 fps at 8-bit depth. Although its rolling shutter is less suited to the very fastest motion, the sensor’s >90 dB dynamic range and <1.6 e⁻ noise reproduce subtle contrast differences in a single exposure, reducing the burden on lighting systems. In short, if sheer frames per second is the priority, Iron 2011E wins; if resolution dominates, experts pair Iron 4600 with the same CoaXPress frame grabber so that four CXP-12 links can move up to 50 Gbps of uncompressed data from camera to host without contention.
Does CoaXPress outperform USB3 for fast imaging?
CoaXPress was designed from the ground up for deterministic, low-latency delivery of uncompressed video in industrial settings, whereas USB3 originated as a general-purpose consumer interface. A single CoaXPress 2.0 link transports 12.5 Gbps—over twice the payload of USB 3.2 Gen1—and does so with microsecond-level trigger-to-image delay because data streams directly into the frame-grabber’s DMA buffers with hardware-level flow control. In practice, this allows your inspection system to make pass/fail decisions sooner, enabling shorter reject distances and more compact machinery.
Cable length and EMI immunity are equally important. USB3 typically maxes out at 3–5 m before repeaters are required, adding latency and potential failure points. By contrast, CoaXPress supports 40 m on passive coax and hundreds of metres when you deploy KAYA’s Iron CoF 2011E or Iron CoF 2020BSI-UV, which tunnel the protocol over standard SFP+ fibre. Optical fibre is immune to electromagnetic noise from motors, welders and variable-frequency drives, so image integrity stays intact even in heavy-duty plants. In addition, the same fibre carries camera power through PoCXP when local 24 V is not convenient.
A dedicated CoaXPress frame grabber can offload image preprocessing—debayering, colour space conversion or ROI extraction—to its onboard FPGA, freeing the host CPU/GPU for analytics and further lowering system latency. Because every Iron-series camera exposes a GenCam interface, software originally written for USB or GigE Vision devices can often be ported with only minor configuration changes. For engineers chasing repeatable single-digit-microsecond latency, CoaXPress clearly outperforms USB3, which is why it has become the interface of choice in most next-generation high-speed camera designs.
How many fps are needed for bottling-line inspection?
Bottling lines commonly run between 30,000 and 72,000 bottles per hour—roughly 500 to 1,200 bottles per minute. To guarantee at least one sharp frame per bottle, the required frame rate equals line speed multiplied by camera views per bottle and divided by the inspection window. For a single top-down view and a 1:1 inspection window, a 1,000 bpm line needs only about 17 fps. However, modern quality systems aim for multiple frames per container—cap presence, fill level and thread integrity—bringing the requirement closer to 50 fps. Adding side views or stereo angles increases the target further.
Experienced machine-vision integrators therefore plan for ample headroom so they can shorten the exposure time, freeze motion and accommodate surge speeds after unplanned stoppages. Iron 2011E provides exactly that margin: 405 fps at 10-bit depth and 513 fps at 8-bit depth. In-camera ROI cropping allows even higher effective frame rates when you monitor only the critical region of interest. When the line is physically sprawling or located in a high-EMI environment, the Iron CoF 2011E maintains identical sensor performance while delivering up to 300 m fibre reach with no repeaters and no additional latency.
Pairing either camera with a KAYA CoaXPress frame grabber yields trigger-to-image times measured in just a few microseconds, enabling eject mechanisms to actuate within a single bottle pitch. That combination makes the Iron series a strong choice for bottling, canning and other high-throughput packaging lines where every millisecond counts.
Why mechanical robustness matters on fast inspection lines
High-speed inspection stations are rarely installed in pristine labs; they live above vibrating conveyors, near pneumatic shakers and beside high-torque motors. All Iron-series cameras are therefore tested to MIL-STD-810G specifications: 75 G shock and Category 20 vibration across three axes. Optional IP67 housings with protective lens tubes seal out dust, syrup and caustic wash-down fluids, extending mean time between failures in 24/7 operations.
The Iron 4600’s aluminium body measures 75 × 75 × 44 mm and weighs only 450 g, making it light enough for robotic arms yet rigid enough to maintain optical alignment during rapid acceleration. Conversely, Iron 2011E’s compact 44 × 44 × 53 mm form factor fits easily into tight retrofit spaces such as the underside of filler wheels or between beverage cans on twin-lane conveyors. Both models offer multiple lens-mount options—C, F, EF or M42—so integrators can select off-the-shelf optics rather than costly custom designs.
Which camera best fits your application?
• If you need maximum frame rate in a small field of view—barcode grading, pin inspection, fast metrology—choose Iron 2011E. Its global shutter, 6.5 µm pixels and PoCXP support deliver more than half a thousand frames per second through a single CXP-12 cable.
• If you need ultra-high resolution—large circuit boards, flat-panel displays, contact-image sensor replacement—select Iron 4600. With 45 MP, 4.4 µm pixels, and four CXP connectors, you can capture entire panels in one shot and still receive 100 frames every second.
• If your inspection cell is physically remote from the control cabinet or subject to extreme EMI, the fibre-based Iron CoF models extend identical sensor performance over hundreds of metres with standard SFP+ transceivers, simplifying compliance in weld shops and stamping presses.
Whatever model you consider, pair it with a GenCam-compliant KAYA frame grabber to keep software integration straightforward and to unlock hardware-accelerated preprocessing. The result is lower overall system latency, higher inspection throughput and quicker return on investment.
