The Basler ace 2 a2A1920-51gcPRO is a GigE area scan camera built around the 2.3 MP Sony IMX392 global shutter CMOS sensor (1920 x 1200 px, 3.45 um pixels, 1/2.3" format). It outputs color images at 51 fps over Gigabit Ethernet and is powered via PoE or 12-24 VDC. C-mount, typical power consumption 3.4 W.
The Basler ace 2 a2A1920-51gcPRO is a 2.3 MP area scan camera built on a Sony Pregius IMX392 global shutter sensor with a 1/2.3" optical format and 3.45 um pixels. The global shutter exposes every pixel simultaneously, so fast-moving parts are captured without the skew, smear or geometric distortion that a rolling shutter would introduce. Combined with a 51 fps frame rate, this makes the camera well suited to inline inspection on moving product, conveyors and indexing stations where each part must be frozen cleanly for measurement or classification.
Color output adds chromatic information that monochrome sensors discard, which is valuable where defects, print, labels or product variants are distinguished by hue rather than contrast alone. The 3.45 um pixel on a 1/2.3" format strikes a balance between resolution density and per-pixel light collection, and the 1920 px horizontal resolution provides enough detail for typical defect, character and packaging inspection fields of view without moving into very high resolution data rates.
The camera connects over GigE Vision and speaks the GenICam standard, so it integrates with any GigE Vision/GenICam-compliant software stack and is configured through standard feature interfaces rather than a proprietary API. A single standard Ethernet cable carries image data, and Power over Ethernet lets the same cable also deliver power, simplifying wiring on machines where a separate power feed is awkward. The C-mount provides access to a broad ecosystem of industrial lenses. The camera is also Rosepetal-ready for streamlined integration into Rosepetal AI vision workflows.
Best for
AI-based surface and defect inspection of moving or indexed parts, where the global shutter freezes motion cleanly
Industrial OCR/OCV on printed codes, labels and date/lot markings passing through the field of view
Packaging inspection: verifying print, color, fill, seals and label presence at line speed
Color-dependent sorting and verification where defects or variants are distinguished by hue
General-purpose machine-vision tasks on conveyors or rotary tables needing distortion-free capture at moderate frame rates
Selection notes
The C-mount accepts a wide range of industrial lenses; match the lens image circle to the 1/2.3" sensor format and select focal length from your working distance and required field of view, ensuring the lens resolves down to the 3.45 um pixel pitch to avoid being the limiting factor.
As a color camera the sensor uses a color filter array, which reduces effective spatial resolution and light sensitivity versus a monochrome equivalent; if the task is purely geometric/contrast-based and color carries no information, a monochrome variant typically gives sharper, more light-efficient results.
Plan the GigE Vision network: use a quality Ethernet cable within standard length limits and a NIC that supports jumbo frames, and confirm your PoE source provides adequate power for the camera.
For motion applications, size lighting and exposure together: a global shutter freezes motion only if exposure is short enough relative to part speed, so budget sufficient illumination and consider strobed lighting to keep exposures short while maintaining signal.
If the application needs substantially higher throughput, larger fields at fine detail, or more bandwidth than the GigE Vision interface provides, consider a higher-resolution model or a faster interface; this camera targets moderate-resolution, moderate-speed inline inspection.

Applications this camera is commonly selected for. Open one to see the full recommended hardware and approach.
Get a first image quickly with the pylon Viewer, then move into the pylon SDK for your application. These cameras are GenICam/GenTL-compliant, so any compliant vision software can drive them as well.
Download and install the pylon Camera Software Suite for your OS from Basler. This provides the pylon Viewer, the GenTL transport-layer producers and the pylon SDK (C/C++/.NET/Python). On Windows the installer adds the needed drivers; on Linux follow the included setup notes for USB and network permissions.
2. Connect the camera and check the link
Cable the camera to its matching interface: GigE Vision to a GigE port (use a quality cable and, ideally, a dedicated NIC with jumbo frames enabled), USB3 Vision to a USB 3.x port with the supplied cable, or CoaXPress to the frame grabber. Provide power where required (PoE, USB bus power, or PoCXP). Open the pylon Viewer and confirm the camera appears in the device list; for GigE, make sure the camera and NIC are on the same subnet.
3. Grab a first image and set exposure, gain and pixel format
Select the camera in the pylon Viewer and start a continuous grab. Adjust exposure time and gain until the image is well exposed (avoid clipped highlights), set the pixel format (e.g. Mono8 or a Bayer/RGB format), and focus the lens. Use a test pattern if the lens or scene is not ready yet.
4. Configure triggering and acquisition
Decide between free-run and triggered acquisition. For synchronized capture, set the trigger source (software or a hardware line on the I/O connector), trigger mode and any debounce or exposure mode, then verify timing. Note the parameter names you change in the Viewer feature tree, as you will reuse them in code.
5. Move to the SDK or a GenICam-compliant library
Recreate your settings in code with the pylon SDK (C, C++, .NET or Python) to open the device, apply the same features and pull frames into your pipeline; pylon vTools and pylon AI can add processing blocks. Because the cameras are GenICam/GenTL standard, third-party vision libraries work too. Once the image stream is stable, you can route frames to a deep-learning inspection such as Rosepetal for automated defect detection.
Frequently asked questions
Yes. It uses a Sony Pregius IMX392 global shutter sensor, which exposes all pixels at the same instant. That eliminates the motion skew and distortion of rolling-shutter sensors, making it suitable for imaging moving parts on conveyors and indexing lines.
It is a GigE Vision camera using the GenICam standard, connected over Ethernet with a standard Ethernet cable. It supports Power over Ethernet (PoE), so a single cable can carry both image data and power.
It is a color camera with 2.3 MP resolution and 1920 px horizontal resolution. Color output helps where defects, print or product variants are distinguished by hue rather than contrast alone.
It has a C-mount and a 1/2.3" sensor format with 3.45 um pixels. Choose a C-mount lens whose image circle covers the 1/2.3" format and whose resolving power matches the pixel pitch.
It delivers up to 51 fps. Combined with the global shutter, this supports inline inspection of moving product where each part must be captured without motion blur or distortion.
