The Basler ace 2 a2A2048-114umPRO is a high-speed USB3 Vision area scan camera built on the 3.2 MP Sony IMX900 global shutter CMOS sensor (2048 x 1536 px, 2.25 um pixels, 1/3.1" format, Sony Pregius S). It delivers 114 fps in monochrome over USB 3.0 and covers the visible and NIR spectrum. Powered via the USB 3.0 interface or 12-24 VDC, C-mount.
The Basler ace 2 a2A2048-114umPRO is a high-speed area scan camera built on a 3.2 MP Sony IMX900 global shutter CMOS sensor (Sony Pregius S) with a 1/3.1" optical format and 2.25 um pixels. Its defining trait is speed: it delivers 114 frames per second at full 2048 x 1536 resolution, and the global shutter exposes every pixel at the same instant, so fast-moving parts are frozen without the skew or smear a rolling shutter would introduce.
It is a monochrome camera, which on contrast-based inspection gives higher effective resolution and light sensitivity than a colour sensor of the same format, and its spectrum covers the visible and near-infrared range. The combination of high frame rate, global shutter and a small, light-efficient pixel suits inline inspection where parts move quickly past the field of view.
The camera connects over USB3 Vision and is GenICam-compliant, so it integrates with any USB3 Vision/GenICam software stack and is configured through standard feature interfaces. A single USB 3.0 cable carries image data, and the camera can be powered over the USB 3.0 interface or via 12-24 VDC. The C-mount gives access to a broad ecosystem of industrial lenses. It is also Rosepetal-ready for deep-learning inspection workflows.
Best for
High-speed inline inspection of parts moving quickly on a conveyor or indexing line, where the global shutter freezes motion cleanly
Surface inspection at line speed (scratches, dents, finish defects) where short exposures and high frame rates are needed
AI-based defect detection on fast-moving product, feeding a stable monochrome image to a deep-learning model
Applications where monochrome contrast (not colour) defines the defect and maximum sensitivity matters
Selection notes
The C-mount accepts a wide range of industrial lenses; match the lens image circle to the 1/3.1" sensor format and ensure it resolves down to the 2.25 um pixel pitch so the optics are not the limiting factor.
Freezing fast motion means short exposures, so budget enough light: high-intensity or strobed lighting synchronised to the trigger keeps exposures short while maintaining signal.
Plan the USB3 Vision link: use a certified USB 3.0 cable within length limits and a host controller with enough sustained bandwidth to avoid dropped frames at 114 fps.
If the task needs colour information, or substantially higher resolution, or cable runs beyond USB3 distances, consider a colour, higher-resolution, or GigE/CoaXPress model instead.

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
It delivers up to 114 fps at its full 3.2 MP resolution over USB3 Vision, which makes it suitable for high-speed inline inspection of moving product.
Yes. It uses a Sony IMX900 global shutter sensor (Sony Pregius S), which exposes all pixels at the same instant and avoids the motion skew of rolling-shutter sensors when imaging moving parts.
It is a monochrome camera with 3.2 MP resolution (2048 x 1536 px), sensitive across the visible and near-infrared spectrum. Monochrome gives higher effective resolution and sensitivity for contrast-based inspection.
It is a USB3 Vision (GenICam) camera connected with a USB 3.0 cable, and can be powered over the USB 3.0 interface or via 12-24 VDC. It has a C-mount.
