The Basler a2A2448-23gm is an ace 2 R-series industrial area scan camera using a 1/1.8" Sony IMX547 Pregius S global shutter CMOS sensor with 2448 x 2048 pixel resolution (5 MP) and 2.74 µm square pixels. It connects over a Gigabit Ethernet (GigE Vision 2.0 / GenICam) interface via an RJ45 connector and reaches roughly 23 fps at full resolution with 8/10/12-bit output. The camera uses a C-mount, is powered by PoE (IEEE 802.3af) or 12-24 VDC through an M8 6-pin I/O connector, and has a typical power draw around 2.8 W. It measures 29 x 29 mm in cross-section, weighs about 100 g, and is rated IP30.
The Basler ace 2 a2A2448-23gm is a 5 MP monochrome area scan camera built around the 1/1.8" Sony IMX547 Pregius S global shutter CMOS sensor, delivering 2448 x 2048 pixels of 2.74 um square pixels. The global shutter is the defining trait for an installer: every pixel is exposed simultaneously, so parts moving past the camera or objects on a fast indexing line are captured without the geometric skew that a rolling shutter introduces. Combined with the monochrome sensor (no Bayer filter, so full per-pixel resolution and higher light sensitivity), this camera is purpose-built for precise edge detection, defect contrast and code reading rather than color-dependent grading. The 8.8 mm sensor diagonal on a 1/1.8" format keeps it within the comfortable image circle of standard C-mount optics.
The camera connects over Gigabit Ethernet using GigE Vision 2.0 and GenICam through an RJ45 connector, which is the practical workhorse choice for factory floors: cable runs reach up to about 100 m without repeaters, the standard is widely supported by every major vision library, and a single Cat-5e/Cat-6 cable can carry both data and power when used with a PoE (IEEE 802.3af) switch or injector. Alternatively the camera accepts 12-24 VDC through its M8 6-pin I/O connector, which also provides the hardware trigger and strobe lines needed to synchronize exposure to an encoder pulse, photoelectric sensor or strobed illuminator. At full 2448 x 2048 resolution it runs roughly 23 fps with selectable 8/10/12-bit output, so an installer can trade bit depth and region-of-interest height for higher frame rates when cycle time matters more than dynamic range.
Physically the camera is a compact box-housing unit measuring 48.9 x 29 x 29 mm, weighing about 100 g, drawing roughly 4 W, and rated IP30 for an operating range of -10 to 60 C. The IP30 rating is the key integration caveat: this is a clean-environment camera that needs an enclosure if it will see dust, washdown or coolant mist. With a C-mount and a 2.74 um pixel, lens selection is critical because the optics must resolve detail at this pixel pitch; pairing it with a megapixel-rated C-mount lens chosen for the required field of view and working distance is what unlocks the full 5 MP. For demanding contrast tasks, the global shutter pairs naturally with a strobed LED illuminator triggered through the M8 I/O so motion is frozen with a short, bright flash.
Best for
Inline defect and surface inspection on moving or indexed parts where the global shutter freezes motion without distortion
OCR/OCV of printed text, lot codes and date stamps where monochrome resolution maximizes character contrast
Reading 1D/2D traceability codes (DataMatrix, barcodes) on packaging and components at line speed
Dimensional and gauging measurement where the full 2448 x 2048 monochrome grid provides accurate, color-independent edge location
Electronics and semiconductor inspection in clean assembly cells where a compact PoE GigE camera simplifies cabling
Selection notes
Plan the optics around the 2.74 um pixel and 8.8 mm sensor diagonal: use a megapixel-rated C-mount lens sized to your field of view and working distance, or fine detail at 5 MP will be lost to the lens rather than the sensor.
Confirm the IP30 rating suits the environment; for dust, mist or washdown the camera needs a protective enclosure since it offers no inherent ingress protection.
Budget the GigE link: at full resolution and 23 fps you need a Gigabit-capable NIC/switch and Cat-5e or better; a PoE (802.3af) source removes the separate power supply, otherwise wire 12-24 VDC to the M8 connector.
For motion freezing on fast lines, route a hardware trigger and strobe through the M8 6-pin I/O and pair the global shutter with a strobed illuminator rather than relying on continuous light.
This is a monochrome sensor; if the application depends on distinguishing colors, choose a color variant instead. Use the 8/10/12-bit output and ROI to trade dynamic range against frame rate when cycle time is tight.

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 is monochrome. The Sony IMX547 sensor has no color filter array, which gives full per-pixel resolution and higher light sensitivity, making it ideal for contrast, edge and code-reading tasks rather than color grading.
Global shutter. All pixels are exposed at the same instant, so parts moving on a conveyor or indexing line are captured without the skew or smear of a rolling shutter.
It is a 5 MP camera at 2448 x 2048 pixels and reaches roughly 23 fps at full resolution. Selectable 8/10/12-bit output and region-of-interest cropping let you push higher frame rates when needed.
It uses a Gigabit Ethernet (GigE Vision 2.0 / GenICam) interface over an RJ45 connector. It can be powered by PoE (IEEE 802.3af) over the same cable or by 12-24 VDC through the M8 6-pin I/O connector, drawing about 4 W.
It has a C-mount, so it accepts standard C-mount machine-vision lenses (choose megapixel-rated optics for the 2.74 um pixel). It is rated IP30, meaning it is intended for clean environments and needs a protective enclosure where dust, mist or washdown are present.
