Choosing between a color camera with a friendlier price and a higher-resolution monochrome camera is a classic machine vision identification decision. Both of these used USB 3.0 C-mount models plug into existing industrial imaging setups, but they favor different jobs: the Point Grey/FLIR Flea3 delivers 8.8MP color at 21 fps, while the Basler acA5472-17um captures 20MP in monochrome at 17 fps. Your choice comes down to whether color inspection or maximum pixel detail matters more for your application.
Quick Verdict
If your identification tasks need to distinguish colors - think circuit board components, wire insulation, or printed labels - the Point Grey/FLIR Flea3 is the pragmatic pick at USD 225.00. If you can work in grayscale and need the finest possible detail for precision measurement or barcode reading, the Basler's 20MP sensor gives you more resolving power for USD 449.99.
Comparison at a Glance
| Product | Listed Price | Price Bar | Resolution | Frame Rate | Sensor Type |
|---|---|---|---|---|---|
| Point Grey/FLIR Flea3 FL3-U3-88S2C-C | 8.8MP Color | USD 225.00 | 8.8 MP (4096 x 2160) | 21 fps | Color CMOS | |
| Basler acA5472-17um | 20MP Mono | USD 449.99 | 20 MP (5472 x 3648) | 17 fps | Monochrome CMOS |
Both cameras use a C-mount and connect over USB 3.0, so they fit similar lenses and interface hardware. The Basler adds a Hirose 6-pin I/O connector for triggering and external device integration, which can be important in synchronized machine vision systems.
Where Each Camera Wins
The Flea3 wins on price and speed. It costs roughly half the Basler's listed price and captures frames at 21 fps, useful for faster-moving objects or inspection lines that need a higher frame rate. It also provides color, which is essential if your identification logic relies on hue or color contrast.
The Basler wins on resolution. At 20MP with 5472 x 3648 pixels, it offers more than double the pixel count of the Flea3. That extra detail can help you read smaller text, detect fine defects, or measure dimensions with greater confidence. The monochrome sensor also simplifies illumination and often produces sharper grayscale contrast than a color sensor with a Bayer filter.
Product Notes
Point Grey/FLIR Flea3 FL3-U3-88S2C-C
The Flea3 is listed at USD 225.00 and described as lightly used. It pairs an 8.8MP Sony IMX121 sensor with a 32MB frame buffer, which helps stabilize USB 3.0 transfers. For color inspection in robotics, industrial inspection, or scientific imaging, this camera gives you a good combination of resolution and 21 fps speed without stretching your budget. The main limitation is that the listing covers only the camera body - a C-mount lens and a locking USB 3.0 cable are not included. Plan for those extras before you can image. If color is not needed, the lower resolution may also leave you wanting more detail.
Basler acA5472-17um
The Basler acA5472-17um is listed at USD 449.99 and is a used monochrome camera built around a 20MP Sony IMX183 CMOS sensor. It delivers a wide 5472 x 3648 field of view at 17 fps, and the rear Hirose 6-pin I/O connector supports triggering and system integration. That makes it a strong option for precision monochrome identification tasks where every pixel matters. The listing states that no functional testing was performed, so you should factor that into your purchase decision. The housing shows normal wear with a small dent on one side, and no lens, USB cable, or mounting hardware is included.
Final Choice by Use Case
Choose the Point Grey/FLIR Flea3 if you need color imaging for machine vision identification, want a lower entry price, and can work with 8.8MP resolution. It runs faster and leaves room in your budget for the required lens and cable.
Choose the Basler acA5472-17um if your identification tasks demand maximum monochrome resolution, you need a Hirose I/O connection for triggering, and you are willing to spend more and accept the untested used condition. For fine-detail grayscale inspection, the 20MP sensor gives you the edge.
