One view, one check
A single code read, a presence check or a label check on one face usually fits a smart camera. Fewer parts means fewer things to fail.
Guides
Smart camera or PC-based vision?
Both work. The right one depends on how many cameras the job needs, how fast the line runs, and who will keep it running after startup.
What is the difference?
A smart camera holds the sensor, the processor and the inspection software in one housing. A PC-based system uses one or more industrial cameras wired to an industrial computer that runs the software. The first is simpler to mount and swap. The second has more computing power and can combine many cameras in one decision.
When does each one fit?
Several views, one decision
Checking all sides of a pack, or combining a code read with a label check, fits a PC system better. One computer sees every image and makes one pass or fail.
Deep learning
Learned models need more processing than most smart cameras carry. A PC with a graphics card runs them at line speed.
High speed or high resolution
Line-scan cameras and very high pixel counts move a lot of data. That data goes to a computer, not a smart camera.
Maintenance on site
A smart camera can be swapped by a technician with a saved job file. A PC needs someone comfortable with backups, updates and drive images. Plan for that before you choose.
Upgrade path
Smart cameras change models every few years, and old job files do not always move over. A PC system can change cameras without rewriting the whole inspection.
We still recommend a single smart camera when it is the simpler answer. The goal is the station your team can run, not the most powerful one.
FAQ
Common questions
QIs a PC system less reliable?
Not when it is an industrial computer with no moving parts, a protected drive image and a UPS. Office PCs on the line are a different story.
QCan we mix both?
Yes. A common setup uses smart cameras for simple reads and a PC for the hard checks, all reporting to the same PLC.
QWhich is cheaper?
For one simple check, a smart camera. Once a job needs three or more cameras or learned models, a PC system often costs less per camera.
QCan an old smart camera be replaced with a PC system?
Yes. It is a common upgrade when the old camera is end-of-life or the check outgrew it.
