The success of a machine vision quality control project depends largely on choosing the right supplier. Quotes for the same product can differ widely in scope, hardware and support. The questions below make the comparison easier.

Do they test your product?

A good supplier wants to see your product before quoting. They test how the defect appears to the camera using samples or photos taken on the line. Firm prices and performance promises given without seeing the product should be treated with caution.

Do they have a similar application?

Ask whether the supplier has worked on a similar product or defect type before. Even if the customer name cannot be shared, they can explain how the application works and show the system running on site.

Is the scope clearly written?

The quote should clearly cover:

  • Defect types to be inspected and acceptance criteria
  • Hardware list including camera, lens, lighting and computer
  • Mechanical mounting, enclosure and rejector
  • Integration with the PLC and production systems
  • Commissioning, training and acceptance test

A vague scope means extra cost and delays as the project progresses.

Is the accuracy target realistic?

No system is error-free under all conditions. A good supplier agrees with you on the balance between missed defects and false rejects and measures both with real products during the acceptance test. Absolute promises such as "catches every defect with zero false rejects" are not realistic.

How are product changes handled?

When a new product arrives or an existing one changes, it matters who adds it to the system and how. Ask whether operators can create a new product recipe themselves and how many samples that takes.

Where are the images stored?

Production images are your company's data. Check whether the system runs on site without an internet connection and where the records are stored.

Support and availability

After installation you need fast support during line stops or criteria changes. Remote support, response time on site and spare parts should be discussed at the quoting stage.
