// Short answer

The cost of a machine vision inspection station depends on how many views and cameras the check needs, line speed, optics and lighting, the plant environment, how the result reaches your PLC and reject, and how much mechanical work is involved. addaScan does not publish fixed prices: we quote after the sample test, when the station can be specified, and can give a budget range once the application is clear.

// Cost build-up

What you are paying for

Every station quotation is made of the same building blocks. Their size changes; the list does not.

Building blocks of an inspection station cost
Building block	What it covers	What makes it larger
Sample test and engineering	Imaging your samples, station design, recipe development per product.	Many defect types or products; defects that are hard to make visible.
Vision hardware	Cameras, lenses, lighting, smart camera or PC/vision controller.	More views; higher resolution; telecentric optics; line-scan cameras.
Software licences	Inspection software and, where needed, deep-learning modules.	Deep-learning checks; several stations.
Mechanical	Mounts, brackets, shrouds and enclosures.	Washdown or dusty areas; limited space; guarding.
Electrical and PLC integration	Wiring, I/O or network connection, PLC changes, SKU selection.	New PLC logic; several signals; network protocols that need gateways.
Reject and confirmation	Air jet, pusher or diverter, reject bin, confirmation sensor.	Heavy or unstable products; no existing reject; confirmation required.
Installation, FAT and SAT	Testing before delivery, installation, testing on your line.	Short shutdown windows; several products to prove at SAT.
Training, documentation, support	Operator and technician training, handover set, support plan.	Several shifts to train; extended support terms.

// Scope levels

Three typical scopes, from simplest to largest

Relative cost only. Where your application sits is decided by the check, not by the camera.

Typical inspection station scope levels
Scope	Typical content	Typical use	Relative cost
Single-view check	One smart camera or camera with lighting; digital I/O to the existing PLC and reject.	Presence, label or code check from one side.	Lowest
Multi-view station	Several cameras and lights, PC or vision controller, recipe per product, PLC network link.	All-round label checks, several defect types, many SKUs.	Medium
Complete station	Multi-view station plus conveyor section, product handling, reject and confirmation, guarding.	New line position, or where the line has no reject.	Highest

// Cost drivers

The five things that move the price most

Number of views

Each face that must be seen needs its own camera, lens, lighting and mounting, and adds recipe work.

Line speed

Faster lines need shorter exposures, stronger or strobed lighting, reliable triggering and sometimes an encoder.

Optics

Presence and label checks use standard lenses; measurement may need telecentric lenses and matched backlights.

Environment

Washdown, dust and heat call for protected housings, cable routing and more robust mounting.

Reject and PLC work

A new reject mechanism, confirmation sensor or PLC logic change is often a large share of the scope.

// Payback

How to estimate payback with your own figures

A method, not a promise. Use conservative inputs you can defend to your finance team.

Estimate the annual net benefit: the avoidable cost of defects the station would catch (scrap, rework, returns and customer claims you can actually trace), plus inspection labour that can really be redeployed, minus the station’s running cost (support, spares, cleaning time).

Annual net benefit = avoidable quality cost + realisable labour saving − annual running costSimple payback (months) = installed investment ÷ annual net benefit × 12

Only calculate payback if both the investment and the annual net benefit are positive.
Do not count the same defective batch twice as scrap, rework and a return.
Redeploying an inspector is not a cash saving unless the cost really goes away.
Do not treat a rare worst-case recall as a yearly saving; weigh it separately.
This simple method ignores financing, tax, discounting and the ramp-up period.

// FAQ

Budget questions

How much does a machine vision inspection system cost in South Africa?

It depends on the check, not on the camera alone. A single camera looking at one face of a product is at the low end; several cameras covering every side of a round container, with a conveyor section, reject and guarding, is at the high end. We quote after the sample test, when the station can be specified, and give a budget range earlier once the application is clear.

What changes the cost of a multi-camera inspection system?

Mostly the number of views, because each view adds a camera, lens, lighting and mounting, plus processing capacity and recipe work. Line speed adds lighting and triggering effort; tight measurement adds optics; washdown or dust adds enclosures; and a new reject mechanism or conveyor changes adds mechanical and electrical work.

When does machine vision inspection pay for itself?

When the avoidable cost of the defects it catches, plus any inspection labour that can really be redeployed, exceeds the running cost within an acceptable period. Use the payback method on this page with your own figures. Be conservative: count only savings you can actually realise, and do not treat a rare worst-case recall as a yearly saving.

Why don’t you publish a price list?

Because two stations that both “check labels” can differ several-fold in scope. A published figure without the configuration behind it would mislead. When we give a budget range, it states the currency, date, assumed configuration and what is excluded.

What should a quotation state clearly?

Hardware and software included, mechanical and electrical work, PLC changes and who does them, the reject mechanism, FAT and SAT with their acceptance criteria, training, documentation, licences, support terms, delivery and installation assumptions, currency, VAT treatment, validity, and everything excluded.
