Why it matters

Manual counting and simple sensors fail when the flow changes

On a conveyor, objects can move in dense flows, partially overlap, and differ by shape, color, packaging, orientation and speed. A simple photoelectric sensor counts a line crossing, but it does not understand the object class, duplicate counting, empty positions, rejects, packaging defects or mixed flows.

  • quantity errors by shift, batch and line;
  • no separation by class, type, color, geometry and quality attributes;
  • label shifts, contamination, print defects, packaging damage and marking errors are not captured;
  • the operator sees the issue too late, after the batch has moved further down the line.
STATANLY solution

Detector + counter + quality control + operator UI

The system analyzes video from an IP or industrial camera, detects objects, tracks their movement, removes duplicate counts, classifies products and captures defect indicators. Objects, analysis zones and inspection logic are configured in the interface: by line, area, control zone or production event.

  • counting items, parts, packages, raw materials and semi-finished products;
  • classification by type, color, shape, size and quality attributes;
  • detection of packaging, marking, geometry, completeness and surface-condition defects;
  • integration with conveyors, accounting systems, reject mechanisms and production equipment.
Capabilities

From a simple counter to in-flow product quality control

The solution can be deployed step by step: start with quantity control on one line, then add product classes, presence checks, quality attributes, defect detection, integrations and reports.

Object counting

Recording every object as it crosses a control line or passes through an analysis zone without stopping the conveyor.

Product classification

Separating objects by type, color, size, shape, packaging, orientation, SKU and quality attributes.

Geometry and condition

Assessing dimensions, shape, position, skew, non-standard objects and clearly visible deviations.

Presence / absence

Checking empty positions, omissions, completeness and the presence of an item in a cell, box, blister or on the belt.

Rejects and visual defects

Detecting packaging damage, contamination, label shift, print defects, wrong shape and suspicious items.

Events and control

Sending counters, alerts, statuses and Warning / Reject / Alarm events to SCADA, MES, ERP, PLC, HMI, BI or reject systems.

Interface and analytics

The operator sees the flow, counters, product classes, defects and proof frames

The interface combines video streams, counting zones, event logs, class distribution, shift and line statistics, camera settings, defect frames and integration parameters.

Example scenarios

Counting bread, packages, parts and defect control in mixed flows

The system applies to food production, agriculture, warehouses, packaging and industrial assembly. In one contour it can count objects, classify them and detect rejects: damage, contamination, wrong orientation, missing components, print defects or non-standard shape.

Counting white bread on a conveyor
Food production

White bread counting

The system records items in the flow, excludes duplicate counts and sends quantities by line, shift or batch. It can also flag non-standard shape, damage and visible rejects.

Counting and classifying dark bread
Product classification

Counting dark bread and different product types

The AI detector separates product classes in one video stream, creates counters for each class and can highlight suspicious items for quality inspection.

Counting end pieces and non-standard objects on a conveyor
Food production

Counting end pieces and non-standard objects

The solution works with objects of different shapes and orientations where simple sensors cannot classify reliably, and helps detect deformation or unusual geometry.

Counting chips on a production line
Packaging and FMCG

Counting chips, packages and small items

The scenario fits flow control before filling, packaging, sorting or transfer to the next area, including contamination, damage and incomplete package detection.

Counting chicks and moving objects
Agriculture and livestock

Counting chicks and moving objects

The system counts moving objects correctly even when they change position or briefly overlap each other.

Counting and defect control for dairy packages
Dairy products

Package counting and reject detection

Package counting can be combined with integrity checks, contamination detection, label shift, print defects and signs of seal failure.

Efficiency analysis and object distribution by classes
Meat processing

Counting products and operations

The system counts packages on the production line, monitors basic sorting operations and helps capture distribution errors or class deviations.

Efficiency and KPI control on the conveyor
Meat processing

Efficiency control, statistics and KPIs

Counting operations, shifts and batches by lines, operators and production modes, with the ability to highlight losses and deviation causes.

Quality control

Which defects can be detected together with counting

In packaging-control projects, the model can count an object and assess its condition at the same time. This creates a single loop: object detected, classified, checked for quality, event saved, and, if needed, a reject signal sent.

Packaging

Integrity, contamination and sealing

Torn packaging elements, contamination, product residue on the outer surface, signs of seal failure and systematic packaging rejects.

Marking

Print, date and readable information

Defects or missing human-readable print, date and expiration marking errors, poor flexographic printing and label displacement.

SKU

Match, position and completeness

Label or insert mismatch with SKU, back-label displacement, missing component, wrong orientation, non-standard shape and suspicious object.

Hardware and software complex

Camera, lighting, compute node, database and integration module

Reliable counting and defect control depend not only on the model, but also on a stable inspection point: the right camera, lighting, protection, working distance, line synchronization and exception rules.

Deployment

From one counting point to a network of conveyor lines

We recommend starting with a pilot on one line: confirm accuracy, product classes, defect types, capture conditions and integration, then scale to other areas.

1

Survey

Define the counting object, product classes, defect types, line speed, capture conditions and reporting requirements.

2

Pilot

Collect examples, configure the model, analysis zones, counters, filters, defect indicators and operator interface.

3

Acceptance

Fix accuracy metrics, rules for ambiguous cases, exceptions, defect types and operation requirements.

4

Scaling

Add lines, classes, new scenarios, integrations and a unified production analytics center.
