Which cow is that? The camera knows.

Every evaluation that concerns an individual cow starts with identifying her reliably. COW PROTECTOR does this with camera and AI alone. A technology developed by ACARiS.

Nothing on the animal

No collar, no pedometer, no transponder that has to be fitted, maintained or replaced.

Identified by her fingerprint

Every cow’s coat pattern is unique. The AI recognises it every time she walks past.

Linked to the ear tag

Certified ear tag reading matches every animal to her ear tag number.

The system learns new cows itself

New arrivals and heifers are learned fully automatically, without entering them by hand.

How animal identification works

Cow walks past the camera

In normal animal traffic, without stopping and without restraining.

AI reads the fingerprint

The individual coat pattern is captured and matched against the herd.

Ear tag confirms the identity

Ear tag reading links the pattern to the animal’s number.

New cows are learned

The system learns unknown animals automatically.

The animal ID is ready

For lameness, BCS, areas and counting, in the dashboard.

The hardware

Two compact cameras at a suitable spot

Simply screw on, plug in and connect. No server on the farm. ACARiS takes care of the installation.

The walkway in the picture is just an example. Any spot works where the cows pass and both cameras can be mounted close to each other, for example:

  • Walkway
  • Water trough
  • Rotary parlour
  • Barn entrance and exit

What the camera sees

Live detection

Every cow in the picture gets her own ID, even when several animals are in view at the same time.

  • A unique ID for every cow, with a confidence score
  • Ear tags are found and read in the image
  • Several animals in view at once

The basis for everything you want to know about an individual cow

Once every cow is identified reliably, every observation can be assigned to one animal. All COW PROTECTOR functions build on this.

Lameness Detection
Assess the gait of every cow

A score from 1 to 5 on every pass, with a trend for each animal.

Body Condition Scoring
Body condition of every cow

Recorded regularly and automatically, as a development over time.

AreasON REQUEST
Who comes, who goes

See which cow enters or leaves an area, with the time.

CountingON REQUEST
Count animals automatically

How many cows are in the barn, how many are outside? No counting by hand.

Which cow was on pasture, and when?

The question you have always wanted to ask your herd: which cows left the barn at what time, and when did they come back? With a camera at the gateway, the animal ID answers it automatically.

  • Turn-out and return for each cow, with the time
  • See at any time how many animals are where
  • No sensor, no reader at the gate

Key questions at a glance

Does the cow need a sensor or transponder?

No. Identification works by camera and AI alone. No collar, pedometer or transponder is needed.

How accurate is the identification?

Across more than 6,000 cows measured in daily operation, 98% of the cows that walked past the camera were correctly identified from the camera image alone.

What happens when new cows join the herd?

The system learns new animals fully automatically. Nobody has to take photos or enter animals by hand.

How is a cow matched to her ear tag number?

Certified ear tag reading reads the ear tag in the camera image and links it to the cow’s coat pattern.

What can I use the animal ID for?

It is the basis for lameness detection and BCS measurement. Beyond that, it detects which cow enters or leaves an area, and it counts the animals.
