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.
No collar, no pedometer, no transponder that has to be fitted, maintained or replaced.
Every cow’s coat pattern is unique. The AI recognises it every time she walks past.
Certified ear tag reading matches every animal to her ear tag number.
New arrivals and heifers are learned fully automatically, without entering them by hand.
In normal animal traffic, without stopping and without restraining.
The individual coat pattern is captured and matched against the herd.
Ear tag reading links the pattern to the animal’s number.
The system learns unknown animals automatically.
For lameness, BCS, areas and counting, in the dashboard.
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:



Example walkway, camera image from above: the AI identifies the cow as she passes. The green box marks the identified animal.

Every cow in the picture gets her own ID, even when several animals are in view at the same time.
Camera image with live detection of cows and ear tags.
Once every cow is identified reliably, every observation can be assigned to one animal. All COW PROTECTOR functions build on this.

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

Recorded regularly and automatically, as a development over time.

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

How many cows are in the barn, how many are outside? No counting by hand.
| Time | Cow | Event |
|---|---|---|
| 06:12 | Cow 214 | Barn → pasture |
| 06:12 | Cow 087 | Barn → pasture |
| 06:14 | Cow 152 | Barn → pasture |
| 11:48 | Cow 087 | Pasture → barn |
| 17:31 | Cow 214 | Pasture → barn |
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.
No. Identification works by camera and AI alone. No collar, pedometer or transponder is needed.
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.
The system learns new animals fully automatically. Nobody has to take photos or enter animals by hand.
Certified ear tag reading reads the ear tag in the camera image and links it to the cow’s coat pattern.
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.
