title: "How Accurate Does a Computer Vision Model Need to Be?"
description: "A vision model needs to be accurate enough for the decision it supports, not perfect. Set the target from the cost of a wrong answer: where mistakes are cheap it can act alone; where they are costly it should flag uncertain cases for a person. Measure it on your own images, in your own conditions."

# How accurate does a computer vision model need to be before it is useful?
A vision model needs to be accurate enough for the decision it supports, not perfect. Set the target from the cost of a wrong answer: where mistakes are cheap it can act alone; where they are costly it should flag uncertain cases for a person. Measure it on your own images, in your own conditions.
## What this means in practice
- Test on images from your real cameras, lighting and locations, not demo data.
- Separate the two kinds of error — missed items and false alarms — because they cost different things.
- Route low-confidence results to a person instead of forcing a decision.
- Re-check accuracy when cameras, sites or conditions change.
## How Lid Vizion approaches it
We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
