We use the same research process for every guide so readers can see how a recommendation was reached. Unless an article states that we tested a product ourselves, our guides are research-based and we do not claim hands-on testing.
What we look at
- Sensor and resolution. Thermal resolution, sensitivity, refresh rate and image processing.
- Range and optics. Stated detection range, lens options, zoom and field of view.
- Use case fit. Home inspection, hunting, outdoor use or smartphone add-ons, and what each needs.
- Build and battery. Weather resistance, battery life, storage and display quality.
- Rules and warranty. Local rules about use, export limits where stated, and warranty terms.
- Value. What the product offers for its price tier. We do not show prices because they change often; check Amazon for current details.
Sources
We draw on manufacturer specification sheets and manuals, published reviews, buyer feedback and community discussion.
