DEFICIENT

Winnowl Index

Winnowl Verdict

Even though the eufy C120-3C Indoor Security Camera just cleared our audit with a DEFICIENT (47) Winnowl Index, that score is really a sign that you're paying for the name on the box more than the actual features you're getting. You’re looking at an Average Performance and Weak Value product here, but it’s coming from a company with Strong Brand Strength, so you're definitely paying a premium just for that name on the box. If you're looking at the eufy C120-3C Indoor Security Camera 2K, Three-Cam Kit, Two-Way Audio, Human/Pet AI, the specs show that you should find the clarity sufficient for standard indoor monitoring, providing a crisp 1080p image that handles most lighting well simply because that Resolution of 2 MP sits 54% below the class average. Honestly, we’d suggest a hard pivot from this Brand Tax product; that 69% higher price tag results in 33% less hardware for your dollar than the class average, so you're really not getting much for the extra cash.
