Hanwha WiseDetector Train Your Own Analytics Tested
Hanwha's WiseDetector train-your-own analytics, if it works well, would deliver advanced analytics that many have tried but have yet to do well, from our previous testing. But how well does Hanwha's work?
We tested WiseDetector, a free "machine-learning-based feature" that is available on P-Series cameras that we bought, examining:
- How effective is it at detecting objects once they are trained?
- How many training images does it need for accurate detection?
- How accurate is it in scenes with depth?
- How accurate is it with objects that change shape?
- Does it detect multiples of an object after training?
- How well does it detect the trained objects in different colors?
- Is training done on-site or in the cloud?
- How does it compare to other offerings in this segment?
