AI-102 Implement computer vision solutions Practice Question
You need to analyze a live video stream from a security camera to detect people entering a restricted area. Which Azure AI service should you use?
⚠ Common exam trap
Candidates may confuse Azure Video Indexer with the deprecated Azure Video Analyzer for Media, or incorrectly assume that Azure AI Face API is sufficient for person detection in video streams without understanding its facial recognition focus.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Video Indexer
Azure Video Indexer supports live video stream analysis for detecting people in restricted areas using pre-built AI models. It can process live streams and generate alerts in real time. Azure Video Analyzer for Media is a deprecated predecessor and is not the optimal choice. Custom Vision requires custom model training, and Face API focuses on facial recognition rather than general person detection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Video Indexer
Why this is correct
Azure Video Indexer analyzes recorded videos, not live streams, making it unsuitable for real-time detection.
- ✗
Azure AI Custom Vision
Why it's wrong here
Custom Vision is designed for static images, not live video streams.
- ✗
Azure Video Analyzer for Media (deprecated)
Why it's wrong here
Azure Video Analyzer for Media can analyze live video streams and detect people without custom training, making it the correct choice.
- ✗
Azure AI Face API
