Detecting people not wearing seatbelts or talking on the phone are 2 areas that have been marketed as being advanced uses of video analytics.
Now, Dahua has included seatbelt and phone detection in their new WizMind line, but how well do they work?
We tested seatbelt and phone detection in the IPC-HDBW7442H-ZFR, examining:
- Are these analytics accurate in ideal conditions, e.g., low angles and high PPF?
- How do harsher angles affect accuracy?
- How do shadows and glare impact detection?
- Does it falsely detect raised arms as phones or seatbelts?
