CCTV CCTV Video Analytics and Advanced Features 2

Question 1

What does 'people counting' analytics in CCTV measure?

Accepted Answer

The number of individuals entering or exiting a defined area or crossing a line

Answer

People counting analytics uses video processing to accurately count individuals entering or exiting a space, useful for occupancy management and retail analytics.

Question 2

In video analytics, what is 'object classification'?

Accepted Answer

The ability to distinguish between different types of detected objects such as person, vehicle, or animal

Answer

Object classification uses machine learning to identify and label detected objects as specific categories (person, vehicle, bicycle, etc.) to reduce false alarms from non-relevant motion.

Question 3

What is a 'heat map' generated by CCTV analytics used for?

Accepted Answer

Visualizing areas of high activity or movement frequency over time

Answer

Analytics heat maps use color overlays on the camera image to show which areas of the scene have experienced the most activity over a defined time period.

Question 4

What advantage does edge-based video analytics (processing on the camera) offer compared to server-based analytics?

Accepted Answer

Reduced bandwidth and server load since processing occurs locally at the camera

Answer

Edge analytics performs video processing inside the camera itself, sending only metadata or alerts to the server, which significantly reduces network bandwidth usage.

Question 5

What is 'facial recognition' in a CCTV analytics system designed to do?

Accepted Answer

Match captured faces against a database to identify or flag specific individuals

Answer

Facial recognition analytics extracts biometric facial features from video frames and compares them against an enrolled database to identify or flag persons of interest.
