Hi, everyone!
Good day to you!
In this article, I will choose two popular cameras and compare them, and then introduce their application scenario.
The M-series camera, from the origin of its name, is a cost-effective camera. At a beautiful price while meeting the customer's requirements.

| Target | Target detection/Target enhancement/Target attribute recognition/Target recognition |
| Person | Person detection/Personal attribute recognition |
| Non-motorized vehicle | Object classification/Cyclist attributes |
Application Scenario
What is 1+N
Smart One+N is a new collaborative networking architecture of multiple non-intelligent cameras and smart cameras.
It uses an intelligent camera with ultra-high computing power as the host. The host performs access decoding, target recognition and tracking, and snapshot video structuring on N traditional HD slave cameras in the same network segment while completing its own services. Provides video parsing capabilities for non-intelligent cameras.
Image enhancement
Image enhancement makes images clearer in foggy environments. When the picture shakes, most of the picture remains relatively stable. It also reduces noise.
Traffic flow statistics
Through traffic flow statistics, you can view the traffic flow in a specified period. including the number of vehicles passing through each lane in a specific time period, vehicle type, average speed, queue length, distance between vehicles, and congestion.
Behavior analysis( Including Fast movement/Tripwire crossing/Intrusion/Area entry or exit/Loitering)
Loitering Detection: Outdoor campuses or indoor halls. When a person is loitering in a detection area for a specified time period, an alarm is generated.
Tripwire Crossing Detection:
Wrong-way movement detection on entrances and exits of museums or subway stations.
Intrusion detection at key locations of campuses.
Area Entry/Exit Detection:
Outdoor campuses or indoor halls. When an object enters or leaves a detection area, an alarm is generated.
Fast Movement Detection:
Outdoor squares, bus stations, and sidewalks. If an object moves fast in a detection area, an alarm is generated.
