Data acquisition demands of security monitoring in HRTH.
| Level | Description | Concern | Data acquisition demands |
| First level | Key area monitoring | Focus on the security of key, important, and sensitive areas | The data of key areas in HRTH must be continuously acquired and can meet the anomaly detection of key areas |
| Second level | Passenger line monitoring | Focus on the security of passenger input and output lines | The data of entire passenger line in HRTH must be continuously acquired and can meet the forecast demands of post node in passenger line |
| Third level | Complete coverage monitoring | Focus on the security of whole HRTH | The data of whole HRTH can be inconsecutively and optionally acquired and must ensure all function areas are completely covered |
