• IDs triggers → CCTV review: the intrusion alarm is automatically associated with the nearest camera, and the pop-up window displays the real when screen to assist security personnel to quickly confirm the scene.
• FAS triggered → ACS release: Fire alarm linkage access control system automatically opens the evacuation channel to ensure the rapid evacuation of personnel.
• FAS triggered → CCTV confirmation: fire alarm linkage video review to confirm the fire after starting smoke exhaust and fire linkage.
• ACS abnormal → IDs linkage: The access control abnormality is turned on to trigger the intrusion detection alarm, and the linkage video tracking is convenient for after-the-fact forensics.

Network bearer layer key capabilities

• Industrial Ethernet ring network: The redundant ring network carries all subsystem data streams, and the 50-millisecond failure self-healing guarantees that the security data is continuous.
