The Chinese AI police tech aimed at physical, psychological and emotional states

Chinese artificial intelligence technology capable of assessing suspects' physical health, mental state, and risk levels was showcased at a recent law enforcement equipment exhibition in Beijing. Firms presented biometric devices designed to enhance police efficiency and address shortages of frontline officers.

Exhibitors at the international police and anti-terrorism technology expo, which concluded on Saturday, aimed to introduce the latest law enforcement equipment to global police forces. Notably, Indonesia expressed interest in Chinese counterterrorism gear during the event.

Among the featured technologies was a camera developed by Tiandy, a video surveillance supplier. This camera can assess the vital signs of up to six individuals simultaneously, including heart rate, blood pressure, blood oxygen level, and blood flow rate. According to Tiandy, the system achieves over 90% accuracy after about 10 seconds of scanning, displaying results alongside live images, with abnormalities highlighted in yellow or red.

Tiandy suggested the technology is best suited for interrogation waiting areas, where multiple cameras could monitor numerous individuals. The system can track detainees' locations, alert to medical emergencies, and flag irregular policing conduct, such as unattended detainees or interrogations conducted by a single officer, thereby helping to enforce protocols.

The exhibition also highlighted humanoid traffic police robots deployed in Hangzhou, China's tech hub, indicating a broader trend of AI integration in public safety and law enforcement.
