Product Detail

Product composition

OK-PR05-AI mainly integrates high-performance GPU module, embedded deep learning algorithm, integrates IPC access, lifting system, 4G transmission system, storage, management, control and intelligent analysis to achieve helmet + Fireworks detection and other AI empowerment, real-time video for real-time identification and detection of workers' helmets and smoke and flames on the construction site, dangerous behaviors such as not wearing helmets and smoking on the construction site, as well as smoke and flames,The behavior and phenomena of the construction site can be monitored and alerted in real time. The alarm videos and screen shots can be displayed on the client. The audio and speakers can be deployed on the site to give alarm prompts. The remote command center can realize the bullet-screen alarm, which can also be based on the user's needs. Push the alarm information to the relevant management personnel to assist the management personnel in safe production management. Backstage can be called remotely.Easy installation, simple operation and integrated design, flexible body, with dragging tires, easy to arm and move; integrated telescopic bracket for easy fixing; monitoring rod can be lifted and lowered, equipped with high-definition 360° rotating camera; support Wi-Fi/3G/ 4G wireless network signal transmission; comes with a cover-type display for easy local viewing; built-in 1 set of batteries, can last 24H (according to battery size); customized features, support for flow control, temperature and humidity monitoring, dust monitoring and other functions.
