The system integrates a camera, AI video analysis terminal, lighting system, lifting system, transmission and storage system, energy storage and power supply system, trailer body, and control system into an integrated design.
Cameras, lighting fixtures, lifting mechanisms, battery boxes, and storage hosts are designed with a modular structure.
Pneumatic lifting pole with a height of 10 metres when extended; consists of 7 sections, with 6 sections extended; retracted height of 2.1 metres, maximum outer diameter of 210 mm, minimum inner diameter of 65 mm, made of aluminium alloy; T6 treated, wind resistance rating of 8.
Supports dual 4G wireless transmission, with signal fusion technology for smoother video and higher clarity.
Supports dual TF card storage, with a maximum capacity of 256GB per card, enabling up to 40 days of recording time (expandable with a hard drive storage unit for larger storage capacities).
Whether online or offline, it supports expanded features such as license plate recognition, facial recognition, helmet detection, smoking detection, reflective detection, and mask detection. It provides on-site alerts for non-compliant behaviour, real-time screenshot capture and recording via the remote platform, along with alarm notifications.
Suitable for temporary mobile surveillance and lighting needs, such as border and coastal defence, highways, river environment monitoring, temporary police surveillance, large-scale events, marathons, exhibitions, riots, construction sites, smart construction sites, China National Petroleum Corporation (CNPC), China Petroleum & Chemical Corporation (Sinopec), natural gas sites, blasting sites, municipal construction, railway bridge construction, and fire emergency rescue operations, enabling emergency wireless surveillance.
