The STC-8731 supports real-time 4G video transmission, allowing users to remotely view vehicle conditions through the mobile APP. Whether monitoring a single vehicle or an entire fleet, users can access live video streams and playback recordings without being near the vehicle.
The system combines a 2K front camera with a 1080P rear camera, providing comprehensive front and rear coverage. This dual-channel recording solution helps capture more driving evidence and improves visibility during vehicle operation and parking events.
Built-in GPS and Beidou positioning support real-time location tracking, route playback, electronic fencing, and anti-theft monitoring. Vehicle movement history can be reviewed through the APP, making management more efficient for commercial operations.
Important videos and event recordings can be uploaded to the cloud platform automatically. Cloud backup reduces the risk of losing valuable footage due to memory card failure, theft, or accidental damage to the device.
The platform allows up to four users to access the device simultaneously. Fleet managers, supervisors, and vehicle owners can monitor vehicles remotely through authorized accounts, supporting collaborative management.
The STC-8731 is equipped with a Hi3516 Cortex-A7 processor and 1GB memory, delivering stable performance for recording, remote monitoring, and cloud communication. The hardware platform supports smooth video transmission and reliable system operation.
A 1/3-inch CMOS sensor captures high-quality images while maintaining low power consumption. Combined with H.264 video compression technology, the system balances image quality and storage efficiency.
The front camera provides a 125° diagonal viewing angle, helping capture multiple lanes and surrounding traffic conditions. The included rear camera extends monitoring coverage for enhanced vehicle protection.
