Bus CCTV System

A bus CCTV system is a closed onboard surveillance network that records inside the bus and sometimes records outside. Stores footage locally or optionally uploads footage when connected to a depot or network.

Mobile NVR/DVR

Inside the bus there’s a central recording unit (mobile NVR/DVR)

here’s a Hikvision DS-MP5604N 4ch Mobile NVR for exmaple:

G-sensor (gravity sensor)

or accelerometer measures acceleration and physical forces (shocks, impacts) acting on a device, commonly used in dash cams to automatically lock and protect video footage during accidents

GPS tracking

Records bus route, syncs with video timestamps.
