What is a Mobile NVR?

A mobile NVR, or Network Video Recorder, is a type of device used in vehicle surveillance systems. It is primarily designed to store and manage video data and other information captured by cameras and monitoring devices installed on vehicles. This technology is commonly utilized in locations such as public buses, trucks, small vehicles (taxis), and is also employed by law enforcement agencies and public transportation services.
