Detailed Description:

The SDVR104 Mobile SD Card DVR System is a versatile, high-definition video recording solution designed for mobile applications in vehicles such as buses, trucks, and cars. With four 1080P channels, it captures clear audio and video in real-time and stores it on a removable SD card. Using H.264 and H.265 compression, this DVR optimizes storage without compromising quality. The system’s embedded firmware allows for seamless configuration and playback, ensuring ease of use for operators.

Equipped with GPS, Wi-Fi, and 4G connectivity, the SDVR104 allows real-time tracking of vehicle speed and location, while remote monitoring is accessible via mobile networks or Wi-Fi. Advanced power management features include wide voltage support (8V-32V), ignition-based control, and a power-off delay function. The system automatically enters sleep mode to conserve power, making it ideal for long-haul and public transportation applications.

The SDVR104 supports multiple recording modes: continuous, schedule-based, alarm-triggered, and motion detection. Built-in sensors monitor vehicle status (left/right turn, reverse), triggering full-screen displays for enhanced driver awareness. The lockable security enclosure ensures all footage remains safe, making this DVR system a secure, reliable choice for fleet monitoring and surveillance.
