8CH Car DVR, 4G Voice Intercom & GPS Tracking, Remote Management

1. Core Functions: More Than Recording—Focused on Safety and Efficiency

1.1 HD Monitoring and Detail Capture

· Starlight night vision: In low-light conditions (e.g., unlit roads at night), starlight-level cameras with IR illumination improve clarity by 50%, making license plates and faces clearly identifiable.

· Wide dynamic range (WDR): Automatically adjusts exposure in backlit or strong-light scenes (oncoming headlights, tunnel entrances), avoiding overexposed highlights and underexposed shadows to reproduce true scenes.

1.2 Intelligent Analysis and Active Alerts

· ADAS driver assistance: Detects lane departure, forward collision, and pedestrian crossing and gives audible/visual alerts 2 seconds in advance to reduce accident rates.

· DSM driver monitoring: Uses the driver-facing camera to detect fatigue (yawning, eyes closed) and distraction (phone use, smoking), provides real-time voice reminders, and logs violations.

· BSD blind spot detection: Identifies pedestrians/vehicles in side/rear blind spots while reversing and triggers a buzzer alarm to minimize scraping risks.

1.3 Data Management and Remote Maintenance

· Local + remote dual management: Set recording parameters, view live video, and search historical clips via device buttons or a management platform (PC/mobile).

· SD card intelligent management: Supports “read-only mode” (prevents accidental deletion), “auto-overwrite” (deletes oldest files when full), and remaining capacity alerts.

2. Hardware and Performance: Optimized for Vehicle Environments

· Multi-channel HD input: Supports 4–8 channels of 1080P cameras (front road, driver position, cargo area, reverse view, etc.) with H.265 compression to balance quality and storage usage.

· Wide-voltage power supply: 9–36 V input (compatible with cars, buses, and special vehicles), supports ignition-controlled on/off (auto-record when vehicle starts, delayed shutdown when turned off).

· Protective design: Metal housing with IP54 dust/water resistance , vibration resistance (compliant with GB/T 28046), and high-temperature tolerance (stable operation at 70°C inside vehicle in summer).

· Network and expansion: Supports 4G/5G/Wi-Fi for remote video viewing and SD card file download; some models have RS485/IO ports for connecting external sensors (fuel consumption, temperature, etc.).
