What is a 4 Channel Truck DVR?

Introduction to 4 Channel Truck DVR

A 4-channel truck-mounted mobile digital video recorder (MDVR)is an intelligent monitoring device designed specifically for freight vehicles. Unlike traditional fixed DVRs, it integrates four video signal input interfaces, allowing multiple cameras to connect simultaneously and record the driving environment inside and outside the vehicle in real time.

Key functions include:

①　HD video recording

②　Intelligent alerts

③　Position tracking

④　Data storage

It is widely used in logistics trucks, cold chain vehicles, dump trucks, and other commercial scenarios. Compared with standard dash cams, an MDVR offers:

①　Stronger environmental adaptability (shockproof, dustproof)

②　More flexible storage solutions (hard disk + SD card dual backup)

③　Remote management via 4G/Beidou module

This makes it a core tool in modern fleet management.

Working Principle of 4 Channel Truck DVR

1. Multi-channel video acquisition

①　Four AHD/CVBS interfaces connect cameras covering areas such as the front, cabin, and cargo.

②　Supports 1080P HD resolution.

③　High-end models include infrared night vision for low-light environments.

2. AI intelligent analysis

①　ADAS (lane departure warning)

②　DSM (driver fatigue monitoring)

③　BSD (blind spot detection)

④　Real-time driving behavior analysis, with immediate alerts for risks such as eye closure or lane drifting.

3. Data storage & transmission

①　Internal hard disk (up to 2TB) + SD card dual storage.

②　4G network uploads key events (e.g., sudden braking, speeding) to the cloud.

③　Fleet managers can view videos remotely through a mobile app.

4. Power supply & protection design

①　Supports 12V/24V wide voltage input.

②　Built-in supercapacitor allows recording to continue for 3 seconds after power loss.

③　IP54 dust and water resistance.

④　Anti-shock design protects the hard disk from vibration damage.

Functions of 4 Channel Truck DVR

1. Safe Driving Monitoring

①　ADAS warnings: forward collision, lane departure

②　DSM monitoring: detects smoking, phone use, drowsiness

③　Blind spot monitoring: right-side blind spot alarms during lane changes

2. Compliance Management

①　Geofencing: route setting with automatic deviation alerts

②　Driving time statistics: ensures compliance with safety regulations

3. Accident Evidence Collection

①　Locks video 10 minutes before and after accidents

②　Video encryption with hash values to prevent tampering

4. Fleet Operation Optimization

①　Real-time fuel consumption monitoring (with fuel sensor)

②　Vehicle health diagnostics (CAN bus data analysis)

How to Choose a 4 Channel Truck DVR

When making a purchase, enterprises should compare:

1. Chip performance: Industrial-grade quad-core processor with H.265+/H.264 dual codec is superior to standard CPUs with only H.264.

2. Storage solutions: Dual storage (HDD + SD card) with power-off protection is safer than single SD card storage.

3. Compatibility: Systems supporting EU/China protocols fit 90% of commercial vehicles, while proprietary protocols limit flexibility.

4. Expandability: More GPIO interfaces (up to 8) support sensors such as fuel and temperature, while low-end models may offer only 4 or fewer.

5. After-sales service: Global GPS + Beidou dual-mode positioning and a 3-year warranty are better than basic 1-year coverage.

Recommendation: Prioritize internationally certified brands (ISO14001, IATF16949), as they ensure stability under extreme conditions and stronger electromagnetic compatibility.

Recommended Model: YUWEI F4

The YUWEI F4is a flagship product, widely chosen by logistics companies due to:

1. High-end configuration: Industrial-grade high-speed processor, integrated 4G transmission, WIFI, DVR, and BDS/GPS dual-mode positioning.

2. Smart warning system: ADAS + DSM + BSD + rear-view monitoring, reducing human-error accidents by up to 90%.

3. Data security: Encrypted storage with both local and Alibaba Cloud backups.

4. Cost efficiency: 30% lower power consumption compared to similar products, saving over ¥10,000 annually in maintenance.

Installation Guide for 4 Channel Truck DVR

1. Power connection

①　Connect ACC permanent power and control line.

②　Ensures continuous recording for 1 hour after shutdown (vehicle battery ≥60Ah).

2. Camera deployment

①　Front: windshield-mounted, ~1.2m above ground.

②　Cargo cabin: wide-angle lenses covering all four corners.

③　Rear: mounted above tailgate, monitoring loading/unloading.

3. Software configuration

①　Use YUWEI VMS platform to set geofencing (accuracy ≤5m).

②　Bind driver accounts for behavior analysis.

Important Note: Magnetic mounts are prone to vibration-related detachment. Use 3M adhesive plus screwsfor secure fixing.

Choosing a 4 channel truck DVRwith AI algorithms, compliance certifications, and flexible expandability (e.g., YUWEI Vehicles CCTV F4) not only strengthens fleet safety management but also empowers data-driven cost reduction and operational efficiency.
