In today's complex driving environment, comprehensive vehicle monitoring has transformed from a luxury to a necessity. The LAMTTO 4-Channel Dash Cam delivers true 360° coverage through its innovative four-camera design, providing unprecedented security for drivers. After two weeks of comprehensive testing, we've gained deep insights into this device's capabilities, performance, and user experience.

Revolutionary Quad-Camera Design

The LAMTTO dash cam's core advantage lies in its comprehensive coverage:

Front 1080P Camera

Records the road ahead in HD with a 140° wide-angle lens, capturing license plates and critical details across multiple lanes.

Rear 1080P Camera

Monitors the area behind your vehicle, perfect for documenting rear-end collisions and providing assistance while reversing.

Dual Interior Cameras

Simultaneous recording from both sides of the cabin, specifically designed for rideshare drivers and family vehicles.

All four cameras operate simultaneously at 1080P resolution. With efficient compression technology, a 64GB memory card can store approximately 15 hours of driving footage. The device uses seamless loop recording, automatically overwriting the oldest files to ensure critical moments are never missed.

Infrared Night Vision: Professional Low-Light Monitoring

LAMTTO's interior cameras feature professional-grade infrared night vision technology. Each camera includes 8 IR LEDs and an F2.0 aperture lens, ensuring clear footage even in complete darkness.

Day Mode (Recommended)


Natural color reproduction, clear image

Night Mode


Black & white footage with rich IR detail

Daytime IR Enabled (Not Recommended)


Distorted colors, overexposed image

Critical Usage Tip: Daytime IR Settings

Based on our testing and user feedback, you must set the IR mode to "Auto" or "Off" during daytime. Forcing IR to stay on during daylight causes:

  • Severe color distortion with abnormal color shifts
  • Overexposed images with lost details in bright conditions
  • Lens flare and glare from IR LED reflection

The device defaults to "Auto" mode, which we strongly recommend maintaining for optimal results. Manual IR activation should only be used in extremely low-light environments.

During nighttime testing, the IR system performed exceptionally well, capturing facial features and movements clearly even in total darkness, with an effective range of up to 3 meters - more than sufficient for in-cabin monitoring.

Smart Parking Surveillance & Dual Power System

LAMTTO solves the biggest pain point of most dash cams - parking surveillance. Through an innovative dual-power design, users can choose flexibly based on their needs:

Cigarette Lighter Power (Basic Mode)

Use the included car charger plugged into your cigarette lighter. Automatically powers off when the vehicle is turned off, suitable for users who don't need parking surveillance.

Hardwired Connection (Professional Mode)

Use the included specialized cables to connect to your vehicle's fuse box, enabling 24/7 monitoring. Automatically enters low-power parking mode when the engine is off.

In parking surveillance mode, the device uses its built-in G-sensor to detect vehicle impact or vibration, automatically locking and saving 15-second video clips before and after the event. This feature is particularly valuable in high-risk areas like parking lots and roadside spaces, effectively preventing hit-and-runs, vandalism, and insurance fraud.

5G WiFi Connectivity & Smart Management

LAMTTO's wireless connection system is both powerful and intelligent, providing high-speed data transfer through 5G WiFi:

1

Enable WiFi on Device

Manually activate WiFi on the dash cam

2

Connect Your Phone

Connect to the dash cam's WiFi network through phone settings

3

App Operations

View, download, or share footage through the official app

4

Automatic Disconnect

WiFi disconnects automatically when exiting the app

WiFi Connection Mechanism Explained

LAMTTO uses a unique smart WiFi management system: When you exit the app on your phone, the system automatically disconnects the WiFi to conserve phone resources. After a period (approximately 5 minutes), the dash cam's WiFi function also automatically turns off.

This means you'll need to manually re-enable WiFi on the dash cam for your next connection. While this requires an extra step, it offers two significant advantages:

  • Prevents unnecessary battery drain from continuous WiFi operation
  • Avoids potential performance issues from persistent background connections

User feedback indicates that once this mechanism is understood, most users find it a reasonable design trade-off for improved device efficiency.

The app interface is clean and intuitive, supporting simultaneous preview from all four cameras and featuring one-touch download for emergency recordings. It runs smoothly on both iOS and Android devices with no compatibility issues.

For vehicle owners needing complete documentation of their surroundings and cabin (especially rideshare drivers, commercial operators, and families), this device provides a comprehensive security solution.

Usage tip: Always keep IR mode on "Auto" during daytime, and understand that WiFi connections require manual re-enabling. Once you master these features, you'll enjoy unparalleled vehicle security.
