AZDOME S40 (M660) 4-Channel 4K Dash Cam with 5G WiFi & GPS

Product Overview

The AZDOME S40 (M660) is a high-density, quad-channel vehicle surveillance system engineered for comprehensive 360-degree vehicle perimeter monitoring. By capturing simultaneous, synchronized video streams across four discrete channels (Front, Rear, Left, and Right), the S40 establishes an uninterrupted digital recording loop of the road, lateral vehicle perimeters, and internal passenger cabin to provide total liability protection for personal vehicles, rideshare operators, and commercial fleets.

Technical Specifications

Core Features & Hardware Analysis

True 360-Degree Quad-Channel Recording

The S40 (M660) is powered by a high-efficiency processor designed to handle multi-stream, high-bitrate video inputs. The system records in 4K resolution at the front to capture critical details like distant license plates, while utilizing three dedicated 1080P HD cameras to monitor the left flank, right flank, and rear exterior perimeter simultaneously, leaving zero visual blind spots.

940nm Invisible Infrared Night Vision

The side-facing and interior-facing optics utilize professional 940nm wavelength Infrared (IR) LEDs coupled with Wide Dynamic Range (WDR) exposure balance. Operating beyond the spectrum of visible light, the 940nm IR system captures clear grayscale footage in pitch-black cabin conditions without emitting any distracting red glow that could impair driver visibility at night.

High-Speed Dual-Band 5G WiFi & GPS

An integrated 5GHz / 2.4GHz WiFi module enables high-speed local wireless data transfers to the AZDOME smartphone app, allowing users to retrieve, download, or lock footage on-scene. The integrated GPS bracket embeds exact travel coordinates, routes, and real-time vehicular speed metrics directly into the video file's metadata for legal and insurance purposes.

Extreme-Temperature Supercapacitor Design

To ensure reliable operation in harsh environments, the S40 (M660) replaces traditional lithium-ion batteries with a high-endurance supercapacitor power supply. This design prevents battery degradation, swelling, or heat-induced thermal runaways, allowing the system to operate safely in temperature extremes from -4°F to 158°F (-20°C to 70°C).

Advanced Security & Surveillance Modes

• 24-Hour Intelligent Parking Mode: When wired to an official AZDOME Type-C hardwire kit (sold separately), the camera acts as a stationary surveillance node. Drivers can select between Collision Detection (G-sensor impact trigger), Motion Detection, or Time-Lapse Recording (at 1 frame per second to optimize storage capacity).

• Up to 512GB High-Endurance Storage: Built to support high-capacity write cycles, the S40 supports up to 512GB MicroSD cards. This expanded limit is essential for managing the high data write-speeds required by simultaneous 4-channel recording.

• Seamless Loop Recording: Once your external memory card reaches its maximum storage capacity, the camera automatically overwrites the oldest, unlocked files to ensure uninterrupted capture.

Target Applications

• Rideshare, TNC, & Fleet Drivers (Uber, Lyft, Taxis): Continuous lateral and cabin monitoring protects drivers against false claims, passenger disputes, and side-swipe incidents.

• Commercial Cargo & Fleet Logistics: Provides secondary tracking of vehicle entry points and lateral cargo perimeters to protect assets and improve fleet safety compliance.

• SUVs, Vans, & Family Commuters: Provides multi-angle video evidence to simplify insurance claims in multi-vehicle collisions or parking lot incidents.

Frequently Asked Questions

Q1: Does the AZDOME S40 (M660) record all 4 channels in 4K resolution simultaneously?

A: No. To balance processing power, heat dissipation, and file storage sizes, the system records in 4K UHD resolution for the front camera and 1080P Full HD resolution for the Left, Right, and Rear channels during active 4-channel recording.

Q2: Why is a 512GB SD card recommended for the AZDOME S40?

A: Because the S40 records four high-definition video streams at the exact same time, it processes significantly more data per minute than standard single or dual dash cams. A high-capacity, high-endurance 512GB U3 MicroSD card is highly recommended to prevent the camera from frequently overwriting files.

Q3: What occurs when the vehicle battery voltage drops during 24H Parking Mode?

A: When using the recommended AZDOME 3-wire Type-C hardwire kit, the smart cable monitors your vehicle’s battery voltage. If the battery falls below a safe operating threshold (such as 11.8V), the hardwire kit automatically cuts power to the dash cam to prevent your starter battery from draining.

Frequently Asked Questions

1. Does this dash cam work with iPhone and Android?

Yes, all AZDOME dash cams with WiFi connect easily to both iOS and Android devices via the app. You can view, download, and share videos instantly.

2. Do I need WiFi or internet to use the dash cam?

No. The dash cam records automatically without internet. WiFi is only needed if you want to connect your phone to view or download footage.

3. Does it record when the car is parked?

Yes, with parking mode enabled, the dash cam can monitor your car 24/7. It detects motion or impacts and records automatically.
Note: A hardwire kit may be required for continuous parking monitoring.

4. How long can the dash cam record?

Recording time depends on the memory card size. For example:

• 64GB = several hours of footage

• 128GB–256GB = extended recording time

Loop recording ensures old footage is automatically overwritten when storage is full.

5. Is a memory card included?

Some models include a memory card (e.g., 64GB or 128GB). Please check the product details. For best performance, we recommend using a high-speed microSD card.

6. Will it record at night?

Yes, AZDOME dash cams feature advanced night vision and HDR/WDR technology to capture clear footage even in low-light conditions.

7. Is installation difficult?

No, installation is simple and takes just a few minutes. Most dash cams mount to your windshield or rearview mirror and plug into your car’s power outlet.

8. What happens if there is an accident?

The built-in G-sensor automatically detects sudden impacts and locks the video to prevent it from being overwritten—ensuring important evidence is محفوظ.

9. Can I view footage on the dash cam screen?

Yes, models with a screen allow real-time viewing and playback directly on the device. You can also access videos via the mobile app.

10. Does it support voice control?

Yes, selected models support voice commands like:

• “Lock Video”

• “Take Photo”

• “Turn on WiFi”

This allows hands-free control while driving.
