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.

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.

2. Dash Cam Installation & Technical Features
How does 24-Hour Parking Mode work?
Parking Mode keeps your dash cam monitoring your vehicle while engine power is off. To enable 24/7 parking surveillance, you must install a 3-lead Type-C Hardwire Kit (e.g., AZDOME JYX05) to supply continuous power from your vehicle's fuse box without draining the main car battery.
Why does my dash cam use a supercapacitor instead of a lithium battery?
Supercapacitors are vastly superior for automotive environments. They tolerate extreme hot and cold temperatures, eliminate battery swelling risks, and ensure reliable shutdown performance to save the last recorded video file safely.
What MicroSD card should I use with my 4K or multi-channel dash cam?
High-bitrate 4K and multi-channel cameras require Class 10, U3, V30 speed rating MicroSD cards (up to 256GB/512GB depending on model). We recommend High Endurance memory cards explicitly rated for continuous dash cam loop recording.
3. Apps, Firmware & Connectivity
4. Smart Locks & Home Security (LNDU & ARPHA)
What happens if my smart lock battery dies?
All LNDU smart locks feature low-battery warning alerts. In the event of a completely drained battery, you can unlock your door using the included physical backup keys or connect a power bank via the emergency Micro-USB / Type-C port on the exterior keypad to power up the lock temporarily.
Are ARPHA outdoor cameras waterproof?
Yes, ARPHA wireless outdoor security cameras carry an IP67 weatherproof rating, allowing them to operate reliably under rain, snow, dust, and direct sunlight.
