Dual lens dash cam manufacturers

Buyers should prioritize Resolution and Sensor Quality; a minimum of 1080P Full HD for both front and rear lenses is essential, though 4K (Front) + 1080P (Rear) is preferred for capturing license plates. Ensure the use of Sony Starvis sensors for superior Night Vision (WDR/HDR) capabilities. Additionally, the Field of View (FOV) should be between 140° and 170° to minimize blind spots without causing excessive fish-eye distortion.

Look for devices that support Loop Recording and have a built-in G-Sensor for automatic emergency file locking during collisions. High-capacity support for Class 10 U3 MicroSD cards up to 256GB is critical for high-resolution dual-channel streams. For extreme climates, choose units with a Supercapacitor instead of a lithium battery to prevent overheating, swelling, and explosion risks.

For the US market, FCC certification is mandatory to ensure no electromagnetic interference with vehicle electronics. For the EU, CE and RoHS certifications are required. If the device includes GPS or Wi-Fi, ensure it meets RED (Radio Equipment Directive) standards. Buyers should also verify E-Mark certification if the product is intended for OE (Original Equipment) integration in Europe.

Features such as Built-in Wi-Fi with App Control allow users to download footage directly to smartphones, which is a major selling point. GPS Tracking for speed and route logging is highly valued for fleet management. Additionally, 24-hour Parking Monitoring (requiring a hardwire kit) and AI-based ADAS (Advanced Driver Assistance Systems) like lane departure warnings provide a competitive edge in the premium segment.

Always request a Pre-shipment Inspection (PSI) by a third-party agency to verify that the image sensor and chipset match the advertised specifications (e.g., verifying a genuine Novatek or MStar/SigmaStar processor). Utilize Made-in-China.com's Secured Trading services to ensure payment is only released upon confirmation of product quality and quantity.

Focus on Long-term Warranty Terms; reputable manufacturers should offer at least a 12 to 24-month replacement warranty. Negotiate for OEM/White-labeling services, such as custom startup logos and packaging, which are often available for MOQs of 500-1000 units. Ask for a tiered pricing structure where the unit price drops by 5-10% as volume increases.

Since dash cams are sensitive electronics, ensure the supplier uses Anti-static packaging and thickened pearl cotton padding. If the units contain small lithium batteries, they must be shipped under UN38.3 regulations for dangerous goods. For bulk orders to the US or Europe, Sea Freight (LCL/FCL) is most cost-effective, but ensure the provider handles Customs Clearance (DDP) to avoid unexpected tariff hurdles.

Conduct business with Audited Suppliers on Made-in-China.com who have verified factory videos and business licenses. To protect your brand, sign a Non-Disclosure Agreement (NDA) before sharing custom UI designs or app requirements. Always use Traceable Payment Methods and avoid direct wire transfers to personal accounts.
