Dash Camera (4K Front + 1080P Rear)

What to Check When Sourcing

Dash cameras are video evidence devices — image quality under adverse conditions (night, glare, rain) is the core value proposition. The sensor and lens specification determines whether the camera captures license plates and details that matter. Our sourcing service helps you identify factories with proven low-light imaging capability, not just paper specifications.

Night vision performance. Test samples in a parking garage and on an unlit road. The f/1.8 lens aperture is the critical spec for low-light performance — f/2.0 collects 40% less light than f/1.8. Request low-light sample video before approving samples, not just daytime footage. Ask the factory to specifically identify the image sensor model on the production BOM — Sony IMX sensors (IMX415, IMX335) are substantially better than generic OmniVision equivalents in this price range.

Capacitor vs. supercapacitor vs. battery. High-temperature environments (parked car in summer) reach 70–80°C. Li-ion batteries degrade rapidly at these temperatures; supercapacitors are more reliable for parking mode operation. For markets with hot climates (Middle East, Southeast Asia, Southern US), specify supercapacitor-based parking buffer instead of battery.

GPS accuracy and track log format. GPS track logging is important for insurance claims. Verify the GPS lock time (<30 seconds from cold start), horizontal accuracy (≤5m), and whether the track log is exportable in standard KML/GPX format.

Loop recording reliability and file integrity. Continuous loop recording writes files to the microSD card constantly. Test what happens when power is cut mid-write: the most recent file should be playable even when interrupted, not corrupted. Corrupted last-file on impact is a common failure mode that makes the dash cam useless for evidence at the moment it matters most.

WDR (Wide Dynamic Range) at sunrise/sunset. The most common real-world complaint about dash cams is blown highlights when driving toward a low sun. Test WDR performance with the camera pointed directly at a bright light source. A genuine hardware WDR sensor handles this; a software-only solution (most budget cameras) still clips highlights and blacks out shadows simultaneously.

Common Issues

MicroSD card compatibility — Dash cam continuous recording is write-intensive. Not all microSD cards support high-endurance continuous write cycles. Specify a branded, high-endurance card (Samsung PRO Endurance, Sandisk Endurance) in your kit, or specify minimum card requirements in the user manual.

Parking mode current draw — Parking mode must draw <100mA from the vehicle battery to avoid draining a standard 60Ah battery overnight. Measure actual parking mode current draw on samples.

Mounting adhesive failure in hot climates — 3M adhesive mounting pads commonly fail at dashboard temperatures above 80°C, causing the unit to fall. For markets with hot summers, specify a dual-mode mount: adhesive plus friction clip, or a suction cup alternative. Our inspection service can verify parking mode current draw, GPS accuracy, and SD card write endurance on pre-production units.
