The newly upgraded DM03 4K 2160P Ultra HD Cycling Dash Cam is a professional high-performance intelligent recording device developed specifically for bicycle, electric bike, scooter and motorcycle riders. Designed for outdoor all-weather riding safety, this dash cam integrates ultra-high-definition video recording, industry-leading starlight night vision, IP68 full waterproof protection, professional anti-shake stabilization, intelligent loop recording, high-efficiency graphene heat dissipation and wireless WiFi mobile control into one compact and durable device, bringing riders a more stable, clearer and smarter all-day recording experience. Equipped with an upgraded 800W high-precision HD front image sensor, this device supports genuine 4K 2160P ultra-high-definition single-lens recording. Compared with ordinary 1080P riding cameras on the market, the 4K ultra-clear resolution greatly restores real road textures, accurately captures road signs, license plate details, traffic conditions and surrounding environmental changes. Every recorded frame presents rich layers and true colors, providing clear, effective and legally referable video evidence for daily commuting records, sudden traffic collisions, road disputes and accident responsibility identification, fully protecting your legitimate riding rights and interests. This dash cam is built with advanced starlight night vision technology, which greatly enhances low-light imaging capability. It intelligently adjusts image exposure, automatically suppresses picture noise, optimizes light balance and enhances dark area details. Even in extremely dim environments such as night riding, dusk commuting, tunnel passing and weak street lamp lighting, it can record bright, clean and ultra-identifiable videos without blurring, graininess or overexposure. It perfectly solves the common problem of poor night recording effect of traditional riding cameras and realizes true 24-hour all-weather clear recording. Reaching professional IP68 waterproof and dustproof level, the DM03 cycling recorder has excellent outdoor environmental adaptability. It can effectively resist heavy rain erosion, road water splashes, flying sand, dust accumulation and humid fog weather. It can work stably for a long time in harsh outdoor conditions without water ingress, short circuit or dust blockage. Unlike ordinary IP66 cameras that cannot withstand heavy rain, IP68 high-grade protection allows you to ride normally in rainy and dusty days without frequently disassembling and storing the device, greatly improving the practicability and durability of outdoor riding recording. Adopting optimized mechanical anti-shake buffer structure, the camera can effectively offset and absorb strong jitter and vibration generated by bumpy roads, potholes, speed bumps and rough gravel roads during riding. It thoroughly avoids picture jitter, distortion and blurry recording caused by vehicle vibration, ensuring that every 4K video output is smooth, stable and fluent. In addition, the intelligent loop recording function automatically overwrites the earliest stored invalid footage when the memory card is full, realizing uninterrupted cyclic recording without manual file cleaning, making daily recording more intelligent and worry-free. In terms of power supply adaptation, this dash cam adopts universal 5V USB power supply scheme and is equipped with a free upgraded 5V-100V wide-voltage step-down cable. It supports ultra-wide voltage range adaptation and is compatible with almost all two-wheel vehicles on the market, including ordinary bicycles, electric bicycles, electric scooters and various motorcycles. With safe and stable voltage conversion performance, it supports long-term continuous power supply and recording, no complicated wiring or vehicle modification is required, plug and play, perfectly adapting to daily commuting, night travel and long-distance self-driving travel scenarios. Built-in exclusive independent WiFi hotspot (SSID starts with BD or Hi), the device supports direct mobile phone connection without router or mobile network. Users can download the official Viidure APP through the App Store. After one-click WiFi pairing, you can realize real-time camera preview, historical video playback, picture viewing and one-click file download on your mobile phone anytime and anywhere. You can check accident evidence and share wonderful riding moments on site, eliminating the trouble of disassembling the memory card and connecting to a computer, greatly improving operating convenience. Different from ordinary riding cameras that are prone to high temperature heat accumulation and overheating crash during long-time recording, the DM03 dash cam adopts high-efficiency graphene heat dissipation technology. With ultra-high thermal conductivity, it can quickly export and dissipate the heat generated by long-hour 4K high-load operation, effectively avoiding equipment overheating, recording interruption, freeze and shutdown failure. It greatly improves the overall working stability, continuous recording capacity and service life of the product, achieving higher functional performance than ordinary traditional dash cams. To meet the installation needs of different vehicle structures, the product is equipped with three practical installation brackets for free: handlebar bracket, rearview mirror bracket and front hood patch bracket. Users can freely choose installation positions and methods according to their vehicle appearance and space conditions, with simple installation and no damage to the vehicle body. In addition, we provide a free 64GB high-speed TF card, which supports stable high-speed writing of 4K videos and large-capacity storage. The device can be used out of the box, saving your extra accessory purchase cost and time cost, bringing you a more cost-effective and high-quality riding safety recording experience.
