Overview and Highlights of the 70mai Dash Cam Pro Plus+ A500S
The 70mai Dash Cam Pro Plus+ A500S is designed to deliver a clear and reliable recording experience. With its compact design and full suite of smart features for its 2021 launch era, the key highlight of this model is the use of the Sony IMX335 sensor, renowned for its low-light image quality, alongside the ability to record video at 2.7K resolution. At the time, this was considered a high standard, providing sufficient detail for road safety purposes.
Specifications and Real-world Functionality (2021 Model)
Video Recording Quality
Sensor: Equipped with the high-performance Sony IMX335 sensor, delivering excellent image resolution and detail.
Resolution: Records video at 2.7K resolution (2592×1944 pixels) at 30 frames per second, providing a significantly higher clarity than Full HD—perfect for capturing license plates and other key details.
Aperture: A wide F1.8 aperture lens allows more light entry, resulting in great recording performance at night or in low-light conditions.
Field of View: A 140-degree wide-angle view covers multiple lanes, reducing blind spots in recordings.
Image Technology: Supports WDR (Wide Dynamic Range) and 3D DNR (Dynamic Noise Reduction) technologies, which help balance exposure for clear video even in high-contrast lighting situations, such as driving against the sun or inside tunnels.
Video Compression: Utilizes the H.265 codec for superior compression efficiency, keeping video files smaller while preserving quality, allowing for longer recording times on the same MicroSD card capacity.
Advanced Driver-Assistance Systems (ADAS)
One of the standout features of the A500S is its ADAS (Advanced Driver-Assistance Systems), which enhances driving safety:
Lane Departure Warning (LDW): Detects lane markings and alerts the driver if the vehicle is unintentionally drifting out of its lane, helping prevent accidents caused by fatigue or distraction.
Forward Collision Warning (FCW): Measures the distance to the vehicle ahead and alerts the driver if the car gets too close or approaches at a speed likely to cause a collision, giving the driver more time to react and avoid an accident.
Smart Parking Surveillance Mode
For security when parked, the A500S features a smart parking surveillance mode that utilizes a built-in G-sensor to detect impacts or unusual vibrations. When an event is detected, the camera automatically powers on and records the incident, serving as valuable evidence in the event of any mishaps while parked. However, to use this mode 24/7, installing an optional Hardwire Kit is required to draw power directly from the car battery.
Connectivity and Built-in GPS
Built-in GPS: The A500S comes with integrated GPS that accurately logs speed, coordinates, and driving route timestamps, which is highly useful for checking incidents or verifying travel routes.
Wi-Fi Module: Features built-in Wi-Fi, allowing users to easily connect the camera to their smartphone via the 70mai application. You can view live footage, download recorded videos, or adjust camera settings directly from your mobile phone.
Display Screen and Controls
The camera features a 2-inch IPS screen that delivers clear visuals, enabling settings configuration, live viewing, or reviewing recorded footage directly on the device, accompanied by user-friendly control buttons.
Processor and Memory
Processor: Powered by the HiSilicon Hi3556 V200 chip, which offers great performance in managing high-resolution video and processing ADAS functions.
MicroSD Card Support: Supports MicroSD cards up to 128GB (Class 10 or higher), which is sufficient for hours of 2.7K video recording.
