Buying a dashcam seems straightforward, until you get lost in specifications like resolution, viewing angle, and storage types. The wrong choice can lead to unusable footage or a device that fails after just a few months. This guide helps you make an informed decision based on facts and specifications, ensuring you invest in a dashcam that genuinely adds to your safety and peace of mind.
Before we look at specific models, it's important to understand the core features. These parameters determine the performance and reliability of your dashcam.
The resolution determines the clarity of the image. The higher the resolution, the more likely it is that details like license plates will be readable.
In addition to resolution, HDR (High Dynamic Range) or WDR (Wide Dynamic Range) is crucial. These technologies balance the light in high-contrast scenes, such as when entering or exiting a tunnel or facing oncoming traffic with bright headlights.
A standard dashcam only records the road ahead. For complete coverage, a dual-channel system—a front and rear dashcam—is a better option. This type of system simultaneously records what's happening in front of and behind the car, which can be essential in rear-end collisions.
The way footage is stored is a key factor for reliability.
Modern dashcams offer more than just recording.
Based on the criteria above, we have selected two models from 70mai that cater to different needs and use cases.
Why We Chose It: The M500 focuses on ease of use and reliability. The combination of a high resolution (higher than QHD) and built-in eMMC storage makes it an 'install-and-forget' solution. You don't have to worry about the compatibility or lifespan of a separate memory card.
Pros:
Who is it for? Drivers looking for a high-quality, reliable front-facing camera without the hassle of separate memory cards. Ideal for daily commuters who want solid evidence with minimal setup and maintenance.
Why We Chose It: The A810-2 is engineered for maximum image quality and complete coverage. With Sony STARVIS 2 sensors for both the front and rear cameras and true 4K resolution at the front, this system captures details in the most challenging light conditions. According to German test authorities Autobild.de and Computerbild.de, this model received a "Good" rating in 2024.
Pros:
Who is it for? The demanding user, tech enthusiast, or professional who wants the highest possible image quality and full 360-degree coverage. Perfect for those who want to maximally secure their vehicle, both while driving and when parked.
Models like the 70mai A810-2 require an external microSD card. Your dashcam's performance is directly dependent on the quality of this card. Standard cards are not built for the continuous recording cycle and can lead to corrupted files or recording errors, precisely when you need the footage most. Therefore, always invest in a 'High Endurance' memory card specifically designed for this purpose.

1. Are dashcams legal? Yes, using a dashcam is legal in most countries. You are allowed to record for personal use, for example, as evidence after an accident. However, publishing footage where individuals or license plates are identifiable is subject to strict privacy regulations (like GDPR). Be cautious with this.
2. How does parking mode on a dashcam work? Parking mode activates as soon as you turn off the car. The dashcam enters a standby mode and automatically starts recording when its built-in G-sensor detects an impact (like a collision) or motion. For this feature, the dashcam needs a continuous power supply, which is usually provided by a 'hardwire kit' connected directly to the car's battery.
3. What's the difference between 4K and 1944P? 4K (3840x2160 pixels) is the highest resolution and offers the most detail. 1944P (2592x1944 pixels) is a resolution that sits between QHD (1440p) and 4K. While 4K is technically superior, 1944P already provides a significantly sharper and more detailed image than standard 1080p Full HD, which is more than sufficient for many situations.
