Buying a Dashcam: Key Criteria and Suitable Models for Your Vehicle

A dashcam can document journeys, capture minor parking collisions and provide important video footage in unclear traffic situations. However, not every model is equally suitable for drivers, commuters, families, taxi operators and private-hire providers. It is not just high resolution that matters, but also memory management, power supply, installation and how the dashcam performs in everyday use.

Common Dashcam Buying Pitfalls

1. High resolution without enough storage

A 4K dashcam creates significantly larger video files than a 2K dashcam. Using an unsuitable or too slow dashcam memory card can result in recording interruptions, corrupted files or a short recording time. Before buying, check the following:

  • Maximum supported storage capacity
  • Minimum standard, such as Class 10, and preferably U3
  • Memory card brands recommended by the manufacturer
  • Whether formatting is required via the camera or app

For example, a 128-GB card will not automatically be compatible with every vehicle camera. Compatibility specified for the particular model is what matters.

2. Parking surveillance without the right power supply

The term dashcam with parking surveillance does not always mean that the function is ready to use straight away. Several models require a separate hardwire kit. This connects the car camera directly to the vehicle’s electrical system and, depending on the system, enables time-lapse recording, impact detection or motion detection.

Before installation, check:

  • Whether a hardwire kit is included
  • Whether the connection is suitable for your vehicle
  • Whether low-voltage protection is available
  • Whether the installation needs to be carried out professionally

The LNDU V100 and various DDPAI models require a separately available hardwire kit for 24-hour parking mode.

3. Night vision is advertised using inconsistent terminology

Depending on the model, “night vision” can refer to different technical methods. Look for objectively described specifications such as aperture, sensor, HDR support and recording mode. A wider viewing angle can capture more of the surroundings, but at the same resolution it results in less detail in the image.

The camera’s position also matters. Mounting it discreetly behind the rear-view mirror may obstruct the driver’s view less than positioning a large device in the middle of the windscreen.

Parameters to Check Before Buying

Image quality and camera channels

For most journeys, a front camera with 2K resolution is sufficient, provided that the lens is clean and correctly aligned. If you also want to document events behind the vehicle, you will need a front and rear dashcam. A dashcam with a rear camera does, however, require more installation work, as a cable must be routed through the interior to the rear of the vehicle.

With 4K models, you should also check whether 4K is actually available on the front camera and what resolution the rear camera uses. With dual- or three-channel systems, the maximum resolution is often distributed across the individual cameras.

Storage, loop recording and G-sensor

Loop recording overwrites older, unprotected files once the memory card is full. This is convenient for everyday use, but it does not replace regularly backing up important videos.

A G-sensor detects sudden movements or impacts and can lock the relevant file to prevent it from being overwritten. Its sensitivity should be adjustable, as cobbled roads or a hard speed bump can also trigger the locking function.

Wi-Fi, GPS and app functions

A dashcam with Wi-Fi usually lets you connect to a smartphone without removing the memory card. Depending on the app, you can view, download and manage recordings. Wi-Fi does not, however, automatically provide an internet connection or cloud service.

A dashcam with GPS can record the route, speed, time and coordinates in the footage or in the app. Check whether GPS is integrated or provided via a separate mount.

Sensors such as Sony STARVIS 2 are used in various models to record in difficult lighting conditions. Actual image quality also depends on the lens, HDR processing, compression, installation and lighting.

Legal and Practical Advice on Using a Dashcam

In Germany, dashcam footage should be used in compliance with data protection regulations and, wherever possible, in response to a specific incident. Continuously recording or sharing footage of identifiable people and number plates without restriction can cause problems. The camera must also not obstruct the driver’s field of vision or interfere with the operation of the vehicle.

Before your first journey, we recommend the following setup:

  1. Align the camera behind the rear-view mirror and route the cable securely.
  2. Check the date and time.
  3. Set loop recording and the G-sensor appropriately.
  4. Format the memory card in the camera.
  5. Carry out a short test in daylight and darkness.
  6. Transfer important files to another device promptly.

Frequently Asked Questions About Dashcams

Is a dashcam legal in Germany?

Using one is generally permitted, but you must comply with data protection requirements. Continuous, indiscriminate recording of public roads and surrounding areas can be problematic. Use protected clips only in connection with a specific incident wherever possible, and check the applicable legal framework before sharing any footage.

How long does a dashcam last?

Its lifespan depends on temperature, power supply, memory card quality and daily recording time. Models with a supercapacitor are designed to shut down safely and handle brief power interruptions. A high-quality, compatible MicroSD card should be checked regularly and replaced if errors occur.

Which memory card does a dashcam need?

Follow the manufacturer’s specifications. For 2K and 4K recording, a MicroSD card Class 10 or U3 is often recommended. The capacity must be compatible with the camera. A 70mai 128-GB card or a DDPAI memory card should only be used with models expressly listed as compatible.
