Dash Cam Storage: How Much Memory Do You Really Need?

Last updated at: Jul 24, 2025

Dash cams have become an essential tool for drivers, providing security, evidence for insurance claims, and even capturing unexpected moments on the road. One of the most common questions is: How much memory do you need for a dash cam? The answer depends on factors like video resolution, recording duration, and the specific features of the camera.

In this guide, we’ll break down everything you need to know about choosing the right storage solution for your dash cam, focusing on the advanced features of Nexar’s connected dash cams.


Understanding Dash Cam Storage with Nexar

Unlike traditional dash cams that rely solely on microSD cards, Nexar dash cams take storage to the next level. With Nexar, the emphasis isn’t just on memory size but on how intelligently and securely your footage is stored and accessed.

Unlimited Cloud Storage with Nexar

One of Nexar's standout features is unlimited cloud storage of critical footage. When an incident occurs – such as an accident, break-in, or any unusual event – Nexar automatically backs up the relevant video clip to the cloud. This ensures that important footage is never overwritten or lost, regardless of how much driving you do.

The Nexar Connect app and the LTE Protection Plan allow you to review your footage from anywhere, anytime, ensuring round-the-clock protection and peace of mind.

Time Lapse Preview: Quick Access to Key Moments

Nexar’s time-lapse preview feature makes it easy to find specific moments, such as accidents or suspicious activity. Instead of sifting through hours of video, you can quickly pinpoint and extract crucial footage, saving you time and hassle.


Choosing Your Dash Cam Memory with Nexar

Pre-Configured Storage Options

When purchasing a Nexar dash cam, you choose the memory size when purchasing your dashboard camera. Nexar cameras come with built-in memory options that are specifically designed to work seamlessly with the device. Unlike other brands, you cannot insert a different microSD card later—this eliminates compatibility issues and ensures optimal performance.

Nexar’s storage configurations are tailored to maximize efficiency and provide cost savings on hardware. Our connected cameras, such as beam2 mini, are backed by unlimited cloud storage for any critical events that occur. This combination provides the best of both worlds: reliable local storage for day-to-day driving and cloud storage for important incidents.


Factors That Influence Storage Needs

1. Video Resolution and Quality

Dash cams record video in different resolutions—from Full HD to 4K. The higher the resolution and frame rate, the clearer your footage will be—but this also means more data gets stored per second.

Here’s a quick look at how much space typical Nexar models use per hour of recording:

Dash Cam Model

Recording Quality

Estimated Storage Use

Beam2 Mini

1080p @ 30 fps (~16 Mbps)

~2 GB/hour → ~32 hours on 64 GB

Beam2

2K QHD @ 30 fps (~28 Mbps)

~4 GB/hour → ~16 hours on 64 GB

Nexar One

4K UHD @ 30 fps (~50 Mbps)

~6.5 GB/hour → ~20 hours on 128 GB

💡 Tip: Actual storage may vary based on lighting conditions, traffic, and scene complexity.

Nexar cameras record in high resolution, ensuring clear and detailed footage. However, thanks to unlimited cloud storage, you don’t need to worry about whether or not you have space for critical events.

2. Recording Duration and Usage

Consider how long you drive daily:

  • Short Commutes or Occasional Use: Standard local storage is sufficient.
  • Daily Commuters and Rideshare Drivers: The unlimited cloud storage ensures that even with extensive daily usage, critical footage is always saved.

3. Event-Based Recording

Nexar dash cams are equipped with G-sensors that detect sudden movements, triggering event-based recording. These critical moments are automatically backed up to the cloud, preventing them from being overwritten.

4. Loop Recording

Nexar dash cams have a feature called loop recording, which means older footage is overwritten by new recordings. However, this doesn’t affect critical footage, as important events are securely stored in the cloud.
