Does dash cam automatically delete old footage?

Dash cams have become a popular tool for recording footage of one’s travels on the road. With their affordability and easy installation, they are becoming more and more commonplace in vehicles.

However, many people wonder if dash cams can automatically delete old footage when the memory is full or when a certain amount of time has passed. This article will explore this question in depth, looking at the different types of dash cams and how they store data.

Does Dash Cam Automatically Delete Old Footage

Do dash cam automatically delete old footage?


Yes, dash cams are designed to automatically delete the oldest footage when the SD card becomes full. Dash cams save video files in a loop, meaning that once the SD card becomes full, it will start deleting the oldest file to create space for new recordings.

This feature is essential because it ensures that you always have space on your SD card to capture new events. The length of time before the dash cam starts deleting old files depends on several factors such as the size of your SD card and recording resolution.

For example, if you have a 32GB SD card and record at 1080p quality, you can expect up to 5-6 hours of continuous recording before the dash cam starts overwriting old footage. However, if you are using a smaller capacity memory card or higher-resolution settings like 4K or 2K, then the loop time may be shorter.

Why Is There an Option to Delete Old Footage Automatically?

As technology advances, the use of dash cams has become more prevalent than ever before. They are an essential tool for capturing evidence in case of accidents or other incidents on the road. However, one potential challenge that arises with these cameras is managing their memory card capacity.

If the memory card reaches its maximum capacity, it can stop recording and overwrite old footage, which could be disastrous if you need to access important footage. Fortunately, many dash cams come equipped with an automatic feature that deletes old footage once the memory card reaches a certain threshold.

This option ensures that there is always enough space available for new recordings without constantly monitoring and managing your camera’s storage manually. The reason why this option exists is simple – to make sure that your dash cam continues to function optimally without interruption.

If you want to prevent your files from being automatically deleted, you need to take some steps. The first step is to access the storage settings of your device. This can be done by going into your device’s system settings and finding the storage option.

Once you have accessed the storage settings, there are several things you can do to ensure that your files are not automatically deleted. One option is to change the default setting for how long unused files are kept on your device before they are deleted.

You can also set up automatic backups so that important files are saved in a separate location. In addition to these options, there may be other features available depending on the type of device you have.

For example, some devices allow you to specify which types of files should be protected from deletion or give you greater control over how much storage space is dedicated to different types of content.

Frequently Asked Questions:

Do Dash cams run out of storage?

The answer is no; they should never run out of storage if properly configured. The reason behind this is that most dash cams are designed to automatically overwrite old footage when the memory card reaches its maximum capacity.

So as long as the dash cam has enough storage space available, it will continue to record without interruption. However, it’s important to note that some cheaper models might not have this feature or may require the manual deletion of old recordings. Another factor that affects the amount of storage required by a dash cam is the video resolution and frame rate settings used.

How long does an SD card last in a dash cam?

SD card technology has revolutionised the way we store and transfer data. The latest advancements have made it possible to record up to 40 hours of footage on a single 64 GB SD card, making it an ideal choice for use in dash cams.

This means that you can capture all your driving experiences without worrying about running out of memory space or losing important recordings. Many people wonder how long an SD card lasts in a dash cam.

Well, the lifespan of an SD card depends on various factors such as brand, quality, usage frequency and storage conditions. In most cases, a good quality SD card designed specifically for use with dash cams can last for years before showing any signs of wear and tear.

However, it is important to note that frequent formatting or overwriting of data can significantly reduce the lifespan of your SD card.


Dash cams are a great tool to have in any vehicle, especially in the event of an accident. They can provide real-time recordings to help determine the cause and provide evidence if needed. The best part is that they automatically delete old footage, so there is no need to worry about permanently storing large amounts of data.

This may be a concern for some individuals who want to store their recordings, but the majority of users will benefit from having this feature. Dash cam manufacturers have made it easy for users by providing automatic loop recording that allows you to keep your most recent footage without having to worry about manually deleting old footage.
