Factors Affecting Dashcam Recording Time
One of the most commonly asked questions about dash cameras is how long they can record for before they start overwriting previous footage. The answer depends on several factors, including the storage capacity of the dash camera and the video resolution and quality settings that you have chosen.
When it comes to storage capacity, dash cameras can typically range from a few gigabytes to several terabytes. Most dash cameras use SD cards for storage, with the most common capacities being 32GB, 64GB, and 128GB. The more storage capacity the camera has, the longer it can record before overwriting old footage.
Video resolution and quality settings are also important factors in determining the recording time of a dash camera. Higher video resolutions and frame rates require more storage space. As a result, if you choose to record in higher quality settings, you will have less recording time available.
For example, if the dash camera is set to record at a bitrate of 10 Mbps, the recording time can be estimated by dividing the storage capacity by the bitrate. If the dash camera has a 64GB SD card, the recording time would be approximately 8 hours. However, if you choose a lower quality setting with a bitrate of 5 Mbps, you could potentially double the recording time to around 16 hours. On the other hand, if you select a higher quality setting with a bitrate of 20 Mbps, the recording time would be reduced to around 4 hours.
It’s important to note that these are rough estimates and that actual recording times may vary depending on other factors such as the use of any additional features or functionality, the temperature in which the camera operates, and any compression algorithms that the camera may use.
Loop Recording System
Most dash cameras use a loop recording system, which means that when the storage is full, the camera will automatically start overwriting the oldest footage. This ensures that you always have the most recent recordings available, without having to manually delete old footage.
The loop recording system works by dividing the available storage space into segments, known as “loops.” Each loop has a fixed length, typically ranging from a few minutes to a few hours, depending on the dash camera’s settings. As the camera continues to record, the oldest loops are automatically overwritten by new ones, ensuring that the camera always has enough free space to store the latest footage.
The length of each loop can be adjusted in the dash camera’s settings menu. Longer loops will allow the camera to store more footage before overwriting, but may result in longer gaps between recordings as the camera saves the current loop and begins a new one. Shorter loops will create smaller gaps between recordings but may result in more frequent overwriting of old footage.
Storage Capacity of Dash Cameras
The storage capacity of dash cameras can range from a few gigabytes to several terabytes. Dash cameras typically use SD cards for storage, with the most common capacities being 32GB, 64GB, and 128GB.
The amount of footage that a dash camera can store depends on the storage capacity of the camera and the video quality settings that you have chosen. Higher video resolutions and frame rates require more storage space, so if you choose to record in higher quality settings, you will have less recording time available.
The storage capacity of the SD card is fixed, so no matter what video quality settings you choose, the camera can only store a maximum of the capacity of the SD card. However, the video bitrate will vary depending on the video quality settings. Higher bitrates result in better video quality but also require more storage space.

Estimating Recording Time
To estimate how long a dash camera can record before overwriting, you need to consider both the storage capacity and the video quality settings. Higher video resolutions and frame rates require more storage space, so if you choose to record in higher quality settings, you will have less recording time available.
As an example, let’s consider a dash camera with a 64GB SD card and a video resolution of 1080p Full HD. The storage capacity of the SD card is fixed, so no matter what video quality settings you choose, the camera can only store a maximum of 64GB worth of footage. However, the video bitrate will vary depending on the video quality settings. Higher bitrates result in better video quality but also require more storage space.
If the dash camera is set to record at a bitrate of 10 Mbps, the recording time can be estimated by dividing the storage capacity by the bitrate. In this case, 64GB divided by 10 Mbps equals approximately 8 hours of recording time.
However, most dash cameras offer different video quality settings, typically ranging from low to high. The lower quality settings will have lower bitrates and therefore allow for longer recording times, while the higher quality settings will have higher bitrates and shorter recording times.
For example, if the dash camera offers multiple video quality settings and you choose a lower setting with a bitrate of 5 Mbps, you could potentially double the recording time to around 16 hours. On the other hand, if you select a higher quality setting with a bitrate of 20 Mbps, the recording time would be reduced to around 4 hours.
It’s important to note that these are rough estimates and that actual recording times may vary depending on other factors such as the use of any additional features or functionality, the temperature in which the camera operates, and any compression algorithms that the camera may use.
Additionally, some dash cameras offer features such as motion detection or parking mode, which can affect the recording time. Motion detection allows the camera to start recording when it detects any movement in front of the vehicle, while parking mode enables the camera to continue recording even when the vehicle is parked and the engine is turned off. These features may shorten the overall recording time as the camera may be continuously recording, even during periods of inactivity.

Impact of Video Quality Settings
However, most dash cameras offer different video quality settings, typically ranging from low to high. The lower quality settings will have lower bitrates and therefore allow for longer recording times, while the higher quality settings will have higher bitrates and shorter recording times.
| Video Quality | Bitrate (Mbps) | Recording Time on 64GB SD Card |
|---|---|---|
| Low | 5 | Approximately 16 hours |
| Medium | 10 | Approximately 8 hours |
| High | 20 | Approximately 4 hours |
As you can see from the table above, lower quality settings can significantly increase recording time, while higher quality settings can significantly reduce it. It’s important to choose the video quality setting that meets your needs and provides the appropriate balance between video quality and recording time.
In addition to video quality settings, other factors can also affect the recording time of a dash camera, such as additional features or functionality, temperature, and compression algorithms. It’s important to consider all of these factors when estimating how long a dash camera can record for before overwriting old footage.
Other Factors Affecting Recording Time
It’s important to note that these are rough estimates and that actual recording times may vary depending on other factors such as the use of any additional features or functionality, the temperature in which the camera operates, and any compression algorithms that the camera may use.
Additional features or functionality, such as Wi-Fi connectivity or GPS tracking, may also impact the overall recording time of a dash camera. These features typically require additional processing power and may increase the camera’s power consumption, resulting in shorter recording times.
The temperature in which the camera operates can also affect its recording time. Extreme temperatures, either hot or cold, can cause the camera components to expand or contract, resulting in potential damage to the camera or SD card. Additionally, a hot environment may cause the camera to automatically shut down to prevent overheating, resulting in lost recording time.
Compression algorithms can also impact the recording time of a dash camera. These algorithms are used to reduce the size of video files, and some algorithms may be more efficient than others. Cameras that use more advanced compression algorithms may be able to store more footage in the same amount of storage space, resulting in longer recording times.
Impact of Additional Features
Additionally, some dash cameras offer features such as motion detection or parking mode, which can significantly impact the overall recording time. For instance, motion detection allows the camera to detect any movement in front of the vehicle and instantly start recording. Parking mode, on the other hand, enables the camera to continue recording even when the car is parked and the engine is turned off. These features not only consume storage space but also require the camera to remain in an active mode continuously, even if there’s no recorded event.
As a result, such features may shorten the overall recording time as the camera may be continuously recording, even during periods of inactivity. This may cause the SD card to fill up faster and overwrite previous footage, especially if you have set the camera to record at high video quality settings, which require more storage space per unit time.
Conclusion
In conclusion, the actual recording time of a dash camera depends on several factors including the storage capacity of the camera, the video resolution and quality settings, and any additional features or functionality that the camera may offer. By carefully considering these factors, you can estimate how long the camera can record before it starts overwriting old footage. Factors such as the use of motion detection or parking mode may shorten the recording time, while using lower video quality settings can extend the recording time. It’s important to note that these are rough estimates, and actual recording times may vary depending on other factors such as temperature and compression algorithms. Ultimately, it’s up to you to decide the video quality and recording time that suits your needs and preferences.
