How to Check the Firmware Version on a Dash Cam
Short answer: Look in the dash cam's Settings or System menu, usually under Device Info, System Information, or About. The firmware version tells you which software your camera runs. Check it before downloading an update, when troubleshooting, and whenever support asks. Write the version down and compare it with the manufacturer's support page.
Start in Settings or System
Most dash cams put the firmware version inside a Settings or System menu. Open the main menu, look for the gear or system icon, and then check a submenu named Device Info, Device Information, System Information, or About.
On button-controlled dash cams, press the Menu button until the Settings group appears, then scroll through the icons. On touchscreen models, open the gear icon and look for an About, Information, or Version entry. If you cannot find it, the quick-start guide or the full manual usually lists the exact path for your model.
Before you update anything, read the basic steps in dash cam firmware update so you understand how the process works.
What the version string tells you
Firmware is the dash cam's system software. The version string identifies the exact build your camera runs. It usually contains a model code, a main version number, and sometimes a build date or a hardware revision letter.
You need that exact string before installing an update, because the file you download has to be newer than the version already installed. If the support page lists a version like V1.2 and your camera shows V1.5, you already have the newer build and do not need to apply that file.
The version string also helps you recognize when a fix is meant for your hardware revision. A camera with an older main board may not be compatible with firmware written for a newer revision, even when the model name looks the same. That is why support teams ask for both the model and the full firmware string.
Why the firmware version matters
Updates are often used to fix startup loops, freezes, memory card compatibility issues, Wi-Fi connection problems, sensor behavior, and parking mode bugs. If a fix targets an older version and your camera already has that fix, the version number tells you that an update may not be necessary.
Keeping firmware current can also affect video recording behavior. A new release might change the way the camera handles file formats, bitrate, exposure, or the way it switches between modes. See dash cam bitrate explained and dash cam file system for background on what those settings do.
Support teams also ask for the firmware version when you report a problem. The version, together with the model name and hardware revision, lets them match the issue to a known fix. If you contact support without that information, the first request will usually be to check the settings menu and report the version.
After you find the version
Write down the full version string, including letters and numbers. Compare it with the version on the manufacturer's support page for your exact model. If a newer version exists, download the firmware file and follow the instructions exactly.
After the update, return to the same menu and confirm the new version appears. If you used a phone app to update the camera, also check the app version: how to update dash cam app explains the difference.
On Wi-Fi dash cams, the companion app often shows the firmware version in the connected device settings. The firmware version is not the same as the app version; the app updates through the phone's app update mechanism, while the camera firmware updates on the camera itself. See dash cam wifi apps for more on app-based controls.
Cloud-connected dash cams may show the firmware version in the companion cloud account as well. dash cam cloud storage explains what cloud features do and do not update.
Troubleshooting with the firmware version
When a dash cam misbehaves, checking the firmware version is one of the first steps. If the version is older than the latest release listed by the manufacturer, an update may resolve the issue.
For example, a camera that keeps overwriting event files or refuses to format a card may be fixed by a newer firmware build. See dash cam event files overwritten and dash cam wont format card for related troubleshooting steps.
If you are already on the latest version and the problem continues, the firmware version plus the exact symptoms help a support agent rule out software causes. You should also check the memory card and the power source, since many problems come from a card that is not supported or a charger that cannot supply enough power. See dash cam microsd storage for card guidance.
How checking firmware fits into buying
If you want the easiest update path, look for a dash cam with Wi-Fi and a companion app. These models often let you check the version and install updates through the phone, without removing the memory card. Start with best Wi-Fi dash cams.
Brand maintenance matters too. A brand that publishes clear firmware release notes with version numbers is easier to keep current. See dash cam firmware updates by brand for what to look for.
Screen size is less important than having a Settings menu that exposes the version. Still, mirror dash cams with large screens can make menu navigation more comfortable if you prefer reading firmware details on the camera. Browse best mirror dash cams if that matters to you.

Questions
Where is the firmware version on a dash cam?
On most models, open the main Menu, then look in Settings or System and choose Device Info, System Information, or About. The firmware version appears as a short string of letters and numbers.
Why should I check the firmware version?
It tells you which software build the camera runs. You need it to decide whether an update applies, to compare it with the manufacturer's support page, and to give a support agent the information they ask for.
Does checking the firmware version change any settings?
No, checking is read-only. It does not start an update, erase recordings, or reset preferences. Updating is a separate step that usually requires downloading a firmware file or using the companion app.
Can I check the firmware version in the phone app?
On Wi-Fi dash cams with a companion app, the connected device settings often show the firmware version. The app version is separate and updates through the phone's app update mechanism.
What if my dash cam does not show a firmware version?
Look in the full manual or on the manufacturer's support page. Some models keep the version in a Service or Maintenance menu. If you still cannot find it, contact support with the model name and hardware revision.
Is the firmware version the same as the GPS database version?
No. Firmware is the camera's system software. GPS speed camera databases, when the camera has one, are separate and may update more often.
Do I need to check the firmware version before every update?
Yes, it is a good habit. The version tells you whether the new file is actually newer than what the camera has. Some manufacturers also require that you install an intermediate version before moving to the latest release, so comparing versions matters.
Can firmware updates change the video resolution options?
They can. A manufacturer may add or remove resolution modes, adjust bitrate levels, or change compression settings in a firmware release. After updating, check the resolution menu to confirm your preferred setting is still available.
