Viewing your footage
How to view dash cam footage
There are three ways to get dash cam footage onto a screen you can actually watch it on: take the memory card out and read it with a card reader, connect to the camera's own WiFi through its app, or play it back on the camera's own built in screen. A card reader is the most reliable of the three, because it depends on nothing but a working file system, not an app or a wireless connection.
Method one: card reader (most reliable)
Remove the memory card from the camera and insert it into a card reader connected to a computer or phone, many phones take microSD via a small adapter or a dedicated reader. From there you browse and copy files exactly as you would from any other storage device, with no app, pairing or extra software involved beyond a standard file browser.
Method two: the camera's own WiFi and app
Most current dash cams create their own local WiFi hotspot that a phone connects to directly, and the manufacturer's app then lets you browse, preview and download clips over that link without removing the card.
To be blunt about it: owners of several different dash cam brands report the app is consistently the weakest part of the product, dropped connections, slow transfers, clips that refuse to load. Treat the app as a quick way to check something recorded at all, not the method to rely on if you need a clip off in a hurry.
Method three: the camera's own screen
Some cameras include a small onboard screen for playback, useful for a fast check that something has recorded at all. The screen is generally too small to reliably read fine detail such as a number plate, and not every camera has one: some rely entirely on the app or a card reader instead.
File formats and timestamps
Dash cam footage is commonly saved as MP4, sometimes MOV or AVI depending on the camera, with the date and time burned directly into the video as an on screen overlay. Some cameras also store GPS and speed data in a separate companion file alongside the clip. That timestamp is only as accurate as the camera's own clock, which can lose its setting after the camera loses power for a while, for example if the battery is removed or the car battery is disconnected, so it's worth checking the overlay is actually correct before relying on it.
Why you shouldn't edit a clip you intend to submit as evidence
If footage might go to the police or an insurer, don't trim, re-encode or otherwise edit the file. Work from a copy and leave the original untouched. Editing a video changes the file itself, and an altered file is far easier to challenge as unreliable than one that hasn't been touched at all.
Worth knowing before you hand anything over: footage you submit can be used against you, not only against anyone else in it.
Questions
What is the best way to view dash cam footage?
Removing the memory card and reading it with a card reader is the most reliable method, because it depends only on a working file system rather than an app or a wireless connection staying up.
Why won't my dash cam's app connect?
The app and WiFi link are commonly reported as the weakest part of the product across several dash cam brands: dropped connections, slow transfers and clips that won't load are common complaints. If you need a clip urgently, a card reader avoids the app altogether.
What file format does dash cam footage save as?
Most commonly MP4, sometimes MOV or AVI depending on the camera, with the date and time burned into the video frame itself. Some cameras also save GPS and speed data in a separate file alongside the clip.
Can I trim a video before giving it to police or an insurer?
Best not to. Editing the file, even just trimming it, makes it easier to challenge as unreliable. Keep the original clip untouched and hand over a straight copy of it instead.
Can dash cam footage be used against me instead of the other driver?
Yes. Footage you submit isn't guaranteed to only help your case, it can be used against you too if it shows something you didn't intend it to.
