Action Cameras
Browse used action cameras for sale from riders across the UK. These are waterproof, fixed-lens bodies shooting from 1080p up to 4K or 5.3K, running roughly 60 to 120 minutes on a battery and mounting to a bar, helmet or chest harness. Bought by mountain bikers filming descents and by commuters who want a record of the traffic behind them.
Which action camera resolution do I need?
1080p at 60fps is enough for anything watched on a phone, and it fills a card and a battery far more slowly. 4K earns its place if you crop or stabilise heavily in editing, and 2.7K at 60fps is the sensible middle for bar-mounted footage. High resolutions are also what makes a small body run hot and stop, so a used camera reported as overheating may simply have been set beyond what it can sustain.
Action camera or 360 camera?
A standard body records what it is pointed at through a wide lens. A 360 camera such as the Insta360 X series records everything and lets you choose the framing afterwards, which suits invisible-selfie-stick shots and makes reviewing an incident much easier — the trade is more editing and two exposed lenses that scratch. Bar-mounted 360 cameras also need a longer arm to keep the bike out of frame, which means checking the mounts listings before you buy.
How long does an action camera battery last?
Expect 60 to 90 minutes at 4K and up to two hours at 1080p, less in cold weather and less again with the screen on. Riders filming a full day carry two or three cells plus a power bank, all of which sit under camera accessories. Loop-recording commuter cameras are the exception, drawing less power so they cover a ride to work and back.
What should I check on a used action camera?
Open the battery door and inspect the rubber seal for grit and splits, then look at the cell for swelling; a door that no longer clicks shut is a flood waiting to happen. Hold the lens cover at an angle under bright light to find sanding from mud, press the touchscreen across its whole area, and run the camera for ten minutes at its highest setting to see whether it overheats. Ask how many batteries come with it and whether the original frame or housing is included, since those get scarce for older bodies.
Is a used action camera good value?
Yes for bodies a generation or two old, which commonly go for a third to half of new and still shoot footage that stands up. Budget £20-£40 on top for a fresh battery and a fast microSD card if neither is in the deal. Buy new where you need warranty cover, or where the used price closes to within about £40 of a new body — the wider cameras listings are the place to compare.
