Budget action cameras
The sub-$300 tier, where the headline specifications look close to a flagship's and almost nothing behind them is. What you give up, consistently: horizon lock, which most of these do not have at all; bare waterproofing, because the depth on the box usually belongs to the plastic case in the box; sensor area, which is where low-light performance lives; and stabilisation that works on anything rougher than a walk. What you get is a camera that costs less than a flagship's spare batteries, arrives with two batteries and a bag of mounts, and does not hurt to lose. Owners are consistently happy with these for holidays and pools, and consistently unhappy with them on a bike.
We track 13 budget action cameras from 3 brands, priced ~$69 to ~$279. The largest sensor of them is in the AKASO Brave 8 at 31 mm², and the least expensive is the Campark V40 at ~$69.

AKASO
AKASO Brave 8
AKASO's flagship, and the one model in its line with a 1/2-inch sensor rather than the 1/2.3-inch chip the rest of the range shares. Two colour screens, 4K60, 48 MP stills, 10 m of bare waterproofing and two 1550 mAh batteries in the box put it on paper somewhere near a mid-range DJI. In use the gap shows where budget cameras always show it: stabilisation that copes with walking but not with vibration, a noticeably slower interface, and no horizon lock, which is the single feature that makes handlebar and helmet footage watchable. Priced at $279 it sits awkwardly close to a DJI Osmo Action 4 with more than twice the sensor area, which is the comparison to make before buying.

Campark
Campark V40
Cheapest dual-screen camera in the catalogue, and the front display is the only reason to pick it over Campark's own X30. At $69 it does the basics: native 4K30, 20 MP stills, 10 m of bare waterproofing — which several cameras three times the price do not offer — and a 40 m case for anything deeper. Everything about the image is what the price implies, and the list of things it does not have is long: no horizon lock, no log profile, no published bitrate, no 4K slow motion. It is a camera for a pool, a first bike, or a second angle on a trip, and nothing about it pretends otherwise once you get past the packaging.

AKASO
AKASO EK7000 Pro
The cheapest camera in this catalogue, and it has been AKASO's volume seller for years by being exactly what a first action camera needs to be: 4K30, a touchscreen, a waterproof case, a remote, a mountain of plastic mounts and a price that makes the decision easy. It is also where every corner has been cut. There is no bare waterproofing, no horizon lock, no USB-C, no published weight or runtime, and stabilisation that only works below 4K. The realistic use is a kid's first camera, a snorkelling trip, or a second angle nobody will grade. Anyone planning to actually edit the footage should read the GoPro HERO row instead and find the extra ninety dollars.

Campark
Campark X30
Sold as a 4K60 camera, and the spec sheet on Campark's own site quietly says otherwise: native 4K is 3840×2160 at 30 fps, and the 60 fps mode runs at 3200×1800 — upscaled to look like 4K in the file. That is worth knowing, because it is a pattern across the sub-$100 tier rather than one brand's failing, and it is the reason this catalogue records a native resolution and frame rate rather than the box copy. What you get for $89 is a competent daylight camera with a touchscreen, two batteries, a 40 m case and standard GoPro mounting. Electronic stabilisation cannot run alongside distortion correction, so you pick one. The card ceiling is 64 GB, which is low.

AKASO
AKASO V50X
Under a hundred dollars with a touchscreen, electronic stabilisation, 4K30 and a 40 m case, which is roughly the floor of what is worth buying at all in this category. The honest framing is that this is a snorkelling and holiday camera: put it in the case, take it in the water, and accept that the footage will look like $99 the moment the light drops or the mount vibrates. Against the V50 Elite it loses 4K60 and voice control for fifty dollars. Against a GoPro HERO at $179 it loses on image quality, stabilisation, and the fact that the GoPro needs no case at all — which is the comparison most people should actually run before the price tag decides it.

AKASO
AKASO Brave 7 LE
Six years old and still selling, because a dual-screen 4K camera with an external microphone jack under $150 does not otherwise exist. The front screen is the reason people buy it: at this price nothing else lets you frame yourself, and the mic input means a lav or shotgun can replace the tinny built-in audio that ruins most budget footage. What you accept is a 4K ceiling of 30 fps, so no slow motion above 1080p, and an IPX7 rating that means splashes rather than swimming — the 40 m case is not optional if it is going near water. Treat it as a cheap talking-head and travel camera rather than a sports one.

AKASO
AKASO V50 Elite
AKASO's long-running budget workhorse, and the cheapest camera in this catalogue that shoots 4K at 60 fps rather than 30 — which, on a bike or a board, is the difference between footage you can slow down and footage you cannot. Voice control is unusual at the price too. Everything else is what $149 buys in 2026: a 1/2.3-inch sensor, electronic stabilisation that smooths a walk and not much more, no bare waterproofing at all so the supplied 40 m case does all the work, and a camera design that has not changed since 2019. AKASO does not publish a weight, a bitrate or a runtime for it, which tells you something about the documentation standard across the budget tier.

SJCAM
SJCAM C300
A pocket-shaped body rather than a GoPro-shaped one, and the whole design is organised around recording for hours: a 1000 mAh camera battery that clips into a 2800 mAh grip, for a claimed six hours at 4K30. That makes it a body-cam and vlogging tool more than a sports camera, which is how SJCAM markets it. Dual touch screens, six-axis gyro stabilisation, a 30 m case. The limits are the usual ones at $159 — 4K30 with no horizon lock, no bare waterproofing, and no published bitrate — plus a form factor that does not sit as well on a helmet as a standard action-camera body does.

AKASO
AKASO Brave 8 Lite
Drop the front screen and the 1/2-inch sensor from the Brave 8, keep the 4K60, the 48 MP stills, the two 1550 mAh batteries and the 10 m bare waterproofing, and take eighty dollars off. That is a reasonable trade at $199, and the wristband remote AKASO ships instead of the front screen is arguably more useful on a helmet than a screen you cannot see anyway. The sensor drops to the 1/2.3-inch chip most budget cameras use, so low light is where this gives up first. What it is genuinely good at is being the camera you take somewhere you would not take a $400 one: two batteries, a full mount kit, a case rated to 40 m, and nothing to cry about if it comes off a handlebar.

SJCAM
SJCAM SJ20 Dual Lens
Two lenses on the front, and neither of them is for 360 capture. One is an f/2.0 daylight lens; the other is an f/1.3 night lens, and the camera switches between them. It is the only camera in this catalogue that solves low light with optics rather than a bigger sensor or noise reduction, and for night riding or filming from a car that is a genuinely different answer. The cost shows up everywhere else: 4K stops at 30 fps, the bitrate is 25 Mbps — the lowest here by a factor of five, and low enough that fast motion visibly falls apart — and there is no horizon lock. It did surprise on endurance, running 2 hours 17 minutes in an independent four-camera drain test, third of four and ahead of a camera costing twice as much.

SJCAM
SJCAM C400
A 54 g camera module that drops into a handle carrying a 3000 mAh battery and a big rotating screen — the same split-body idea as the DJI Osmo Nano and Insta360 GO Ultra, executed at half their price. Seven hours and seventeen minutes at 4K30 with the handle attached is the number SJCAM leads with, and nothing else here approaches it. What it does not have is the sensor those two carry: 1/2.3-inch against their 1/1.3-inch and 1/1.28-inch, roughly a quarter of the imaging area, which is the whole difference in low light. Nor is there bare waterproofing. Read this as a very long-running vlogging camera rather than a small flagship.

SJCAM
SJCAM SJ30
SJCAM carried the SJ20's two-lens idea forward and gave each lens its own imaging chip and processing path, which is a more serious piece of engineering than the price suggests. The headline is 8K, and the honest reading of it is 8K at 20 fps — below the 24 fps that reads as motion, so it is a stills-adjacent mode rather than a usable video one; 4K60 is the real ceiling. What is unambiguously good is endurance: a 2000 mAh internal cell plus a 4200 mAh power handle gives a claimed seven hours at 4K30, which is longer than anything else here by a wide margin. Horizon lock is the 45-degree kind, which corrects lean but not rotation.

SJCAM
SJCAM SJ11 Active
SJCAM has been building GoPro-shaped cameras longer than most of the brands that undercut it, and the SJ11 Active is its mainstream model: a Sony IMX415 behind a Novatek processor, dual screens, 5 m of bare waterproofing and 30 m in the case. The sensor is the smallest in this catalogue at roughly 18 mm², and the headline 20 MP is an interpolated figure rather than a native readout — worth knowing before comparing it to the 48 MP numbers elsewhere in the budget tier, which are produced the same way. Where it does well is the dual-screen layout and a 4K30 image that holds together in daylight. Slow motion is 1080p120, and there is no horizon lock.
