Strengths and drawbacks
AKASO Brave 8
- +10 m of bare waterproofing is unusual at this price — most budget cameras need the case
- +Two batteries and a full mount kit are in the box, which the big brands charge extra for
- +Takes standard GoPro folding-finger accessories
- +The largest sensor of AKASO's single-lens cameras
- −No horizon lock, so any rotation of the mount shows up in the footage
- −Stabilisation handles walking but breaks down on vibration
- −Costs more than a DJI Osmo Action 4, which has more than double the sensor area
- −AKASO publishes no bitrate or cold rating
- −No log profile and no published bit depth, so the footage grades poorly
SJCAM SJ30
- +Seven hours at 4K30 with the handle, second only to SJCAM's own C400 here
- +Two lenses with separate imaging chips, a real day-and-night system
- +5 m of bare waterproofing with no case
- +45° horizon lock, which most budget cameras omit entirely
- −The 8K mode runs at 20 fps, below the frame rate that reads as motion
- −45° horizon lock corrects lean but not rotation, unlike a 360° lock
- −Launched in 2026, so there is no owner track record yet
- −Dual lenses mean two lens surfaces to scratch, neither of them replaceable
