Joint
resolution
As with smartphone
screens and TVs,
resolution is about to
the number of pixels
displayed during
playback, so aim
high and the images
you record will be
increasingly detailed.
Standard HD is 720p,
Full HD 1080p and
4K 2160p. Beware
of cameras falsely
claiming to be true
4K by matching their
resolution with a low
frame rate or cheating
with interpolation.

Strong
and stable
If you’re on the move,
so is your cam – often
violently – so image
stabilisation keeps
things solid to tame
the blur. An additional
gimbal might give
a steadying effect,
but it’s not always
practical, plus the
latest models are
good at battling
shake, rattle and roll.
Fancy names for this
tech include GoPro’s
HyperSmooth, DJI’s
RockSteady and
Sony’s SteadyShot.

Tough
on grime
Action cameras
designed at the
school of hard
knocks are built
to withstand dodgy
weather and rough
treatment, but not
all are created equal.
Identify your likely
pursuits and check
the specs to see
if a cam is suited
to it: whether it’s
shockproof, can
withstand extreme
temperatures, how
long it can stay in
water and so on.

For the
many
Most action cams
have a mounting
system allowing
them to be attached
to almost anything
- inanimate objects,
moving vehicles or
fluffy animals. Check
what comes in the
box and what can
be added before you
take the plunge with
a particular brand.
A good cam will have
a universal mounting
system that extends
beyond its own official
accessories to fit
third-party offerings.

FOV
A wide field of
view allows for more
action in the frame.
It’s measured
in degrees.
FPS
How many frames a
camera can capture
per second. Higher
FPS rates mean
smoother video.
INTERPOLATION
Like upscaling on
a TV, algorithms use
guesswork to digitally
create extra pixels
in images.
