Action Cameras

Buying an action camera means filming where your phone wouldn't dare: on the handlebars, underwater, on your helmet, in the sand. Compact, shockproof, and made to move with you — at Strex, you can compare a 4K entry-level model with 16MP to a 5K top-tier model with 50MP photos and a touchscreen, plus a spare battery that doubles your shooting time.

4K or 5K: what is the practical difference?

Both film in crystal clear quality for social media and the big screen at home. The 5K model offers three additional benefits you’ll notice while filming: higher photo resolution (50MP — still images you can crop into without grain), a touchscreen that makes changing settings as fast as on your phone, and more headroom in image quality for those who edit or zoom into their videos later. If you are mainly filming to share and watch back, 4K is more than enough; if you want to get both video and sharp photos from a single shot, the 5K is worth the investment.

What should you look for when choosing?

• ✔ Resolution — 4K is the standard for smooth, sharp images; 5K provides editing flexibility and 50MP photos
• ✔ Touchscreen — changing settings with wet or gloved fingers remains a challenge; menu buttons serve as a backup
• ✔ Accessory compatibility — the universal action cam mounting system fits helmet, handlebar, and chest mounts
• ✔ Battery life — action-packed days are longer than batteries; a spare battery weighs nothing and doubles your day
• ✔ Warranty — standard 2-year warranty at Strex

The battery reality that no one puts on the box

Every action camera in the world shares the same limitation: filming in 4K/5K drains power, and cold weather makes it worse — on a winter ski slope, you will see a drop in battery life. The solution isn't a larger camera, but a simple habit: keep a spare battery in your pocket (inside pocket, warm = lasts longer), swap it on the ski lift or during a break, and film in clips rather than continuously. Anyone who has once stood at the most beautiful moment with a dead battery will end up buying a second one anyway — which is why it is already included in our collection. For shots without the action — like what's walking through the garden at night — a trail camera is the stationary counterpart. You can find all our cameras in the camera collection.

Frequently asked questions

Is an action camera waterproof?

Action cameras are built for water, sand, and dust — swimming, snorkeling, and water sports are all part of the job. For deeper diving, the rule for every brand applies: use the corresponding housing and rinse the camera with tap water after exposure to saltwater.

Can I mount the action camera on a helmet or handlebars?

Yes, via the universal mounting system that almost all action cam accessories share: helmet, handlebar, chest, and tripod mounts all click into the same standard. This allows one camera to move from a bike helmet to handlebars to a selfie stick without any tools.

How long does an action camera film on one battery?

Expect roughly an hour to an hour and a half of continuous filming in high resolution, less in cold weather. The practical solution is to film in clips and carry a spare battery — swapping takes ten seconds and doubles your shooting day.

Can the touchscreen be operated with wet fingers?

A wet screen and wet fingers remain difficult for any touchscreen — which is why the camera also has physical buttons for starting and stopping. Practical approach: adjust resolution and mode beforehand while dry, and use only the record button while on the go.
