An action camera is sold on the promise that it survives anything, and mostly it does: on the helmet, on the handlebars, in the surf. Where it dies is everywhere else. In the bottom of a rucksack with a loose battery. In a car boot in August. In a wet drybag with a lens cap. In a pocket with keys. The camera is built for the ten minutes of footage; nobody built it for the twenty-three hours a day it spends being carried around. This is a list of the ten ways action cameras from GoPro, DJI and Insta360 actually break, drawn from what comes back to us with a case order attached, and the case that stops each one. 🎥
It applies equally to the three brands and to the 360-degree cameras, which have their own failure modes and get their own section. No brand is better or worse at this; the failures are about the physics of a small, expensive, glass-fronted box with lithium inside, and about how people carry it. The fixes are cheap and the cameras are not.
Part 1: Ten ways action cameras actually break
1. The lens cover gets scratched in a pocket or bag
The lens cover is the most exposed piece of glass on the camera, and it is what the whole picture goes through. A key, a zip, a grain of sand in the bottom of a bag, and the next clip has a soft patch in the middle of the frame that no amount of editing fixes. Replaceable lens covers help, but they are not free and they are not always in the bag. A camera carried loose is a camera that arrives at the shoot with a scratch, sooner or later; a camera in a hard case with foam arrives as it left.
2. The 360 lenses, twice as exposed
A 360 camera has two protruding fish-eye lenses, one on each side, and nothing else on the body is higher than they are. Whatever the camera is set down on, it is set down on a lens. Sticky lens guards are the usual answer and they degrade image quality; the better answer is never letting the naked lenses touch anything, which is what a cut foam cavity does. For 360 cameras a case is not an accessory; it is the difference between a camera that works in a year and one with a permanent halo on one hemisphere.
3. The battery door and the USB flap
The small hinged doors that seal the battery and the port are the weakest mechanical parts on the camera and the ones that keep water out. They break when the camera is thrown into a bag open, when something in the bag pushes on them, and when they are opened with cold hands. A door that no longer clicks shut is a camera that is no longer waterproof, and the next wet session ends it. In a foam cavity the doors are never loaded from the side and the camera goes in closed because there is nowhere else for the door to go.
4. Batteries shorting in a bag
Spare batteries with exposed contacts, loose in a pocket with coins or a multitool, get warm, swell, and in the worst case vent. It is rare, and it is the failure that also takes the bag, the jacket and occasionally the car with it. Every battery in its own cavity or its own cap, contacts covered, in a sealed case, is the rule airlines want and the rule that keeps the batteries alive. The flight rules are in drone batteries on a plane and apply to camera batteries too.
5. Water where it is not supposed to be
The camera is waterproof; the chargers, the spare batteries, the memory cards, the remote and the phone are not. A wet drybag, a puddle in a kayak, a rainy day of shooting with the kit in a soft bag, and the camera survives while everything that makes it useful does not. A sealed hard case for the whole kit is the answer; we explained what the IP rating means for the case in waterproof, water-resistant or submersible.
6. Salt and sand
Salt water dries to crystals in every seam of the camera and the mounts; sand works into the buttons and the door hinges. Both are fine on the day and destructive over months if the camera goes into a bag wet and salty. Rinse in fresh water, dry, and then case it; a case with a desiccant pack keeps the dried camera dry between sessions.
7. Heat in a car or on a dashboard
Action cameras already run hot. Left in a car in summer, or on a dashboard between sessions, the battery ages fast and the adhesive on the lens cover and the screen lets go. A closed case in the footwell, out of the sun, is measurably cooler than the seat, and a light-coloured case cooler again. We wrote about what heat does to electronics in a parked car in 12 everyday items that won't survive summer in your car.
8. Crushed in a rucksack
A camera at the bottom of a rucksack under a water bottle, a helmet and a rope, sat on at a lunch stop. The body survives; the screen, the lens cover and the doors often do not. A rigid case takes the load on its shell and the camera never feels it, which is the whole reason hard cases exist.
9. The mount fails, not the camera
Cheap mounts, over-tightened thumbscrews, adhesive pads on cold or dirty surfaces, and the camera goes for a swim or a fall. The mounts and thumbscrews live in the case with the camera so they are not the ones picked up from the bottom of the bag, and the spares are there when one strips.
10. Lost, left, or stolen
A small camera in a soft bag is easy to leave on a bench and easy to lift. A case with a cut foam layout has an empty hole when the camera is missing, which is noticed before the car leaves. A case with a padlock hasp on a strap through the mount is a camera that stays. It is not a sophisticated security measure; it is the one that works.
Micro cases for one camera, the batteries and the phone
Part 2: 360 cameras: a category of their own
The problem is the shape
A 360 camera is a stick with two glass domes. It cannot be set down on a lens and it cannot be carried in a pocket with anything else. The manufacturers ship a soft pouch that protects against dust and little else, and every 360 camera we see for foam cutting has at least one lens with a mark on it already.
The invisible selfie stick and the mounts
The stick, the tripod base, the bike and helmet mounts and the thumbscrews all travel with the camera, and the stick in particular is what scratches the lenses when they share a bag. Cut foam separates them; a micro case takes the camera and batteries, a small Protector takes the camera, the stick and the mounts.
The heat problem is worse
360 cameras process two sensors and run hotter than single-lens action cameras. They shut down in the sun, and their batteries age fastest of all. The case in the shade between sessions is not optional.
Lens guards versus foam
Stick-on lens guards reduce sharpness and add flare, and users take them off for quality. A foam cavity that holds the camera by the body, lenses in free air, protects without touching the glass. That is the layout we cut for 360 cameras: body gripped, domes suspended.
Part 3: The right case for each kit
One camera, two batteries, a card: micro case
A Peli 1030 or 1040 with the foam cut for the camera and two batteries, or a 1050 for a 360 camera with its stick collapsed. Pocket-size, sealed, floats, clips to a bag. It is the case for the camera that goes everywhere.
Camera, batteries, mounts, remote, phone: small Protector
A Peli 1200 or 1300 with pick-and-pluck foam or cut foam: camera, three batteries, charger, remote, a few mounts and thumbscrews, cards, the phone. It fits a rucksack lid pocket and a glovebox, and it is the kit case most people end up with.
Two cameras, a 360, a drone: 1400 to 1500
A Peli 1400 or 1450 takes two action cameras, a 360 camera, batteries for all of them, the chargers and the mounts. A 1500 adds a small drone and its controller, and is the case for the person who shoots everything and flies as cabin baggage; the flat 1500 fits under most seats. The drone side of that kit is covered in drone batteries on a plane.
Foam or dividers
Cut foam for a fixed kit and the best protection for the lenses; padded dividers for a kit that changes. For 360 cameras, foam. The options are compared in foam, dividers or TrekPak.
The layout that works
Camera in the centre, lens up, gripped by the body. Batteries in a row with a finger notch each. Cards in a slot that holds them on edge. Mounts and thumbscrews in one pocket so they do not migrate. Charger and cable in the lid or in a lid organiser. Desiccant pack in a corner. Nothing loose.

Part 4: Care between sessions
After salt water
Rinse the camera in fresh water with the doors closed, work the buttons under the water, dry with a cloth, open the doors and let it air with the battery out. Rinse the mounts. Only then into the case. Salt left in the seams is what eventually stops a door sealing.
After sand and dust
Blow, do not wipe: a wipe drags grit across the lens. A blower and a soft brush, then a lens cloth. Check the door seals for grains before closing them.
Batteries
Store at partial charge, contacts covered, in the case, at room temperature. A battery left full in a hot car for a summer is a battery with half its life gone. Charge the night before, not the week before.
Desiccant
A silica gel pack in the case absorbs the humidity the camera brings in from a wet day. Replace or dry it when the indicator changes.
Firmware and cards
Not a case matter, but the second most common "my camera is broken": a slow or corrupted card. Keep two fast cards in the case, formatted in the camera, and one spare in the phone slot.
Part 5: Flying with the kit
Action camera batteries are small enough to be under every airline's limit, but they are lithium and they go in the cabin, contacts protected, in reasonable quantity; the airline rules are in power banks in carry-on baggage and in our airline guides. A sealed case with each battery in its own cavity is what security wants to see and what keeps the batteries from shorting in the overhead locker. The flat 1400 and 1500 fit most underseat and cabin allowances; measure against your airline before you rely on it.
Part 6: Seven mistakes that end action cameras early
Camera loose in a pocket with keys
Lens scratch, guaranteed eventually. Case, or at least a pouch, always.
Casing it wet and salty
Corrosion in the seams and a door that stops sealing. Rinse, dry, then case.
Spare batteries loose with metal
A short in a pocket. Contacts covered, own cavity.
Left in the car in summer
Battery life halved, adhesives failing. Case in the footwell or take it with you.
360 camera in the manufacturer's pouch with the stick
The stick scratches the lens. Separate cavities.
Foam cut with the lens touching the wall
The foam is soft but grit in the foam is not. Lens up, in free air.
Replacing the camera instead of the lens cover
Most brands sell the lens cover as a part. Check before buying a new camera, and stop the next scratch with a case.
Frequently asked questions
Which micro case fits a GoPro-size camera with batteries?
The 1030 takes the camera and two batteries in cut foam; the 1040 adds the remote and cards. Measure your camera with its mount frame if you keep the frame on.
Which case fits a 360 camera?
A 1050 for the camera alone with the stick collapsed, a 1200 or 1300 for the camera with the stick, mounts and batteries. The foam holds the body and leaves the lenses in free air.
Do the micro cases float?
Yes, empty and lightly loaded; a case with a camera and batteries usually still floats, but test yours in a sink before trusting it on a lake.
Can I cut the foam myself?
Yes for pick-and-pluck; the method and the mistakes are on this blog. For a 360 camera we recommend cut foam, because the cavity that grips the body and suspends the lenses is hard to get right by hand.
Is a hard case overkill for a cheap action camera?
The case costs less than the lens cover on most cameras and outlives three of them. It is not overkill; it is the cheapest part of the kit.
What about the phone?
The phone is the editor and the remote and it is usually as exposed as the camera. The 1040 and M50 take a phone alongside the camera; the small Protectors take it with everything else.
Checklist: the action camera kit that lasts
- ✅ Camera in a cut cavity, lens up, gripped by the body
- ✅ Each battery in its own cavity, contacts covered, stored at partial charge
- ✅ Cards on edge in a slot; two fast cards, one spare
- ✅ Mounts, thumbscrews and stick in their own compartment, away from the lenses
- ✅ Rinsed and dried after salt or sand, before it goes in
- ✅ Desiccant pack in the case, replaced when saturated
- ✅ Case in the shade or the footwell, never on the dashboard
- ✅ Batteries in the cabin when flying, case within the allowance
The short version
Action cameras do not break on the helmet. They break in the bag, in the car, in the pocket and in the drybag, from scratches, crushed doors, shorted batteries, salt, heat and water where it should not be. A micro case for the camera and its batteries, or a small Protector for the whole kit, with the lenses in free air and each battery in its own cavity, stops all ten. Rinse, dry, case, shade. 🎥
