A dash cam is cheap insurance right up until you need the clip and it isn't there. Most of the fleets we deal with bought the cameras, mounted them, and never thought about the footage again — which means the one time it matters, nobody can produce it.
It isn't really a camera problem. It's a data problem, and it behaves like every other data problem: fine for months, then catastrophic on exactly the day you can't afford it.
1. The clock is shorter than you think
Dash cams record on a loop, overwriting old clips as they go. A 64GB card running front and rear at 1440p often loops in two to four days of normal driving. Hence the usual failure: an incident on Friday, the insurer calls Wednesday, footage gone.
Cards fail too. Continuous writing is brutal on a standard microSD, and they fail silently — the light stays on while the card has been corrupt for weeks. Nobody finds out until somebody goes looking for a clip.
Use high-endurance cards — they're built for constant rewriting and cost a few dollars more. Then check that one clip per vehicle actually plays, once a month. That's the whole maintenance routine.
2. Get the footage off early
If retrieval means tracking down the vehicle and pulling the card, it only happens after something has gone wrong — which is exactly when it's already been overwritten. Pick whichever of these you'll actually keep doing:
- Wi-Fi to phone
Fastest option, and it's free. It only works if drivers flag incidents the same day, so it lives or dies on the habit rather than the tech.
- Cloud upload
Convenient, and an ongoing cost. Check the retention terms and where the data actually lives before you commit a fleet to it.
- Weekly manual offload
Perfectly fine for a handful of vehicles — provided it lands somewhere your existing backup already covers. A folder on one laptop is not a backup.
Saved footage is only saved if it's included in whatever backs up the rest of your business. Copying clips off the card and onto the same machine that's never been backed up hasn't solved anything — it's just moved the risk.
3. Don't skip the privacy side
Cabin cameras that record audio fall under surveillance and listening-device laws, and those differ from state to state. Tell your drivers in writing — a camera they didn't know about creates a workplace problem that has nothing to do with the footage itself.
Number plates and faces can be personal information under the Privacy Act, though most small businesses — broadly, those turning over under $3 million a year — sit outside that Act entirely. Either way, the sensible move is the same: set a retention period and stick to it. Routine footage loops and disappears; incident footage gets kept for the life of the claim and no longer.
This is general information, not legal advice. If you're recording audio, or running a larger fleet, get proper guidance for your state before you switch anything on.
Not Sure Your Backup Covers Any of This?
We look after the unglamorous end of small-business IT across Brisbane — backup, storage and the "where does that actually get saved?" questions. Usually a remote job.
Book a Tech4. Install it properly
A suction mount off the cigarette lighter records perfectly well, and it also drops off the windscreen in a Brisbane summer, dies with the ignition, and can't do parking mode. A hardwired install with a voltage cut-off gives you parking surveillance without waking up to a flat battery.
Fuse taps and earthing are easy to get subtly wrong, and a slow parasitic drain is a miserable thing to chase down months later. If you'd rather not do it yourself, look for an installer who comes to the vehicle instead of booking it into a workshop for the day — most capitals have them, and in Melbourne, for example, Schmicko do mobile dash cam installation on site.
5. The five-minute version
If you do nothing else with this article, do these:
- Check one clip per vehicle actually plays
Not that the light is on — that a file opens.
- Swap to high-endurance cards
Cheap, and it removes the most common silent failure.
- Know your loop window
Two days or ten? You can't make a retrieval policy without that number.
- Make sure saved footage is backed up
It has to be inside whatever already protects the rest of your data.
- Write a one-page policy
Audio, retention, and who is allowed to access footage. One page is enough.
None of it feels urgent until the day it's the only thing that matters.
