After years of fitting dash cams, the same regrets come up again and again — and almost none of them are about the camera being too cheap. Here are the mistakes worth avoiding before you buy.
1. Buying on resolution alone
4K on the box means nothing without a sensor that can use it. A good 2K camera with a Sony STARVIS 2 sensor and HDR beats a cheap 4K one every night of the week — and night is when disputes happen.
2. Forgetting the rear camera
Rear-end collisions are among the most commonly disputed incidents, and a front-only camera has nothing to say about them. If budget forces a choice, a good single-channel camera beats a poor two-channel one — but plan for two if you can.
3. Skimping on the SD card
Standard cards fail in months under loop recording. It's the cheapest component and the one that silently costs you the footage you needed. See our SD card guide.
4. Assuming parking mode just works
Parking mode needs power with the ignition off — a hardwire kit or a battery pack. Cameras sold as having parking mode don't include what's required to use it. Our hardwire guide explains the options.
5. Mounting it badly
Too low and it obstructs your view, which is the one real legal risk; outside the wiper sweep and rain ruins the footage. High and central behind the mirror is right.
6. Never checking the footage
Cards wear, mounts loosen, settings reset after a battery disconnect. Watch a minute of recent night footage every few months — it takes less time than reading this.
7. Buying grey imports
Warranty support, UK firmware and someone to call when it misbehaves are worth more than the small saving. We're an authorised reseller for the brands we stock, which is why we can actually help after the sale.
Frequently asked questions
What's the single most common mistake?
Buying on resolution alone. A 4K camera with a weak sensor produces worse night footage than a good 2K one, and night is when most disputed incidents happen.
Is a more expensive camera always better?
No, but the sensor, HDR and parking mode implementation are where money genuinely shows. Screens, apps and packaging are where it often doesn't.
What should I budget in total?
The camera plus a high-endurance card, plus a hardwire kit or battery pack if you want parking mode, plus fitting if you'd rather not route cable yourself. Budgeting for the system rather than the box avoids disappointment.
