Good to know
Are compact dash cams legal in commercial trucks?
Yes, dash cams are legal in most places for commercial vehicles. However, some jurisdictions have restrictions on windshield mounting. Check local laws and company policies before installation.
How do I install a dash cam in my truck?
Most dash cams mount with adhesive tape to the windshield. Route the power cable along the headliner and A-pillar. You can plug into the cigarette lighter or hardwire for a cleaner look.
Can a dash cam record while the truck is parked?
Many dash cams have parking mode that triggers on motion or impact. This requires a constant power source, such as a hardwire kit. Some models have built-in battery protection to avoid draining your truck battery.
What size memory card do I need?
For 1080p recording, a 64GB card stores about 6 hours of footage. For 4K, you may want 128GB or more. Use high-endurance cards designed for continuous recording.
Do dash cams affect GPS or radio signals?
Quality dash cams are shielded to minimize interference. However, some may cause slight static in radio or GPS. Mounting away from antennas can reduce issues.
How do I review footage from my dash cam?
You can remove the microSD card and plug it into a computer, or use Wi-Fi if your camera supports it. Some models have a built-in screen for immediate playback.
Are supercapacitor dash cams better than battery ones?
Supercapacitors are more heat tolerant and last longer, but they do not hold a charge for parking mode. Battery cams can operate in parking mode but may fail in extreme heat.
Can I use a dash cam as a rearview camera?
Some dual channel dash cams can be set to show the rear view on a monitor. But most are not designed for continuous display. For a dedicated rearview camera, consider a separate system.
Is 4K resolution necessary for a dash cam?
4K offers more detail, making it easier to read license plates. However, it requires more storage and processing. For most drivers, 1440p is a good balance.
Do dash cams come with a warranty?
Most reputable brands offer a one year warranty. Some provide longer warranties on their products. Always check the warranty terms before purchasing.
Final word
For most truckers, the VIOFO A119 V3 is the best compact dash cam due to its superior video quality and heat-resistant supercapacitor. If you need Wi-Fi and don’t mind a battery, the Garmin Mini 2 offers ultimate discretion. For dual coverage, the Rexing V1P Max is a solid choice.
