Is a Front Dashcam Enough? One Fleet Buyer's $7,400 Lesson

The Question I Used to Get Wrong

Every month, somebody asks me, 'Is a front dashcam enough?' Usually it's an ops manager at a construction company or a dealer trying to build a boat package. My old answer was, 'For basic coverage, sure.' After seven years and about $7,400 in documented mistakes, my answer is different: it depends on what you're trying to protect—and most people are protecting the wrong thing.

I handle fleet electronics orders for a regional industrial services company with 35 trucks and 4 workboats. I've been doing this since 2018, and I've personally made—and documented—11 significant mistakes that added up to roughly $7,400 in wasted budget. I maintain our team's installation checklist now, mostly because I don't want anyone else to repeat the stuff I did.

I've learned to ask what's NOT included before what's the price. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.

The mistake that hurt the most happened in September 2022. A truck backed into a dock arm at a job site. The driver said the spotter gave the signal; the spotter said he didn't. We had a front dashcam, and it showed the truck moving backward—but not the impact, because the impact was behind the truck. $3,200 in body damage, a disputed insurance claim, and zero video evidence. That's when I started questioning the whole setup.

What a Front Dashcam Actually Covers

Here's the weird part: a front dashcam is not meant to cover your vehicle. It's meant to cover what's in front of the windshield. That's great for collisions with cars, pedestrians, and road debris. It's not great for backing accidents, side swipes, rear-end hits, parking lots, or dock strikes.

According to Garmin's spec page, the Dash Cam 67W records 1440p and has a 180-degree field of view. That's seriously wide. But 180 degrees still doesn't see the back bumper. I needed a yard of rear visibility, not a ton of front detail.

So when someone asks 'is a front dashcam enough,' the honest answer is: it's enough if every incident happens in front of the vehicle. Otherwise, you're gambling. I don't like gambling with insurance premiums.

The Deep Problem: Power, Wiring, and Invisible Costs

The mistake I kept repeating wasn't buying the wrong camera. It was treating every device as a standalone purchase. We added Garmin dash cams, a Garmin GPS tracker, phone chargers, and then—on some trucks—a Starlink Mini for remote crews. Each piece made sense on its own. Together, they became a power problem.

The Starlink Mini wants a fair amount of wattage. If I remember correctly, it's somewhere in the 40-60W range depending on what it's doing, but don't quote me on that because they update the firmware. The point is, you can't just plug it into a random 12V socket and expect the battery to stay happy. Portable power for Starlink Mini isn't a marketing phrase; it's a requirement. You need a dedicated power station, and you need to charge it on purpose, not passively.

Let me give you a ballpark. A dashcam in parking mode draws maybe 0.2 to 0.5A. A Garmin GPS tracker is small, maybe 0.1A. A phone charger is 1A. A Starlink Mini at 50W is over 4A at 12V. Add a few accessories and you've got a battery draining overnight. That's not a malfunction; that's basic arithmetic.

We learned that the hard way in November 2024. A crew took a Starlink Mini to a remote site and plugged it into the truck's auxiliary socket. It worked for one call, then tripped the fuse. They lost the video connection in the middle of a safety briefing, and we looked like we didn't know what we were doing. I should add: the fuse wasn't even the problem. The problem was nobody had calculated the total draw. Oh, and the cable gauge was too small, which made the fuse do its job instead of the electronics working.

That's also how the Weego 70 jump starter became part of our standard kit. After a different truck's dashcam parking mode and GPS tracker drained the battery over a long weekend, I bought a Weego 70 for every vehicle. It's not a luxury. A tow is two hours and a lot of money; the jump starter is five minutes and no phone call. The math is a no-brainer.

But please don't read that as 'just buy the Weego 70 and you're fine.' It's a safety net, not a solution. If you're jumping a battery more than once a year, your power budget is wrong.

What 'It Stopped Working' Actually Meant

After the third dead-battery incident, I started documenting every failure. The pattern surprised me: most of our electronics didn't stop working. They lost power, lost connection, or lost installation quality.

• Garmin GPS tracker: silent for a week. The device was fine; it was wired to a circuit that switched off with the ignition. A tracker that's off is just a very expensive magnet.
• Front dashcam: kept recording, but the mount loosened and the view pointed at the hood. No one checked it until a driver asked for the footage. Ugh.
• Marine electronics: a Garmin chartplotter on one workboat was installed without checking the house battery. It worked—until the anchor lights and radio were on too. Then it shut down at the worst time.

On the Garmin Marine side, I see the same mental error: a boat gets a beautiful chartplotter, but no rear view of the dock and no backup camera. A 20-foot boat in a crosswind doesn't care how good your charts are. You need to see the dock, the lines, and the corner of the boat.

These were not expensive equipment failures. They were expensive integration shortcuts. Looking back at my notes: $3,200 for a rear collision we couldn't prove, $1,850 to rewire tracker circuits on 12 trucks, $950 in tow calls before the Weego 70s arrived, and around $1,400 in misc harnesses and adapters that never fit the intended install. That's $7,400 without counting the hours I spent apologizing.

How I'd Spend It Differently (Skip the Regret)

If I could go back to 2020 and start over, I'd do these five things before ordering anything.

1. Map the coverage. Draw the vehicle or vessel. Mark where an incident could happen. Then choose cameras and sensors for those zones—not for the windshield.
2. Add up every amp. Write down every device: dashcams, tracker, Starlink Mini, chargers. If the total is close to the circuit rating, add a dedicated power source and install a low-voltage cutoff. This one step would have saved the biggest chunk of that $7,400.
3. Specify portable power for Starlink Mini as a line item. If you're running remote sites, buy a separate power station and charging schedule. The truck battery is not the backup.
4. Buy the jump starter before you need it. The Weego 70 or something comparable—just don't make it the whole plan.
5. Ask what's NOT included on every quote. Wiring harnesses, mounting kits, installation labor, Ethernet adapters, power distribution, and software subscriptions all add up. A quote that hides those costs is a red flag.

One caveat: my experience is based on 35 trucks and 4 workboats in one region. If you're managing a heavy-truck fleet or a marina full of yachts, your specific failure modes will be different. The checklist still works—just adapt it to the real environment.

The Bottom Line

Is a front dashcam enough? No. Not because Garmin's cameras are weak, but because risk doesn't line up with the windshield. The camera that matters is the one that sees the incident. Sometimes that's front, but often it's rear, side, interior, or the dock.

I still kick myself for the 2022 rear-collision mistake. If I'd asked what's not covered instead of what's the price, we'd have ordered a rear/backup view and a proper power plan, and that $3,200 would still be in the budget. The gear is not the hard part. The system around it is. Plan for the incident, not the windshield—and get the power budget in writing before you buy the first camera.
