Hey there, if you’re running a fleet (or even just managing a handful of work trucks, delivery vans, or contractor vehicles), you’ve probably got video telematics devices on board. And if you’ve ever spent hours troubleshooting a black screen mid-trip or getting garbage footage that’s useless for accident reconstruction? You’ll know these devices aren’t “set it and forget it.” As someone who’s been in the video telematics game for years—working directly with fleets to keep their cameras, DVRs, and AI sensors up and running—I can tell you: most issues aren’t random. They’re from skipping basic maintenance. Today, I’m breaking down exactly what you need to do to keep your video telematics gear working, no fancy tech degree required. Video Telematics
First off, let’s get one thing straight: video telematics devices aren’t just dash cams (though that’s the consumer-side version). The ones we supply for fleets have multiple parts: front-facing cameras, cabin-facing cameras, rear/side cameras, a dedicated DVR unit (that stores footage), a cellular modem for real-time updates and data transfer, and usually some small AI sensors for things like distracted driving or tailgating. Each of these parts has its own quirks when it comes to upkeep, and missing one step can tank the whole system.
Let’s start with the most obvious—but most neglected—stuff: physical cleaning. I can’t tell you how many times a fleet manager calls me panicking because their front camera footage is blurry or covered in smudges, only to look at the dash and see it’s caked in road grime, bug guts, and dust. Wait, you’re thinking—road grime? That’s a thing? Yeah, especially if you have routes that go through construction zones, dirt roads, or even just areas with a lot of pollen. Cabin-facing cameras get even worse: they pick up dust, coffee spills, and even fingerprints if a driver touches the lens, which makes it impossible to see if someone’s on their phone or dozing off.
Here’s the rule of thumb I teach all our customers: clean the camera lenses every two weeks for city routes, every week for off-road or high-dirt routes. But don’t just grab that random Windex from the break room. The cameras have a protective coating—scratch that, even a paper towel with too much pressure can leave micro-scratches that mess with footage. We recommend using a lint-free microfiber cloth (the same kind you use for sunglasses) and a 50/50 mix of distilled water and isopropyl alcohol (70% is fine, no need for the heavy 91% stuff). Spray the cleaner on the cloth, not the lens—spraying directly can get liquid inside the camera housing, which fries the sensor. For the DVR unit? Wipe down the outside case to prevent dust buildup around the cooling vents—overheating is a huge killer of DVRs, I swear.
Next up: power and connectivity checks. Your video telematics device doesn’t work if it’s not getting power, or if it can’t send data to your portal. I’ve seen fleets go months without checking the power cables, only to find a loose wire under the dash that was causing the camera to cut out for 10 minutes at a time, right when they needed footage for an accident. Most of our devices connect to the vehicle’s OBD port or a hardwired power line. For OBD-connected units, make sure the port isn’t covered in dirt (if your truck has a lot of under-dash grime, that’s common) and that the cable isn’t kinked or chewed by a rodent—we’ve had that happen more times than I’d like to admit, especially in winter when mice are looking for warm spots. Hardwired units are a bit sturdier, but you should still check the connections at the DVR every month, because vibration from driving can loosen screws over time.
Then there’s cellular connectivity. The modem in your telematics device is what sends footage to your back office, and if it’s not working, you’re stuck with stored footage you can’t access until the vehicle is back in the yard. I tell customers to check the modem signal strength at least once a month, especially for routes that go through rural areas or urban canyons. How? Most of our portal has a little dashboard that shows signal bars—if it’s below 2 bars, you might need to adjust the antenna (we sell heavy-duty magnetic or roof-mount antennas for dead zones) or check if the SIM card is loose. Also, don’t forget to update the modem firmware—we push these updates automatically, but if your vehicle is out of service for a while, it might not have picked up the update, which can cause connectivity issues. That’s a quick check you can do remotely from your portal, no need to crawl under the dash.
Storage maintenance is another big one. The DVR unit stores all the footage, right? But if the storage card or internal drive is full, or corrupted, you’re not going to get new footage when you need it. For SD card-based systems (most of the smaller fleet units we supply use SD cards), you should check the card health every quarter. SD cards degrade over time, especially if they’re being written to every time you drive. Look for error messages on your portal—if it says “corrupted storage” or “low space,” swap the card out before it fails completely. For units with internal solid-state drives (SSDs), they’re more reliable, but they can still get corrupted from power surges (that’s why we recommend a surge protector kit for every installation). We’ve seen a fleet lose a full month of footage because a power surge fried the SSD—total headache. So replacing bad storage before it dies is way easier than recovering footage later, and way cheaper too.
Software and firmware updates—yeah, I know, update reminders are annoying, but they’re non-negotiable for video telematics. These updates don’t just add new features (like better distracted driving detection); they fix bugs that can cause cameras to glitch, footage to be lost, or sensors to misread things. For example, a while back we had a bug where cabin-facing cameras would black out when the vehicle was in bright sunlight—we fixed that with a firmware update, but only for devices that had their software up to date. If a fleet skipped that update, they were stuck with a blind spot during the day, which is exactly when you need cabin footage most. The good news is most modern devices do automatic updates when the vehicle is parked and has a good cellular signal, but you should still make sure that setting is turned on, and check every couple of months that the updates are actually installing. If you have older devices that don’t do auto-updates, schedule a technician to go through and do them twice a year—it’s a day of work, and prevents months of issues.
Wait, what about extreme conditions? Because if you’re a fleet that works in snow, extreme heat, or heavy rain, your maintenance routine needs to adjust. I worked with a construction fleet last year that was running their trucks in 100°F (38°C) heat all summer, and their DVR units were failing left and right. Turns out, they had the units tucked under the dash where there’s no airflow—overheating like crazy. We adjusted their setup to mount the DVR in a more ventilated spot, and told them to check the cooling vents every week for dust or mud buildup. For cold climates, snow and ice can build up on camera lenses and modem antennas, so drivers should clear them off at the start of every shift—ice on a front camera makes it look like the road is a blur, and a frozen modem can’t send data. For off-road fleets (like mining or forestry), we recommend sealing all the cable connections with weatherproof tape every six months, because dirt and water get into those connections way faster.
Oh, and driver training! That’s a maintenance step a lot of people forget. Your drivers are the ones interacting with the devices every day—if they’re touching the camera lenses, covering the cabin cam with their bag, or unplugging the power cable because it’s “in the way,” that’s going to cause issues. We do free 15-minute check-ins with all our new customers about device best practices, and I always tell fleets to remind drivers to not mess with the gear. Maybe even put a small sticker on the dash that says “Do not clean camera lens or unplug cables” as a quick reminder. I had a client where drivers were wiping the cabin cam with paper towels every time they cleaned the interior, scratching the lens to hell—once we explained to them why that was a bad idea, it stopped.
Wait, let’s talk about the stuff that’s easy to skip but has big consequences. Like regular inspections. I recommend doing a full system check on every vehicle every quarter. That means: testing each camera to make sure footage is clear, checking power connections, verifying cellular connectivity, checking storage health, and making sure the AI sensors (like distracted driving alerts) are working. For smaller fleets, you can do this yourself using your portal—most of the tools let you pull a sample clip from each camera to check quality. For larger fleets, it’s worth hiring a tech to do physical checks once a quarter, especially if you have a lot of off-road vehicles.
Let me throw in a real example here, because numbers help. Last quarter, we had a customer who was having 12% of their incidents result in missing or blurry footage. We went through their maintenance routine with them, and found they were only cleaning cameras once a month, never checking storage, and their power cables were loose on 40% of their vehicles. After implementing our routine: clean every two weeks, check storage every quarter, power connections monthly, their missing/blurry footage rate dropped to 2%. That’s a huge difference when you’re trying to prove fault in an accident or train a driver on bad habits.
Now, I know what you’re thinking: this sounds like a lot of work. But the alternative—dealing with accident claims, training drivers without footage, replacing dead devices every few months—costs way more than a 30-minute maintenance routine every week or two. We build our video telematics to be durable, but even the best gear needs a little TLC.
If you’re feeling overwhelmed, don’t be—we’re here to help.
