Most dash cams store footage exclusively on a local SD card. When the card fills up, older footage is overwritten. When the camera is damaged in an accident — or stolen — the footage goes with it. When the SD card fails (and they do fail), everything since the last backup is gone.
Nexar cloud storage changes this architecture. Here's how it works, how to configure it, and the specific scenarios where it makes a material difference.
How Nexar Cloud Works
Nexar dash cams upload footage via LTE (on LTE-equipped models) or Wi-Fi when the vehicle is parked within range of a saved network. The upload process is automatic — you don't schedule it or initiate it manually.
When an event occurs — a G-sensor trigger, a parking mode activation, or a collision detected by BADAS — that clip is prioritized for upload. Routine loop recording footage is uploaded in the background on a rolling basis, oldest first, within your storage tier allocation.
Once footage is in Nexar cloud, it remains accessible from the Nexar app from any device logged into your account, regardless of what happens to the physical camera or SD card.
Setting Up Cloud Backup
- Download the Nexar app on iOS or Android and log in to your account.
- Pair your camera using the pairing process in the app — the camera will appear in your device list once connected.
- For Wi-Fi upload: In the camera settings section of the app, add your home Wi-Fi network. The camera will automatically upload when the vehicle is parked within range.
- For LTE upload (LTE models only): Activate your LTE subscription in the app. The camera will upload over LTE whenever connected — including while driving and while parked away from home.
- Set upload preferences: In the app settings, configure whether to upload on mobile data, Wi-Fi only, or both. For LTE cameras, "mobile data + Wi-Fi" provides the most complete coverage.
Managing Your Cloud Storage Allocation
Nexar cloud storage is tiered by subscription level. The key behaviors to understand:
- Event clips are stored indefinitely (within your tier's total storage limit). A G-sensor trigger or collision event is flagged and retained until you manually delete it.
- Continuous trip footage rolls over on a FIFO basis — oldest footage is removed first as new footage arrives and the allocation fills.
- Starred/saved clips are excluded from the automatic rollover. If you save a clip in the app, it's retained until you explicitly delete it.
To manage storage effectively: review your clips weekly, star anything potentially significant, and let routine trip footage roll over naturally. This way your allocation is always available for new event footage without manual management.
Accessing Footage From Anywhere
From the Nexar app:
- Trips view: Shows all recorded trips with start/end locations, distance, duration, and drive score. Tap any trip to view the associated footage.
- Events view: G-sensor triggers, hard braking events, and BADAS-flagged incidents are listed here. These are the clips most likely to be evidential.
- Live view (LTE models): View a live feed from your camera via the app when the vehicle is parked and LTE-connected. Useful for checking on your parked vehicle remotely.
- Download: Any clip can be downloaded from the app to your phone's camera roll. From there, it can be shared via email, airdrop, or direct link with an insurer or attorney.
When Cloud Storage Makes a Concrete Difference
Scenario 1 — Camera stolen after a break-in: A thief breaks into your parked car and steals the dash cam along with other valuables. Without cloud, the footage of the break-in is on the stolen camera. With Nexar cloud and LTE, the parking mode clip was uploaded seconds after the event triggered. You have footage of the theft on your phone before you even reach the car.
Scenario 2 — Camera destroyed in an accident: A rear-end collision at highway speed destroys the camera and its SD card. The insurance adjuster needs footage to resolve the fault dispute. Without cloud, the footage is in the destroyed camera. With cloud, you pull up the clip in the app from the hospital or roadside — the footage was uploaded in real-time during the drive leading up to the incident.
Scenario 3 — SD card failure: A dashcam records continuously, generating constant write cycles on the SD card. Cards fail, typically within 1–2 years of heavy use. Without cloud, the card failure loses all footage not previously backed up. With cloud, the footage was continuously uploaded — card failure only loses footage from the hours since the last upload.
Scenario 4 — Footage needed weeks later: A passenger in a rideshare vehicle files an injury claim three weeks after the trip. The SD card has been overwritten multiple times. Without cloud, footage from three weeks ago is gone. With cloud, the trip is in the archive and accessible immediately.
LTE vs. Wi-Fi Upload: Which Is Right for You
Wi-Fi upload: Free with Nexar subscription. Only uploads when parked near your saved network. If you park in a garage at home every night, this provides reliable daily backup. If you park on the street or park away from home frequently, Wi-Fi upload leaves gaps.
LTE upload: Requires LTE subscription. Uploads continuously, including while driving. No dependency on proximity to a Wi-Fi network. Essential for rideshare drivers, frequent travellers, or anyone who parks away from home regularly. The most complete protection.
Privacy and Data Security
Nexar footage is stored on your personal account. It is not shared with third parties without your explicit consent. Law enforcement cannot access your footage without a subpoena directed to Nexar — the same standard that applies to any cloud storage provider.
You own your footage. You can delete it at any time. Nexar's privacy policy explicitly prohibits using individual user footage for advertising or behavioral profiling.
The Practical Setup Recommendation
For most drivers: Nexar camera + home Wi-Fi backup + cloud storage subscription. Review the app weekly, star any incident clips, let routine footage roll over.
For rideshare drivers or anyone who parks away from home frequently: add LTE connectivity. The gap between Wi-Fi-only and LTE in terms of coverage completeness is significant — and the scenario where it matters (a theft, accident, or complaint that happens away from home) is exactly the scenario where you most need the footage.
