How Nexar Dash Cams Track and Display Speed

Nexar dash cams record speed using GPS technology, not your vehicle’s internal speedometer. This means the accuracy depends on satellite signal strength and positioning rather than your car’s mechanical sensors. When enabled, the speed appears as an overlay on recorded footage, along with timestamps and location data.

GPS vs. OBD-II Speed Tracking

Unlike some high-end dash cams that connect to your car’s OBD-II port (which pulls data directly from the ECU), Nexar relies solely on GPS. This creates key differences:

• GPS advantages: Works in any vehicle, requires no wiring, and isn’t affected by car sensor errors
• GPS limitations: May briefly lose data in tunnels or urban canyons, and has a slight delay in speed updates

Where You’ll See the Speed Display

The speed appears in two key places:

1. Video playback: Embedded as a semi-transparent overlay in the corner of your recordings
2. Nexar app: Displayed in the incident report timeline with mapped location data

For example, if you’re reviewing an accident clip, you’ll see your exact speed at the moment of impact, along with a map showing where it occurred. This combination creates compelling evidence for insurance claims.

Accuracy Considerations

Under ideal conditions, Nexar’s GPS speed tracking is accurate within 1-2 mph. However, several factors can affect this:

• Signal obstructions: Tall buildings or heavy tree cover may cause minor discrepancies
• Cold starts: The first 30-60 seconds after startup may show less accuracy until full GPS lock is achieved
• Device placement: Mounting the dash cam too low on the windshield may reduce GPS reception

Interestingly, some users report Nexar’s GPS speed being more accurate than their car’s speedometer, which often shows slightly higher speeds due to manufacturer calibrations.

Legal Implications of Speed Recording

While Nexar records speed, this data could potentially be used against you in traffic violations. However, most jurisdictions require proper calibration certification for speed evidence, which consumer dash cams don’t have. The footage serves better for:

• Proving you weren’t speeding during accidents
• Documenting other drivers’ dangerous behavior
• Validating insurance claims with timestamped evidence

Police typically can’t use your dash cam speed data alone to issue tickets, but prosecutors might attempt to use it in serious collision cases. Always consult local laws regarding dash cam evidence admissibility.
