After a car accident, there are often two different accounts of what happened. Typically, one driver says the light was yellow, while the other insists it was red. One might say that the car in front suddenly slammed on the brakes without warning, whereas the occupants of that vehicle might say that the car behind was following bumper to bumper.
Scientific research into the psychology of memory consistently shows that our memories are imperfect and that even eyewitnesses attempting to be completely honest can be influenced by outside factors. That means that car accident legal cases can drag on for weeks, and insurance companies are often forced to make judgment calls based on incomplete information.
Smart dashcams are rapidly changing that dynamic, with small windshield-mounted cameras continuously recording the road. Many drivers now have an objective account of what was happening during and leading up to the moment of impact.
How Smart Dashcams Work
Most dashcams use loop recording, meaning that the camera starts up automatically with the vehicle and continuously records and saves short segments of video to a memory card. Typically, these fragments are one to three minutes long, but depending on the size of the internal storage, the camera can store hundreds or even thousands of these clips. When the card fills up, the dashcam simply starts recording over the oldest footage. This helps to preserve evidence because you always have access to the recent footage, and assuming you have a reasonable storage size, by the time content starts getting deleted, you're sure that you no longer need it.
But where does the smart come from? Many of the latest models add features like:
- Sensors
- Enhanced connectivity
- Software that automatically sorts through clips
In the past, dashcams have been limited by image quality, and reading details like license plates and signs was quite difficult, but the latest smart dashcams offer 4K resolution that makes seeing the smallest details possible. Several models also offer a parking mode, which keeps the camera in a low-power monitoring state while the car is left unattended in a parking lot. If the device detects motion or an impact, it starts recording a clip, which can be useful for documenting hit-and-run cases in parking lots or attempted theft.
Preserving the Evidence
Dashcams are useful after a crash if you have footage that is clear, your recording device is intact, and the footage is verifiably legitimate. Many standard models don't perform well in low-light situations. Collisions can often happen at dusk or night, and dashcams without specialist image processing can struggle to balance the bright headlights against dark surroundings.
Smart dashcams can help to verify what exactly happened by providing GPS tracking through a GPS module that embeds all footage with location coordinates and the approximate speed your vehicle was traveling. The video content also has timestamps and dates synced through GPS, proving exactly when and where events happened.
Smart dashcams also contain G-sensors or accelerometers, which can measure sudden changes in force. For example, this happens if you:
- Brake hard
- Swerve suddenly
- Are involved in a collision
When the camera detects a spike set above a certain threshold, the dashcam automatically locks the current clip so that loop recording can't possibly overwrite it.
This matters because often in the aftermath of a crash, you're too concerned with the practicalities of dealing with the emergency, such as getting medical attention and roadside assistance for your vehicle. Saving the footage is not always going to be at the forefront of the driver's mind, so by locking the footage, the dashcam preserves crucial evidence that might be necessary.
Seeking Legal Assistance After a Collision
Even with clear footage, an insurance company may still dispute who was at fault, and serious injuries or conflicting accounts can make a claim difficult to handle alone. Speaking with a car accident lawyer in Woodland Hills can help you understand how your video fits alongside the police report, witness statements, and local fault rules. It's worth bringing copies of your footage, photos, and insurance correspondence to that first meeting, so that everything can be reviewed before you accept any settlement.
Why a Dashcam is Worth Having
A dashcam cannot prevent a collision, but it can remove much of the guesswork from what happens afterwards. For any driver who wants a dependable account of events, it is a small and practical addition to the vehicle.
