The G-sensor and graph features from BlackVue dashcam saved the day.

An anonymous user came to our service centre to ask for assistance to find any video related to a "hit and run" incident.

His rear car bumper was badly scratched while he was away parking on a busy roadside in broad daylight. He couldn't find any notes on his car when he noticed the damage before driving off. 
While searching the video, we found an event file recorded during the period of parking mode he mentioned. It is not easy to spot the video with the shake from the rubs and impact of the taxi. Watch the video:

Fortunately, when we used the dedicated BlackVue PC Viewer software, the G-sensor shows the impact clearly on the graph. G-sensor graph is a built-in feature only available in the BlackVue Viewer software. It plotted the graph of the impact detected by the G-sensor and synced with the video. A clear map also shows the location of the incident. 

The user was relieved as he could now prove that the damage was due to the reckless actions of the taxi driver. With the clear evidence retrieved from his BlackVue dashcam, he could submit a detailed report to his insurance company and authorities for follow up. We wish him all the best! 

All BlackVue dashcams come with a built-in 3-axis G-sensor and supports the free dedicated PC Viewer Software for Windows OS and Mac OS.  
​Users can set the sensitivity of the G-sensor for each axis using the PC Viewer Software or smartphone app. There are two sets of separate G-sensor settings, one for "driving" and the other one for "parking". If the G-sensor detects an impact above the threshold settings, it will mark the file as an "Event" so it can be searched easily if needed. Please take note that if the sensitivity is set too high, it may cause  unnecessary false alarms.
For BlackVue App, you can find these settings on:
Firmware settings > Sensitivity > G-sensor 
​
For PC Viewer software:
Firmware settings > Event triggers 

If the cloud dashcam is connected to BlackVue Cloud service, there are options to send you an immediate push notification and to save the event. file to the cloud storage as backup. If the dashcam is a non-cloud model or it's not connected to the cloud service, the dashcam can also alert you of the event through voice guidance when exiting the parking mode. ​These features are extremely useful to alert you of any possible impact on the car when you are away, so you can have a closer look without delay. ​

For this particular case, this user is using the DR750X-2CH Plus, a popular dual-channel cloud dashcam which was released in the mid of 2021. The successor model, DR770X-2CH which was released earlier this year comes with a new processor for an improved image quality. You can learn more about the wide range of our BlackVue dashcams here.
