BlackVue dash cams offer an excellent parking mode by motion detection that has already caught a number of hit and run/vandalism incidents.The motion detection feature senses changes in light to trigger recording even if no contact is made. If a physical impact was detected, the G-sensor would also step in to record some parking video files as events. Here are just a few examples of the BlackVue parking mode in action!
Sample: Costco hit & run
Sample: Parking hit & stay
Sample: Gas station hit & run
The Problem with the DR650GW-2CH and DR650S-2CH
That being said, for the past 3 years while the DR650GW-2CH and DR650S-2CH established themselves as one of the most popular parking mode setups, there was one notable flaw in the parking mode integration. The G-sensor and event files were solely used to help you find video files more easily, however files were not actually protected. With later iterations, the cloud feature helped by alerting the user when these happened but that only helped a small portion of users. Ultimately, videos were all stored in the same way regardless of whether they were tagged as normal, event, or parking.
What this meant was that videos of different types could be overwritten by any file. The dash cam would simply record over the oldest files to make room for newer ones. So if you have a hit and run or crash that was tagged as an event, regular driving footage would delete those files. Worse yet if you're parked in a busy parking lot or street, the traffic is enough to keep your camera recording running a great risk of overwriting.
What's new with the DR750S-2CH?
The new BlackVue DR750S-2CH (and DR750S-1CH) has a feature that can be enabled called event file overwrite protection. What this essentially does is it keeps event files in a separate folder that won't get overwritten with your typical driving or motion clips. This folder can store up to 50 files and contains impacts in driving and parking mode as well as manual recording clips triggered by the touch sensor on the left side of the device.
While it's not the most customizable or sophisticated memory partitioning setup out there, we feel that it's a necessary improvement over the DR650S-2CH. This along with the various video quality and high heat upgrades make the new dash cam a much stronger competitor in our books.
