G1W-H Car DVR Dashcam with Polarizer Filter

In this video I install a circular polarizer filter on my G1W-H dashcam to help reduce reflections seen on the windshield.

You will see how to select the right orientation on the filter, and also sample footage during both day and night time.

Parts used:
34mm to 37mm step-up ring
37mm Circular Polarizer filter
G1W-H car dashcam
BlackVue DR400G-HD for comparison footage

The video was recorded with my OnePlus One smartphone – I think it did a decent job.

BlackVue DR400G-HD Lens Cleaning and Battery Replacement

After an infamous thread on RedFlagDeals regarding an insurance fraud scam foiled by a person’s dashcam, many people started installing them as their own insurance, or simply to point out and ridicule poor drivers.  Sometimes people catch some crazy events.  I ended up purchasing a BlackVue DRG400G-HD from a group buy.  It was one of the better cameras at the time, 1080P recording, GPS, and a nice sleek build.  There are more affordable ones out there now such as the G1W which I have installed for my family members.

Most recently I captured lightning striking a utility post and it took out power to a traffic intersection.  When I went to check the footage, I found that the image quality was very poor.  I knew it was getting worse but always attributed it to a degrading sensor due to summer heat.

My camera also had an issue shutting down — it would no longer say “BlackVue now shutting down” when the power was cut.

Instead of tossing it for a new one, I opened it up for a little bit of maintenance to get it running like new.
