Quick test of just received prototype CPL (Circular Polarizer/Linear ) filter for the B4k

[rcg530]

A CPL for my B4K camera would be a nice addition. The B4K that's installed in my 2006 Toyota Highlander does pick up a good amount of the dashboard reflections in the windshield.

If CPL are not a option you can go with a flat black dashmat on top of the dashboard, i also have that in my car and its even a DIY dashmat as no one make such things for a stupid marginal little Suzuki car.
Works fine but dont look too good, but i am 100% okay with that, i drive to not walk, not to manifest or project myself as anything other than too old and lazy to walk.

It looks like a sales chance for my company! I will have a check with my colleagues also!

There are several cams which do not have a CPL offered for them, so there could be an opportunity here

Wish there was a list of CPL's sorted by size and a similar list of cams to make things easier for everyone. I like doing DIY stuff but for something like a CPL I'd rather just buy one where possible, they're not a big expense and I never seem to catch up on all my projects

I wish there was an aftermarket CPL for the 70mai units as well

It looks like this B1W CPL works well with 70mai units. Some users posted photos in the review https://www.aliexpress.com/item/33037173584.html?sku_id=67335817376

Finally, B4K CPL is ready for shipping out

Thanks for the info!!
Glad to see it is made in black.

When I asked one of the 70mai reps if they sell CPL filters for their units, the answer was "nope...we considered this but found it's not easy to make" and then he/she proceeded to ask "is it used for solving the sunlight problem? "

 

[kamkar]

Blueskysea would be wise to list the mounting diameter for their filters on their sales channels, this way other brand owners can quick determin if there is a chance it can be used on their camera.

This is the a800s lens barrel measurement. Hopefully it can be confirmed that the B1W CPL does indeed fit before placing an order.

Finally, B4K CPL is ready for shipping out

Does anybody know where I can purchase this CPL? I've had a look on Alibaba/AliExpress, Google etc.

 

[estore009]

The amazon seller said that it is on the way to the FBA warehouse! So just wait for a few days more!

 

[dashycamy]

I keep checking each day, does anyone have any information?

can take about 2 weeks to show up on Amazon, the initial processing they do isn't quick

Thanks @estore009 for sending the CPL.
It's simple to install. It comes with wipes to clean if before hand if your camera lens is dirty. Take off the inner protective plastic and slip it on. The edge is marked with BK4 and white dot on the opposite end to help align during install. Then take off the outer protective plastic.

I can see a big improvement for the recordings at night.

With CPL:




With the CPL installed it definitely looks better without the glare and long lines from the lights. I don't know if it's just an artifact from the angle of my windscreen and camera but it definitely got rid of it with the CPL installed.

You should clean your windshield to reduce the glare reflection
