Another sun glare thread by Scruit

[Scruit 0]

Ok, figured I'd follow up on the who sun glare thing with my dash cam. Here's 3 example images showing the evolution of the "front camera" in my car to it's final config.

 

 

1) No-name ebay bullet, manual iris: $75

 

 

 

2) Panvigor box camera, noname auto iris: $120

 

 

 

3) Toshiba IK-6410A box camera with Fujinon auto-iris lens: $200

I imagine a decent WDR could handle this...........

Maybe look for a WDR Bullet camera.

KT&C is supposed to have one of those but it looks pretty large from the image I saw.

You know, I'm actually pretty happy with the final image above. You can see my lane position and the location of other cars, and that's all that really matters. I'm not looking to identify cars by license plate etc.

 

In the first image my lane position was simply not visible. In the second it was kinda visible. in the 3rd image the lane marker is right under the 'ray' from the sun - watching the video makes my lane positon clear.

 

This is only the first time in 2 months with this camera that the sun was bright enough to make the rest of the image dark. For the most part IF the sun is visible then the image is still perfectly clear.

 

 

 

Was just trying to make the point that the cost of the camera / name brand etc DOES make a huge difference even when the specs like TVL / pixels are exactly the same.

in all fairness to the ebay bullet, the toshiba had clouds somewhat blocking its sun

No it didn't. Looks like it on the pic, but the sun was peeking between clouds.

I think the last camera does a good job it's your positioning of the camera that is wrong. You have too much sky, and so your chances of getting the sun and sky glare near the centre of the picture is greater and automatic BLC won't kick in. You could use your cameras's manual BLC settings to mask out the sky, or you could angle the camera down more 'wasting' picture on the car bonnet instead of the sky.

 

The problem is the angle. If you could mount it from near the roof then that would be a much better situation and your automatic BLC would work perfectly.

 

PS the first camera obviously has no infra red filtering and are useless for this situation.

The camera is aimed upwards to show the status of traffic lights. if I aim it any further down then you can't see if the light is red or green when I'm sitting at the front of the line.

 

Same goes for any kind of shading...

 

This level of glare is vary rare. I have not been able to find another example of this amount of glare in the last 2 months. Even with that much glare you can still see lane position, and even if the front camera was utterly blind you can still see lan position form the rear camera.

 

I can live with this rare intermittent glare much easier than I can live without seeing the staus of traffic lights...

Oh good point about high traffic lights. I"M going to do a in car camera system , 1looking out the back, 1 out the front, and traffic lights in shot is something I should consider, though where I live the traffic lights are quite low, 1 light about 7 feet above the ground and another higher up. Don't use those overhead traffic lights they do in some countries.
