Hi all !

I would like to add a second front dashcam on my car with a custom lens to see more far away, like a zoom.

My idea is to buy a G1W or G1WH and replace the lens.

May I use a 8mm CCTV lens, or should I use a specific lens for dashcam ?
 
Like this?

Hmm not like this.
I just want to have a view approching human view.
I thought about using 6mm or 8mm lens, same size as original lens.
But I guess that dashcam lens have an UV filter, but CCTV cams doesn't.

check with @kamkar1 he has been experimenting with some lenses that might suit what you want, he knows about the CCTV stuff also
 
6-8 mm is what i feel equals what you can do with the eyes.
You can properly find lenses that already have the IR cut filter, but if not you can also get the little IR filters and then glue it to the base of the lens.

Some lenses have a square cutout at the bottom where the IR filter sit, and yet others have the same but just for a round IR filter.

You will off course have to look for a megapixel lens, dont use a cheap lens for the old fashioned CCTV cameras with low resolution.
 
Thanks a lot @jokiin & @kamkar1 !
I'm sorry but I still do not receive email notifications from this forum anymore :(
Do you have any idea where I could find medgapixel lens with IR filter already mounted ?
 
Same here, i would go insane if i got that amount of mail.
But as a result of that i may be spending too much time in here, but better that than out on the streets.

I have just lost all my favorites as my old SSD died a few days ago, so the few i had in there is lost im afraid.

Only one i have left is peau over in the states.

These sources will be less expensive than a professional specialty house like Peau Productions.

(with IR cut filters)

The above will require adding a IR cut filter with suitable optical cement (http://www.m12lenses.com/IR-Cut-Filters-s/59.htm)

Thanks all.
If my understanding is right, if I search for a GoPro lens, it should be compatible and include IR filter ?
 
can't find a good lens at a good price...
