The first shot is ofcourse the stock lens, which I’m guessing is 3.6mm? The second is with the craziest lens I’ve ever used, if I remember correctly, it’s a 1.8mm. Had it on a analog bullet cam and it had the same problem as this, only less so. I think I saw that 2.8mm is about the most you can g…

Sorry, but I think the 2nd picture became more difficult to look at, more fish-eyed and its like looking through a door pin hole.

Yes you’re right, that’s kind of what I was saying.

Be careful that you don’t accidentally touch the reset button when you’re taking it apart. With that much distortion on the lens, I’m not sure if you’d ever manage to scan the QR code again. And if you put the original lens back on to do it, it would be tough to know if it’s in focus so that you can…

lol, didn’t even think about that. With my luck, I don’t see how that didn’t happen…

Whomp whomp. Sure, it’s bulbous, but your are seeing more of the view now. I think there are many uses here. Thanks for sharing!

It’s seeing even more than in that pic. The first black ring there is the wyzr case lens hole. The second ring there is the lens itself. The size of the ccd affects the field of view for a given lens. Larger CCD = wider field of view. I had this lens on a 1/3" ccd 4:3 analog cam, and the wyze h…

I believe the standard lens is 2.8 mm. have you by any chance measured the FOV with your replacement lens? I’m guessing if you had extra lenses lying around you probably have a protractor somewhere too. :slight_smile:

Not with that lens no. But I loosely calculated 142 degrees horizontal with a 2.1mm lens, which is about the same visible in the one above, minus the lens edge on the V2 cams. With a pan cam though, you do get some lens edge with these 2.1mm lenses. pan cam [wide pan2]

Thanks. That’s a great FOV for some of the use cases I’m pursuing. Any chance you could point me to those 2.1 mm lenses? I installed a 2.1 mm lens last night and got virtually no change in the FOV. I’m thinking it has to do with how far the lens has to screw into the housing, which changes the focal…

Perhaps, but from my experience, the 2.1mm you have is not actually a 2.1mm. The two things you have to be concerned with are FOV of the lens, and whether or not it has an IR filter. The reason being is that most of the pre HD cams use 1/3" or 1/4" CCD’s, whereas the HD cams are 1/2"+, which mathe…

My guestomit on the 2.5mm is based on the before and after pics. Not to mention the description on the amazon page makes no sense.

or on a Pan Cam
