I have seen cameras similar to CEO5784 such as this at
There are cameras on the market with various field of view angles at 60, 75, 130 degrees.
Can a lens be purchased in order to swap say a 130 degree lens with a 60 degree lens.
One more question please:
Is there an enclosure/stand that one can purchase to hold this particular camera in place.
Note the enclosures advertised at an overseas vendor don’t necessarily fit this camera:especially the width is not the same and cameras that look like the one sold at core has a third light sensor.
So please I would like to purchase a stand to hold this particular kind of camera.
There are a lot of really similar camera setups available from our supplier. We don’t receive the lenses or IR lamps as separate products, we just stock the variants of the camera we think will be the most popular and useful.
The three super similar variants of this camera we do carry are below, if there is a combination of IR, adjustable focus, and viewing angle you need that we don’t carry, then let us know and we can look at bringing it into our range.
Since they are an odd shape we don’t have enclosures that fit this range of cameras. A 3D printed case, or modified Tupperware container are probably the fastest way to get a good custom-fit case.
Thank you for the reply.
Given the different field of view angles means that the resulting images will be “distorted”.
Is there an algorithm to process and correct the image for different angles such as 160 degrees and 60 degrees?

There might be simpler ways to do this, but it looks like OpenCV is happy to correct for “fisheye” effect for you:
As far as the FOV distortion that “stretches” stuff at the edge, there’s not a whole lot you can do about that though, it’s inherent with short focal lengths. One thing you can do is crop down on the center to simulate a longer focal length though, you’ll find that it actually looks exactly the same as if it were taken at that longer length!
If you’re interested in cameras and lenses there’s a good free online set of videos on it by a google camera engineer:
Thank you for the reply.
I had a look at the referred google page, if one camera introduces distortion, and another camera introduces distortion, when doing object and face detection, how is image distortion taken care of?
Put it another way: there is camera X and camera Y. Both take identical images.
Will the results from the object and face detection algorithms be the same in spite of the different distortion factors of camera X and camera Y?
