Night Vision Cams Range of View

Sat Apr 30, 2016 12:39 am

I am trying to figure out which night vision cams take in the widest field of view. Any body familiar with the range of the various NV cams or what is the best way to get that info? or are they all the same?

This is a function of the lens and the light diffusion. My belkin hd cam with night vision has a very nice wide-angle lens and it 'floods' the area with infra-red light--- its fabulous.

Its all personal preference, really. The noircam for the PI is pretty good--- but I have to provide the light source ( the angle of view is ok ).

If you're looking for cameras for the PI, you've got two: 1) noir fitler, night vision 2) normal daylight camera.

Indeed... Gordon, do you have any comparative night vision shots between the two noir cameras?

Strictly speaking the NoIR camera is NOT a night vision camera, it's a camera that responds to a scene illuminated with IR light. You have to provide lots of IR light to get a usable image.

Night vision camera include photo-multipliers and are something entirely different.

Whether you could get a usable image from a photo-multiplier tube with an RPi camera (either flavour) at the eyepiece is something to ask the Astrophysicists. The military tend to be a bit twitchy about folks with photo-multipliers.

If you're after a proper night vision camera that picks up heat, the FLIR Lepton is probably the cheapest (but still expensive) option that should work fine:

If you don't mind hacking together a USB adaptor, there are also the FLIR ONE and Seek Thermal cameras. However, I don't know if they're just seen as USB webcams, or if they need special drivers.

If you don't have to measure heat, and just want to pick up objects, go for the NOIR option, because it will be significantly cheaper and easier to work with. Cheap lens kits like these may be of use to you, if you take this path:
