Basically IR Block Camera gives you a brighter picture during day time, and the colour would appear more vivid, realistic and richer. However it’s not a very good camera to use in dim light situation such as at night. A good example is the CMQ1993X camera.

IR sensitive cameras are good for both day and night uses. However the picture quality is a bit poorer, colour looks a bit off but it not too bad to affect your visibility. It’s famous of great capability to use at night with low light lens. A good example is the PZ0420 camera.

Here are some simple comparisons.

Hello Oscar,

first of all I love your blog, there is no other side with this much info about multicopter. I have a question, finally I think an ir sensitive cam with an exchange lens with ir filter is the best option. But I cannot find exchange lenses for the RunCam Skyplus. Can you give me a hint?

sorry I am not sure if there are official lens you can swap out.. probably best to get in touch with Runcam on their website!
However I find IR blocked version work just great even low light in late afternoon.
