hello， The Nikon-EOS adapter ring fit for nikon AI mount lens and canon EF camera. so the adapter ring fit for your Nikkor 55mm 3.5 ain’t lens on to canon 80d 

Yes and no. Using motion detection it doesn't work through a window. However.... using the timer inside it you can record through a window using it. How? Set the timer to record 4 minutes every 5 minutes for 1-5 hours or whatever time you need it to record for. This is what I do- just make sure you have a SD card with enough memory for the videos- I use a 32 GB SD card, I use it though a window as a security camera for my car....I live in an apartment so I can't hard wire anything and this works great for what it is. 

No the other way this is to be able to mount the Nikon lenses onto the micro 4/3 camera body 

1. please judge whether your lens could adjust the aperture there is only Nikon(G),also called AI(G) adapter ring has the aperture control ring, and is only for Nikon G lens,
   If you want to use nikon AI lens on this Nikon(G) adapter ring, it could be attached, but the aperture control ring could not be used as
   there is a pin on Nikon G lens that could move the aperture control ring but no on AI lens.
2. Some buyer mentioned could not adjust the aperture, actually this is because your lens does not have the aperture control function, If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default
3. Since there is no electronic contacted on our adapter ring, so could not transfer the aperture number to camera.

 

I have come to find out that adapter is not compatible with the nikon d5200 and all things would be done manually
