Scope cam

side shot

If the eagle vision is cheaper I would say steer away from that. I have one and with my cell phone I think it’s junk and give the side shot a chance. I don’t own a side shot but if I were using my cell phone for scope cam recording that would be my next option. 

I really like this one! I have the SideShot and a few other types of mounts but this is the one that I use the most.

Also you can do this if you have a camera?

I would look at Discovery Optics ScopeCam. The make a great great product and there are several different cases available for different phones. They are pretty up to date and have cases for iPhone 8 and 8 Plus. Check them out!
