I have started out my simple security camera project. I am able to take a picture and email that picture to my gmail (Can't get this to do it automatically at the moment).

I asked a question before about if I can detect motion using a normal camera module. Someone replied saying Yes.

I tried doing some research into how to do this but most people are using PIR sensor. Do I need a PIR sensor for motion detection?

How can I detect motion with my "Raspberry Pi Camera Module V2"?

I have the Raspberry Pi 3 Model B

Thank you for your time and help. Much appreciated!

PS. If anyone knows any example scripts that I or anyone can take a look at then please post them, Thank you!
