Outdoor Gate Control

I plan on completing this install, it would be great if you can explain the wiring (a video would be perfect) also how does the locking mechanism work? And how will I be able to install it on my gate?

I plan on purchasing the Ring Elite Video Doorbell when it is available. I will run two cat 6 from the adjacent room, one for the doorbell and the other for this lock. I am confused on how the wiring will work but I will order the three components and see what happens.
