installation nest nc5100ef (doorbell) vs dedicated nest camera (nc2100ef)

I already have a wireless doorbell but I want video surveillance

note that my door does not have hardwiring set up for a doorbell but it can ..I've seen people in my townhouse complex put in nest doorbells, security cameras etc .. by drilling thru the brick

so I should I just get the doorbell nest that has video surveillance included or the outdoor camera ? which has better video and surveillance? the doorbell is only 50 bucks more so if the video quality are about the same then I might as well get the doorbell for its extra features


keep in mind I don't have a hammer drill to go thru brick (and rather not buy one as I won't be drilling thru brick and concrete often ) and I'm looking for the easiest set up


here are some pics of how some of my neighbours have set up their cameras or doorbell that appear they didn't go thru brick

camera

this looks like he just screwed onto door frame and ran the wire thru the top of the door

not sure how this was done ...is wiring going thru the top of the garage ?

this looks like the nest was drilled on the side and not brick?

here's how my back door is structured:

this is inside behind the brick wall ...the wiring powers the outside lamp as well as the garage door
