Thanks for the tips. Not sure about doorbell, these days all good doorbells are wireless.
I have a corner townhome, which has three walls open to the outside. Seems like 3 cameras should be good. I may add one more at the side wall, since its pretty long and one cam won't be enough.
Hi Bender,
I have seen thieves turn their backs on cameras reducing the chance of a good facial image.
Since all 3 sides are exposed to the public, I would plan for 2 cameras per side + one WIRED video doorbell / intercom product.
Even if you decide to go with just 3 cameras total today - now is a good time to wire each corner of your unit with 2 cables each. ( 4 corners x2 = 8 cables, + 2 cables for the front door )
This way, you can even use one of the cables to supply power to a LED or IR LED illuminator, or to a PIR sensor if you like.
If you need license plate captures on any of those sides, that would be one more camera.
If you park across the street - that would be a camera with narrow FOV and zoom.
