I sketched my camera positons and orientation (green arrows) on ground plan:
Attachment:
tlocrt-png-1.png

I am concerned about left camera (3) under balcony. Is it actualy necessary because right camera under balcony (4) will cover entrance trough fence gate and also camera on the left corner (2) near main door entrance in house.

Cameras (8, 9) on garage wall will cover driveway and part of backyard. Also two cameras (6, 7) will cover almost 100% of backyard/garden.

I will do this project in two stages. In first stage i will connect cameras 1, 2, 4 and 6 to NVR, and in second stage rest off cameras.

I am looking at least 2MP IP cameras around 70$, and some NVR that can record 9 IP cameras.

Any advice, did I miss anything?
Thanks in advance.

I would say it is a good idea to add camera 3.
Without it bottom right corner is not fully covered.

And with it it is much better.

The thing is Camera 2 in your project cannot look behind the wall.

If we place a few bad guys there
Image

Camera 2 cannot see them
Image

And Camera 4 cannot see them all

But camera 3 sees them perfectly with pixel desnity about 195 pixels per meter:

As we can see from the picture bottom left and upper right corners are are not well covered.

Red ares on the pictures here are Identification zones (250 Pixels per Meter, 76 Pixels per Foot)
Yellow are Recongition zones (125 PPM, 38 PPF)

It took me about 10 minutes to design your project and 15 more to paste images here assuming your cameras are installed at 3 meters.

The project file for IP Video System Design Tool 9.1 has been attached.
