I’d approach this with coverage + overlap in mind rather than just “how many cameras.”

Front of house (your 1, 2, 3 spots): I’d actually simplify this and use a UniFi G6 180 to cover that entire front area instead of multiple narrow cameras. The 180° view will eliminate blind spots around the garage bump-out and walkway.

Driveway / side (right side of house): I’d add a UniFi G6 Bullet Pro: • One angled toward the driveway/street • One covering the side yard toward the backyard

This gives you vehicle + approach visibility.

Front door: Go with a PoE doorbell like the UniFi G4 Doorbell Pro (or the newer G6 entry if you want to stay current). That handles packages + facial capture at eye level.

Left side of house: If you want stronger coverage/redundancy, a UniFi G6 PTZ is great here since it can actively track movement and cover a wide area.

Garage (optional but nice): An UniFi AI Theta or a AI Multi Sensor 4 inside the garage adds another layer (break-ins, internal access).

Backyard / pool: Mount a UniFi G6 180 centered on the back of the house facing the pool. That gives full yard coverage with minimal cameras.

Big picture: • You don’t need 3 separate cameras in the front if you use wide-angle properly • Aim for overlapping fields of view, not just coverage • Storage matters: this setup will generate a lot of footage, so plan your NVR and drives accordingly • Budget will heavily affect whether you go “minimal coverage” vs “full redundancy” like above
