Cloud vs Local Storage

The most important decision when choosing security cameras is where your footage will be stored.

☁️ Cloud Storage

(Ring, Nest, Arlo)

✓ Easy setup, accessible anywhere

✓ Footage survives equipment theft

✗ $10-30/month per camera

✗ Privacy concerns

💾 Local Storage

(UniFi Protect, Blue Iris)

✓ No monthly fees

✓ Complete privacy

✓ Works during outages

△ Higher upfront cost

💡 Our Recommendation

We recommend local storage systems like UniFi Protect for most homeowners. The monthly savings add up quickly, and you maintain complete control over your footage.

Wired vs Wireless

Wired Cameras (PoE)

Power over Ethernet (PoE) cameras receive both power and data through a single ethernet cable. They're more reliable, offer higher video quality, and never need battery changes.

Best for: Permanent installations, high-traffic areas, business security

Wireless Cameras

Battery-powered or plug-in cameras that connect via WiFi. Easier to install but less reliable.

Best for: Renters, temporary installations, areas where wiring is impossible
