Security camera types and where to place them
Outdoor bullet cameras: Wide viewing angle, weatherproof, good for driveway/yard. Placement: corners of house, 8-10 feet high. Indoor cameras: Smaller, can be hidden, good for living room/nursery. Placement: shelf, high corner, out of reach. Video doorbell: Captures package delivery, visitors, doorbell footage. Placement: front door. Night vision: All modern cameras have IR night vision (black & white). Look for clear night video, not blurry. Key specs: 1080p minimum (2K+ if you need face recognition), 110-120 degree field of view, weatherproof IP65 rating (outdoor). Cloud recording (free 24-48 hour clip storage) or SD card (local recording, more privacy, no cloud fees).

Motion sensors, door sensors, and automation
Motion sensors ($20-50): Detect movement, trigger camera recording and app notifications. Place at entry points, hallways, garages. Door/window sensors ($15-30): Detect open/close. Trigger alerts, automate lights (when you arrive home, lights turn on). Place on all exterior doors and windows. Smoke/CO detectors: Smart (Eve Smoke, Eve CO) detect and send alerts. Add to bedroom, kitchen, garage. Automation examples: Motion detected at garage → Garage camera starts 10-second recording. Front door opens at 3 AM → Send alert + turn on lights. Windows open → Send notification if system is armed. Doorbell pressed → Record 60 seconds and send video clip.
Wired vs wireless vs hybrid systems
Wireless (battery cameras): Easier setup (no wires), flexible placement. Downside: Batteries last 3-12 months (replace regularly), slower response. Best for renters. Wired (powered cameras): Constant power, faster response, no battery replacement. Downside: Requires electrician/drilling, harder to move. Best for long-term security. Hybrid: Wired hub + wireless cameras. Optimal setup. Hub does person detection locally, cameras send video back. Recommendation: Start wireless (cheap, renter-friendly). If you own home and want pro setup, go hybrid or wired.
Cloud storage vs local recording
Cloud storage: Automatic video backup to manufacturer's servers. 24-hour free tier (clips only), paid plans ($10-30/mo for 30-day history). Risks: Privacy (data on servers), subscription model. Benefits: Access anywhere, automatic, redundancy. Local recording (SD card/NVR): Videos stored on device or hub locally. No cloud fees, full privacy, you own data. Risks: Limited storage (32GB = 5-10 days of recording), device theft = loss of footage. Best practice: Mix both. Local recording on hub (primary, private) + one month cloud backup ($20/mo for 3-camera system) as safety net.
