Home security cameras vary a lot in how they’re powered, where footage lives, and what you’ll pay over time. Here’s how to choose without overpaying.

Wired vs wireless

Wired cameras (Ethernet/PoE or plugged in) are the most reliable — constant power, no batteries, strong connection — but harder to install. Wireless (Wi-Fi) cameras are easy to place; battery-powered models add total flexibility but need recharging and often record only on motion to save power. Choose wired for always-on coverage of key areas, wireless/battery for spots without wiring.

Local storage vs cloud — watch the subscription

This is the cost trap. Many cameras store footage in the cloud, which is convenient but usually requires a monthly subscription to keep more than a day or two of clips. Local storage (a microSD card or a base station/NVR) has no monthly fee and keeps your video in your home — but you manage the storage yourself. Check the ongoing cost before buying, not just the sticker price.

Resolution and field of view

1080p is the practical minimum; 2K/4K captures more detail for identifying faces or plates. A wider field of view covers more area but shrinks distant detail — balance the two for the space.

Night vision and detection

Most incidents happen at night, so good infrared or color night vision matters. Look for smart detection (person/vehicle vs. generic motion) to cut false alerts, and check whether those features need a subscription too.

Privacy and power

Consider where footage is stored and who can access it, and plan power: a battery cam in a hard-to-reach spot means climbing a ladder to recharge.

Bottom line: decide wired-vs-wireless by placement, and pay close attention to local vs cloud storage — the subscription is often the real long-term cost. Then match resolution and night vision to what you need to see.
