The first real decision when buying a security camera is power: wired or wireless. Both work well, but they fail and frustrate in different ways. Knowing the tradeoffs up front saves you a return trip to the store.

Wireless (battery) cameras

Battery cameras are the easy button. No electrician, no drilling for power, mount almost anywhere in minutes.

The tradeoffs:

  • Recharging. Batteries last weeks to months, then you climb a ladder to recharge or swap them. A small solar panel mostly solves this.
  • Event-only recording. To save power, most battery cameras record only when motion triggers, not 24/7. Brief clips can miss the start of an event.
  • Wi-Fi dependence. They lean hard on a strong signal at the mount point. A weak signal means delayed or dropped alerts.

Wired cameras

Wired cameras run on constant power, often over a single Power-over-Ethernet (PoE) cable that carries both data and electricity.

The tradeoffs:

  • Harder install. You run cable, which may mean drilling through walls or hiring help.
  • Always-on recording. Constant power enables true 24/7 footage and instant response, with no battery anxiety.
  • More reliable. No dead batteries, and PoE cameras avoid Wi-Fi congestion entirely.

How to choose

Renting, or want it up this afternoon? Go battery, and add a solar panel. Own your home and want set-and-forget reliability with continuous recording? Wired, ideally PoE, is the stronger long-term choice. Many people mix both: wired at the main entrances, battery for the odd corners.
