Every week a homeowner asks us whether they should just buy battery cameras instead of running wires. It is a fair question — wireless cameras are cheaper upfront and install in minutes. Here is the honest comparison from a team that installs both.

The short answer

For cameras you actually depend on, we recommend wired PoE (Power over Ethernet). Wireless cameras have real uses, but reliability, video quality, and long-term cost favor wired for primary coverage.

How each type works

Wired PoE cameras get power and data through a single Ethernet cable back to a recorder. No batteries, no WiFi dependency, continuous recording.

Wireless cameras connect over WiFi and run on batteries or a nearby outlet. Footage typically uploads to the cloud as short event clips.

Reliability: where wired pulls ahead

WiFi congestion. A camera streaming video is one of the heaviest devices on a home network. Add three or four and your WiFi feels it — especially in smart homes already running dozens of devices.
Wall materials. Brick, stone, and stucco exteriors around North Atlanta attenuate WiFi signal badly. The camera mounted outside is on the wrong side of exactly the walls that block signal best.
Batteries. Georgia summers are hard on battery chemistry. Expect recharge trips every few weeks for busy cameras — most homeowners quietly stop maintaining them within a year.
Recording gaps. Battery cameras wake on motion, which means the seconds before an event are often missing. Wired cameras record continuously, so the full approach is on footage, not just the moment someone reaches the porch.

Cost: cheaper upfront is not cheaper overall

A quality wireless camera runs $100–$250 plus a cloud subscription per camera, forever. Our wired installs run about $450 per camera all-in — camera, wiring, recorder configuration, and tuning — with local recording and no mandatory subscription. Over five years, a four-camera wireless setup with cloud plans usually costs more than the wired system, and delivers less.

Where wireless genuinely makes sense

Rentals and short-term situations where you cannot run cable.
Detached areas beyond practical wiring reach — though a wired bridge is often possible.
Temporary monitoring — a construction phase, a vacation rental turnover, a problem corner you are evaluating.

Integration matters too

Wired systems integrate cleanly with the rest of a smart home: validated events can trigger lighting scenes, notifications route through one app, and footage stays on your recorder rather than a third-party cloud. That is harder — sometimes impossible — with subscription-locked wireless ecosystems.

Our recommendation

Wire the cameras that protect entry points and driveways. Use wireless only where wiring truly is not practical. If you are weighing options for your property, StarlightATL does free consultations across Metro Atlanta and will tell you plainly which locations justify wiring and which do not.
