Short answer
Battery cameras go almost anywhere without an outlet but need recharging and often record short motion clips to save power; wired cameras can record continuously as long as their power source or backup holds, but need a cable run to each spot. Many properties end up hybrid: wired where power is near and the view matters most, battery for the odd corner.

What is the difference between battery and wired security cameras?
A battery-powered camera runs on a battery, so it can be mounted almost anywhere without an electrical connection nearby; battery type, runtime, and maintenance depend on the model and conditions. A wired camera draws continuous power through a cable to an outlet or recorder, so it needs a working power source or suitable backup instead of recharging.
That freedom is what a battery camera costs the homeowner in upkeep: the battery has to be recharged or swapped on a schedule that depends on how much motion the camera records, how cold it gets, and how far it sits from a charging point. A wired camera has no recharge schedule — once the cable is run, the power side comes down to keeping the outlet or recorder powered, ideally with backup for outages.
Video behavior follows the same split. A wired camera can typically record continuously at full resolution without draining a battery. A battery camera usually conserves power by recording in short clips triggered by motion rather than a constant feed, which keeps runtime reasonable but means it isn't watching every second the way a wired camera can.
Which is more reliable, battery or wired power?
Wired cameras are generally better suited to continuous recording since they draw steady power and don't need a scheduled recharge, though they still depend on mains power or suitable backup. Battery-powered cameras add a maintenance cycle — a battery that runs down before it's recharged means no recording until it's changed, and busy spots drain it faster than quiet ones.
Cold weather is the variable that catches people off guard. Battery performance drops in low temperatures, so a camera that lasted a long time between charges over the summer can need recharging much more often once winter sets in. Wired cameras aren't immune to failure either, but the failure point moves from the camera's battery to the property's electricity, which is why a wired setup is usually paired with professional installation that accounts for backup power at the recorder.
Connectivity is a separate question from power, and the two get confused often. A camera can be battery-powered and still transmit over Wi-Fi, or wired for power and cellular for signal. For a closer look at how connection type affects reliability on its own, see this comparison of wired and wireless security cameras.
How do battery and wired cameras compare on cost?
A battery camera usually costs less to install since there's no cable run, but it adds an ongoing task of recharging or replacing batteries for as long as the camera stays in service. A wired camera costs more upfront in labor to run cable and mount a recorder, but little recurring after that beyond electricity and any backup-power upkeep.
That upfront gap is mostly labor. Running cable through walls or an attic to a central recorder takes longer and is best handled professionally, which adds to the initial bill. A battery camera typically mounts with a few screws and pairs to an app, so the install cost stays low — the cost just shows up later, in ladder trips and battery replacements instead of a one-time cable run.
When does a hybrid setup make more sense?
A hybrid setup puts battery cameras where running a cable is impractical — a shed, a fence line, a rental unit — and wired cameras at fixed, high-priority points like an entry door or driveway where continuous power matters most. It costs more to plan than either option alone, but it avoids compromising coverage at either type of location.
A common layout runs a wired camera at the front door and driveway, where footage matters most and a cable run is straightforward, while battery units cover spots that would otherwise need an expensive trench or conduit run. The tradeoff is upkeep: every battery camera added to the layout is one more recharge schedule to track, so most properties keep the battery count low and reserve it for locations where a cable genuinely isn't an option.
