Direct answer
Wired Power over Ethernet cameras are usually preferred for permanent, continuous surveillance because one cable can provide dependable data and power. They avoid battery replacement and reduce dependence on crowded Wi-Fi. Their tradeoffs are cabling cost, installation access, and the need for a suitable switch or recorder.
Wireless cameras are easier to add in difficult retrofit locations, but many still need local power. Battery models often conserve energy by recording events rather than continuous video, which can create gaps depending on detection. Wi-Fi quality, interference, cloud service, battery life, and temperature exposure also matter. A hybrid system is often appropriate: wired cameras at critical entrances, driveways, and long-term locations; wireless units only where cabling is impractical. Compare resolution, low-light performance, lens, storage, analytics, security, and outage behavior before choosing by brand.
