Wired indoor security cameras use a cable for power, data, or both, which can support consistent operation and integration with a network video recorder. Wi-Fi cameras send video over a wireless network but commonly use an outlet, while battery-powered cameras reduce cabling and offer more flexible placement, though they require periodic recharging.

Look for at least 1080p video for general room monitoring, with 2K, 1440p, or 4K options providing more detail for wider views or digital zoom. For nighttime coverage, consider infrared night vision for dark rooms, color night vision or low-light imaging for added detail, and wide dynamic range or HDR to help balance bright and shadowed areas.

Indoor security cameras may connect to video recorders through an IP network, with some wired models supporting Power over Ethernet (PoE) and many cameras storing video on a local microSD card or compatible network video recorder (NVR). Wi-Fi or wired network connections can also link cameras with compatible smart home platforms and mobile apps for live viewing, recorded video, motion notifications, and camera controls.

Indoor security cameras can sit on a table or flat surface, or mount to a wall, ceiling, beam, or other suitable location, depending on the camera design. Fixed dome and turret cameras provide a set viewing angle, while pan-tilt models let users adjust the view remotely through a mobile app for broader room coverage.
