Power over Ethernet (PoE) carries power and network data over one Ethernet cable, which can reduce wiring and simplify placement for indoor, outdoor, and ceiling-mounted cameras. Connect the camera to a compatible PoE switch or injector, then manage its network connection through the surveillance system without running a separate power cable to each camera.

Dome cameras use a low-profile, often ceiling-mounted housing for discreet indoor coverage, while bullet cameras use a longer housing suited to directional indoor or outdoor views, and turret cameras offer a compact, weatherproof design for exposed outdoor installations. Flexible cameras support table or ceiling mounting in adaptable locations, while pan-tilt-zoom cameras add remote pan, tilt, and zoom control for adjusting the viewing direction.

Compare 2K (4MP) cameras for general surveillance coverage and 4K (8MP) cameras when finer image detail supports the project. Field of view options include fixed wide-angle views around 102.4 or 120.6 degrees, while PTZ cameras offer adjustable views from about 99.7 to 45.5 degrees, with 2x or 3x optical zoom for closer views.

Infrared night vision helps cameras capture footage in low-light or dark areas, while select PTZ models add integrated white LED lighting to support visibility and color night vision. Smart event detection on supported cameras can identify people, vehicles, and animals, helping installers and operators focus on relevant activity as lighting and scene conditions change.
