Starlight image sensors help four-megapixel IP cameras adapt to changing ambient light, producing more detailed color video with improved clarity in low-light conditions. This helps preserve useful nighttime scene detail while maintaining the camera’s four-megapixel resolution.

Choose a motorized varifocal lens, typically around 2.8 to 12 mm, when you need adjustable framing and focus during installation, with dome, bullet, and turret form factors suited to different mounting locations. Choose a fixed 2.8 mm dome for a compact, wide-area view, or a PTZ form factor with optical zoom when the installation requires remote pan, tilt, and long-distance detail.

Four-megapixel starlight IP cameras typically require an Ethernet network connection to a compatible switch, network video recorder (NVR), or video management system, with Power over Ethernet (PoE) available on supported models. Recording can use an NVR or local microSD storage on models that support it, while required network capacity and storage depend on camera settings, the number of cameras, and retention needs.

Four-megapixel starlight IP cameras can connect to compatible network video recorders (NVRs) or video management systems over Ethernet, with ONVIF support helping integrate video, edge storage, and related control functions. Depending on the camera and system, installers can also use Power over Ethernet (PoE), onboard microSD recording, and supported smart home platforms for live viewing, playback, alerts, and camera control.
