Fixed-lens 4MP Ethernet IP cameras provide a set field of view, making them well suited for locations where the camera position and coverage area are already known. Varifocal cameras use an adjustable lens, often with motorized zoom and autofocus, so installers can fine-tune the viewing angle and image framing for changing distances or coverage needs.

Choose a dome 4MP Ethernet IP camera for a low-profile installation, a bullet camera for a more visible, directional view, or a turret camera when you need flexible aiming and a weather-ready design. Consider the mounting surface, viewing direction, exposure to weather or tampering, and whether the camera will use features such as infrared night vision or Power over Ethernet (PoE).

For clear video in changing light, compare 4MP image sensors, true wide dynamic range (WDR), low-light performance, and infrared (IR) night vision, including the intended viewing distance. If nighttime color matters, check for color-at-night imaging with supplemental warm-white lighting, and consider whether a fixed or motorized varifocal lens fits the scene.

Yes, many 4MP Ethernet IP cameras support both local microSD storage and recording to a compatible network video recorder (NVR), giving installers flexibility in system design. Local storage can support standalone recording, while an NVR can centralize video from multiple cameras for monitoring and review.
