Fixed-lens 8MP outdoor security cameras use a set viewing angle, so installers need to plan mounting height, distance, and scene coverage before installation. Motorized varifocal cameras let technicians adjust the focal length and, on supported models, focus remotely after mounting, which helps accommodate changing coverage needs or longer viewing distances.

8MP outdoor security cameras may use infrared (IR) night vision to capture black-and-white video in dark areas, while some models use warm-white supplemental lighting to produce color video at night. Options can also include low-light image sensors, wide dynamic range (WDR), and motorized varifocal lenses to help maintain scene detail as lighting conditions change.

Look for an outdoor-rated enclosure with an ingress protection rating, such as IP65 or IP67, to help guard the camera against rain, dust, debris, and other weather conditions. If the installation faces potential physical contact or vandalism, consider an impact-resistance rating, such as IK04, along with a mounting location and housing suited to the site.

8MP outdoor security cameras commonly connect to a network video recorder (NVR) over Ethernet, using compatible network protocols such as ONVIF for video and event integration. Many models also support microSD card recording for local storage and Power over Ethernet (PoE), which carries power and data through one Ethernet cable when connected to an active PoE port or compatible PoE switch.
