Fixed-lens 8MP IP cameras use a set field of view, which provides consistent coverage for scenes with a known viewing area and subject distance. Varifocal 8MP IP cameras let installers adjust the viewing angle and magnification, helping frame a specific area and capture more detail on distant subjects without changing the camera position.

8MP IP cameras require a compatible Ethernet network, and many models support Power over Ethernet (PoE) through an active PoE port on a compatible network video recorder (NVR) or switch. Recording can use an NVR for centralized storage, while select cameras support local microSD card recording, with some supporting cards up to 512 GB, and H.265+ encoding can help manage storage use.

8MP IP cameras can connect to a compatible NVR or video management platform over a network, with many models supporting Power over Ethernet (PoE) for combined power and video through one Ethernet cable. For existing surveillance systems, select cameras support ONVIF, while local microSD storage and mobile apps can provide standalone recording and viewing when an NVR is not used.

When comparing 8MP IP cameras, review the image sensor, IR night vision or Color at Night illumination, lens aperture, and stated nighttime viewing range, along with True Wide Dynamic Range (WDR) for scenes with bright and shadowed areas. Compare analytics such as motion, human-body, line-crossing, intrusion, loitering, group detection, tamper alerts, and regions of interest to match the camera with the site’s monitoring needs.
