Fixed-lens IP network cameras provide a set viewing angle, making them suitable for areas with a known camera position and coverage requirement. Varifocal cameras let installers adjust the focal length, or “zoom,” to fine-tune the viewing area during installation, which helps when distances, angles, or subject details may vary.

Plan a wired Ethernet connection from each IP network camera to a compatible PoE switch or NVR with active PoE ports, allowing one dedicated cable to carry network data and power. Provide network access for viewing and management, and use a compatible NVR or local microSD storage when recording is required.

IP network cameras can connect to compatible network video recorders (NVRs) over Ethernet, with Power over Ethernet (PoE) providing data and power through one cable on supported installations. Many cameras also support local microSD storage for standalone recording, while ONVIF support and compatible security platforms can help integrate live video, recordings, and camera management into a larger system.

For changing light conditions, compare True Wide Dynamic Range (WDR), low-light sensor performance, infrared night vision, and fixed or motorized varifocal lenses with autofocus. For event detection, compare motion detection, intrusion, line crossing, loitering, group or human-body detection, video tampering alerts, and region-of-interest settings.
