Plan for an Ethernet network connection, a compatible Power over Ethernet (PoE) switch or injector, and Cat 5 or higher cable, with the network sized for the cameras’ video traffic and recording setup. Check each camera’s power class before installation, because some higher-powered outdoor floodlight cameras require PoE++ and a separate injector, while other models may support an alternate AC power connection.

PoE outdoor surveillance cameras carry power and video over one Ethernet cable, which can simplify professional installations and provide a stable network connection for outdoor monitoring. Wi-Fi or plug-in cameras may fit locations without an Ethernet run, but they typically depend on wireless connectivity, an AC outlet, or both, while PoE cameras require a compatible PoE switch or injector.

The video features that usually matter most are resolution for identifying people and vehicles, low-light or infrared night vision for after-dark viewing, and a wide-angle lens for covering larger areas with fewer blind spots. Motion detection, including person, vehicle, animal, or zone-based analytics when available, can help reduce unnecessary alerts and focus attention on relevant activity.

Look for a weather-resistant housing and an ingress protection rating suited to the installation, along with mounting hardware or adjustable mounts that support wall, ceiling, or other placement options. For storage, consider cameras that record to a compatible network video recorder (NVR), onboard microSD card, or supported cloud service, depending on how the system will be managed and reviewed.
