Four-megapixel standard IR IP cameras typically connect to an existing Ethernet network, with many wired models using Power over Ethernet (PoE) for both data and power, while select models support Wi-Fi. They can send video to compatible network video recorders (NVRs) or video management platforms through supported IP and ONVIF connections, and some models also provide local microSD storage for standalone recording or added redundancy.

Many four-megapixel standard IR IP cameras support Power over Ethernet (PoE), allowing a single Ethernet cable to carry power and network data from a compatible PoE switch or NVR. Wi-Fi versions require local power and a 2.4 GHz wireless network, while installers should confirm that the network equipment supports the camera and its video traffic.

Fixed-lens four-megapixel standard IR IP cameras provide a set viewing angle and can simplify placement for consistent indoor or outdoor coverage when the scene is already defined. Varifocal cameras let installers adjust the focal length and framing during setup, making them useful for changing surveillance views or locations that need more flexibility, while outdoor installations should use a camera with a stated weather-resistance rating.

Compare the stated infrared night-vision distance, whether the camera uses True WDR or DWDR, and how each feature supports detail in low-light or high-contrast scenes. For local storage and weather protection, review microSD capacity, standalone or NVR recording options, the published ingress rating, and whether the camera is intended for indoor, covered outdoor, or exposed outdoor installation.
