IP dome cameras typically connect to a compatible network video recorder (NVR) with a Category cable through an available Power over Ethernet (PoE) port, which carries video, data, and power over one cable. If the NVR does not provide PoE, connect the cameras through a PoE network switch and link that switch to the NVR, or use a separate power source where supported.

Check that the NVR supports ONVIF devices, the camera’s video resolution, and its encoding formats, such as H.265, H.264, or MJPEG. If you plan to power cameras through the NVR, also verify that it has compatible Power over Ethernet (PoE) ports, enough channels, and support for the camera’s recording and analytics features.

Fixed-lens IP dome cameras provide a set viewing angle, making them a straightforward choice when the coverage area and camera position are already known. Varifocal IP dome cameras allow installers to adjust the focal length and framing, which can help fine-tune coverage during installation or accommodate changing surveillance needs, while both camera types can connect to a compatible NVR through network connectivity.

IP dome cameras with 4MP to 8MP resolution, wide dynamic range, infrared night vision, and low-light imaging technologies can help produce clear video in varied lighting. For efficient NVR recording, look for models with H.265 or H.265+ encoding, Power over Ethernet (PoE), and ONVIF support, while confirming compatibility with the selected NVR.
