This recorder does not include built-in PoE camera ports and requires an external PoE switch.\u003cbr\u003e\n16CH\u003cbr\u003e\nIP Camera Input\u003cbr\u003e\nNo PoE\u003cbr\u003e\nExternal Switch Required\u003cbr\u003e\n320Mbps\u003cbr\u003e\nIncoming Bandwidth\u003cbr\u003e\n2 Bays\u003cbr\u003e\nSATA Storage\u003cbr\u003e\n4K\u003cbr\u003e\nHDMI Output\u003cbr\u003e\nImportant PoE Notice\u003cbr\u003e\n      The NVR502-16B does not have built-in PoE ports. IP cameras must be connected through a separate PoE switch, network switch with PoE, PoE injectors, fiber uplinks, or other properly designed network infrastructure. Confirm total camera bitrate, PoE power budget, switch uplink capacity, VLAN design, and network topology before ordering.\u003cbr\u003e\nFlexible Recorder for Structured Network Deployments\u003cbr\u003e\n      Because this model does not include built-in PoE, it is especially suitable for systems where cameras connect through managed PoE switches, multiple network closets, fiber uplinks, VLANs, or an existing enterprise network. This design gives installers greater flexibility than a recorder with fixed onboard PoE ports.\u003cbr\u003e\nKey Features\u003cbr\u003e\n16-Channel IP Recording\u003cbr\u003e\nSupports up to 16 IP camera channels for professional surveillance systems.\u003cbr\u003e\nExternal PoE Switch Required\u003cbr\u003e\nThis model has no built-in PoE camera ports.
