If your recorder has no PoE port left, you do not need a bigger recorder to add a camera. Connect a PoE switch to the recorder's network connection or to your network, then plug the new camera into the switch. One network cable then carries power and video to the camera.

These Hikvision switches come in 4, 8, 16 and 24 port sizes. Size the switch for the power budget as well as the port count: each PoE port gives up to 30W, but the total across the switch is lower, so add up what the cameras you plan to connect draw. Our IP camera pages give each model's PoE standard.

The cameras themselves are on our cameras page.
