If you are installing IP camera, a Power over Ethernet (PoE) switch is one of the most important parts of the system. Here is what PoE i, why it matter, and how to choose the right switch. ## What is a PoE switch? A PoE switch delivers **both data and electrical power over a single network cable**. That means each IP camera needs only one cable , no separate power adapter at the camera. This makes installations cleaner, faster and cheaper. ## Why PoE is ideal for CCTV - **One cable per camera** , simpler cabling, fewer points of failure. - **Easier placement** , mount cameras where there is no power outlet. - **Centralised power** , connect the switch to a UPS to keep cameras running during outages. ## Choosing the right PoE switch - **Port count** , match it to your camera count, with room to grow. - **Power budget** , make sure the total wattage covers all camera, especially PTZ or heated models. - **PoE standard** , 802.3af, 802.3at (PoE+) or 802.3bt (PoE++) for high-power devices. - **Outdoor vs indoor** , waterproof switches (like Witek outdoor models) for external installs. ## Get the network right the first time A poorly powered network causes cameras to drop offline.
