@netcctv_uk: Regarding Power over Ethernet (PoE) switches versus non-PoE switches, it is important to note that PoE switches adhere to IEEE standards, including 802.3af, 802.3at, and 802.3bt, ensuring safe power delivery upon detection of a compatible device. Conversely, non-PoE switches are limited to data transmission, lacking power supply capabilities and necessitating external power sources for connected devices. Cctv tester netcctv uk network
