Passive PoE applies voltage directly to the Ethernet cable without negotiation — it is simpler and lower cost, but \u003cstrong\u003eonly safe to use with devices specifically designed for passive PoE at the correct voltage\u003c\/strong\u003e. Using a passive PoE adapter with an incompatible device can cause damage. The TL-POE4818G is designed for use with TP-Link passive PoE products only.\u003c\/p\u003e\n\n\u003ch3\u003eWhich TP-Link devices are compatible with the TL-POE4818G?\u003c\/h3\u003e\n\u003cp\u003eThe TL-POE4818G is recommended for TP-Link passive PoE products including certain EAP access points, CPE outdoor units, and other TP-Link devices that specify 48V passive PoE input. Check your device's specifications to confirm it requires 48V passive PoE before purchasing. Refer to the datasheet for the full compatible device list.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use this with a standard 802.3af\/at PoE switch?\u003c\/h3\u003e\n\u003cp\u003eNo. The TL-POE4818G is a passive PoE injector — it connects between your non-PoE switch\/router and the powered device. It is not designed to be used in conjunction with an active 802.3af\/at PoE switch port. Connect the LAN port of the adapter to your switch, and the PoE port to your passive PoE device.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it reduce network speed?\u003c\/h3\u003e\n\u003cp\u003eNo. The TL-POE4818G supports full Gigabit (10\/100\/1000Mbps) throughput — there is no speed reduction when powering devices via passive PoE.\u003c\/p\u003e\n\n\u003ch3\u003eCan I mount it on a wall?\u003c\/h3\u003e\n\u003cp\u003eYes. The TL-POE4818G includes wall-mounting brackets for a clean, permanent installation. This is particularly useful when the adapter is installed near a ceiling-mounted access point or in a location where a loose adapter would be impractical.\u003c\/p\u003e","brand":"TP-Link","offers":[{"title":"Default Title","offer_id":44387757195493,"sku":"POE4818G","price":24.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/1554\/1221\/files\/tp-link-omada-poe4818g-48v-18w-passive-poe-adapter.webp?v=1779693351","url":"https:\/\/cctvguru.com.au\/products\/tp-link-tl-poe4818g-48v-passive-poe-gigabit-adapter","provider":"CCTV Guru","version":"1.0","type":"link"}
