4-Port Gigabit PoE BT Switch 1 RJ45 + 1 SFP Uplink 802.3bt 70W myhopshun
Product Description
Why Choose a Full Gigabit PoE BT Switch?
In modern IP surveillance and wireless networks, standard PoE switches often cannot power high-demand devices such as PTZ speed domes, 802.11ax APs, or conference tablets. This 4-port Gigabit PoE BT switch solves that problem by supporting the latest IEEE 802.3bt standard, delivering up to 70W per port — enough for the most power-hungry PoE devices.
