Sixteen cameras, a dozen APs, and you're still fighting a PoE budget that caps at 250W. Every time you add a PTZ camera or a dense AP cluster, something drops off the power bus. The DMS-1250-18P stops that. Sixteen 2.5G PoE++ ports with a 370W total budget means every device on the floor gets full power without daisy-chaining injectors or splitting loads across two switches. Two 10G SFP+ uplinks keep your core link from choking when all those cameras start streaming at once. Smart managed out of the box — per-port PoE scheduling, VLANs, QoS — so you're not calling an IT contractor every time the layout shifts
