Connect Gates Recommendation:
• Connect Gates recommends the D-Link DGS-1250 Series for projects that need Smart Managed Gigabit switches with 10G SFP+ uplinks and advanced network control.
• For CCTV projects, the PoE models are suitable for powering IP cameras, access points, and VoIP phones while using Surveillance Mode to organize camera traffic.
• For structured cabling or data-only projects, the non-PoE models are suitable when devices are powered separately and high port density is required.
• For proper design, Connect Gates recommends selecting the model based on number of ports, PoE requirement, PoE power budget, uplink design, VLAN plan, and network management requirements.
