With its 24Gbps high-performance switch architecture and 120-watt PoE power budget, the recorded video files from the 8 PoE IP cameras powered by the GSD-1222VHP are saved in the 8-channel NVR systems or surveillance software in the monitoring center for possible backup references.

Ideal PoE Switch for All Enterprises

Providing eight 802.3at PoE+ in-line power interfaces, the GSD-1222VHP can easily build a power that centrally controls IP phone system, IP camera system and wireless AP group for enterprises. Cameras can be installed around the corner in the company or campus for surveillance demands. Without the need for power sockets, the GSD-1222VHP makes the installation of cameras easier and more efficient.
