2-Port 10/100/1000T 802.3bt PoE + 2-Port 10/100/1000T 802.3at PoE + 1-Port Gigabit Desktop Switch (120W PoE Budget, BT/Legacy mode support)


Perfectly-integrated Solution for PoE IP Camera and NVR System

The GSD-504UP provides four 802.3at/bt PoE ports for catering to small-scale home and SOHO IP surveillance networks at a lower total cost. The GSD-504UP comes with a high-performance switch architecture and 120-watt PoE power budget. The recorded video files from the 4 PoE IP cameras powered by the GSD-504HP are saved to the 4-channel NVR system.

IP Office Department/Workgroup PoE Switch

To further expand the office premises, the additional telephones required could be installed at less cost via the PoE IP telephony system, better than the traditional circuit wiring telephony system. The GSD-504UP PoE++ Switch helps enterprises to create an integrated data, voice, and powered network. The IEEE 802.3af/at compliant IP phones can be installed without the need of an additional power cable because the power can be provided via the standard Ethernet cable from the connected GSD-504UP. With the GSD-504UP, IP telephony deployment becomes more reliable and cost effective, thus helping enterprises save tremendous cost when upgrading from the traditional telephony system to IP telephony communications infrastructure.
