Geovision GV-SD-47 PTZ Power Supply
Overview
The Geovision GV-SD-47 is a dedicated power supply unit engineered to deliver regulated DC power to Geovision IP PTZ camera installations. PTZ cameras—pan-tilt-zoom models with motorized mechanical movement—draw more power than fixed domes or bullets, especially under load (pan/tilt movement, zoom transitions, heater operation in cold climates). This supply ensures stable, clean power to prevent brownout glitches, motor stalls, or image dropout that plague undersized or shared power feeds. Deploy this unit when you're building out a professional surveillance system with multiple PTZ heads or when existing PoE infrastructure cannot reliably handle the peak current draw.
Compatibility
The GV-SD-47 is designed for Geovision IP PTZ camera systems. Confirm exact model compatibility with the camera's manual or datasheet before ordering—PTZ power requirements vary by pan/tilt speed, zoom range, and environmental load (heated housings draw additional watts). Compatible families typically include Geovision PTZ models in the GV-PTZ, GV-EBDP, and GV-TBLP series. Do not assume backward or forward compatibility across series without verification.
Installation Notes
Wire the supply according to local electrical code and the camera manufacturer's wiring diagram. Ensure the power supply is mounted in a weatherproof, accessible enclosure if installed outdoors or in damp environments—the supply itself may not be rated for direct moisture exposure. Use appropriate gauge cabling for the run distance to the camera; voltage drop over long cable runs can degrade PTZ performance. Ground the supply frame per local safety standards. Test output voltage under load (camera powered on, executing pan/tilt commands) to verify no sag below the camera's minimum operating threshold.
