The GV-Control Center provides the security service department with one point of control to all the networked GV-Systems and I/O devices. It features remote DVR configuration, matrix view, remote ViewLog, I/O Central Panel, and Remote Desktop.

The GV-Central Monitoring Station includes GV-Center V2 Pro, GV-Center V2, GV-VSM, GV-Dispatch Server, and GV-Control Center modules. The GV-Central Monitoring Station is an extremely powerful and cost effective central station solution that can efficiently manage multiple GV-System servers from one point of control.

The GV-Center V2 Pro is a professional version of software that brings multiple GeoVision GV systems together into an integrated interface, allowing the operator to view live video images from maximal 800 channels at its multi-functional monitoring screen.

Compared to the professional version of GV-Center V2 Pro software, GV-Center V2 is a free standard version that comes with the installation CD of GV-Series software, allowing the operator to view live video images from maximal 80 channels at its multi-functional monitoring screen.

The GV-Dispatch Server utilizes load-balancing technique to distribute the network load between online and offline GV-Center V2 servers, allowing requests from up to 25,000 GV-Systems to be evenly distributed across maximal 500 GV-Center V2 servers.

The GV-VSM is event-alert text messages service that activates when any online GV-System is event-triggered, and helps IT operators easily notice GV-Systems health status and response instantly to various frequent events.
