Geovision GV-COM PTZ Camera Setup

Geovision GV-COMThe Geovision GV-COM module can be used with a Geovision camera system to control PTZ cameras.  These setup instructions cover how to setup our PTZ security camera to be controlled by one of our GV-COM modules.  The GVCOM module has RS-485 inputs that are used to connect your PTZ cameras to Geovision.  RS-485 is a communication protocol for cameras and other decives. If you are using a PTZ camera other than the one that we have documented in this article, you can still follow the steps of these instructions but the protocol and baud rate that you configure may be different depending on the type of PTZ camera that you are using and the baud settings that are supported by your particular PTZ camera. 

PTZ Camera Setup

First, follow these instructions to setup the PTZ camera.  This link will open up a new browser window so that you can easily resume instructions on this page after the camera in configured.

Geovision GV-COM Installation

These instructions assume that you are setting up camera ID #1 or that you are only using one PTZ camera in your system.  If you are setting up more than one camera, the ID that you configure may not be 001 as described below. The Geovision GV-COM module is easy to install with your computer.  The card simply connects to any open USB port and some software drivers need to be installed that afre included on a CD with your GVCOM device.

  1. Connect one end of the RS 485 wire (one end should already be connected to you PTZ camera) to the RS-485 +/- inputs on the GV-COM module.  The small plastic green housing of the RS-485 inputs on the GV-COM  can be removed to more easily let you install and screw down your wiring.  You can see this below.

  2. Insert the RS-485 connector back into the GV-COM device if you removed it to install the wiring.  This should look similar to below when done.
