How to Emulate Geovision USB Dongle for Control Center
Geovision USB dongle is a device that allows you to use Geovision software such as Control Center, which is a remote management tool for Geovision surveillance systems. The dongle contains a license key that enables you to connect to multiple Geovision devices and access their features. However, if you lose or damage your dongle, or if you want to use the software on another computer without the dongle, you may need to emulate it.
Emulating Geovision USB dongle is not an easy task, as it requires reverse engineering skills and tools. However, some people have claimed to have successfully done it and shared their methods online. In this article, we will summarize some of the steps that have been posted on various forums and websites. However, we do not guarantee that these methods will work for you, nor do we endorse or support them. Emulating Geovision USB dongle may violate Geovision's terms of service and warranty, and may expose your system to security risks. Therefore, proceed at your own risk and responsibility.
Step 1: Identify your dongle type
Geovision uses different types of USB dongles for different software versions and products. You need to identify your dongle type before you can emulate it. To do this, you can use a tool called GVUsbKeyUpClient.exe, which is available from Geovision's website[^1^]. This tool can show you the information of your dongle, such as its serial number, product name, version number, and supported features. You can also use this tool to export the data from your dongle and save it as a *.out file.
Alternatively, you can use a device manager or a USB analyzer tool to check the vendor ID (VID) and product ID (PID) of your dongle. These are hexadecimal numbers that identify the manufacturer and model of your USB device. For example, according to one forum post[^2^], Geovision uses VID_04B4 and PID_2000 or PID_2007 or PID_1BEC for its USB dongles.
Step 2: Dump your dongle data
Once you know your dongle type, you need to dump its data into a file that can be used for emulation. There are different tools and methods for doing this, depending on the type of dongle you have. For example, if you have a Hardlock dongle[^2^], you can use a tool called hl-dump.exe to dump its memory into a *.dmp file. If you have another type of dongle, you may need to use a USB sniffer or a debugger to capture its communication with the software.
The goal of this step is to obtain a file that contains the license key and other information that the software needs to verify the presence of the dongle. This file should be in a format that can be recognized by an emulator program.
Step 3: Emulate your dongle
The final step is to emulate your dongle using an emulator program that can create a virtual USB device on your computer. The emulator program should be able to load the file that you obtained in step 2 and simulate the behavior of your dongle. For example, if you have a Hardlock dongle[^2^], you can use a program called MultiKey.exe to emulate it. If you have another type of dongle, you may need to find or create an emulator program that supports it.
The emulator program should run in the background and intercept the requests from the software to the dongle. It should respond with the appropriate data from the file that you loaded. This way, the software will think that the dongle is connected and will allow you to use its features.
In this article, we have briefly described how to emulate Geovision USB dongle for Control Center. However, this is not a comprehensive guide, nor a reliable solution. Emulating Geovision USB dongle may not work for all types of dongles or software versions. It may also cause errors or malfunctions in your system. Moreover, it may violate Geovision's terms of service and warranty 061ffe29dd
