Hi. I'm a CCTV technician, located in Costa Rica, I have a customer who is using your DVR cards on a PC, unfortunately the Hard Drive die,I already replaced the HD and installed the OS, I just need the drivers and the software for the DG2408HF Cards where can I download the drivers and software ? The problem That I have no one sells o represent your products here in Costa Rica, speaking with the customer just told me someone bring the DVR Cards from China, so I don't know what to do about it.
