Using GV-POS S/W Capture, you can directly connect a Windows-based POS device, generating EMF files or any other raw (unprocessed) data, to GV-DVR / NVR / VMS. The transaction data of the POS device can be transferred to the GV-DVR / NVR / VMS via a RS-232 serial cable or TCP/IP connection to be overlaid onto camera live view and recordings.
