With an optional dongle, GV-POS Text Sender allows you to directly connect the GV-DVR System to Windows-based POS devices that can generate TXT, INI or JNL files and POS devices compatible with Internet or OPOS protocols. The POS transaction data is transferred to the GV-DVR System via a RS-232 serial cable or TCP/IP connection. The transaction data will be overlaid on live images or recordings. |
