Abstract: A computer-based system and business method for recording vehicle purchase transactions involving sales staff and customers. The method involves, through use of a software-driven program on a PC and corresponding server software operating on a remote server, recording audio and video data using a PC-connected digital video camera and PC-connected microphone, generating transaction-specific data to be saved with the audio and video data, transmitting the transaction-specific data, audio, and video data to a remote server for storage, cataloging, and for later search/retrieval if needed by end users. An improved internet protocol (designated SENIP) is employed for enhanced data security in all client/server data transactions.
