Agilence, based in Camden, N.J., has raised a $4 million funding round led by Granite Ventures for its "video-based exception reporting," which keeps an eye on employees at retail outlets.

The company's subscription-based service minimizes the revenue loss that retailers experience from theft or error by their own cashiers. The service has two parts, active video recording and post-analysis of the footage and outsourced team.

Next Stage Capital, a previous investor, also participated in the round.
