Explanatory Note

This Amendment No. 12 (this “Amendment”) amends the Schedule 13D initially filed on May 29, 1987 (together, with all amendments thereto, the “Schedule 13D”), relating to the common stock, par value $0.01 per share (the “Common Stock”), of Vicon Industries, Inc. (the “Issuer”).

As discussed in Item 5(e) below, as a result of that certain Stock Purchase Agreement (the “Stock Purchase Agreement”) dated as of November 24, 2015 by and between CBC AMERICAS Corp. (the “Company”) and Shenzhen Infinova Limited, the Reporting Persons (as defined herein) disposed of 543,715 shares of Common Stock, all of the shares of the Issuer they owned. Accordingly, this is the final amendment to the Schedule 13D and constitutes an “exit filing” for the Company and for its parent company, CBC Co., Ltd. (the “Parent” and, together with the Company, the “Reporting Persons”).

Not amended.

Item 4 of this Schedule 13D is amended and supplemented by adding the following:

The closing of the sale of the Shares pursuant to the Stock Purchase Agreement occurred on December 28, 2015 and, as a result of the sale of the Shares, as of the date hereof, the Reporting Persons no longer own any shares of Common Stock.

Item 5 of this Schedule 13D is amended and restated in its entirety as follows:

(a) – (b) As of December 28, 2015, the Reporting Persons no longer beneficially owned any shares of Common Stock.

(c) Except as described in Item 4, the Reporting Persons have not effected any transactions in the Common Stock for the past 60 days.

(d) No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Stock reported herein.

(e) Each of the Reporting Persons ceased to beneficially own more than five percent of the shares of Common Stock as of December 28, 2015. Accordingly, this Amendment constitutes an exit filing for the Reporting Persons.
