Item 1. Security and Issuer.

     This statement relates to shares of the common stock, $.01 par value per share (the “Shares”), of Vicon Industries, Inc. (the “Issuer”). The principal executive offices of the Issuer are located at 89 Arkay Drive, Hauppage, New York 11788.

Item 2. Identity and Background.

     (a) - (c)

     This Statement is filed by Henry Partners, L.P. (“Henry”), Matthew Partners, L.P. (“Matthew”), Henry Investment Trust, L.P. (“HIT”) and David W. Wright. Henry and Matthew are private investment funds. HIT is the sole General Partner of each of Henry and Matthew. Mr. Wright is the investment manager of each of Henry and Matthew and is the President of Canine Partners, LLC (“Canine”), the General Partner of HIT. Investment decisions made on behalf of Henry and Matthew are made primarily through their General Partner and Mr. Wright. Each of the foregoing persons is sometimes referred to in this Schedule 13D as a “Reporting Person” and collectively as the “Reporting Persons.” The principal business address of each Reporting Person is 255 South 17th Street, Suite 2608, Philadelphia, PA 19103.

     (d) None of the Reporting Persons has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

     (e) None of the Reporting Persons has, during the last five years, been party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

     (f) Henry and Matthew are Delaware limited partnerships. HIT is a Pennsylvania limited partnership. Canine is a Pennsylvania limited liability company, and David W. Wright is a citizen of the United States.

Item 3. Source and Amount of Funds or Other Consideration.

     The aggregate purchase price of the 143,900 Shares owned by Henry is $674,455, and the aggregate purchase price of the 94,100 Shares owned by Matthew is $430,380. Shares owned by Henry and Matthew were acquired with the funds of each respective partnership.

6

Item 4. Purpose of the Transaction.

     The Reporting Persons purchased the Shares based on the Reporting Persons’ belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons and the availability of Shares at prices that would make the purchase of additional Shares desirable, the Reporting Persons may increase their position in the Issuer through, among other things, the purchase of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

     No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D, except as set forth herein or such as would occur upon completion of any of the actions discussed herein.

     Each of the Reporting Persons intends to review its investment in the Issuer on a continuing basis and to engage in discussions with management and the Board of Directors of the Issuer concerning the business, operations, corporate governance and future plans of the Issuer. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation,

• communicating privately or publicly with other stockholders, the Issuer’s Board of Directors or other persons;

• making proposals or director nominations to the Issuer,

• supporting proposals or director nominations made by other stockholders;

• purchasing additional Shares or selling some or all of their Shares;

• or changing their intention with respect to any and all matters referred to in this Item 4.

     The Reporting Persons believe that the Issuer is retaining an excessive amount of liquidity on its balance sheet for no apparent reason, that its shares are materially undervalued due, at least in part, to this unproductive retention of capital and that shareholder value would be meaningfully enhanced by the immediate initiation of a regular quarterly dividend in a material, not a token, amount.

7

Item 5. Interest in Securities of the Issuer.

     (a)-(b)

     The aggregate percentage of Shares reported owned by each person named herein is based upon 4,480,836 Shares outstanding, which is the total number of Shares outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q for the fiscal quarter ended December 31, 2010.

     As of April 20, 2011, Henry beneficially owned 143,900 Shares, constituting approximately 3.2% of the Shares outstanding, and Matthew beneficially owned 94,100 Shares, constituting approximately 2.1% of the Shares outstanding, for an aggregate ownership of both Henry and Matthew of 238,000 Shares, constituting 5.3% of the Shares outstanding. Mr. Wright, as President of the sole general partner of HIT, which is the sole general partner of each of Henry and Matthew, has the authority to vote and dispose of such Shares.

     (c) None of the Reporting Persons effected any transactions in the Issuer’s Shares during the past sixty 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 proceeds from the sale of, such Shares.

     (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

     Other than as described herein, there are no contracts, arrangements or understandings among the persons named in Item 2, or among the persons named in Item 2 and any other person, with respect to the securities of the Issuer.

Item 7. Material To Be Filed As Exhibits.

1. Joint Filing Agreement.
