The following constitutes Amendment No. 2 to the Schedule 13D filed by the Reporting Persons. This Amendment No. 2 amends the Schedule 13D as specifically set forth below. All other Items are unchanged.

ITEM 5. Interest in Securities of the Issuer.

(a)(1) As of the reporting date, the Reporting Persons may be deemed to be the beneficial owner of an aggregate of 12,994,823 shares of Common Stock, which represents approximately 25.00% of the Common Stock outstanding as of November 15, 2010. The aggregate amount includes: (A) 9,539,199 shares of Common Stock issued to the Fund as stock dividends with regard to Series A Preferred Stock previously owned by the Fund, and (B) 3,455,624 shares of Common Stock issued to the Fund upon exercise of warrants issued in connection with the Fund’s purchase of Series A Preferred Stock.

(b) The Fund, the Managing Member, and the Principals may be deemed to share (with each other and not with any third party) the power to dispose or direct the disposition of the 12,994,823 shares of Common Stock.

(c) On March 22, 2011, the Issuer entered into a Securities Redemption Agreement (the “Redemption Agreement”) with Fund and Centaur Value Fund, LP (together, the “Series A Holders”), pursuant to which Issuer sold to the Series A Holders all of the issued and outstanding membership interests (the “APSG Interests”) in American Physical Security Group, LLC, (“APSG”)a wholly-owned subsidiary of the Issuer. WCOF owned 14,025 shares of Issuer’s Series A Convertible Preferred Stock (the “Series A Preferred Shares”). In exchange for receiving its prorate portion of the APSG Interests, WCOF (i) paid the $935,000 in cash at the closing of the transactions contemplated by the Redemption Agreement and (ii) tendered to Issuer the Series A Preferred Shares, which had an aggregate redemption price of $15,427,500.

In connection with the Redemption Agreement, the Issuer and the Series A Holders entered into that certain Membership Interest Option Agreement (the “Option Agreement”) pursuant to which the Series A Holders granted the Issuer an option (the “Option”) to repurchase the APSG Interests within six (6) months following the closing of the transactions contemplated by the Redemption Agreement at a cash purchase price equal to the sum of (i) $15,525,000, plus (ii) the amount of any net investment made in APSG concurrently with and following the closing of the Redemption Agreement and prior to the closing of the purchase of the APSG membership interests pursuant to exercise of the Option.

The description of the terms of the Redemption Agreement and Option Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Redemption Agreement and Option Agreement, filed as Exhibits 10.1 and 10.2, respectively, to the Form 8-K filed by the Issuer on March 28, 2011, incorporated herein by reference.

The Irrevocable Proxy and Voting Agreement (“Voting Agreement”) dated as of May 22, 2009, between Anthony Piscitelli, the CEO of Issuer, and the Series A Holders terminated pursuant to its own terms upon completion of the redemption of all of the issued and outstanding shares of Series A Preferred Stock subject to the Redemption Agreement. As a result, the Fund no longer shares voting power with regard to 8,047,394 shares of Issuer Common Stock held by Mr. Piscitelli.
