Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets represent items to be used as a tax deduction or credit in future tax returns for which a tax benefit has been recorded in the income statement. The Company has a valuation allowance against its deferred tax assets due to the uncertainty of future realization. The full valuation allowance is determined to be appropriate due to the Company's operating losses since fiscal year 2010 and the inherent uncertainties of predicting future operating results in periods over which such net tax differences become deductible. At December 31, 2017, the Company had, as adjusted for the Tax Act (see below), approximately $11.5 million of unrecognized net deferred tax assets available, which includes approximately $7.7 million of tax effected U.S. and foreign net operating loss carryforwards. On August 29, 2014, the Company merged with IQinVision, Inc. In connection with this merger, the Company's ability to utilize pre-merger net operating losses and tax credit carryforwards in the future is subject to certain limitations pursuant to Section 382 of the Internal Revenue Code. The annual limitation on utilization of the Company's U.S. net operating loss carryforwards is presently estimated at $500,000. On November 7, 2017 the Company completed a rights offering that could further limit its ability to utilize prior net operating losses and tax credit carryforwards in the future pursuant to Section 382 of the Internal Revenue Code. This will not materially impact the balance sheet or statement of operations as all deferred tax assets have a full valuation allowance. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cut and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code that affects 2017. The Tax Act also establishes new tax laws that will affect 2018 and after, including a reduction in the U.S. federal corporate income tax rate from 34% to 21%. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements.
