Business Combinations [Abstract]

Business Combination

On February 16, 2012, the Company completed the acquisition of the video conferencing business of Israel-based VCON Video Conferencing, Ltd. (“VCON”) through an asset purchase agreement. VCON is a pioneer in software based video conferencing solutions with product offerings that include group video conferencing endpoints, desktop video conferencing endpoints, video conferencing infrastructure solutions and software development kits. This acquisition and the combination of streaming and digital signage technologies will provide us with complementary technology opportunities allowing us to enter new growth markets.

Pursuant to the asset purchase agreement, the Company paid initial consideration of $4,632 in cash. This initial consideration is subject to a final working capital adjustment.

The estimated fair values of assets acquired and liabilities assumed are preliminary and are based on the information that was available as of the acquisition date to estimate the fair value of assets acquired and liabilities assumed. The Company believes that such information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed, but the Company is waiting for additional information necessary to finalize those fair values. The measurement period for purchase price allocation ends as soon as information on the facts and circumstances becomes available, but will not exceed twelve months from the date of acquisition. Adjustments in the purchase price allocation may require a recasting of the amounts allocated to intangible assets and possible allocation to goodwill, retroactive to the period in which the acquisition occurred. Therefore, the preliminary measurements of fair value reflected are subject to change and any such changes could be significant.

The preliminary fair value of identified assets and liabilities acquired and goodwill is as follows:



Inventory	$	320
Property and equipment	34
Product warranty liability	(8		)
Tradename	500
Patents and technology	2,300
Proprietary software	500
In-process research and development	200
Goodwill	786
	$	4,632

The Company incurred $44 and $270 towards acquisition related expenses, all of which are categorized under general and administrative expenses in the condensed consolidated statements of operations for the three and nine months ended September 30, 2012, respectively.

Supplemental Pro Forma information


1)	Revenue and net loss from the VCON business from February 16, 2012 to September 30, 2012 was $720 and ($773), respectively.


2)	Revenue and earnings of the combined entity as though the business combination occurred as of January 1, 2011 is as follows:



	Three months ended September 30,				Nine months ended September 30,
	2012		2011		2012		2011
Revenue	$	11,573	$	11,886	$	33,595	$	35,249
Net income	929		3,152		1,913		5,115


3)	There were no material, nonrecurring pro forma adjustments directly attributable to the acquisition included in this supplemental Pro Forma information.

As of September 30, 2012, the total remaining unrecognized compensation cost related to non-vested stock options, net of forfeitures, was approximately $680, which will be recognized over a weighted average period of 2.95 years.

During the three and nine months ended September 30, 2012, we granted 92,000 and 187,000 stock options, respectively. During the three and nine months ended September 30, 2011, we granted 96,611 and 101,611 stock options, respectively. We use judgment in determining the fair value of the share-based payments on the date of grant using an option-pricing model with assumptions regarding a number of highly complex and subjective variables. These variables include the risk-free interest rate of the awards, the expected life of the awards, the expected volatility over the term of the awards, the expected dividends of the awards, and an estimate of the amount of awards that are expected to be forfeited. We use the Black-Scholes option pricing model to determine the fair value of share-based payments granted under ASC Topic 718.

In applying the Black-Scholes methodology to the options granted, the Company used the following assumptions:



	Three months ended September 30,		Nine months ended September 30,
	2012	2011	2012	2011
Risk-free interest rate, average	1.1%	1.4%	1.3%	1.7%

Expected price volatility, average	51.1%	51.9%	51.4%	51.8%
Expected dividend yield	0.0%	0.0%	0.0%	0.0%
Weighted average per share fair value	$2.13	$3.35	$2.19	$3.16

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2012
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s forecasted effective tax rate at September 30, 2012 is 37.7%, a 3.1 percentage-point increase from the 34.6% effective tax rate recorded at December 31, 2011. The increase is primarily attributable to the expiration of the U.S. research and development credit on December 31, 2011. The effective tax rate recorded for the quarter ending September 30, 2012 is 34.6%. The difference between the forecasted effective tax rate and the rate recorded is primarily due to discrete items related to benefit from federal return-to-provision true-up. Accrued liabilities as of September 30, 2012 and December 31, 2011 include accrued income taxes payable of $304 and $300, respectively.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
