Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	NOTE 3: - SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies applied in the annual consolidated financial statements of the Company as disclosed in the Company's Annual Report on Form 20-F for the period ended December 31, 2018 filed with the SEC on April 18, 2019, are applied consistently in these unaudited interim consolidated financial statements, except for: a. Short-term bank deposits: Bank deposits with maturities of more than three months at acquisition but less than one year are included in short-term bank deposits. Such deposits are stated at cost which approximates their fair values. b. Adoption of new accounting principles: In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02 (Topic 842) "Leases". The standard supersedes the lease requirements in Accounting Standards Codification ("ASC") Topic 840, "Leases". Under ASC 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. The Company adopted ASC 842 on January 1, 2019 , . Operating leases are included in operating lease ROU assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of the lease payments. Operating lease expenses are recognized on a straight-line basis over the lease term. Several of the Company's leases include options to extend the lease and some have termination options that are factored into the Company's determination of the lease payments when appropriate. For purposes of calculating lease liabilities, lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company's lease agreements do not contain any material residual value guarantees. A portion of the Company's real estate leases is generally subject to annual changes in the Consumer Price Index ("CPI"). The changes to the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. For all short-term leases which are less than 12 months and existing short-term leases of those assets in transition, the Company does not recognize operating lease ROU assets or operating lease liabilities, but recognizes lease expenses over the lease term on a straight-line basis. As a result of the adoption of ASC 842 on January 1, 2019, the Company recorded both operating lease ROU assets and operating lease liabilities of $5,936 c. New accounting standards not yet effective In January 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses on Financial Instruments", which requires that expected credit losses related to financial assets measured on an amortized cost basis and available for sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available for sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The new standard will be effective for interim and annual periods beginning after January 1, 2020, and early adoption is permitted. The Company is currently evaluating the potential effect of this standard on its consolidated financial statements.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 7: - COMMITMENTS AND CONTINGENCIES a. Royalty commitments: 1. The Company receives research and development grants from the Israel Innovation Authority (the "IIA"). In consideration for the research and development grants received from the IIA, the Company has undertaken to pay royalties as a percentage of revenues from products developed from research and development projects financed. If the Company does not generate sales of products developed with funds provided by the IIA, the Company is not obligated to pay royalties or repay the grants. Royalties are payable at the rate of 3% from the time of commencement of sales of all of the Company's products until the cumulative amount of the royalties paid equals 100% of the dollar-linked amounts of the grants received, plus interest at LIBOR. As of June 30, 2019, the Company's total commitment with respect to royalty-bearing participation received or accrued, net of royalties paid or accrued, amounted to $49,601. Royalty expenses relating to the IIA grants included in cost of revenues during the six month periods ended June 30, 2019 and 2018 were $438 and $646, respectively. In May 2010, the Company received a notice from the IIA regarding alleged miscalculations of the amount of royalties paid by the Company to the IIA for the years 1992-2009 and the revenues basis on which the Company had to pay royalties. The Company believes that all royalties due to the IIA from the sale of products developed with funding provided by the IIA during such years were properly paid or were otherwise accrued. The Company reviewed with the IIA the alleged miscalculations. The Company assessed the merits of the aforesaid arguments raised by the IIA and recorded a liability for an estimated loss. 2. In April 2012 and in April 2014, the Israeli Ministry of Economy ("MOE") approved the Company's application for participation in funding the setting up of the Company's India subsidiary and China branch as part of a designated grants plan for setting up and establishing a marketing agency in India and China. The grant is intended to cover up to 50% from the costs of the office establishment, logistics expenses and hiring employees and consultants in India and China, based on the approved budget for the plan over a period of three years. The Company is currently in the process of winding down its operations at the China office. The total marketing grants that the Company had received from the MOE as of December 31, 2017 were in the amount of $668. No further grants are expected to be received from such plans. The Company is obligated to pay to the MOE royalties of 3% on the increased sales in the target market, with respect to the year during which the grant was approved over a period of five years but not more than the total linked amount of the grant received. As of June 30, 2019, the Company paid an aggregate amount of $9 of royalties to the MOE. 3. According to the Company's agreements with the Israel-U.S Bi-National Industrial Research and Development Foundation ("BIRD-F"), the Company is required to pay royalties at a rate of 5% of sales of products developed with funds provided by the BIRD-F, up to an amount equal to 150% of the BIRD-F's grant, linked to the United States CPI relating to such products. The last funds from the BIRD-F were received in 1996. In the event the Company does not generate sales of products developed with funds provided by the BIRD-F, the Company is not obligated to pay royalties or repay the grants. The total research and development funds that the Company has received from the BIRD-F were $340 (CPI linked amount of $576). According to the above, as of June 30, 2019, the total royalties commitment the Company may be required to pay is an amount of up to $864 out of which $476 was paid by the Company in previous years. The remaining commitment with respect to royalty-bearing participation received, net of royalties paid or accrued, amounted to $388 as of June 30, 2019. Since 2003, the Company has not generated sales of products developed with the funds provided by the BIRD-F. Therefore, the Company has not been obligated to pay royalties or repay the grant since such date. b. From time to time, the Company may be involved in various claims and legal proceedings. The Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. The Company's estimations and related accruals, if any, are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events relating to a particular matter.

Accounting Policies [Abstract]
Short-term bank deposit	a. Short-term bank deposits: Bank deposits with maturities of more than three months at acquisition but less than one year are included in short-term bank deposits. Such deposits are stated at cost which approximates their fair values.
Adoption of new accounting principles	b. Adoption of new accounting principles: In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02 (Topic 842) "Leases". The standard supersedes the lease requirements in Accounting Standards Codification ("ASC") Topic 840, "Leases". Under ASC 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. The Company adopted ASC 842 on January 1, 2019 , . Operating leases are included in operating lease ROU assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of the lease payments. Operating lease expenses are recognized on a straight-line basis over the lease term. Several of the Company's leases include options to extend the lease and some have termination options that are factored into the Company's determination of the lease payments when appropriate. For purposes of calculating lease liabilities, lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company's lease agreements do not contain any material residual value guarantees. A portion of the Company's real estate leases is generally subject to annual changes in the Consumer Price Index ("CPI"). The changes to the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. For all short-term leases which are less than 12 months and existing short-term leases of those assets in transition, the Company does not recognize operating lease ROU assets or operating lease liabilities, but recognizes lease expenses over the lease term on a straight-line basis. As a result of the adoption of ASC 842 on January 1, 2019, the Company recorded both operating lease ROU assets and operating lease liabilities of $5,936
New accounting standards not yet effective	c. New accounting standards not yet effective In January 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses on Financial Instruments", which requires that expected credit losses related to financial assets measured on an amortized cost basis and available for sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available for sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The new standard will be effective for interim and annual periods beginning after January 1, 2020, and early adoption is permitted. The Company is currently evaluating the potential effect of this standard on its consolidated financial statements.
