Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated upon consolidation. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the consolidated financial statements filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (“Annual Report”). In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive income, stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations or cash flows to be anticipated for the full year 2021 or any future period. The Company has evaluated subsequent events occurring after the date of the condensed consolidated financial statements for events requiring recording or disclosure in the condensed consolidated financial statements. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its significant estimates, including the valuation of accounts receivable, the lives and realization of tangible and intangible assets, contingent consideration liabilities, stock-based compensation expense, customer life, accounting for revenue recognition, contingent liabilities related to legal matters, and income taxes including deferred taxes and valuation allowance. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions it believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could be material to the Company’s financial position and results of operations. The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. Concentrations of Risk Credit Risk – Financial instruments that potentially subject the Company to concentration of credit risk consisted primarily of cash and cash equivalents and accounts receivable from trade customers. The Company maintains its cash deposits at three domestic and two international financial institutions. The Company is exposed to credit risk in the event of default by a financial institution to the extent that cash and cash equivalents are in excess of the amount insured by the Federal Deposit Insurance Corporation. The Company generally places its cash and cash equivalents with high-credit quality financial institutions. To date, the Company has not experienced any losses on its cash and cash equivalents. Concentration of Accounts Receivable and Contract Asset – At March 31, 2021, two customers accounted for 35 % and 29 % of the Company’s total accounts receivable, respectively. At March 31, 2020, one customer accounted for 26 % of the Company’s total accounts receivable. Concentration of Revenues – For the three months ended March 31, 2021, two customers accounted for 34 % and 13 % of the Company’s total revenues, respectively. For the three months ended March 31, 2020, two customers accounted for 19 % and 13 % of the Company’s total revenues, respectively. Concentration of Suppliers – The Company relies on a limited number of suppliers and contract manufacturers. In particular, a single supplier is currently the sole manufacturer of the Company’s proprietary sensors. Accounting Pronouncements Recently Adopted In December 2019, the FASB issued ASU 2019-12 , Income Taxes (Topic 740), simplifying the accounting for income taxes by removing certain exceptions to the general principles. The Company adopted this ASU as of January 1, 2021. The adoption of this ASU did not have any impact on the Company’s condensed consolidated financial statements In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects current expected credit loss (“CECL”) and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted this ASU as of January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements.

Business Combinations [Abstract]
Business Acquisition	Note 4. Business Acquisition LEEDS On November 24, 2020 , the Company completed the acquisition of 100 % of the membership interests in LEEDS, LLC ("LEEDS") for a purchase consideration of $ 21.6 million in cash, subject to working capital adjustments, and $ 2.0 million in 63,901 units of ShotSpotter common stock. The purchase consideration also included a contingent earnout agreement. Up to $ 2.5 million in contingent earnout will be payable based on LEEDS' revenues generated during 2021. An additional amount up to $ 2.5 million contingent earnout will be payable based on LEEDS' revenues during 2022. The amounts will be determined and paid within approximately 90 days after the end of 2021 and 2022, respectively. The preliminary fair value of the contingent earnout is $ 0.2 million, resulting in a total estimated purchase consideration of $ 23.8 million. The acquisition will enable the Company to broaden its suite of precision policing solutions to offer its customers. The following table summarizes the final purchase price allocation (in thousands): Cash and cash equivalents $ 7,044 Accounts receivable and contract asset, net 1,060 Property and equipment, net 161 Operating lease right-of-use asset 225 Goodwill 1,437 Customer relationship 14,410 Other asset 45 Accrued expenses and other current liabilities ( 458 ) Other liabilities ( 98 ) Total purchase consideration $ 23,826 Goodwill primarily represents the value of the employee workforce as well as cash flows from future customers. The Company expects to deduct the amortization of goodwill and intangible assets for tax purposes. A portion of the amortization deduction will commence upon settlement of contingent consideration and contingent liabilities. The Company valued the customer relationship asset using the income approach. Significant assumptions include forecasts of revenues, cost of revenues, research and development expense, sales and marketing expense, general and administrative expense and estimated customer attrition rates. The Company discounted the cash flows at 7 %, reflecting the risk profile of the asset. The customer relationship asset will be amortized over an estimated useful life of 15 years . Acquisition-related expenses totaled $ 0.8 million, $ 0.2 million of which were included in general and administrative expense for the three months ended March 31, 2021. The remaining $ 0.6 million was expensed in 2020.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5. Fair Value Measurements In October 2018, upon the acquisition of certain technology, referred to as HunchLab, from Azavea, Inc., the Company recognized a contingent consideration liability classified within Level III of the fair value hierarchy because some of the inputs used in its measurement were neither directly nor indirectly observable. In January 2020 and February 2021, based on the relevant revenues earned during the second and third year respectively, of the three-year contingent consideration period, the Company paid $ 0.3 million and $ 0.4 million respectively, to Azavea, Inc., resulting in a reduction of the contingent consideration liability. In November 2020, using a Monte Carlo Simulation approach, the Company estimated the fair value of the contingent consideration at the acquisition date of LEEDS to be $ 0.2 million. There have been no changes in the assumptions or fair value of the contingent consideration liability at March 31, 2021. The changes in the fair value of contingent consideration liability for the three months ended March 31, 2021 and 2020 is as follows (in thousands): For the Three Months Ended March 31, 2021 2020 Balance, beginning of period $ 573 $ 750 Payment of contingent consideration liability ( 403 ) ( 347 ) Balance, end of period $ 170 $ 403

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 13. Commitments and Contingencies Contingencies On August 28, 2018, Silvon S. Simmons (the “Plaintiff”) amended a complaint against the City of Rochester, New York and various city employees, filed in the United States District Court, Western District of New York, to add the Company and employees as a defendant. The amended complaint alleges conspiracy to violate plaintiff’s civil rights, denial of the right to a fair trial, and malicious prosecution. The Plaintiff claims that ShotSpotter colluded with the City of Rochester to fabricate and create gunshot alert evidence to secure Plaintiff’s conviction. On the basis of the allegations, the Plaintiff has petitioned for compensatory and punitive damages and other costs and expenses, including attorney’s fees. The Company believes that the Plaintiff’s claims are without merit and is disputing them vigorously. The Company may become subject to legal proceedings, as well as demands and claims that arise in the normal course of business. Such claims, even if not meritorious, could result in the expenditure of significant financial and management resources. The Company makes a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed and adjusted to include the impacts of negotiations, estimated settlements, legal rulings, advice of legal counsel, and other information and events pertaining to a particular matter. An unfavorable outcome on any litigation matters could require payment of substantial damages, or, in connection with any intellectual property infringement claims, could require the Company to pay ongoing royalty payments or could prevent the Company from selling certain of our products. As a result, a settlement of, or an unfavorable outcome on, any of the matters referenced above or other litigation matters could have a material adverse effect on the Company’s business, operating results, financial condition and cash flows. The COVID-19 pandemic has resulted in a substantial curtailment of business activities worldwide and is causing weakened economic conditions, both in the United States and many countries abroad. As part of intensifying efforts to contain the spread of COVID-19, many companies and state, local and foreign governments have imposed restrictions, including shelter-in-place orders and travel bans. While some of these companies and jurisdictions have started to relax such restrictions, in some cases, the restrictions were put back in place after having been lifted. The Company understands that the ongoing COVID-19 pandemic, associated travel restrictions and social distancing requirements may continue to have an adverse impact on its results of operations. While the ultimate economic impact of the COVID-19 pandemic is highly uncertain, the Company expects that its business and results of operations, including its revenues, earnings and cash flows from operations, may be adversely impacted for at least the balance of 2021. The Company may be adversely affected by increasing social unrest, protests against racial inequality, protests against police brutality and movements such as “Defund the Police”. These events may directly or indirectly affect police agency budgets and funding available to current and potential customers. Participants in these events may also attempt to create the perception that the Company’s solutions are contributing to the “problem”, which may adversely affect the Company, its business and results of operations, including its revenues, earnings and cash flows from operations.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated upon consolidation. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the consolidated financial statements filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (“Annual Report”). In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive income, stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations or cash flows to be anticipated for the full year 2021 or any future period. The Company has evaluated subsequent events occurring after the date of the condensed consolidated financial statements for events requiring recording or disclosure in the condensed consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its significant estimates, including the valuation of accounts receivable, the lives and realization of tangible and intangible assets, contingent consideration liabilities, stock-based compensation expense, customer life, accounting for revenue recognition, contingent liabilities related to legal matters, and income taxes including deferred taxes and valuation allowance. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions it believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could be material to the Company’s financial position and results of operations. The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
Concentrations of Risk	Concentrations of Risk Credit Risk – Financial instruments that potentially subject the Company to concentration of credit risk consisted primarily of cash and cash equivalents and accounts receivable from trade customers. The Company maintains its cash deposits at three domestic and two international financial institutions. The Company is exposed to credit risk in the event of default by a financial institution to the extent that cash and cash equivalents are in excess of the amount insured by the Federal Deposit Insurance Corporation. The Company generally places its cash and cash equivalents with high-credit quality financial institutions. To date, the Company has not experienced any losses on its cash and cash equivalents. Concentration of Accounts Receivable and Contract Asset – At March 31, 2021, two customers accounted for 35 % and 29 % of the Company’s total accounts receivable, respectively. At March 31, 2020, one customer accounted for 26 % of the Company’s total accounts receivable. Concentration of Revenues – For the three months ended March 31, 2021, two customers accounted for 34 % and 13 % of the Company’s total revenues, respectively. For the three months ended March 31, 2020, two customers accounted for 19 % and 13 % of the Company’s total revenues, respectively. Concentration of Suppliers – The Company relies on a limited number of suppliers and contract manufacturers. In particular, a single supplier is currently the sole manufacturer of the Company’s proprietary sensors.
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted In December 2019, the FASB issued ASU 2019-12 , Income Taxes (Topic 740), simplifying the accounting for income taxes by removing certain exceptions to the general principles. The Company adopted this ASU as of January 1, 2021. The adoption of this ASU did not have any impact on the Company’s condensed consolidated financial statements In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects current expected credit loss (“CECL”) and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted this ASU as of January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements.
