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, 2021 (“Annual Report”) filed with the SEC on March 29, 2022. 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 (loss), 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 2022 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 any related valuation allowance. In particular, the Company's contingent consideration liabilities are subject to significant estimates surrounding forecasts of certain revenues and other factors. 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 two domestic and four 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 and other local country government agencies. 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 September 30, 2022, two customers accounted for 26 % and 19 % of the Company’s total accounts receivable and contract asset, respectively. At December 31, 2021, one customer accounted for 65 % of the Company’s total accounts receivable and contract asset. Concentration of Revenues – For the three months ended September 30, 2022, two customers accounted for 26 % and 11 % of the Company’s total revenues, respectively. For the three months ended September 30, 2021, two customers accounted for 26 % and 14 % of the Company’s total revenues, respectively. For the nine months ended September 30, 2022, two customers accounted for 32 % and 10 % of the Company’s total revenues, respectively. For the nine months ended September 30, 2021, two customers accounted for 30 % and 14 % 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.

Business Combinations [Abstract]
Business Acquisition	Note 4. Business Acquisition In October 2021, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts from Customers . ASU 2021-08 aimed to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and the effect of payment terms on subsequent revenue recognized by the acquirer. These amendments were effective prospectively for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company early adopted this ASU effective January 1, 2022 . On January 3, 2022 , the Company completed the acquisition of 100 % of the membership interests in Forensic Logic, LLC (“Forensic Logic”) for purchase consideration of $ 4.9 million in cash, subject to working capital adjustments, and $ 14.3 million in 464,540 shares of ShotSpotter common stock based on the closing price on the date of acquisition. The purchase consideration also included a contingent consideration agreement based on forecasted 2022 and 2023 Forensic Logic revenues. If 2022 Forensic Logic revenues exceed $ 7.0 million, the contingent consideration payable may be $ 3.75 million up to a maximum of $ 9.5 million. An additional amount up to $ 10.5 million in contingent consideration may be payable based on Forensic Logic’s revenues generated during 2023. Any amounts due are payable within approximately 120 days after the end of 2022 and 2023. The estimated fair value of the contingent consideration on the date of acquisition was $ 12.4 million, resulting in a total estimated purchase consideration of $ 31.6 million. The acquisition enabled the Company to broaden its suite of precision-policing solutions and cloud-based investigative platforms to offer its customers. The following table summarizes the assignment of fair value to the identified assets and liabilities recorded as of the acquisition date, January 3, 2022 (in thousands): Cash and cash equivalents $ 303 Accounts receivable and contract asset, net 220 Property and equipment, net 200 Operating lease right-of-use assets 1,893 Software technology 7,140 Tradename 1,000 Customer relationships 8,200 Goodwill 20,355 Other assets 186 Accrued expenses and other current liabilities ( 635 ) Operating lease liabilities ( 1,893 ) Deferred revenue ( 5,382 ) Total estimated consideration $ 31,587 Goodwill primarily represents the value of cash flows from future customers and the employee workforce. 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 liabilities. The Company valued the intangible assets using income-based approaches. Significant assumptions included forecasts of revenues, cost of revenues, research and development expense, sales and marketing expense, general and administrative expense, technology lives, royalty rates, working capital rates, customer attrition rates and other estimates. The Company discounted the cash flows at 24 %, reflecting the risk profile of the assets. Acquisition-related expenses totaled $ 0.6 million, of which $ 0.1 million is included in general and administrative expense for the nine months ended September 30, 2022 and the remainder was incurred during the year ended December 31, 2021. There were no acquisition-related expenses in the three months ended September 30, 2022. The unaudited pro forma combined revenue and net loss have been prepared as if the Company had acquired Forensic Logic on January 1, 2021. The unaudited pro forma financial information has been derived from the consolidated statements of operations of the Company and Forensic Logic for the respective periods. The historical financial information has been adjusted in the unaudited combined pro forma information based upon currently available information and certain estimates and assumptions. The actual effect of the transactions ultimately may differ from the pro forma adjustments included herein. However, management believes that the assumptions used to prepare the pro forma adjustments provide a reasonable basis for presenting the significant effects of the transactions as currently contemplated and that the pro forma adjustments are factually supportable, give appropriate effect to the expected impact of events that are directly attributable to the transactions, and reflect those items expected to have a continuing impact on the Company. The unaudited pro forma financial information is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2021. The unaudited pro forma combined revenue and net loss for the three months ended September 30, 2021 would have been $ 16.3 million and $ 1.7 million, respectively. The unaudited pro forma combined revenue and net loss for the nine months ended September 30, 2021 would have been $ 49.0 million and $ 3.9 million, respectively.

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 February 2021, based on the relevant revenues earned during the three-year contingent consideration period, the Company paid $ 0.4 million, resulting in a reduction of the contingent consideration liability to zero . In November 2020, using a Monte Carlo Simulation approach, the Company estimated the fair value of the contingent consideration liability classified within Level III of the fair value hierarchy at the acquisition date of LEEDS LLC, (“LEEDS”) to be $ 0.2 million. During the fourth quarter of 2021, the fair value of the contingent consideration was increased by $ 1.3 million based upon estimated 2022 revenue targets, representing an adjustment to the most likely outcome expected for the liability. There have been no changes in the assumptions or fair value of the LEEDS contingent consideration liability during the three and nine months ended September 30, 2022. In January 2022, using a Monte Carlo Simulation approach, the Company estimated the fair value of the contingent consideration liability classified within Level III of the fair value hierarchy at the acquisition of Forensic Logic to be $ 12.4 million. During the three and nine months ended September 30, 2022, the fair value of the contingent consideration was decreased by $ 5.4 million and $ 8.8 million, respectively, based upon revised estimated 2022 and 2023 revenue targets due to delays in certain expected contracts by a small number of significant potential customers, representing an adjustment to the most likely outcome expected for the liability. The changes in the fair value of contingent consideration liabilities for the nine months ended September 30 are as follows (in thousands): Nine Months Ended September 30, 2022 2021 Beginning balance $ 1,500 $ 573 Payment of contingent consideration liability — ( 403 ) Acquisition of Forensic Logic (Note 4 - Business Acquisition) 12,400 — Change in fair value of contingent consideration ( 8,842 ) — Ending balance $ 5,058 $ 170 There were no transfers into or out of Level III during the nine months ended September 30, 2022 and 2021. As of September 30, 2022, contingent consideration of $ 1.5 million is included in Accrued expenses and other current liabilities in the condensed consolidated balance sheet as it is forecasted that the achievement of milestones will occur within the next 12 months, and $ 3.6 million is included in Other liabilities in the condensed consolidated balance sheet.

Commitments and Contingencies	Note 14. 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. On October 12, 2021, the Company filed a defamation lawsuit against VICE Media, LLC ("VICE") in Delaware Superior Court. The complaint alleged that VICE intentionally misrepresented court records and targeted ShotSpotter with false accusations in order to cultivate a subversive brand that enables VICE to sell sponsored content to corporate advertisers. The lawsuit was dismissed by the prevailing judge on June 30, 2022, but the Company obtained a retraction from VICE of several false statements following the dismissal. 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.

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, 2021 (“Annual Report”) filed with the SEC on March 29, 2022. 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 (loss), 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 2022 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 any related valuation allowance. In particular, the Company's contingent consideration liabilities are subject to significant estimates surrounding forecasts of certain revenues and other factors. 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 two domestic and four 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 and other local country government agencies. 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 September 30, 2022, two customers accounted for 26 % and 19 % of the Company’s total accounts receivable and contract asset, respectively. At December 31, 2021, one customer accounted for 65 % of the Company’s total accounts receivable and contract asset. Concentration of Revenues – For the three months ended September 30, 2022, two customers accounted for 26 % and 11 % of the Company’s total revenues, respectively. For the three months ended September 30, 2021, two customers accounted for 26 % and 14 % of the Company’s total revenues, respectively. For the nine months ended September 30, 2022, two customers accounted for 32 % and 10 % of the Company’s total revenues, respectively. For the nine months ended September 30, 2021, two customers accounted for 30 % and 14 % 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.
