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, 2019 (“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 loss, equity statement 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 2020 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, stock-based compensation expense, accounting for revenue recognition, and income taxes. 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. 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 –At June 30, 2020, three customers accounted for 30%, 12% and 10%, respectively, of the Company’s total accounts receivable. At December 31, 2019, one customer accounted for 55% of the Company’s total accounts receivable Concentration of Revenues – For the three months ended June 30, 2020, two customers accounted for 19% and 12%, respectively, of the Company’s total revenues. For the three months ended June 30, 2019, two customers accounted for 20% and 14%, respectively, of the Company’s total revenues. For the six months ended June 30, 2020, two customers accounted for 19% and 13%, respectively, of the Company’s total revenues. For the six months ended June 30, 2019, two customers accounted for 21% and 14%, respectively, of the Company’s total revenues. 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. Recent Accounting Pronouncements Not Yet Effective In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ ASU”) 2019-12 , Income Taxes (Topic 740), simplifying the accounting for income taxes by removing certain exceptions to the general principles. The guidance will be effective at the beginning of the Company’s first quarter of fiscal 2021. Early adoption of the amendments is permitted. 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 guidance will be effective at the beginning of the Company’s first quarter of fiscal 2023. Early adoption of the amendments is permitted. The Company does not expect the adoption of this ASU to have any material impact on its condensed consolidated financial statements.

Leases	Note 11. Leases Operating Lease The Company leases its principal executive offices in Newark, California, under a non-cancelable operating lease that expires in October 2021. This lease does not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the lease does not contain contingent rent provisions or renewal options. This lease includes both lease components (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs), which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Upon adoption of Topic 842 on January 1, 2019, the Company recognized an operating lease right-of-use asset of $0.9 million and a corresponding lease liability of $0.9 million, using a discount rate of 6%, which reflects the Company’s incremental borrowing rate for a similar asset and similar term as of the date of adoption. During the three months ended June 30, 2020, the Company executed a lease agreement for office space in Washington, DC, under a non-cancelable operating lease that expires in November 2025. This lease does not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the lease does not contain contingent rent provisions. The lease contains an option to extend the term for an additional five years subject to certain terms and conditions. This lease includes both lease components (e.g., fixed payments including rent, taxes, parking, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs), which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Upon lease commencement on May 1, 2020, the Company recognized an operating lease right-of-use asset of $0.5 million and a corresponding lease liability of $0.5 million, using a discount rate of 3.85%, which reflects the Company’s incremental borrowing rate for a similar asset and similar term as of the date of commencement. The operating lease cost recognized for the three months ended June 30, 2020 and 2019 was $0.1 million for each period. The operating lease cost recognized for the six months ended June 30, 2020 and 2019 was $0.2 million for each period.

The following is a schedule of future minimum payments under the non-cancelable data center arrangements at June 30, 2020 (in thousands): Data Center Arrangements 2020 (remainder of year) $ 58 2021 117 2022 117 2023 39 Total $ 331 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 are 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 shortly after having been lifted. These factors have negatively impacted the Company’s operations and results of operations for the first two quarters of 2020. The Company expects that the evolving COVID-19 pandemic, associated travel restrictions and social distancing requirements will 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, will be adversely impacted for at least the balance of 2020, including as a result: • Delays in its ability to deploy new “go-live” miles attributable to company policies or customer policies designed to protect employee health and comply with government restrictions; • Greater funding challenges for • Possible disruption to the • P otential d ecrease in productivity of its employees or that of its customers or suppliers due to travel ban s or restrictions , work-from-home o r shelter-in-place policies and orders. 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.

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, 2019 (“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 loss, equity statement 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 2020 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, stock-based compensation expense, accounting for revenue recognition, and income taxes. 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.
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 –At June 30, 2020, three customers accounted for 30%, 12% and 10%, respectively, of the Company’s total accounts receivable. At December 31, 2019, one customer accounted for 55% of the Company’s total accounts receivable Concentration of Revenues – For the three months ended June 30, 2020, two customers accounted for 19% and 12%, respectively, of the Company’s total revenues. For the three months ended June 30, 2019, two customers accounted for 20% and 14%, respectively, of the Company’s total revenues. For the six months ended June 30, 2020, two customers accounted for 19% and 13%, respectively, of the Company’s total revenues. For the six months ended June 30, 2019, two customers accounted for 21% and 14%, respectively, of the Company’s total revenues. 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.
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ ASU”) 2019-12 , Income Taxes (Topic 740), simplifying the accounting for income taxes by removing certain exceptions to the general principles. The guidance will be effective at the beginning of the Company’s first quarter of fiscal 2021. Early adoption of the amendments is permitted. 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 guidance will be effective at the beginning of the Company’s first quarter of fiscal 2023. Early adoption of the amendments is permitted. The Company does not expect the adoption of this ASU to have any material impact on its condensed consolidated financial statements.
