Over the last decade, surveillance technology has evolved rapidly, transforming how information is gathered and assessed by both the government and the private sector. From facial recognition software to the expansion of data analytics, these technologies have become central to a broader debate about security, privacy, and accountability. According to a 2022 Statista report, the global market for video surveillance technology was valued at more than 50 billion U.S. dollars, indicating a consistent increase in demand for sophisticated monitoring devices across governments and sectors. The argument is no longer purely political: private investigators and corporate security agencies now face similar dilemmas and opportunities.
In this context, investigative departments have found themselves adapting their methods to balance efficiency with compliance. Old-fashioned surveillance relied primarily on field observation, physical surveillance, and photography. Although these techniques are still utilized, contemporary investigations increasingly demand the inclusion of technology. Facial recognition software, for instance, is now used by law enforcement and licensed private investigators to sift through identities in large datasets. Nevertheless, concerns about accuracy and abuse have prompted criticism from groups such as the Electronic Frontier Foundation and legislative debate in the United States and Europe. Their adoption requires not only technological capability but also procedural measures that ensure that outcomes are defensible in court.
Najar Investigations, based in Murrieta, California, is one example of how private companies have attempted to navigate this changing terrain. Established in 2017 by Mohammed Najar, a disabled United States military veteran, the company focuses on the application of sophisticated surveillance methods as a foundation of its operations. In contrast to an approach that views technology as a substitute for street work, the business offers it as an enhancement of disciplined research procedures. The firm’s employees, who are often drawn from military or law enforcement backgrounds, are blending classic skills with technology, including data analytics tools, facial recognition software, and high-definition cameras.Â
A key differentiator of Najar Investigations’ methodology has been its focus on corroboration. While some agencies risk relying too heavily on algorithmic outputs, the firm incorporates technological outputs as part of a broader evidentiary framework. For instance, facial recognition matches are not treated as definitive evidence. Investigators cross-check them against secondary indicators like vehicle identifiers, records of past incidents, or unique physical attributes. The approach is consistent with a trend in private investigations that emphasizes accuracy and legal defensibility, such that any conclusion submitted to the court or the police is corroborated by multiple data points.
The legal environment has also defined how private investigators conduct their business. The state of California, where Najar Investigations is located, has strict regulations governing investigator licensing and ongoing controversy over the use of surveillance technology in civil and criminal proceedings. According to the California Department of Consumer Affairs, there were more than 10,000 licensed investigators working in the state as of 2023, making it one of the most active markets in the nation. In such a competitive market, the use of sophisticated technology has not only become a matter of efficiency but also a means of remaining relevant in an industry in which clients demand results that can withstand scrutiny.
One real-world example of how surveillance technology has been used by private investigators is in fraud cases. The Federal Trade Commission reported that in 2022, U.S. consumers lost nearly $8.8 billion to fraud, a significant increase from previous years. Investigators in this specialty frequently must track digital and physical activity across jurisdictions. Najar Investigations, consistent with this trend, has incorporated digital forensics along with field-based surveillance. By using cyber-tracking tools alongside traditional observation, the agency has been able to trace fraud networks and provide customers with actionable intelligence. The focus remains on generating evidence that can be used in collaboration with law enforcement, not on speculative results.
Training also plays a key role in how investigative firms adopt new tools in their work. Najar Investigations has a training framework for its investigators that involves legal compliance, ethical use of technology, and training on the latest surveillance tools. This is part of a broader industry trend in which professional associations, such as the National Association of Legal Investigators, require continuing education to maintain standards. The use of new technology requires not just access to devices but also skills in reading data responsibly and in providing results that comply with the law.
Drones have created another element of contemporary surveillance. The Federal Aviation Administration reported that more than 860,000 drones were registered in the United States by 2023 and that the number of drones used for commercial and investigative purposes was increasing. Najar Investigations is among the companies that have integrated drone technology into fieldwork, particularly when aerial viewpoints provide coverage of extensive areas. As with other technologies, the agency uses drones in accordance with federal and state law, employing them as an additive rather than a foundational source of evidence.
Beyond individual cases, the broader impact of these technologies is the transformation of private investigations toward hybrid models that integrate fieldcraft and data science. While others caution about the dangers of excessive reliance on technology, firms such as Najar Investigations demonstrate how balanced strategies can meet client requirements without compromising professional standards. Balance is especially crucial in civil litigation and corporate investigations, where the burden of proof requires investigators to present findings that are both thorough and defensible.
While debates over accountability, surveillance, and privacy persist in the United States and around the world, the use of cutting-edge technology by private investigators will likely continue to be questioned. Industry officials must demonstrate that such tools can be applied responsibly, with security measures that protect individuals’ rights without compromising clients’ needs. Najar Investigations, established in 2017, is one example of how private companies in Southern California and other regions have reoriented to meet this challenge by integrating traditional investigative methodologies with innovation.
