Law enforcement can turn to manufacturers or system integrators
First, agencies can purchase simple and effective systems from manufacturers such as Axon and Getac. Usually, an agency purchases hardware such as body-worn or dash cams and receives a back-end system at no additional cost. These back-end systems manage the digital evidence collected by the hardwareand they allow agencies to apply many features and filters to that evidence.
In many cases, these digital evidence management solutions can ingest content from other media systems and catalog these files in a wide range of formats, including videos, photos, documents, and more. Often this non-native import process does not capture metadata, so some agencies have designed scripts that help automate this process.

Second, national and local investigators can turn to systems integrators, such as Genetec and Hitachi, which do not produce hardware like body cameras. These companies support a vendor-neutral and content-agnostic enterprise digital evidence management system capable of sifting through multiple sources of entry. These solutions are likely to appeal to criminal investigation offices, while single-vendor solutions may appeal more to law enforcement agencies.
Systems such as Genetec Clearance can record private cameras that participate in agency partnerships. Private companies can allow first responder agencies to access their live video in an emergency or give investigators access to post-incident video to search by date and time or other factors.
State-of-the-art tools help investigators with data management
In addition to searching for digital evidence, criminal justice agencies have an interest in sharing and moving files. State-of-the-art tools make this easier than before. A district attorney must receive evidence to act on it. Digital evidence management solutions make it easier for this AD to manage and process that evidence to sort it and send it where it needs to go.
A typical DA in the United States oversees criminal justice proceedings in a wide range of cities and possibly even counties and a state. A DA can obtain Axon cloud data from an agency combined with Panasonic i-PRO data from another, as well as analog tapes from some legacy systems. Private company video and stills provided by civilian bystanders may also be available. DA offices should standardize the receipt and processing of this evidence.

When it comes to understanding the available data, investigators can now turn to artificial intelligence for help. Veritone produces a leading digital forensic tool based on AI. The provider uses AI to analyze media collected by criminal justice agencies. It can search through a video repository to identify specific people or things. For example, it can distinguish people of interest by height and hair color and track their media presence during a specific date range.
The AI can also search for audio or text without having to manually clean files. As such, AI can speed up searches that once took hours or days, reducing them to seconds in some cases.
