The Interview Room Management System from Linear Systems was created to help detectives work more effectively during investigations. As a complete interview video recording management platform, it preserves and manages evidence captured during interviews while reducing manual effort. By digitally equipping interview rooms and automating the recording process, investigators can stay focused on solving cases rather than managing technical systems.
DIMS system combines high-quality digital audio and video recording with structured case management features. Every recording is automatically time-stamped and linked to its case file, maintaining traceability across the evidence lifecycle. Metadata such as date, location, interviewer ID, and device information is attached to each file, creating a transparent and defensible record.
Streamlined Interview Room Solution
DIMS Interview Room Solutionis designed to handle every phase of interview recording from capture to archiving. Its intuitive interface minimizes user training and allows detectives to operate the system confidently. The process is entirely digital, eliminating issues common in traditional recording setups such as missing files, manual transfers, or lost notes.
Multiple audio and video sources can be recorded simultaneously, including a separate audio track for transcription. Investigators can also mark key moments using “flags,” add written notes during or after interviews, and access them later through search functions. These features make post-interview analysis faster and more organized, helping agencies maintain accurate, searchable records.
Metadata and Timestamps for Reliable Case Management
The addition of metadata and timestamps is crucial for digital evidence management. Every interview captured in DIMS carries embedded data that verifies when, where, and by whom the recording was created. This automated tagging provides verifiable authenticity, supports chain-of-custody records, and simplifies discovery during court proceedings.
Additionally, DIMS provides the option to generate copies of recordings with notes and flags for sharing with prosecutors or other authorized parties. These copies can be encrypted or watermarked to maintain confidentiality and data integrity.
Seamless Integration and Secure Storage
Through direct integration with the DIMS ImageServer, all interview recordings are automatically transferred to centralized, redundant storage. This system provides continuous availability and controlled access to authorized personnel. Video, audio, and associated metadata remain synchronized throughout their lifecycle, preventing data loss or unauthorized alterations.
The DIMS Mobile App has been engineered to capture and ingest nearly every evidence file type without interrupting existing workflows. Photos, audio, video, and documents can be captured or uploaded directly from a secure application environment. Unlike standard device cameras, evidence files are never placed in the personal gallery; instead, they are stored within encrypted app storage.
Once acquisition is completed, the app automatically initiates a secure upload to the DIMS ImageServer over a high-speed mobile connection. Each file is verified by checksum to confirm integrity and maintain compliance with chain of custody protocols before removal from local storage.
Metadata, including geolocation, timestamp, device ID, and authorized user credentials, is attached to each asset at the moment of capture, creating a defensible record. Administrators can configure policies, permissions, and encryption settings remotely, while automatic receipts log every transaction. This process allows agencies to ingest all file types seamlessly while maintaining security and evidentiary reliability.
Secure Evidence Collection from the Field
Evidence can now be acquired directly at the scene with the DIMS Mobile App. Still images, video, and audio recordings can be captured on a smart device without docking to a computer. Every file is sent directly to the DIMS ImageServer, eliminating delays and preserving the integrity of the chain of custody.
Customizable App Controls and Policies
Each agency can configure workflows, permissions, and security settings through the administrator panel. “Write Once, Run Anywhere” technology allows updates and policy changes to be pushed automatically to all connected devices. Detectives and officers are therefore guided by agency policies in the field, with compliance enforced at every step.
Asset Handling and Chain of Custody Protection
Captured files are never stored in a device’s native gallery. Instead, assets remain in app storage until they are successfully transferred to the DIMS ImageServer. Once confirmed, they are automatically removed from local storage. This design prevents tampering, protects authenticated interview recording, and upholds the chain of custody. Deleted assets, when authorized, are redirected to dated folders on the ImageServer for later review.
Metadata Preservation for Every Capture
All files acquired through the DIMS Mobile App include metadata such as GPS location, date and time (based on the carrier network), device type, and authorized user details. This embedded information strengthens credibility in court.
Advanced Features for Investigators
The Mobile App has been equipped with tools that help investigators in the field:
Blackout Mode allows covert recording while the device appears powered off.
Photo Preview supports zooming for detailed review.
Audio Controls provides rewind, fast-forward, and slow-play options.
Video Playback uses the device’s native capabilities, controlled by administrator permissions.
Each transaction generates a receipt, giving transparency to the process. Screen capture logging also alerts administrators whenever screenshots are taken, helping protect sensitive information.
Transparent Acquisition with Full Authentication
Every user must be authenticated by the DIMS Mobile App and verified by the ImageServer. Asset receipts record each action, providing transparency from acquisition to storage. These logs support audit trails that are critical for digital evidence management and defensible courtroom presentation.
By combining mobile capture with Acquire Stations, DIMS enables agencies to ingest virtually any file type. Whether captured in the field or uploaded in the office, evidence is managed securely through one platform. The result is a system that reduces bottlenecks, accelerates investigations, and preserves the reliability of every file.
Law enforcement agencies handle massive amounts of digital evidence every day. From body-worn camera video to 911 audio, interview recordings, documents, and forensic images, every piece of evidence must be stored, authenticated, and retrieved quickly when needed. DIMS Interview Management System and digital evidence management platform have been designed to meet these demands by offering full-asset search and rapid retrieval capabilities. With DIMS, investigators are given the ability to search everything and find anything, without delays or risk to evidentiary integrity.
Managing High Volumes of Digital Evidence
Agencies are often challenged by the sheer scale of evidence. Files can originate from hundreds of sources, including patrol units, specialized task forces, and interview rooms. With DIMS, millions of assets are ingested and securely stored while remaining instantly searchable. The system supports industry-standard and proprietary formats, protecting the original file while maintaining access to working copies for investigators, prosecutors, and authorized staff.
Rapid Retrieval for Investigative Efficiency
Time is critical during an investigation. Delays in locating or authenticating evidence can affect case outcomes. DIMS allows detectives and administrators to perform rapid searches across video, audio, notes, metadata, and even flagged segments within interviews. Whether searching for a specific keyword in written notes, a flagged portion of an interview, or a file type from a specific device, evidence is retrieved in seconds. This ability confirms that law enforcement interview recordings and other digital files are available exactly when needed.
Full-Asset Search Across Formats and Devices
Evidence does not come in a single format. The digital interview room system, body-worn cameras, in-car video, 360-degree laser scans, and forensic documents all create unique data types. The DIMS platform has been designed to handle this diversity by providing a unified search function. Investigators can filter by date, location, file type, case number, or keyword, making retrieval consistent and defensible.
Authentication and Chain of Custody
Rapid retrieval does not mean reduced security. Every action in DIMS is logged, and every asset is hashed, creating an unbroken chain of custody. Search results, user access, and system configurations are documented automatically. This approach provides agencies with authenticated interview recordings and evidence files that can withstand courtroom scrutiny. Logs and audit trails confirm that evidence has not been altered, supporting defensibility and agency credibility.
Scalable and Secure Evidence Management
The DIMS Interview Management System and digital evidence sharing platformprovide scalability for agencies of all sizes. Whether supporting one interview room or thousands of evidence files across multiple sites, the system maintains rapid retrieval and search functionality. With full redundancy, cloud or hybrid storage options, and strict compliance with CJIS and legal standards, DIMS offers agencies a secure and affordable solution for managing evidence.
From crime scene to courtroom, investigators are supported with a solution that allows them to search everything and find anything (as permissions allow), reliably, securely, and at the speed required by modern law enforcement.
Law enforcement interviews must be recorded with accuracy, reliability, and security. A digital interview room system provides agencies with the ability to capture and preserve interviews in a defensible manner. Linear Systems Interview Room Management System was developed to provide detectives with advanced tools that maintain evidentiary integrity while remaining user-friendly. By supporting multi-camera and multi-room configurations, interviews can be recorded in a way that meets the highest standards for digital evidence management.
Multi-Camera Flexibility for Clear Recordings
Interviews are often complex, requiring more than a single camera angle. With DIMS, one to three cameras can be installed in each room, capturing both wide and close perspectives. High-definition cameras, whether fixed or PTZ, can be used in overt or covert configurations. The result is an authenticated interview recording system that provides a complete view of the suspect and the interaction. Separate audio channels can also be recorded, ensuring accurate transcription and supporting case preparation.
Managing Multiple Interview Rooms with Ease
DIMS Interview Management System is designed to manage up to four rooms per Capture Station. Detectives can monitor multiple rooms simultaneously, with live viewing available through the Remote Viewer module. Each recording is automatically stored in redundant databases, eliminating the risk of lost evidence. With law enforcement interview recording software handled in this automated way, detectives can focus on the task of conducting interviews rather than managing technology.
Features That Support Investigators
Investigators are supported by a range of tools built into the digital interview room solution. Notes can be added to the recording during or after the session. Flags can be discreetly inserted, enabling quick reference without disrupting the interview. Prompts can also be sent by colleagues through email or text messages, improving questioning strategies without alerting the suspect. These features provide flexibility while maintaining a secure record.
A defensible interview requires more than a recording; it requires integrity. The Interview Management System automatically manages authentication and the chain of custody. Files are simultaneously recorded to the system’s hard drive and to DVD, creating redundancy. Export to the DIMS ImageServer further secures the recordings with centralized, redundant storage. Logs and audit trails are maintained, providing complete transparency and defending against challenges in court.

In law enforcement, recorded interviews play a critical role in investigations and court proceedings. The Digital Interview Room Management System was developed by Linear Systems to provide a complete, defensible, and secure digital interview recording solution. With audio and video fully automated, detectives can focus on the interview itself rather than operating complex equipment.
Reliable Interview Recording for Law Enforcement
A Linear System secures that every interview is captured with crystal clear video and audio. Separate audio tracks can be recorded for transcription purposes, supporting accuracy in case files. High-definition digital or analog cameras, covert or overt, can be installed, with support for fixed or PTZ setups. Each interview room is equipped with two cameras and two microphones, and up to four rooms can be managed per Linear Systems’ Interview Room Capture Station.
Protection Against Claims and Misconduct
Misconduct claims, coercion concerns, or abuse allegations can be defended against when accurate recordings are presented. Interview videos allow jury members to view the suspect’s responses directly, reducing doubts about authenticity. Investigators are shielded by defensible, authenticated recordings, which are managed with a verifiable chain of custody.
Advanced Features for Investigators
The Interview Rooms are equipped with practical features that assist investigators during live interviews. Notes can be inserted into the recording either during or after the session. Flags can be discreetly placed without the suspect’s knowledge, enabling quick reference later. Chat prompts can be sent to the interviewer in real time, supporting better questioning strategies without interruptions.
Authentication and Chain of Custody Management
Maintaining the chain of custody is essential for interview evidence. Linear Systems automatically authenticates and manages interview files, whether video, audio, or flagged portions. Simultaneous recording is conducted to both of the system’s internal hard drives, providing redundancy and eliminating challenges to data integrity. Once recorded, interviews can be automatically pulled into the DIMS ImageServer, where redundant storage and centralized access are provided for authorized users.
Integration with Agency Policy and Procedures
The Digital Interview Room Management System, coupled with DIMS ImageServer, enforces agency policies and supports compliance with law enforcement standards. Chain of custody logs, user access controls, and audit trails are maintained automatically. Integration with DIMS eliminates the risk of unauthorized copies, provides secure and remote access to authorized users, strengthens agency credibility, and reduces liability in courtroom proceedings.

DIMS Mobile App (Android & iOS) is on the way. It’s designed to let authorized personnel capture photos, video, and audio at the scene and deliver them securely to your agency’s DIMS ImageServer no docking station or office stop required.
Why a Mobile Evidence App Matters
The minutes after an incident are when details fade and evidence can be lost. A purpose-built mobile app closes that gap by putting policy-driven, secure capture in every trained hand; officers, detectives, crime scene techs, and any unit that documents incidents in the field (campus security, corporate investigations, code enforcement, environmental response, insurance SIUs, and more).
Built To Fit Your Agency
Every agency operates differently. DIMS Mobile is being built so your DIMS Administrator can tailor it to your policies and procedures:
Custom workflows & permissions by role or unit
Configuration updates pushed to devices (“write once, run anywhere”)
Settings that enforce policy in the field without retraining or re-deploying the app
Chain of Custody, by design
Planned safeguards focus on evidentiary integrity from the moment of capture:
No camera roll: assets live in secure app storage, not the personal gallery
User authentication against your DIMS ImageServer
Verified delivery: local copies are removed after server confirmation
Standard file formats for review and disclosure**
Rich metadata (when available): geolocation, device time, device details, authorized user
Administrative controls: optional screenshot logging, restricted deletion (admin-authorized), and asset receipts for full transparency
Thoughtful Tools for Real Work
To help teams confirm they “got it” before leaving the scene, the app is planned to include:
Blackout Mode (where policy permits) for discreet recording
Be The First To Try IT
We’re preparing early access with select agencies. If you’d like to pilot the DIMS Mobile App or help shape final features and policy controls, join theearly access interest list, and we’ll follow up with next steps.
