Achieve superior explosives detection and throughput with the industry's most compact multi-view checkpoint X-ray system

With the ACX 6.4-MV Automated Multi-view Checkpoint X-ray System, the company that invented multi-view technology for hold baggage screening delivers a compact, high-performance, multi-view checkpoint system ready for today's security challenges and tomorrow's regulatory requirements.

Combining the industry's most sophisticated automatic threat detection algorithms with powerful multi-view screening technology, the ACX 6.4-MV captures data from up to three views of a bag or object and provides the operator up to three high-quality images, displaying two at a

time, and automated alerts that enable airports and other high-security facilities to accurately detect threats, reduce false alarms and speed checkpoint throughput.

Highly compact, the ACX 6.4-MV integrates easily into existing operations. The system can be quickly upgraded from one view to two views to three views in the field, enabling enhanced automated threat detection. With its small footprint, superior flexibility and state-of-the-art threat detection, the ACX 6.4-MV enables users to meet evolving regulatory standards, operate with maximum efficiency and protect checkpoint investments.


  • Automated explosives detection
  • Weapons detection
  • Contraband detection
  • Asset protection

The L-3 Advantage.

Recognized for introducing multi-view technology to hold baggage screening and bringing automated explosives detection to the checkpoint, L-3 has continually set industry benchmarks for successful automated threat detection.

Exceptional Detection:

Improved Accuracy with Multiple Views

Designed to meet and exceed regulatory standards, the ACX 6.4-MV employs sophisticated patented algorithms proven to detect explosives rapidly and accurately. Fine-tuned over 18 years of field experience and collaboration with regulatory agencies, these algorithms come together with powerful scanning technology to deliver the most effective automated explosives detection available today.

The ACX 6.4-MV uses dual energy X-ray technology to measure the effective atomic number, mass, density and other physical characteristics of concealed objects. Software rapidly analyzes this information and immediately warns operators by placing a red box around suspicious items within the detailed image on the monitor. These alerts overlay high-quality top and side view displays that maximize clarity and minimize operator fatigue. Fast zoom (up to 64x) and an array of advanced imaging features such as Transparent Color™ allow operators to see an unprecedented level of detail, even in highly cluttered images. As a result, they can recognize suspicious objects-such as IEDs, knives, guns and contraband-much more efficiently and take appropriate action.

With its modular design, the ACX 6.4-MV can easily be expanded from one or two views up to three views. The three-view system interprets data from all three views to deliver enhanced explosives detection- including automated detection of liquids-enabling

users to address emerging threats or regulations. When combined with L-3's commitment to advancing the state of the art in automated detection and ongoing algorithm enhancements, the ACX 6.4-MV's flexible architecture brings you a leading-edge system that grows with your needs.

Outstanding Throughput:

Faster Screening through Fewer False Alarms

With the ACX 6.4-MV, threat detection is better-and faster. The combination of highly efficient software and a fast scan rate of more than 700 scans per hour produces superior throughput without sacrificing accuracy. High-resolution images and automatic highlights of potential explosives help operators make better decisions quickly, reducing the number of repeat scans and hand inspections. A full suite of exclusive user-friendly programmable image enhancement tools further allows screeners to readily examine questionable objects.

More effective detection of explosives and other threats means fewer false alarms and streamlined operations. Checkpoint personnel can clear bags faster, which improves flow, shortens lines and results in greater convenience. As the regulatory environment evolves, the advanced capabilities of the ACX 6.4-MV will enable you to adopt more streamlined checkpoint processes, such as screening a laptop for explosives while it remains in a bag.

Presented side by side, high-quality top and side views of a screened bag enable operators to discern threats confidently. The system automatically places a red box around possible explosives to alert operators immediately.

The ACX 6.4-MV's dual-monitor operator stand offers flexibility: The ergonomic stand can be easily rolled to different locations, while adjustable monitors accommodate operators of different heights and offer the option of sitting or standing.

Investment Protection:

Small, Flexible & Compatible

The ACX 6.4-MV is designed with the bottom line in mind, and can grow with your needs while delivering the lowest cost of ownership of any comparable system. Bringing together leading-edge automated explosives detection and highly configurable technology, the ACX 6.4-MV provides an ideal long-term platform for a more effective checkpoint.

  • Upgradeable in the field-in just hours. The one-view or two-view ACX 6.4-MV can be upgraded to a three-view system for enhanced automated threat detection. With the system's modular design, upgrading hardware and software takes just hours, not days-minimizing downtime and disruption.
  • Small footprint. With the smallest footprint of any automated, multi-view X-ray checkpoint system, the ACX 6.4-MV integrates easily into existing checkpoints without costly reconfiguration and saves space for new security checkpoints.
  • Compatible with existing equipment. In most cases, you can reduce your costs by using the ACX 6.4-MV with existing conveyors, roller tables and bin return systems.
  • Easy to learn and use. User-friendly displays and a touch-panel interface make the system intuitive for operators, accelerating new deployments and reducing ongoing training costs.
  • Rich networking capabilities. Designed to U.S. Transportation Security Administration (TSA)-compliant Security Technology Integrated Program (STIP) standards, the ACX 6.4-MV supports your ongoing networking needs. Features include TCP/IP communication protocols, decentralized and remote monitoring, reporting and system management, as well as Threat Image Projection (TIP) configuration, control, database management and reporting.
