The ZBV® is the most maneuverable, versatile, and successful cargo and vehicle screening system on the market. Featuring Z Backscatter technology, the ZBV system can quickly reach places other systems can’t go, and scan objects other systems can’t inspect.  Its easy-to-read image quickly and clearly reveals threats like explosives, drugs, currency, and trade-fraud items such as alcohol and cigarettes—even in high-throughput environments like border crossings and security checkpoints.


  • Proven, reliable system in the toughest environments (hot, cold, sand, war zone) with greater than 95% operational availability.
  • Fully mobile, small footprint, self-contained, and operational within minutes of arrival on site.
  • Provides complete field of view of vehicles of all heights, including the tires
  • Scan Speeds: up to 10 km/h (6 mph)


The ZBV system developed by AS&E uses innovative Z Backscatter technology, which ensures a low radiation dose that is safe for operators, cargo, and the environment.

All companies that produce non-medical X-ray screening systems need to comply with the appropriate American National Standard Institute (ANSI) safety standards. The ZBV system fully complies with the applicable standards, including rigid adherence to the radiation dose limits prescribed in these standards.

Dose to Cargo: Less than 0.1 microSievert (μSv) per scan (equivalent to 10 microRem (μrem)), at an average speed of 5 km/h (3 mph) at a scan distance of 1.5 m (5 ft). Should a stowaway accidentally be scanned, the effective dose is well below the ANSI specified limit for accidental exposure and is equivalent to flying two minutes at altitude.


The ZBV system’s primary purpose is to screen vehicles and containers for contraband and security threats. If a person, such as an illegal stowaway, is present in the vehicle or container being scanned, the system creates only a silhouette with no facial or body detail. The system cannot be used to identify an individual, or their race or age.

AS&E’s customers use the ZBV system within their security and enforcement protocols and under the same national and local laws that govern their overall missions.

ZBV System Models

The ZBV system is available in three models to meet your real-world requirements:

  • ZBV C-Class: The original ZBV system built with a custom coach on a Mercedes-Benz® Sprinter cab chassis.
  • ZBV R-Class: Built for rugged terrain, the Ford® F550 chassis offers 4WD, additional ground clearance, and a crew cab for extra space.
  • ZBV S-Class: Built on a standard Mercedes-Benz Sprinter panel van for a contemporary appearance. Its reduced operational footprint is ideal for scanning objects in the tightest confines.

Tx-View Option for ZBV System

The Tx-View option for ZBV allows ZBV operators to simultaneously acquire dual-energy transmission images and photo-like Z Backscatter images of scanned vehicles for enhanced detection of threats and contraband. The images are acquired while the ZBV is operated in Stationary Scan Mode and vehicles drive between the ZBV and the Tx-View trailer. The Tx-View option is compatible with all ZBV models and built for the same rugged operating conditions as the ZBV system. It is completely self-contained for storage and transport, and can deployed quickly and easily.
