Government and Critical Infrastructure
Government offices, correctional facilities, courts, utilities and defence sites screen fewer people than an airport but carry a much higher consequence for a miss, and a much stronger requirement to prove what was checked.
What goes wrong
- Devices that are switched off are invisible to RF sweeps
- Suspect items cannot be moved to a fixed scanner
- Phones enter restricted areas despite a stated policy
- Vehicle undercarriages are checked by eye with no record kept
- Alarm logs without identity cannot answer who was screened
What the equipment has to do
- Non-linear junction detection that responds to the semiconductor, not a transmission
- Portable X-ray that goes to the object rather than the reverse
- Trace detection for explosives and narcotics at the checkpoint
- Under vehicle imaging with a retrievable, comparable record
- Gates that tie identity, entry-exit records and screening together

Typical scenarios
- Sweeping a meeting room before a sensitive discussion
- Assessing a suspect package where it lies, with a remote specialist advising
- Vehicle entry screening with plate recognition and stored undercarriage images
- Phone detection at the entrance to a confidential facility
How we work through it
- Define the threat you are actually protecting against, not the equipment category
- We propose the detection principle first, then the model
- Export and import controls confirmed for the destination before you commit
- Commissioning, operator training and documentation scope agreed
- Service and spare-parts terms set out with the order
What we deliver beyond the equipment
- Equipment carrying stated certifications where the source documents exist
- Field service technicians trained on emergency repairs and routine maintenance
- Rental and leasing for temporary or project-based deployments
- Training and testing aids supplied with the equipment

Under Vehicle Inspection Mirrors Cameras and Scanners Compared
Three different tools for the same job, separated by what they record and how many vehicles you have to process.
Trace Detection for Explosives and Narcotics How It Works
Trace detection finds residue left by handling, which is how a checkpoint catches someone carrying nothing at that moment.
Finding Electronic Devices That Are Switched Off
An RF sweep finds transmitters. A non-linear junction detector finds the semiconductor, which is why it works on a device that is powered down.
Government and Critical Infrastructure FAQ
How do we find a recording device that is switched off
A non-linear junction detector such as the VT-801 or VT-802 responds to the semiconductor itself, which is why it works on dormant devices.
How do we assess a package we should not approach
The VT-808 supports remote distortion-free listening from a drone or robot, and the handheld backscatter imagers work single-sided at the object.
Do you supply equipment with certification documents
Where the source documentation exists, yes. Several products cite Ministry of Public Security certification, GA1236-2015 or EU CE. We will send what the factory can actually provide for your market.
Can these be exported to our country
Detection and counter-surveillance equipment is controlled in many markets. Tell us the destination and end use before you order.
Can screening be tied to identity records
Yes, the VW-2286S provides 1:1 and 1:N facial verification with complete entry-exit records.
