Spectrohm

Spectrohm is a United States startup that makes security screening and inspection systems for bags, packages and cargo.

The company says its aim is to make screening safer, faster and more accurate. It points out that about 400 billion bags and parcels move each year, and only a few percent can be checked today. Its answer is a patented method that uses radio waves to look inside an object and also tell what it is made of. This works while items travel on a fast conveyor, at up to 3 meters per second.

The radio waves carry less energy than a cell phone call. The systems have wheels and need no heavy shielding or special power. They do not need an X-ray operator for radiation safety. The data the system collects can help AI tell apart items that look alike, such as milk, gasoline and water.

Spectrohm has two products. CheckStream is a portable system for bags and backpacks. It checks personal items without opening them. It can run on a battery, indoors or outdoors, and the company says it can raise bags screened per operator by up to four times. It looks for firearms, knives and bladed weapons, and metallic and non-metallic explosive devices. Venues named include sports events, concerts, festivals, museums, theaters, schools, conference centers and theme parks.

CargoStream is a belt-fed system for packages. It is used for mail and package screening, cargo inspection and commercial or industrial inspection. The company says this kind of screening can help stop threats from entering buildings, find wrongly declared imports and spot hazards and fraud. Luggage screening is also listed as a use.

Spectrohm can adapt either product to commercial or government needs. It also offers analysis services, including radio frequency imaging, dielectric imaging and several kinds of tomography. It is looking for venues and security experts to join a pilot program. It has exhibited at ISC West 2026 in Las Vegas and GSX 2026 in Atlanta.
