Campbell Security, currently known as Campbell/Harris Security Equipment Company (CSECO), is the leading name when it comes to contraband detection tools. It is principally renowned as the creator of the Buster density meter and contraband detector, although the company has a stellar number of other contraband detection tools as well.

Campbell/Harris Security Equipment Company (CSECO) as we all know, is the creator of the Buster density meter and contraband detector. Developed and designed by company founder Patrick J. Campbell with significant input from the Customs and Border Protection (CBP) agents, the Buster does the job of detecting hidden contraband in a quick, accurate and efficient way, but is also surprisingly easy to use.

A contraband detector is one of the essential tools law enforcement depend on to help them detect and locate hidden contraband in a quick and non-destructive way.

The task of detecting and locating hidden items, such as narcotics and other types of contraband items, on security and national border checkpoints is certainly no cushy job. To top it all off, it can be also dangerous. Case in point: inspecting tanks that store flammable or combustible liquids such as fuel or gasoline or certain chemical substances.

Visual inspection tools, such as a videoscope security equipment, are a significant addition to every drug interdiction agent's or border patrol officer's arsenal. These are the essential tools because they allow the users to confirm, through their own eyes, whether anything is indeed hidden inside the objects they're inspecting.

There are different types of density meters according to their purpose and usage. In law enforcement, the best density meter is a device that measures the density of an object that is suspected of hiding contraband. That object can be almost anything – tires, furniture, bulkheads, cargo, spaces between walls, any types of vehicles and their empty spaces, and a lot more.
