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.

Campbell/Harris Security Equipment Company (CSECO) is known for the Buster density meter as a drug interdiction equipment. It was developed by the company founder Patrick J. Campbell with significant input from a team of U. S. Customs and Border Protection (CBP) officers to ensure that it would work as it was intended: to effectively detect narcotics and other types of contraband hidden in vehicles, walls, furniture, cargo, and other items.

Whether you are a police officer, detective, or a special agent, each of them belongs to law enforcement. Their main duty, among others, is to keep the entire community and nation safe from crime and any suspicious and illegal activity.
