Which of the following is NOT one of the seven types of searches conducted on an inmate?

In the context of the types of searches conducted on inmates, the term "surveillance search" is not considered one of the established seven types. The other options listed are indeed recognized search types utilized in correctional facilities for various reasons, including security and safety.

Custodial searches are conducted after an inmate is taken into custody to ensure that no contraband or weapons are present. Full body searches involve thorough examinations of an inmate's entire body, often used in high-security situations. Visual searches, on the other hand, are observational checks where staff may look for any signs of contraband or suspicious behavior without direct physical contact.

Understanding the types of searches performed on inmates is crucial for maintaining order and security within correctional facilities. The distinction between these types of searches and the idea of surveillance, which generally refers to monitoring behavior rather than physically searching individuals, helps clarify the correct answer.
