A guardhouse is a small building or structure typically located at the entrance of a military base, prison, or secure facility. Its primary purpose is to provide a space for security personnel to monitor access, check identification, and ensure the safety of the area. Guardhouses often contain equipment such as surveillance cameras and communication devices. In addition to serving as a checkpoint, guardhouses may also house administrative offices for security staff. They are designed to be easily defensible and may include features like reinforced walls and secure entry points. Guardhouses play a crucial role in maintaining security and order in facilities like military bases and correctional institutions.
