CCTV technicians spend the majority of their time installing and maintaining CCTV systems. Additional duties include monitoring equipment, preparing purchasing requests for materials needed for each project and writing daily and monthly reports regarding maintenance work provided. They must often communicate with customers to explain problems and procedures with the equipment.

CCTV engineers are sometimes required to have a formal education or in the field of electronic services, such as a two year technical certificate. Educational requirements for CCTV technicians may vary based upon the specific needs of individual security firms.
