Del. Code tit. 14 § 4121
The school board of each school district shall have authority to establish and implement programs to use video cameras for surveillance on public school property, including, but not limited to, classrooms, halls, auditoriums, cafeterias, gymnasiums and parking areas, for the purpose of monitoring student behavior to help ensure the safety of students and teachers. However, no video camera shall be used for classroom surveillance, pursuant to this section, unless the principal of the school and the teacher of the classroom consent to the surveillance.
Before exercising its authority under this section, a school board shall promulgate rules and regulations governing the implementation and use of video cameras in classrooms. However, in no event shall video cameras be used at any time or at any location which would violate a student's reasonable expectation of privacy including, but not limited to, locker rooms, areas where students may disrobe and lavatories.
