Everyone is familiar with camera surveillance at banks, high-end stores, and office buildings. In a post-Newtown world, however, surveillance cameras are becoming increasingly familiar in neighborhood schools. In fact, after the tragedy in December, over 62 of the 400 bills relating to school safety nationwide, pertained to surveillance cameras.
Proponents argue that cameras in schools can be an efficient, minimally intrusive method of security. Unlike metal detectors or guards, cameras do not significantly impact the daily lives of students and teachers. Cameras are also more affordable than other forms of security. “They (schools) can now buy 10 cameras where they could afford two before, so they’re becoming more mainstream,” said Bob Stockwell, a global technology leader with Stanley Security.
Cameras are not only easily accessible, they are also able to provide sharper images and greater storage capacity, enabling footage that is easy to view, store, and share. This technology is considered a cutting edge way of keeping schools safer.
