CCTV Camera Vandalism
Unless physically protected, CCTV cameras have been found to be vulnerable against a variety of (mostly illegal) tactics:
- Some people will deliberately destroy cameras. Some cameras can come with Dust-Tight, Pressurized, Explosion proof, and bullet-resistant housings.
- Spraying substances over the lens can make the image too blurry to be read.
- Lasers can blind or damage them. However, since most lasers are monochromatic, color filters can reduce the effect of laser pointers. However, filters will also impair image quality and overall light sensitivity of cameras (see laser safety article for details on issues with filters). Also, complete protection from infrared, red, green, blue and UV lasers would require use of completely black filters, rendering the camera useless.

Famous quotes containing the words camera and/or vandalism:
“The camera is a killing chamber, which speeds up the time it claims to be conserving. Like coffins exhumed and prised open, the photographs put on show what we were and what we will be again.”
—Peter Conrad (b. 1948)
“But look what we have built ... low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace.... Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums.... Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.”
—Jane Jacobs (b. 1916)
