| Surveillance devices allow law enforcement and corrections officers to watch (and thus safeguard) particular locations remotely. Such devices permit officers to observe or find individuals who otherwise might not be visible because of obstructions or darkness. Current technologies include closed-circuit television security systems, a variety of night vision devices using infrared and available light sources, and through-the-wall surveillance devices. The latter have great potential in effectively resolving critical incidents (section II), such as hostage taking. |
