Surveillance cameras


Surveillance cameras are video cameras used for the purpose of observing an area. They are often connected to a recording device, IP network, and/or watched by a security guard/law enforcement officer. Cameras and recording equipment used to be relatively expensive and required human personnel to monitor camera footage. Now with cheaper production techniques, it is simple and inexpensive enough to be used in home security systems, and for everyday surveillance. Analysis of footage is made easier by automated software that organizes digital video footage into a searchable database, and by automated video analysis software. The amount of footage is also drastically reduced by motion sensors which only record when motion is detected.
