Surveillance sounds like an intimidating word, but essentially it is filming and recording locations you wish to secure. This could be the exterior of an office or home with the most common being the front door, or doorbell camera. Video cameras can be placed inside as well.

Interior cameras have become more commonly integrated into the security system. They can be placed overtly to monitor pets or small children while away. More clandestine cameras, usually referred to as “nanny cams,” can also be installed for discreet monitoring of sensitive areas.
