A lot of the terminology when talking about security and surveillance cameras can be hard to track, not least because people use the terms informally and interchangeably all the time. Basically, surveillance cameras are usually used with CCTV, in businesses and where there is continuous recording. They are meant to record acts as they happen, so they can be investigated later. Home security cameras, by contrast, are often motion-triggered and connected to cloud storage. Often, people install them primarily to deter would-be burglars.
