Online businesses that sell high-end security systems offer bundles or packages that include all required hardware and technology, making it easier for buyers to locate what they need. The CCTV DVR recorder is included, but it can also be purchased separately and set up with the remaining components according to the instructions. This same type of equipment is available from cable companies for recording and storing TV shows when users cannot watch them live. The premise is the same, except that photographs of your house or office are captured on camera and saved for offline viewing instead of data.
