CCTV Surveillance Cameras are fast becoming common place as advances in its technology has made it much more affordable. CCTV cameras are now installed in homes, shops, businesses and office, acting as a deterrent to crimes as well as helping home and business owners keep an eye on what is happening in their absence.
The use of CCTV Cameras in the home has extended beyond mere protection, to include remote supervision and monitoring of domestic helpers, young children as well as elderly relatives. CCTV Cameras installed in the shops, while serves as a good deterrent to shoplifting, has been used to help management supervise and manage customer service standards.
There are two main components of a CCTV System: the Digital Video Recorder (DVR) and the CCTV Cameras.
Digital Video Recorders are recorders that record video digitally on hard disks. Compared to the old medium of video cassette tapes, hard disks are far more superior in the ease of storage, backup and retrieval. And unlike tapes that can go moldy over time, affecting picture quality, hard disk does not have these limitation. It is hence little wonder that the Digital Video Recorders are fast replacing the older Time Lapsed Video Recorders.
There are two types of Digital Video Recorders: the Embedded DVR and the PC-Based DVR. Embedded DVR utilised an operating system that was booted from memory, not from a hard disk whereas pc-based DVR utilized either Windows or Linux as its operating system booted from hard disk.
