CCTV Video Recorders

CCTV video recorders are electronic devices that process video signals received from CCTV cameras and record the content to storage media such as a hard drive or to a cloud-based storage service.


 


How do CCTV video recorders work?


CCTV video recorders capture raw data in various file formats using secondary devices such as CCTV cameras. The captured signals are then quantified and compressed. Advanced digital video recorders (DVRs) allow users to access security footage remotely from computers or other internet-enabled devices. Most CCTV video recorders can record and play various video file formats and resolutions as well as images.


 


Types of CCTV video recorder


CCTV digital video recorders can be classified into four main categories:



  • Computer-based DVRs

  • Set-top-box-based DVRs

  • Portable DVRs

  • OTA (over the air) standalone DVRs


 


Applications of CCTV video recorders


CCTV video recorders are commonly used with physical security applications to record CCTV camera footage in a range of commercial and residential applications such as in or around the home, shops, restaurants, public libraries and an increasing number of public areas.
