O que é gravador DVR, NVR e HVR?

DVR-SECURITY-BUSINESS

O gravador é o equipamento utilizado no sistema de CFTV para gerenciar e armazenar os dados de áudio e vídeo enviados pelas câmeras.

De acordo com o sistema implementado ele pode ser um DVR (Digital Video Recorder), para os casos das imagens enviadas por câmeras analógicas, um NVR (Network Video Recorder), quando as imagens são enviadas através das câmeras com tecnologia IP, ou ainda, um HVR (Hybrid Video Recorders), quando são utilizados os dois tipos de câmeras simultaneamente.
