Many digital video recorders can transmit video signals to intranet or internet while recording. So one can watch the situation of his/her premises with computer or mobile phone without interruption of recording. Authorized person can also control the system remotely. 很多數碼視像錄影機都可在錄影的同時經內聯網或互聯網傳送視像訊號，所以閉路電視系統的授權人士可透過電腦或手提電話監控該系統而不影響錄影。
