What
is DVR? |
|
|
Previous method for recording CC-TV on tape with tape-recording equipment is an analog type. Therefore, it is very inconvenient to change the tapes frequently and it lowers the quality of image. However, a Digital Video Recorder or DVR, digitally records the video image so it provides clear image like a picture. It also has a function to record continuously so you don't have to worry about the frequent change of tapes. DVR, therefore, is a video recording surveillance system for the next generation and it is growing very rapidly. In addition to that, it has communication function which enables you to detect remoteness screen even from household and it contains a multi branch of up-to-date function.
