Digital Video Recorder
The DVR technology is used for two purposes- either to record channels or for surveillance.
Surveillance
The system can be used to monitor such homes and businesses which are in need for advanced security measures. Once this device is connected to a Personal Computer, it will help you to watch a particular area 24 hours of the day. If your business is diversified and you have offices in a number of countries all over the world, the DVR device makes it possible for you to keep an eye on activities in your London and Atlanta organization. This is possible because the DVR can be connected to the World Wide Web which will allow you to view images as and when they are formed.
The machine has impressive storage capacity and will allow the user to store recorded footage for over two months. One can do away with old-fashioned videotapes and avoid loss of important data by depending on this technology.
The surveillance system consists of a number of components, namely, motion sensors, zoom controlling, multiplexer, CCTV connections and color quad processors. The zoom control is extremely beneficial as it will make it possible for you to view every corner of the targeted room. This way, you can make do with a single camera. The motion sensor helps to capture moving images. Therefore, you will not have to sit through hours of recorded footage as the DVR will only begin recording when motion is noticed. This also helps to save space on the memory card. The footage can then be transferred onto a CD or Pen Drive if it needs to be sent over to a third party.
The moving image can then be separated which makes it easier for the concerned party to recognize faces. Some machines also make it possible to record audio. Safety is ensured if you buy a DVR which is why most malls and banks are demanding the machine more and more.
Record Channels
If you are fond of sitcoms and can’t catch them at the right time, no matter how hard you try- a DVR or a Digital Video Recorder is the answer to all your prayers. Several companies manufacture this equipment which makes it difficult for the customer to make a choice. Apart from doing adequate research about the company’s credibility, you must also keep a number of features in mind. This will ensure that you buy the right DVR.
Different types of recorders are available in the market today such as –
Stand Alone Recorder, Set-Top Box, Computer Digital Video Recorders and Portable Digital Video Recorders.
Hikvision
