What is the DVR camera?

DVR camera is a security system that connects one or more cameras with a digital video recorder. The main advantage is that it can record a much longer period without having to change the tapes. This technology also means that you can immediately check the shots and continue recording. The input video is recorded on a hard drive rather than a video tape. Instead of connecting a cable or satellite box to the DVR, the user simply connects one or more cameras and records the source.

Using the DVR camera, it overcomes one of the greatest restrictions on the cassette -based recording. Usually even the biggest video tape recording at the slowest speed will be limited to eight hours of recording. This means it is impossible to use the system for a longer period of time without being at hand to change the tapes.

It is much easier to start the Multi Camera Camera system with DVR. For video tapes you need either a separate recorder for each screen, or you need to use a split screen system, which means thatThe picture recorded from each camera is smaller and therefore less detailed. DVR can process channels on the entire screen from multiple cameras simultaneously.

As the DVR records digitally, it is much easier to archive recordings in case you have to return to them later, for example in providing evidence in the crime investigation. Size and relatively low video tape capacity means that weekly recordings can easily fill the entire shelf. Many users are therefore forced to reuse tapes and only maintain a limited amount of shots. Shots from the DVR camera can be stored on DVD, which means that an easy -to -transmit case of 240 disks can contain archives from two years of recordings. The discs are much more portable than the cassettes, which means that CBI moves out of place for further security.

Another main advantage of DVR Camera is that you can play and record at the same time. At the cassetteYou couldn't follow the system recent shots such as checking the burglary attempt without waiting for the tape to be full or switching the belts. The DVR camera allows you to rewrite and monitor the shots from any point from a second to a hard drive recording.

There are also certain security benefits in the way the DVV camera is powered by a computer. You can set the password protection so that anyone who has stolen the hard drive would not be able to display shots. Some models can even be connected to the Internet and set up so that if the alarm is launched, the shots recorded just before the alert is automatically sent by e-mail to another computer, such as a home computer or even to the police.
