A Guide to The Digital Video Recorder
Digital Video Recorders: An Overview
In what now seems like ancient times, security cameras operated under a different principle. Closed circuit recording was transmitted to a television and recorded by a VCR. With VCR tapes as a nearly dead technology, this solution is no longer practical. Tapes take up valuable space, creating clutter in places, which could be otherwise utilized more effectively. VCRs are both bulky and obtrusive. They lack subtlety, and are often mistakenly turned off. It is easy to record over VCR recording, putting strong evidence at risk for deletion. Videotapes are not only clunky and outdated, they are also risky. When it comes to catching an intruder, an embezzler, or other threat to security.
Today, methods of recording are much more reliable. Sophisticated security systems have created a call for a better system for recording and reviewing important surveillance video and audio. The majority of recording is done by digital video recorders, or DVRs. A DVR is much more accurate for a number of reasons. It is also a more convenient form of recording, with a higher degree of efficiency. Digital files take up very little space as does the digital video recorder equipment itself. Transmissions can easily be organized by both date and camera view. Because the files recorded are digital, it is are easier to edit and view them with the aid of sophisticated software, allowing for greater visibility of any scene captured by surveillance system. Ultimately, this could mean the difference between catching a thief and looking at a blurry image in confusion. The new era of digital recording is making the world safer, home by home, business by business, and digital video recorder by digital video recorder.

There are a number of people who could benefit from a digital video recorder. An important element in any security system, it is important to consider all aspects of the digital video recorder in terms of its functionality as part of a home or business's interface.

Digital video recorders come with different types of software. They also have the option of being integrated with cash register POS systems. Amount of storage in a DVR varies greatly. Some allow for the addition of extra memory, externally. Others have a high capacity hard drive. Systems may be integrated with access control systems or wireless PDAs.

DVR's are often optimized to make the job of law enforcement easier. Choosing a digital video recorder depends on the needs of the person looking for the system. Digital video recorders can be set up with DVDs or external hard drives to archive information and videos from past weeks, months, and years.
How Digital Video Recorders Work
Digital video recorders work in conjunction with congruent surveillance systems. A coordinating camera with similar capabilities transmits an image and/or audio to the digital video recorder, which stores video and sometimes audio on integrated or removable storage. This video can then be reviewed directly from the digital video recorder to a television or through a connected computer. Review often includes the capability to edit video, sharpening facial features and zooming in on characteristics relevant to forensic technology. Video can be transmitted from multiple cameras to a single digital video recorder. This type of system allows for more efficient surveillance and recording times of over three months at a time. From a computer, digital video may be monitored from remote locations, so even when on vacation, homeowners can keep an eye on their houses and business owners can check in on their businesses. Two-way voice communication can also allow for business owners to manage their businesses remotely, conversing with the people that they leave in charge.
Overall, there is no value which can possibly exceed the safety of a home or business. Making an investment in a good DVR can help to protect the items are people which you hold most dear.
