The DVR, or the Digital Video Recorder or also called a personal video recorder, is that device that records your videos into a digital format towards disk drives or some other forms of mediums. DVR often includes those set-top boxes that are stand alone, as well as those software intended for personal computers which basically enable video captures and playbacks to and from a certain disk. Presently, consumer electronic manufacturers began offering televisions with a DVR software and hardware that is built in directly to the television. Likewise, DVR has also become a main way for the CCTV companies for those surveillance records, because these said recorders provide longer recording times compared with those previously manufactured VCRs. More often than not, a DVR can make a very reliable security DVR.

History of the Digital Video Recorder- On July 8, 1965, those hard-disk based recorders were tested, when CBS, a television and radio broadcasting company, explored some possibilities for an instant frame and rewind technology intended for sports broadcasting. In 1967, the very first hard-disk based video recorders were introduced commercially thru Ampex, an American based electronics company that was founded in 1944. The pioneering video recorder models, the HS-100, can record composite analog videos into fourteen-inch diameter hard disks thru FM modulations. The said hard disk drive can store videos for only thirty seconds, but could still record continuously. Aside from that, it also has playback features that enable the user to play back a certain video twice its normal speed down to its steel frame.

In 1985, David Rafner, an employee from Honeywell’s Physical Sciences Center, described the first drive-based digital video recorder that was designed for personal and home television recording, time slipping, as well as commercial skipping. The US Patent 4,972,396 primarily focused on multi-channel designs to gradually allow simultaneous and independent recordings and playbacks. Over the years, manufacturers for digital devices have anticipated future developments of a digital video camcorder, describing possible applications like streaming compressions, captioning, editing, multi-channeling, security monitoring, remotely piloted vehicles, and military sensor platforms.

Aside from the basic personal and home use of a digital video recorder, a DVR is also very important, as far as security applications are concerned. There are actually some digital video recorders that are configured specifically for some physical security applications to record video signals coming from closed circuit TV cameras, mainly for documentation and detection purposes. Most types of digital video recorders that are used primarily for security purposes is the mini DVR. Aside from recording video footages, a digital video camcorder can record also audio. Digital video recorders have greatly evolved into devices that offer rich features while providing services that exceed those simple recordings of video images that are previously done with the use of the VCRs. Likewise, the DVR CCTV systems provide advanced functions over the VCR technologies, including video searches by date, time and event. A digital video recorder can also control the quality and the frame rate, thus optimizing disk usage. Furthermore, the digital video recorder can also overwrite even the oldest security footages, especially when the hard disk becomes full.

There are really a lot of advantages of having a digital video recorder. If you wish to have a device of you own, you can try visiting your local digital device manufacturers and inquire about these helpful and rich-featured digital devices. A lot of brands and available, so choosing which one is better for you is not that difficult.
