DVR Systems


By Aurther Mclelland

DVR Systems what are they used for? How are they used? And do you really need one. Will to answer this questions and foremost the question that is the biggest question what is it used for. A digital video recorder (DVR), sometimes referred to by the merchandising term personal video recorder (PVR), is a consumer electronics device or application software that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device. The term includes set-top boxes (STB) with direct to disk recording facility, portable media players (PMP) with recording, recorders (PMR) as camcorders that record onto Secure Digital memory cards and software for personal computers which enables video capture and playback to and from a hard disk drive. A television set with built-in digital video-recording facilities was introduced by LG in 2007, followed by other manufacturers.

So let go over the history of them. Consumer digital video recorders Replay TV and TiVo were launched at the 1999 Consumer Electronics Show in Las Vegas, USA. Microsoft also demonstrated a unit with DVR capability, but this did not become available until the end of 1999 for full DVR features in Dish Network’s DISH player receivers. TiVo shipped their first units on March 31, 1999. Replay TV won the “Best of Show” award in the video category with Netscape co-founder Marc Andreessen as an early investor and board member, but TiVo was more successful commercially. While early legal action by media companies forced Replay TV to remove many features such as automatic commercial skip and the sharing of recordings over the Internet, newer devices have steadily regained these functions while adding complementary abilities, such as recording onto DVDs and programming and remote control facilities using PDAs, networked PCs, and Web browsers.

Hard-disk based digital video recorders make the “time shifting” feature (traditionally done by a VCR) much more convenient, and also allow for “trick modes” such as pausing live TV, instant replay of interesting scenes, chasing playback where a recording can be viewed before it has been completed, and skipping of advertising. Most DVRs use the MPEG format for compressing the digitized video signals. Video recording capabilities have become an essential part of the modern set-top box, as TV viewers have wanted to take control of their viewing experiences. As consumers have been able to converge increasing amounts of video content on their set-tops, delivered by traditional ‘broadcast’ cable, satellite and terrestrial as well as IP networks, the ability to capture programming and view it whenever they want has become a must-have function for many consumers.

How to use DVR recording systems for ghost hunting. DVR-Systems-For-Ghost-Hunting It is not possible to properly investigate a potential haunted location with only a few people. Occurrences do not always wait for people to witness them and using DVR systems for ghost hunters can help with documentation. A DVR system has cameras, infrared boosters, and a monitor to analyze the investigation. Ghost hunters can set cameras in rooms where the most occurrences are recorded. While investigators travel from room to room, the cameras can remain in one location. This can help in two different ways. One way using DVR systems for ghost hunters can help an investigation is to allow people to record an event that an investigator may witness. This can help substantiate a claim of a supernatural occurrence.

Another possible way that a DVR system can help with an investigation is by recording events when ghost hunters are not in the room. Whether ghosts are shy or just not able to collect the energy they need at the right time, supernatural events may occur when a room is vacant. Beginner ghost hunters use regular cameras to help record phenomena. This is beneficial, but it has downsides. Standard cameras need to be checked on occasion to change tapes and check battery levels. Depending on the length of the investigation, the tapes may need to be changed several times. Using DVR systems for ghost hunters eliminates this need. It is possible to record hours of events from multiple locations without the need of a tape. A monitor for a DVR system can allow an investigator to watch several rooms at once. One monitor can show five or six different cameras, and can let investigators know what is going on at any particular location.

After an investigation, ghost hunters need to be able to review the tapes to see what may or may not have occurred. Using a DVR system for ghost hunters will allow investigators to stop, enhance, or rewind what was recorded from a particular camera. It is also possible to move a tape frame by frame to capture even the slightest detail. Not all phenomena are ostentatious. Some of the events that occur may be subtle. It takes a great deal of energy for a spirit to move an object; the subtlest movements may exhaust them. Frame by frame viewing may allow investigators to catch those small movements. A chair rocking, a ball moving across the room or a faucet turning on may be the proof necessary to justify mystical claims. Using DVR systems for ghost hunters lends credibility to an investigation. It can help verify eyewitness accounts and record phenomena that occur even when no one is in the room. Enhancing a particular frame can determine whether or not an occurrence is supernatural. Sometimes there is a logical explanation for what is happening. When there is no logical explanation, than the tape can be analyzed. Whatever is left, however impossible will have to be the answer.

I have always been questioning the paranormal since I was a kid. Having lived all across America and in several countries overseas, I have heard story after story of this place or that place being haunted, and my curiosity always got the better of me. Always looking and seeing things I could not explain, my eye opener was when I was twenty and seeing a full body apparition standing in front of me made me more curious of what actually happens to us when we pass on. I aim to find the truth of what is out there. When I am not finding the truth I am usually taking care of officer business or fencing in the SCA (Society for Creative Anachronism, Inc.). Aurthur is also President (for business only) Chase Manger, director of Cheyenne Mountain Paranormal Investigations, co-owner of Front Range Ghost Shop and also severs 16 years army and has been Medical Retired. Having been station in places like Iraq, Korea, Fort Hood TX, Aberdeen Maryland, Fort Irwin CA and Fort Riley KS just to name a few this hole time caring what ever equipment he could care doing investigation on his time off in all thous places trying to learn what he could and how to be a better investigator. always learning on how to do thing better.
