DVR Security Camera

A DVR security camera can prove to be an invaluable investment. DVR stands for digital video recorder. Such a device is designed for the purpose of recording programs shown over cable, satellite or broadcast television, but more importantly, for the capturing of images used for security and surveillance measures. The clear images and expansive footage that such technology captures makes the capturing of wrongdoers easier and helps to keep crime levels down.

Before technological advancements made DVR and equipment such as a CCTV digital video recorder possible people had to rely on recording onto videocassette tapes via VCRS. This method worked but videocassette tapes would fill up very quickly which has proved problematic to surveillance cameras as often they are continually recording. Eventually time lapse recorders were put into use. These would record one frame or less a second, which went a long way into conserving space on cassettes. However, there are many disadvantages to this form of recording. Crimes can happen very quickly, and time lapse recorders are only able to capture some of the action. Important details can be left out simply due to the recorder skipping over important seconds, such as a criminal turning towards the camera, or the flash of a license plate.

In order to conserve space, video tapes are recorded over again and again which not only serves to reduce the quality of the film, but causes increased wear and tear on equipment causing expensive pieces to wear out rapidly. Along with the fact that plastic tapes are prone to breakage, they are also inconvenient due to the fact that someone must always change a tape as soon as space runs out. In order to make tapes more efficient, they are hooked up to device known as a multiplexer. Simply put, this is a device that is designed to hook up to multiple cameras at the same time, and record images from each one. The problem with this method is all images that are input into the system show up very small, so that all can fit on one screen simultaneously, yet there are no means of making them larger. This is an efficient method, however, not very effective as many times the images are simply to tiny to see any details. Surveillance methods have come a long way over a short time and in many cases have completely replaced time lapse recorders and multiplexers with devices such as the DVR security camera.

Surveillance measures are important in case of crimes or actions by dishonest employees and for this reason methods for recording must be reliable and efficient. Multiple solutions have been enacted upon older methods, and eventually, in the early nineties the technology was invented that gave rise to the DVR security camera. Devices were created that were commonly controlled with a system of remotes and proved to be very user friendly, however, as the technology was still relatively new, such recording methods were not always able to be relied upon to work continuously. Over time, DVR recording devices such as a CCTV digital video recorder, were used in conjunction with personal computers, which has given rise to more reliable methods and the explosion of popularity in regards to advancements in efficiency and value. Those who choose to employ the use of the devices can now trust that they are choosing to make a wise investment choice.

Those in the market for a DVR security camera should do adequate research before running out and investing in a system. Over a short time virtually all security businesses have begun selling DVR devices such as CCTV digital video recorder with the common belief that all the devices are capable of doing is digitally recording video. However, the equipment is capable of much more than merely capturing images. One must refrain from running out and purchasing just any system. The effectiveness depends on many factors and should be put together by a team of experts. There are many factors that go into building surveillance measures and should not be done quickly or flippantly, as errors can cost money.

Savvy shoppers should know how many people have worked on a system, as many times, if only a few people have put the system together the end result might not hold up to standards. A DVR is unique in that it records directly to the hard drive of the computer it is connected to. Hard drives are light years better than videocassettes due to the fact that substantial amounts of information and images can be stored, the systems are completely automatic meaning there is no need for someone to constantly change out a tape, and the quality of the images recorded is very good. Digital recordings allow for immediate access and ease of viewing as specific portions can be viewed immediately and simple to find.

Digital recording devices have become very important and many companies rely on them when it comes to security measures. Crimes can be solved and even prevented when proper measures are planned out and wise investment decisions are made. Devices such as a CCTV digital video recorder are easy to operate and can provide hours of digital surveillance footage that can be counted on to show as much detail as possible which enables investigators to solve crimes quickly and efficiently. Technology has allowed for advancements that can help to provide safety for store owners and customers alike, as the Scripture says, "And thou shalt be secure, because there is hope" (Job 11:18).
