The age of recording video images through VCRs is long gone. What we now have at our disposal are devices that exceed the features of the VCR technology by far. The fairly simple recording of video images has now evolved to systems that are equipped with a multitude of advanced functions. Digital video recorders (DVRs) are now widely used in both home and business applications. We can also find DVRs with very advanced features in security applications as part of CCTV systems. A CCTV DVR system exceeds previous video recording options in many aspects, as its multitude of advanced features enable it to offer a wider range of services. Video searches by date, time, event and camera are just an example of what the advanced technology of a CCTV DVR can do. In addition to this, a CCTV DVR provides enhanced control over frame rate and quality, which allows for the optimization of disk space usage. Furthermore, should the disk space be exceeded, the CCTV DVR can be set to overwrite older footage. This system can also be connected to the Internet or a LAN network so as to allow security footage to be accessed from a remote location using a computer. When you need to purchase a CCTV system, either for your business or for home use, you have to pay close attention to the kind of CCTV DVR that you choose as part of the kit. We could go as far as saying that the choice of digital video recorder for a security application is more important than that of the camera itself. Of course, there are many choices available when choosing CCTV cameras, but an informed choice of the CCTV DVR is very important. There are many aspects to consider when purchasing a CCTV DVR and what it basically comes down to is making the right choice so as to meet your particular needs and demands while trying to keep the budget as low as possible. Before making a choice of CCTV DVRs you need to look into some important details such as the resolution and quality that you want, the recording options, footage accessibility, the technical support offered by the supplier and, why not, the price tag that the product comes with. One of the most commonly used recorders in surveillance systems is the 4 Channel DVR, which has more advanced features than the traditional DVR used in home applications. The 4 Channel DVR is used with peripherals such as cameras and computers. Motion detection, data searching, audio and video compression and network backup are just some of its most important added features. The 4 Channel DVR can be connected to up to four cameras and allows real-time access to surveillance footage on the Internet irrespective of your location. This type of recorder also supports the use external media, such as optical disks or hard drives. As has been said before, the features of the CCTV DVR are often more important than those of the camera or other accessories. The use of a 4 Channel DVR in your surveillance system will insure high quality videos, as well as enhanced playback.
