DVR(digital video recorder)also known as a personal video recorder records directly to a disk or hard drive instead of to a video tape of sorts.
It can be found on most computer software as well as being in the form of stand-along box units for television and film. You can also use them as a cost effective way for security by getting DVR cards with up to 8 camera connections on them. So, then you can mount security cameras all around your property and record directly onto your PC. By this method you can capture several days worth of video footage from several cameras into your DVR system on your computer.
CCTV security system organizations also use DVR in their surveillance systems since DVR is able to record for extended lengths of time. It provides a clearer picture, allowing for better quality results. DVR is therefore used by banks, car dealerships, retail stores, and especially at mini-markets which are a prime target for crime. Such recorder systems are helping combat crime by providing excellent images of people committing crimes. So, in case you want to find out what is happening in your office you can hook your DVR surveillance system into the Internet and see live images. You can also store the video for three months or more. A typical DVR surveillance system has the essential components including motion sensors, multiplexer, image zoom controls; color quad processor and CCTV camera connections.
Most of such surveillance systems have image zoom controls that can move and turn from side to side ensuring that you don't have to put more than two cameras in a room. So you need not record everything for 24 hours, as the device will only switch on when there is activity in the area being monitored and also save on disk space. Every motion in the DVR systems can be separated into an image in common formats like jpeg which makes recognition of faces or movements easier.
You can then store the videos according to time and date for sequential retrieving. Some of these systems also offer audio recorders to listen to conversations taking place in a room being monitored. So, it comes as no surprise that many of the organizations, malls, banks and homes are installing DVR based security systems. In the near future, more of such technological enhancements will make the DVR security systems even more effective and with possible lower prices. ink.Labels: cctv, cctv vs dvr, dvr, dvr systems, security systems, security tv
