DVR (Digital Video Recorder)
What is a DVR and why do I need it?
it is known as a Digital Video Recorder it is a device or application software that records video in a digital format to a disk drive, USB flash drive, SD memory card or other local or networked mass storage device, you need a DVR to record and store footage from your analog camera so you can view the footage.
How it works is the recorded video is stored in a digital format ,such as AVI or MPEG, much like the data on a DVD. A closed circuit of analog camera is connected to a DVR device or PC with DVR capability. As the video footage (and possibly audio), is routed to the DVR device by a system of cables. The transmitted video can be routed to display on monitors, over a network to another device, or converted into a digital format and stored. All archived, or stored, video information is "stamped," meaning it is labelled to indicate what time and date it was recorded and which camera provided the input. This allows people easier access to both real-time and archived security data, we connect the DVR to your local network and install a client software on your computer or a app on your smartphone so you can watch real time footage or recorded footage from anywhere in the world.
