DVR stands for Digital Video Recorder. A security camera with DVR technology has the ability to retrieve the video from an analog camera and convert it promptly into digital format. Thereafter, it is recorded on a hard drive.  The reason why DVR security cameras are ideal for home security is that they require very little maintenance. As a homeowner, we understand that you’re concerned about the safety of your house but you can’t spend all your time maintaining security cameras. That’s why we recommend you to buy security cameras with DVR.
