In short, DVR-based CCTV systems are relatively simple set-ups owing to older technology; whereas, NVR-based CCTV systems are the latest technology, and better for business and complex usage. DVRs are used with analog CCTV cameras while NVRs are used with internet protocol (IP) cameras. In a DVR, the video is encoded and stored in the DVR, whereas with an NVR, this happens in the camera and the videos are then stored in the NVR for remote access. A DVR-based security system is usually wired and each camera needs to be connected directly to the DVR. NVR-based security systems are wireless and all cameras can be connected to a single network. In a DVR-based system, you\u00e2\u20ac\u2122ll have to consider extra wiring for recording audio. NVR CCTV systems are highly flexible and easy to scale up when your requirement grows larger.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t
