DVR (Digital Video Recorder) and NVR (Network Video Recorder) are both used for video surveillance systems. The main difference between the two is how they process and store video data.

DVRs process the video data on the device itself, converting the analog video signal into a digital format for storage on a hard drive. DVRs typically connect to cameras via coaxial cable and the video is viewed through a TV or monitor.

NVRs, on the other hand, do not process video data. Instead, they rely on network cameras that have built-in video processing and compression capabilities. The video data is transmitted to the NVR over an IP network and is stored on a hard drive for later viewing.

In summary, DVRs process and store video data locally, while NVRs store video data that has been transmitted over a network.

A 1080p CCTV camera is a security camera that records and outputs video with a resolution of 1920x1080 pixels. The "1080p" refers to the number of vertical pixels in the image, which is 1080, while "p" stands for progressive scan, meaning that each frame of the video is captured and displayed in a single pass. This is in contrast to interlaced scanning, where each frame is divided into two fields that are displayed alternately.

1080p is considered a high-definition (HD) resolution, and it provides clear and detailed images compared to standard definition (SD) cameras. A 1080p CCTV camera is suitable for many surveillance applications and is often used for home and business security, as well as for monitoring public spaces.
