DVR (Digital Video Recorder) systems are traditional camera surveillance systems using analog cameras, coaxial cables, and a DVR recorder. The analog cameras connect to the recorder through the coaxial cables, transmitting unprocessed video signals. Once the signals reach the recorder, they can be processed and made available for digital viewing.

DVR and NVR surveillance systems use different types of cameras, shaping how each system operates. DVR systems use analog cameras that connect to a DVR using coaxial cable. The video signals from the cameras are converted from analog to digital by the recorder.

The main benefit of a CCTV DVR camera system is the cost. DVR systems are significantly more affordable than NVR systems, mainly due to the lower cost of analog cameras. This savings is especially appealing if you’re unsure about incorporating Wi-Fi into your security network.

The number of cameras, or channels, that a recorder can support depends on the specific model. Swann DVR recorders can support anywhere from 4 to 16 channels.

The Swann Security app for iOS or Android allows you to access live or playback video wherever you are. NVR systems come with a hard drive to locally store (usually up to 2TB of) data. There is also the option to back up some of the camera footage on the cloud.

Swann DVR recorders have massive 1-2TB hard drives, allowing for footage to be stored for up to one year at no additional cost to you.

You can permanently save images and video in your personal Dropbox account in the cloud, or transfer footage to a USB memory stick or hard drive for safekeeping.

No. There are no ongoing fees to install and operate your system and there is ample free local storage included with every Swann DVR.

Multi-stream wired surveillance systems typically require broadband internet connection at the premises where the cameras are located with upload bandwith of 2Mbps or greater.
