DVR, NVR, OVR…What does it all mean?

DVR, NVR, OVR…What does it all mean?  I just want to see my cameras!

Camera Systems are coming in all shapes and sizes these days.

The most popular camera systems are 8 cameras and under with the end goal to quickly see live video from ANY Device and EASILY find and locate recorded video clips to share with police.

The 3 typical configurations of camera systems are as follows:

  1. DVR (Digital Video Recorder):  Analog cameras with a simple to use interface for viewing live and recorded video.  Typically used for local, onsite recording and viewing.  Although analog camera signals have vastly improved in recent years with HD cameras, low quality analog camera systems are still very prevalent.  Quality for recording and playback of video is typically grainy, pixelated and hard to view.  Analog DVR’s require a direct cable from the camera to the recording device.

  1. NVR (Network Video Recorder) was established for network environments with networked cameras.   Whereas Analog camera system require wire from the camera to the recording device, a Network Recording system works similar to that of a typical network system.  The Cameras (devices) are connected to the network switches and are routed with IP addresses instead of a direct cable to the recorder.  This allows for a much more structured installation with camera locations expanded  buildings and multiple locations to easily bring all the camera viewing back to a single location.  It also allows for smaller systems to by connected together and quickly accessing cameras from around the world.

  2. OVR (Online Video Recorder)  This is a new platform that was established to bypass the local recording device.  This allows network cameras to be installed wherever an internet connection is available and be completely autonomous from a recording device.  All you need is power, internet connection and a recording account to get started.  This allows for less expensive, smaller systems that are very portable.


As in everything, Cloud Backup is integrated to camera systems.  Why not?  Some of your most important footage from security cameras have always been stored on a local drive onsite.  If there was an issue with the recording device or it was intentionally damaged or stolen, so was ALL your footage!!  This can be a risky maneuver for some installations or applications.  The cloud allows for seamless constant backup of your recorded footage for remote access of live and recorded video.  It solves that issues of dead equipment that causes you to loose old footage.  It also prevents damage or theft of your equipment that would cause loss of footage.
