Aren't NVRs and DVRs the same thing?

Published by Marie on March 20, 2015 3:43 PM

While you may be more familiar with the term DVR (digital video recorder), a main component of CCTV analog systems, NVRs and DVRs have different uses and are not the same thing.

Both a NVR and DVR are used to record and store video files from a security camera. Network video recorders (NVRs), however, are used with IP systems. NVRs are designed to work with the digital file format new IP cameras use to send and record video. A NVR, like the Milestone Husky M30, comes preloaded with video management software to help you manage and view your system.


A DVR, on the other hand, is older technology designed for use with CCTV analog surveillance systems. DVRs also come with system management software, and allow you to view your cameras. DVRs won't work with IP cameras, so you won't be able to easily add an IP camera without upgrading other parts of your system too.


As many organizations upgrade older CCTV systems with IP products, you can transition to hybrid products that work with both IP and analog cameras. A hybrid NVR, like the Milestone Husky M30 Hybrid, can connect to both IP and analog cameras, giving you all the benefits of an IP system without the cost of replacing every single camera.

You also have the option of using a video encoder instead of a hybrid NVR. Video encoders take the signal from analog cameras and turn them into the digital format used by a NVR so you can connect analog cameras to an IP system.
