A digital video recorder (DVR) is a device that records and stores video in a digital format (using hard drives, USB memory, or other forms of mass storage) that was initially designed to record from analog sources but over time has started to incorporate digital sources.

What is a DVR?

A digital video recorder (DVR) is a device that is used to record video from analog (or digital) sources into a digital medium. Usually, this is a hard drive or USB memory format, although many formats can be used.

Many DVRs that are used for security functions operate on a closed circuit system, and some are also capable of recording audio. Note, however, that one-party audio recording is not allowed in all jurisdictions, so you should always consult the local laws before setting up audio recording equipment.

Why are DVRs important?

DVRs are relatively inexpensive systems compared to more modern network video record (NVR) systems. While using the most up-to-date and high-resolution cameras may be important for a business, it might not be in the budget for all businesses.

There are still many analog cameras in use today. The cost of upgrading an entire analog camera system might make it prohibitive to move from an obsolete DVR system to the state of the art.

However, it might not be necessary to upgrade your entire analog system to take advantage of modern video analytics. Solink is compatible with many analog security cameras. That means you can upgrade your security level with a lower upfront cost.

DVR systems are less prone to breaking down as they have fewer high-tech electronic components. Since they last longer than NVRs, the replacement cycle is longer.
