Are All Security Cameras Compatible With DVRs? It’s a common question for anyone exploring surveillance setups.

In this post, we’ll break down how DVR systems work, when the internet is (and isn't) necessary, and what you need to know before installing your next setup.
A DVR (Digital Video Recorder) is a device used to record footage from analog security cameras. It stores video on a hard drive and allows users to view, play back, or export recordings.
