Surveillance Camera DVR, NVR, IVR

Surveillance camera systems rely on different types of recording devices to store and manage video footage. The three main types are DVR (Digital Video Recorder), NVR (Network Video Recorder), and IVR (Intelligent Video Recorder). Each of these systems serves a specific purpose based on the type of cameras used and the level of functionality required. DVRs work with analog cameras and process video signals before recording, while NVRs are designed for IP cameras and store video data over a network. IVRs, on the other hand, incorporate advanced AI-driven analytics to enhance security monitoring.

Choosing between these systems depends on factors like video quality, ease of installation, and storage capacity. DVRs are cost-effective and ideal for legacy systems, NVRs offer higher resolution and remote access, and IVRs provide intelligent features like facial recognition and real-time alerts. Understanding their differences helps businesses and homeowners implement the right surveillance setup for their security needs.
