When it comes to security camera installation, there are two primary System technologies to consider: NVR (Network Video Recorder) and DVR (Digital Video Recorder). Both systems can operate through wired or wireless connections and support high-resolution video, including options ranging from 2 megapixels (1080p) to 8 megapixels (4K). The key difference lies in how they transmit and process video signals. DVR systems typically use analog cameras to transmit video using coaxial cables. In contrast, NVR systems are designed for IP cameras and use Ethernet cables to transmit both video and power via Power over Ethernet (PoE) technology. Due to their advanced features and flexible networking capabilities, NVR systems usually come at a higher cost than DVR setups.
Both NVR and DVR technologies are capable of supporting essential features such as night vision, infrared recording, and full-color functionality in low-light conditions. They can be deployed in both residential and commercial security camera systems, depending on the property’s specific requirements and budget considerations. The decision between NVR and DVR should be based on the installation planning: factors like the size of the installation area, desired video quality, type of cabling available, and long-term scalability.
