How does digital video recording (DVR) differ from network video recording (NVR)?

• A. DVR is used for IP cameras and NVR for analog cameras
• B. DVR uses cloud storage while NVR uses local storage
• C. DVR is used for analog cameras while NVR is designed for IP cameras
• D. DVR has no recording capabilities, while NVR does

Answer: (C)

The distinction between digital video recording (DVR) and network video recording (NVR) primarily revolves around the type of cameras they are designed to work with. DVR systems are specifically engineered to accommodate analog cameras. Analog cameras capture video in a format compatible with DVR technology, which converts and compresses the video for storage and playback. On the other hand, NVR systems are tailored for use with IP cameras. These cameras transmit video data digitally over a network, which NVRs are capable of handling directly, allowing for enhanced video quality and remote access capabilities. This differentiation is vital because it influences how surveillance systems are set up and operated. The infrastructures of DVRs and NVRs are inherently different due to the camera types they support, which speaks to their capabilities in handling video resolution, storage needs, and the complexity of installation and configuration. Other options misrepresent the functionalities and compatibility of DVR and NVR systems, showing a misunderstanding of their operational principles and the technology involved.
