What are the differences between DVR and NVR?
DVR and NVR systems differ mainly in camera type, video processing, and flexibility. DVR uses analog cameras and processes video at the recorder via coaxial cables, making it simpler and more affordable. NVR uses IP cameras that process video at the source and transmit it over a network, offering higher video quality, easier scalability, and better remote access.
