When installing a CCTV surveillance system, one of the biggest decisions is choosing between a DVR (Digital Video Recorder) and an NVR (Network Video Recorder). Both systems record security footage, but they work differently and are compatible with different camera types.
Understanding the differences between DVR and NVR systems will help you choose the right solution for your home, office, shop, apartment, or commercial property.
