This NVR requires a hard-wired connection directly to your router to operate. Supports all Amcrest WiFi and Wired IP cameras and limited compatibility with third-party brand ONVIF compliant IP cameras. The system will only work with Amcrest cameras/systems and support POE cameras. The monitor needs to have HDMI compatibility and needs to be connected with HDMI directly into monitor, if not users could experience monitor issues.
