Hikvision DS-9632NI-M8. The DS-9632NI-M8 provides 32 IP recording channels with eight hard-drive bays. It suits systems that need more storage expansion than a compact recorder, with incoming video bandwidth rated up to 320Mbps.
Two network interfaces and multiple local display outputs support integration into a larger installation. The recorder supports H.265+ compression where the cameras and settings are compatible. Plan storage around the required retention time, resolution, frame rate and recording schedule rather than drive count alone.
