2-bay NAS/Network Video Recorder. Synology Deep Learning NVR DVA1622 Purchased last year, but I am selling it because I switched to a different system. The HDDs have been removed, so only the chassis is available. Only the main unit and AC adapter shown in the photos are included. It has various functions for surveillance camera use. It can identify people with facial recognition and recognize license plate characters. It is ideal for those who want to use AI-powered features such as alerts when multiple people stay for a certain period of time. Currently, it costs about 120,000 yen on Amazon, and about 105,000 yen with points on other sites. - Brand: Synology - Model: DVA1622 - Type: Network Video Recorder - Number of Slots: 2 - Power: DC 12V 5A Thank you for viewing.
