AI-powered NVR for home and small business

The Synology DVA1622 is a 2-bay desktop NAS designed for intelligent video surveillance. It runs on an Intel Celeron J4125 processor with 6GB of installed DDR4 memory and supports up to 16 camera channels. The diskless unit accepts two 3.5-inch SATA hard drives for a maximum raw capacity of 36TB. It provides local deep-learning analytics for people, vehicle, and license-plate recognition.

Sustained analytics workloads and thermal limits

The Intel Celeron J4125 handles continuous inference tasks such as face recognition and intrusion detection without relying on cloud processing. During active operation the system draws 19.93 watts and drops to 4.02 watts when drives enter hibernation. The operating temperature range spans 0°C to 40°C, allowing deployment in typical indoor environments while the fan manages heat from prolonged analytic workloads.

Diskless setup with single memory slot

Installation requires sliding two 3.5-inch SATA drives into the front bays and connecting power and network cables. The single DDR4 SODIMM slot is already populated with 6GB, so memory expansion means replacing the module rather than adding a second stick. USB 3.0 ports allow quick backup to external storage. Buyers who need more than two drive bays or redundant power supplies should consider a larger chassis.

Questions about this item

How much power does the Synology DVA1622 draw when its drives are active all day?

The unit consumes 19.93 W during access and drops to 4.02 W when the drives enter hibernation, so continuous operation stays under 20 watts.

Which drives must I supply myself for the two 3.5-inch SATA bays?

You need to provide 3.5-inch SATA hard drives; the system supports up to 36 TB total across the two bays in RAID 0, RAID 1 or JBOD.

Will the Intel Celeron J4125 and 6 GB DDR4 handle my existing IP cameras on the same network?

The four-core J4125 processor and 6 GB of DDR4 memory run Synology's deep-learning analytics for up to 16 channels, so existing cameras can be managed alongside the new NVR functions.
