TS-AI642-8G 8-core ARM Cortex 64-bit Processor ( 4-core Cortex-A76 2.2 GHz + 4-core Cortex-A55 1.8 GHz ), 8 GB on board (non-expandable)

The next-generation TS-AI642 AI NAS is specifically designed for AI-powered video and image recognition applications. Adopting the 64-bit ARM Cortex-A76/-A55 SoC octa-core processor with up to 6 TOPS NPU (Neural network Processing Unit), the TS-AI642 not only tackles image processing and analysis tasks, but also offloads CPU workloads when running AI applications to reduce system operation power consumption. With powerful computing performance, high-capacity storage space and flexible I/O expandability, the TS-AI642 allows enterprises to easily deploy an AI NAS solution for video surveillance, image recognition, and face recognition applications.


  • AI computing performance of 6 TOPS NPU

    With a built-in NPU (Neural network Processing Unit) processor, the TS-AI642 boosts performance for high-speed face and object recognition.

  • 2.5GbE is a must!

    2.5GbE provides higher transmission speeds with existing Cat 5e cables, making file backup/restore and media conversion smoother.

  • PCIe Gen 3 Expandability

    Install a 2.5/5/10GbE adapter, QM2 card, or USB 3.2 Gen 2 (10Gbps) card to increase application potential.

  • Professional surveillance NAS solution

    QVR Elite allows you to deploy up to 64 channels (2 channels are included for free).

  • Dual 4K HDMI Output

    Use two screens for surveillance or 4K high-resolution video playback.

  • ARM hardware transcoding

    Supports ARM NEON technology that accelerates video processing for a better media experience.

Expand storage capacity up to 18 hard drives

The TS-AI642 supports a storage capacity of up to 110 TB by installing six 3.5-inch 22 TB hard drives in RAID 5. By connecting a TL-D1600S QNAP storage expansion unit, you can add an additional twelve hard drives to the TS-AI642 to achieve up to 350TB storage space to meet growing storage requirements. Or connect TR Series storage expansion units to add Hardware RAID protection for expanded storage.

  • Storage capacity

    110 TB

 1. Install six 3.5-inch 22 TB hard drives in RAID 5 on TS-AI642 and six 3.5-inch 22 TB hard drives in RAID 5 on TL-D1600S.
2. The storage expansion unit can only be used as an individual storage pool or volume on the NAS. Its storage pool/volume cannot be combined into the connected NAS. NAS applications cannot be installed on the storage expansion unit.


NPU accelerates on-device AI performance. 3x Faster face recognition.

Adopting an NPU (Neural network Processing Unit), the TS-AI642 boosts QNAP AI Core (the AI-powered engine for image recognition) performance for high-speed face and object recognition.

  • QuMagie photo management

    NPU greatly accelerates image recognition performance when uploading pictures in QuMagie, realizing intelligent classification.

    200% performance boost in image recognition*

  • Qsirch full-text search engine

    NPU accelerates AI OCR image recognition technology to make capturing text in images more efficient.

    20% performance boost capturing text from images with AI OCR*

  • QVR Face Insight facial recognition

    QVR Face instantly recognizes faces and runs analytic tasks within 0.2 seconds. NPU allows more IP cameras to be analyzed at the same time.

    10 cameras for real-time attendance management analytics

  • QVR Human people counting solution

    QVR Human provides real-time counting data and analytics, and NPU allows more IP cameras to be analyzed at the same time.

    3 cameras for real-time analytics

 Note: By comparing with the same-grade 6-bay NAS.


Efficient image search with AI photo management

TS-AI642 is the best photo and file storage center. Store and organize thousands of photos and find them anytime you want with powerful AI image recognition.


Smart surveillance

The TS-AI642 provides a professional surveillance NAS solution, compatible with 6,000+ IP cameras of 190+ brands and thousands of ONVIF network cameras. Full HD (1080p) surveillance video recordings of 2 cameras can be stored for 2 years.

All-in-one surveillance

Say goodbye to expensive and complicated PC NVR. QNAP’s integrated surveillance NAS solution offers a subscription licensing solution or perpetual licensing solution for flexible deployment based on your needs.

Connect to HDMI monitors

The TS-AI642 has dual HDMI output for direct surveillance video playback to two monitors, removing the need for a dedicated workstation.

Surveillance failover

Install the high-availability QVR Guard app to automatically takeover recording tasks if a QVR Pro server fails.

Next-generation 2.5G NAS with power-efficient ARM SoC 8-core processor

The TS-AI642 adopts the ARM Cortex 64-bit-A76/A55 SoC octa-core processor with ARM Mali-G610 MC4 GPU, offering excellent computing performance at a low power comsumption. TS-AI642 has one 2.5GbE port and one PCIe slot for upgrading to 10GbE connectivity. SATA 6Gb/s drives are supported to deliver reliable read/write performance for hosting versatile NAS applications in offices.

    RAID Group


    To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, RAID TP, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected.
