With the Super-HD, high megapixel count Q-See 5MP QTN8521B IP bullet you get the new technical leader for standard commercial, industrial and enterprise deployments. This cameras reliability, quality, clarity, ease of installation, and neat design is second to none and includes support for the latest H.265 compression standard.  In addition to these great new technical add-ons this camera supports smart image manipulation technologies to improve dramatically the image displayed and recorded.

Useful for essentially all short and medium range applications this camera and its earlier siblings has been deployed by the millions world over. With a close to 90° angle of view it is useful for covering offices, entrance halls, and other small areas and front and rear residential yards. It offers extremely high definition images and can be relied upon like no other camera for its price point.






Smooth 20 fps @5MP and 30 fps @ 4MP


Advanced compression

One concern with the very resolution cameras is their increased network bandwidth and storage requirements. 4K is essentially 400% more dots than standard 1080P High Definition cameras. Therefore bandwidth, processing and storage requirements are likewise 400% larger. To combat this problem the QTN8521B and QTN8522D cameras support the high compression H.265 CODEC. This reduces bandwidth and storage needs by 50% when compared to H.264.




Advanced image improvement




Smart apps and software








Match the Q-See QTN8521B with the next generation Network Video Recorders form Q-See like the QT878, QT816 and QT8732/64 for advanced video smart analysis, remote alerts, storage and plug and play setup.
