QNAP Security Releases VioStor Firmware V3.5.2 Improving Multi-Streaming, Joystick Controls and Network Camera Support


Taipei, Taiwan, December 22, 2011 – QNAP® Security, leading dedicated Linux-based NVR solution provider, introduced improved video experience with NVR firmware upgrade VioStor 3.5.2. It offers enhanced multi-streaming, USB joystick controls and support for the latest network camera models. The upgrade includes greater multi-streaming functionality for high-resolution archiving and live viewing at lower resolutions. Users can control PTZ cameras with a USB joystick remotely — not just locally — for powerful monitoring capabilities from any off site location.

"To provide security managers with smooth live view experiences, we boosted our ability to record high-resolution footage in H.264, while creating a second stream at lower-resolution stream for viewing or even a third stream at medium-resolution available on high-resolution cameras," said Andrew Yu, product manager of QNAP Security. "The QNAP NVR adds support for more than 100 new network cameras, giving customers greater freedom to design best-of-breed video solutions."

VioStor stand-alone NVRs offer remote monitoring from multiple servers, supporting up to 128 channels of video. The embedded NVR provides rich network video functionality, such as intelligent video analysis, advanced event management and watermarking. Security managers never miss a thing with detailed E-maps on monitoring page, along with receiving real-time reporting through text messages and emails.

The VioStor NVR combines storage and security monitoring functionality in one comprehensive package. To download the VioStor 3.5.2 firmware upgrade, please visit
