New Hanwha NVRs apply AI technology to non-AI cameras

Chertsey, Surrey (UK)

The 5 new Wisenet P series AI NVRs just launched by Hanwha Techwin are able to apply AI metadata to images captured by most non-AI Wisenet cameras, allowing users to quickly and accurately search for people and vehicles.

The licence-free Deep Learning AI video analytics onboard the NDAA compliant NVRs offer a wide range of search criteria including, for example, looking for people of a certain age group or gender, as well as whether they are wearing glasses or carrying a bag. Similarly, a search for vehicles can be narrowed down to those of a particular colour and whether they are a bicycle, bus, car, motorbike or truck.

The NVRs can also be set up to trigger real-time alarm notifications if an object is detected.

Selected bullet, fixed, PTZ, 360° fisheye, multi-directional and thermal cameras from the Wisenet X, P, Q and T series, are among the long list of cameras supported by the new NVRs. In addition, as is the case with 32 and 64 channel Wisenet X NVRs, the new devices are able to support all the features built into the Wisenet P series AI cameras, including the classification and detection of faces and licence plates.

Operators can take full advantage of the NVRs’ functionality with the help of UX 2.0, a brand-new user interface which offers zoom in/out and drag & drop support and a timeline preview feature, as well as enabling all event settings to be edited in a single window.

The NVRs feature WiseStream II complementary compression technology which improves bandwidth efficiency by up to 75% compared to current H.264 technology, when combined with H.265 compression. The ability of the NVRs to support cameras which are dual streaming video at different resolutions, can further reduce bandwidth requirements.


The NVRs SATA HDDs are supported by Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T), which detects and alerts operators to any possible imminent hardware failures. Offering N+1 failover support, the NVRs also feature Automatic Recovery Back-up (ARB) to provide continuity of recording and remove the risk of video evidence being lost. ARB facilitates the transfer and seamless storage of the images stored on a camera’s SD card if communication between one of the NVRs and a Wisenet camera is disrupted.

In addition, the new PRN-6405DB4 NVR is equipped with a dual switched-mode power supply (SMPS), to provide continuity of recording for mission critical applications.

Security personnel can apply bookmarks to prevent important video from being overwritten, with the NVRs programmed to automatically delete the bookmarked video after a defined time period to ensure compliance with GDPR.

Easy to configure

The installation time of the new NVRs is minimised by the ability of engineers to remotely connect to the NVRs. This is achieved via a smartphone or tablet without having to set up a complex network by using P2P and unique QR product codes. Furthermore, the NVRs can be easily configured to match an end-user’s requirements with the help of an intuitive interface and installation Wizard.

“The accuracy of the Deep Learning AI video analytics incorporated into these new NVRs provides security personnel with a powerful tool to detect and track people or vehicles that may be involved in criminal activity”, said Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe. “By eliminating false alarms which can occur when standard motion detection technology or sensors are being used to detect activity, the NVRs significantly reduce time wasting and allow security personnel to focus on responding to real incidents and emergencies”.
