New and Improved Features

Notes: Please note there are two network cards built into the NVR. If you use the NVR POE for your IP camera, when you add the IP camera to the NVR, you need to change the IP camera address to different subnet range. Forexample, NVR is Lan1, the IP address will like, and all other IP cameras directly connected to the NVR should be set to the address like 192.168.2.xxx;

When you add any ONVIF protocol camera to the NVR, please make sure you have changed the IP address of the ONVIF camera before you add it to the NVR, Lan 2 subnetif connects to NVR directly, Lan 1 subnet if it has own power or connects to POE switch. It is also required to add user name and password info for each ONVIF camera in NVR channel settings, even you have no password set in the camera itself, as NVR has no permission to change ONVIF IP camera address and couldn't access the camera without login credentials. _



The Doss IP NVRs are now smarter with baked in Intelligence features. On top of all that, they also now support higher resolution cameras!

Here's what's new with the IQ NVR range:

  • New Graphical User Interface The layout and usability on the new NVRs have been greatly improved over their predecessor, making navigating and finding what you want a much easier experience.

IQ Analysis

With more and more people now turning to CCTV surveillance for their security needs, its no surprise that new technologies are being developed and implemented to helpreduce the need for manual monitoring and the costs associated. One such strategy is the use of Intelligent Video Analytics (IVA).

The Magic of Intelligent Detection

IVA focuses on automating the video analysis of large amounts of data footage and security alerts, rather than having people monitor each camera manually. The software utilises a range of rules and algorithms to ignore any changes in lighting conditions or non-critical activity, andfocus on specific triggers to identify suspicious behaviour and objects.

A good example of Analytics would be its ability to alertauthorities of suspicious objects left in public places, like airports, and use facial recognition to help track downfugitives. It could also be used in Highway CCTV situations to capture and report a vehicle travelling in the wrong direction or performing an illegal turn. Even for the domestic home, Analytics could alert and monitor a trespasser crossing a property line. With every aspect of our lives being digitised, video footage will be increasingly tagged to these events. Imagine a person scanning a train ticket at a turn style. The scanning of the ticket and the footage from the CCTV camera will get put together and be readily accessible in real time or a month later.
