That means the NVR can only display two 4K cameras at a time, via live view or playback locally on the NVR. Keep in mind that other standard cameras, are also contributing to this decoding capability limit.įor example, the Admiral Pro 16ch v2 offers “2 x 4K, 4 x 4MP, 8 x 1080P 16 x 720p” It’s important to note, that this is for the live view only - the camera is still recording in the background and can be accessed on playback.įor the Radius 12.0, it’s important to check the decoding capacity of the NVR. This can create an issue where the NVR’s decoding spec is overloaded, causing the NVR to turn off the live view and replace it with a “No Resource” screen. Often they have a very high resolution, and do not offer a substream for the NVR to view while in multi-camera views. Most hardware decoding fisheye cameras offer unique challenges with live view on an NVR. Fisheye cameras in general are not ideal for gathering fine details, due to the large 360 FOV and details are most clear from the standard fisheye view zoomed in.Īnother note about quality, due to the nature of the lens, details in the “middle” of the frame, whether dewarped or not, are generally clearer than those on the edge. There is little difference in detail quality in software vs hardware decoding. Currently, the Admiral 8 Channel v3, The Admiral Standard 16 Channel v3, the Admiral Pro 16 Channel v3, the Admiral Pro 32 Channel v3, and our current Imperial line support fisheye decoding locally.Įven if your NVR does not support fisheye dewarping locally, you can still software dewarp from the Windows version of Viewstation and web interface, as well as SCW Go for Android and iPhone.Ĭurrently, the Mac version of the web interface, VIewstation does not support fisheye dewarping capability. The main downside, is that your NVR must support fisheye dewarping to do it via the local (HDMI) interface. The main advantage is that this only takes one camera slot on your NVR, and is more flexible as you can dewarp via live view or playback. Software decoding is performed by the NVR itself, it grabs the higher resolution fisheye view, and dewarps it using the NVRs CPU. With hardware decoding, this view is static, and can not be moved around after recording. Only the Radius 12.0 supports hardware dewarping, the Radius 5.0 does not. Hardware decoding is useful for NVRs that do not support software dewarping and useful to have a more permanent view in place. For example, if you record an ePTZ image, you can not move or dewarp it again to move the position. On hardware decoding, a camera has a static view. So for example, if you want to do a fisheye view and 3 ePTZ views, you would be occupying 4 channels on the NVR. record individual streams and act as individual cameras. Each of these channels will occupy a channel on the NVR. With hardware dewarping, the camera can dewarp the image itself, and send out multiple channels to the NVR.
