The recommended web browsers for an NVR L Series using firmware version 1.1.66 and above are:
Internet Explorer 11
The later versions of firmware for the NVR L Series now supports HTML5. This means video playback and video backup is now supported for browsers rather than just Internet Explorer 11. All features will still work with Internet Explorer 11.
It is recommended to update your NVR L Series to firmware v1.1.66 and above. Once the NVR is using a firmware 1.1.66 or above, it will allow a whole range of browser to be used to access the NVR's with full functionality.
The only limitation when using a browser other than Internet Explorer 11 is the NVR will only display a quad camera view on the camera display. The cameras shown in the quad display can be cycled through using the Quad display button.
If you use a browser that is not supported you may still get Live images but you may not get the playback function, as shown in the screen-shot below. If this is the case, it is recommend to use Google Chrome.
