The NVR has a menu bar at the top of the page. On a PC screen
this menu bar will normally show the menu names, though on a mobile
device a 
icon must be tapped to reveal them.
Before any option is selected, the page below the menu bar will be blank.
This menu allows selection of live video/audio camera streams. The names are listed in the form Camera Name(Stream Description) so there can be more than one stream per camera.
On selecting the live stream, the video will be shown with a
icon and a selector just below it. The selection option is the maximum latency in seconds. You can set this to the lowest setting where the video remains stable. The lowest usable setting is dependent on various factors and won't necessarily be the same for all your cameras.
If two-way audio is enabled, a
button and a device selector will also be below the video. Select the required audio input device and click the
, click it again to turn audio output off.
You can zoom in on the video by using the mouse wheel on a PC, or pinch zoom on a mobile. Mouse down and drag will pan the zoomed video while touch and move does the same on mobile. This is distinct from PTZ operations which can be done on suitable cameras.
The last option on the Select Camera menu is Multi Camera View. This shows one stream
from each camera in the configuration. The default stream shown
for a camera will be the one selected as Default On Multi Display.
The camera streams can be switched by clicking the
button at the top left of the page and changing the selection.
Each video on multi camera view will have the latency chasing setter below it. Any cameras with two-way audio enabled will also have the
Mouse wheel zoom and mouse down drag pan functions, and their mobile counterparts can be done on each of the videos.
This menu allows selection of recordings made on camera streams. The names are listed in the form Camera Name(Stream Description). On selection, the latest recording on that stream will be shown. Earlier recordings can be selected from the date control and Motion Events selector in the top left of the page. A warning box will appear if there are no recordings for the selected stream.
