exacqVision Edge is a version of exacqVision Server that runs directly on supported camera models and only connects to, and records video from, the camera it is hosted on. Cameras running the exacqVision Edge, or Edge+, application must be configured for the GMT+0 time zone.
Because the server application runs directly on the camera, the Time Zone field cannot be configured from a connected exacqVision Client, but will need to be configured through the camera’s web browser interface.
However, the Time and Date fields can be configured from within the exacqVision Client and should be configured to GMT+0 rather than the current time where the camera is located.
Because the server application is running directly on the camera, the application tells the camera to use the loopback address of 127.0.0.1 as its time source, effectively telling the camera to look to itself for its time. Enabling the Time Server setting will not correct this. But you may override this behavior by selecting the Enable Override option and entering the URL or IP address of an NTP source of your choice. This will override the localhost setting, forcing the camera to use a trusted network time source. For more information on NTP sources, refer to Explaining NTP.
The below example, from an Illustra camera, illustrates that the Time Zone will be set to GMT+0 in the camera. You will need to restart the Edge Server application on the camera if changing this after it has started.
When connecting the exacqVision Client to an exacqVision Edge Server instance, the Client will display the time of the client workstation in the OSD unless you configure the OSD to display Timezone information, in which case it will display the camera’s time of GMT+0.
The two example images below illustrate this effect. With the Timezone checked, the client time shown in the bottom-right of the window’s status bar is reflected in the camera OSD time. When the Timezone field is unchecked, the camera OSD time will match GMT+0 rather than the local client time.
