[Tutorial] How to use Vcam?


The Vcam mobile app can turn your mobile device into a network camera. With the Vcam mobile app, you can record any moment around you to your VioStor NVR. The Vcam solution provides a great way to deploy a home surveillance system without purchasing expensive IP cameras.

Press the Blue Button to enable recording. If the button turns red then it is ready to record.

Please go to “Surveillance Settings” > “Camera Settings” > “Camera Configuration” > “Add” or click the “” to add the Vcam camera.

Please uncheck the option “Search camera(s) automatically” and click “Next”.

Please enter the camera configurations as followed, then click test to check the connection between the camera and Surveillance Station.

On this page, you will see the “Schedule Settings.”  On the table, 0~23 represents the time period. For example, 0 means 00:00~01:00, 1 means 01:00~02:00. You can set a continuous recording in any period that you want.

Then you will be able to confirm the settings on the next page.

After you have added the network cameras to the NVR, you can check the monitoring screen in. You can observe that the NVR IP Address is shown on the upper-left side. If the NVR IP address is not shown, this means that the connection has not been successfully established.

  3. Due to hardware & network limitations, the real “Frame rate” and “Bit rate” may not reach the number you set on your mobile device.
