Chapter 9. Troubleshooting
1. The monitoring screen did not display.
Please check the following:
A. Check if you have installed the ActiveX add-on when logging in the
monitoring page of VioStor. Set the security level to “Medium” or lower in
Internet Options of the IE browser.
B. VioStor is turned on and the network is correctly connected.
C. The IP address of VioStor does not conflict with other devices in the same
subnet.
D. Check the IP address settings of VioStor and your computer. Make sure
they are on the same subnet.
2. A channel on the monitoring page cannot be displayed.
Please check the following:
A. The IP address, the name, and the password entered on the camera
configuration page are correct. You can use the “Test” function to verify
the connection.
B. When the PC and the IP camera are on the same subnet, while VioStor is
on another subnet, you will be unable to view the monitoring screen from
the PC. You can solve the problems by the following methods.
Method 1: Enter the IP address of the IP camera as the WAN IP in VioStor.
Method 2: Configure the router to allow internal access to the public IP
address and the mapped ports of the IP cameras.
3. The recording is not working properly.
A. Make sure each hard disk tray is correctly locked on VioStor.
B. When only one hard disk drive is installed, make sure the HDD is installed
in the tray of HDD 1. The HDD 1 should be installed on top of the HDD 2.
C. Check if the recording function is enabled on the Camera Configuration
page (the function is enabled by default). Make sure the IP address, the
login name, and the password of the IP camera are correct.
D. If the above items are verified to work properly while the status LED
flashes green, the HDD may be damaged or cannot be detected. In this
case, turn off VioStor and install a new hard disk. If the problem persists,
please contact the technical support.
