When the camera's compression format is set to M-JPEG and when saving
from the recorder's setup menu or measuring from the program settings
repeatedly, a few minutes of live image are not recorded and instead a black
screen appears. If this happens, wait about 10 minutes.

Image is not displayed because ActiveX control is not installed correctly
if logged in to a user's account with limited access privileges. Log in to a

ActiveX control cannot be installed sometimes when you log in the
network with domain authentication (Active Directory). Register trusted
sites and add the security setting.
1. Start up Internet Explorer and click on "Tools".
2. Click "Internet options".
3. Click the "Security" tab, and select "Trusted sites".
4. Set "Low" for "This zone's security level" (lowering the security level
lowers the security level of the PC being used).
5. Click "Site". Do "Add" to URL of the recorder. When you do this,
check that the "Must check all servers (https:) of sites in this zone"
check box is not selected.
