YML826 Rev1 - Pan/Tilt Internet Camera
Q: Why does the Pan/Tilt Internet Camera work locally but not externally?
A1: Might be caused from the firewall protection. Need to check the Internet firewall with your
system administrator.
A2: The default router setting might be a possible reason. Need to double check if the configuration
of the default router settings is required.
Q: Why does a series of broad vertical white line appears through out the image?
A: A likely issue is that the CMOS sensor becomes overloaded when the light source is too bright
such as direct exposure to sunlight or halogen light. You need to reposition the Pan/Tilt Internet
Camera into a more shaded area immediately as this will damage the CMOS sensor.
Q: There is bad focus on the Pan/Tilt Internet Camera, what should be done?
A1: The focus might not be correctly adjusted for the line of sight. You need to adjust the Pan/Tilt
Internet Camera focus manually as described in Adjust Pan/Tilt Internet Camera Focus.
A2: There is no adaptor fitted with your C-type lens. If you have previously changed the supplied
CS-type lens, you may have unintentionally installed a C-type lens without fitting the adaptor first.
Q: Noisy images occur how can I solve the problem?
A1: The video images might be noisy if the Pan/Tilt Internet Camera is used is a very low light
environment. To solve this issue you need more lighting.
A2: There might be wireless transmission interference make sure there are no other wireless devices
on the network that will affect the wireless transmission.
Q: There is poor image quality, how can I improve the image?
A1: A probable cause might be the incorrect display properties configuration for your desktop. You
need to open the Display Properties on your desktop and configure your display to show at least
65’000 colors for example at least 16-bit.
NOTE: Applying only 16 or 256 colors on your computer will produce
dithering artifacts in the image.
A2: The configuration on the Pan/Tilt Internet Camera image display is incorrect. Through the Web
Configuration Image section you need to adjust the image related parameter for improve images
such as brightness, contrast, hue and light frequency. Please refer to the Web Configuration section
for detail information.
Q: There are no images available through the web browser?
A: The ActiveX might be disabled. If you are viewing the images from Internet Explorer make sure
ActiveX has been enabled in the Internet Options menu. Alternatively, you can use the Java Applet
for viewing the required images.
