cabling is OK and your network is reachable, you should receive a reply
similar to the following (...bytes = 32 time = 2 ms).
A2: The network device utilized by the DCS-1000 is not functioning properly
such as hubs or switches. Confirm the power for the devices are well
connected and functioning.
Q: Why does the DCS-1000 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 DCS-1000 into a more shaded area immedia tely as this
will damage the CMOS sensor.
Q: There is bad focus on the DCS-1000, what should be done?
A1: The focus might not be correctly adjusted for the line of sight. You need
to adjust the DCS-1000 focus manually as described in Adjust 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 DCS-1000 is used is a very low
light environment. To solve this issue you need more lighting.
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.
