PING Your IP Address
The PING (Packet Internet Groper) command can determine whether a
specific IP address is accessible by sending a packet to the specific address
and waiting for a reply.
It can also provide a very useful tool to confirm if the
IP address conflicts with DCS-1000 over the network.
Follow the step-by-step procedure below to utilize the PING command but
first you must disconnect DCS-1000 from the network.
Start a DOS window.
Type ping x.x.x.x, where x.x.x.x is the IP address of the DCS-1000.
The succeeding replies as illustrated below will provide useful explanation to
the cause of the problem with DCS-1000 IP address.

Trouble Shooting
Q:
I cannot access DCS-1000 from a web browser?
A1:
The possible cause might be the IP Address for the DCS-1000 is already
being used by another device.
To correct the possible problem, you need to
first disconnect DCS-1000 from the network.
Then run the PING utility
(follow the instructions in Appendix B - PING Your IP Address).
A2:
Another possible reason is the IP Address is located on a different subnet.
To fix the problem, run the PING utility (follow the instructions in Appendix
B - PING Your IP Address).
If the utility returns “no response” or similar, the
finding is probably correct, then you should proceed as follows:-
In Windows 95/98/2000 and Windows NT, double check the IP Address of the
DCS-1000 is within the same subnet as your workstation.
Click “Start”, “Setting”, “Control Panel”, and the “Network” icon.
Select TCP/IP from the “Network” dialog box and from the “TCP/IP
Properties” dialog box click on “Specify an IP address”.
If the DCS-1000 is situated on a different subnet than your workstation, you
will not be able to set the IP address from this workstation.
To verify make
sure the first 3 sections of the IP address of the DCS-1000 corresponds to the
first 3 sections of the workstation.
Therefore the IP address of the DCS-1000
must be set from a workstation on the same subnet.
A3:
Other possible problems might be due to the network cable.
Try
replacing your network cable.
Test the network interface of the product by
connecting a local computer to the unit, utilizing a standard Crossover (hub to
hub) Cable.
If the problem is not solved the DCS-1000 might be faulty.
Q:
Why does the Power LED not light up constantly?
A:
The power supply used might be at fault.
Confirm that you are using the
provided power supply DC 5V for the DCS-1000 and verify that the power
supply is well connected.
Q:
Why does the LAN LED not light up properly?
A1:
There might be a problem with the network cable.
To confirm that the
cables are working, PING the address of a know device on the network.
If the
Page 68 / 83

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 immediately 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.

Note:
Applying only 16 or 256 colors on your computer will produce dithering
artifacts in the image.
A2:
The configuration on the DCS-1000 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.

I/O Connector
I/O Connector Definition for DCS-1000
An 8-pole connector is provided for auxiliary IO connections to the DCS-1000.
The IO connector provides the physical interface for 2 digital output and 2
digital input that is used for connecting a diversity of external alarm devices to
the DCS-1000 such as IR-Sensor and alarm relay.
The digital input is used for connecting external alarm devices and once
triggered images will be taken and e-mailed.
The supported transistor output can give a maximum of DC 5V to the
externally connected alarm devices and once triggered the current will activate
the devices.
