camera.

working. If you see a picture this means the problem is coming from the camera.

I cannot connect to the recorder via the internet?
1. The first thing to check is does your internet provider block any ports.
2.
Are you using the IP address from the Internet Service provider?
3. If you are using a router are the ports in your router opened?
( NOTE: Please be sure that HTTP port, Control port, Data port are open.
Please refer to “Network Setup Menu” section for port settings. For example,
HTTP port: 00080, Control port: 01600, Data port: 37260, the last digit +1
which is 37261, +2 which is 37262 and +3 which is 37263.)
4. If you are using Windows XP please update the Java Virtual Machine. This can
be done by going to http://java.sun.com and downloading the file called
JavaVM.

If you have a Dynamic IP address from your Internet Service Provider.
ƒ
Dynamic IP addresses can cause conflicts when trying to connect to DVR(s) on
a high speed internet connection. With new router technology (DDNS), it
allows you to overcome this problem. DDNS lets you assign a fixed host and
domain name to a dynamic Internet IP address. It is useful when you are hosting
your own DVR, website, FTP server, or other server behind the Router. Before
using this feature, you need to sign up for DDNS service at
www.dyndns.org or
www.tzo.com . (Preferred routers: Linksys BEFSR41 V3 or DLINK DI624 or any
router that offers DDNS.
