Dynamic Ip Connection - HIKVISION DS-2DB4236I-CWX User Manual

2.2.2 Dynamic IP Connection

Before you start:
Apply a dynamic IP from an ISP. With the dynamic IP address, you can connect the network
camera to a modem or a router.

Connecting the network camera via a router
Steps:
1. Connect the network camera to the router.
2. In the camera, assign a LAN IP address, the subnet mask and the gateway. Refer to Section
2.1.2 for detailed LAN configuration.
3. In the router, set the PPPoE user name, password and confirm the password.

For your privacy and to better protect your system against security risks, we strongly
recommend the use of strong passwords for all functions and network devices. The
password should be something of your own choosing (using a minimum of 8 characters,
including upper case letters, lower case letters, numbers and special characters) in order
to increase the security of your product.

Proper configuration of all passwords and other security settings is the responsibility of
the installer and/or end-user.
4. Set port mapping. e.g. 80, 8000 and 554 ports. The steps for port mapping vary depending on
different routers. Call the router manufacturer for assistance with port mapping.
5. Apply a domain name from a domain name provider.
6. Configure the DDNS settings in the setting interface of the router.
7. Visit the camera via the applied domain name.
 Connecting the network camera via a modem
Purpose:
This camera supports the PPPoE auto dial-up function. The camera gets a public IP address by
ADSL dial-up after the camera is connected to a modem. You need to configure the PPPoE
parameters of the network camera. Refer to Section 6.1.1 Configuring PPPoE Settings for
detailed configuration.
Note:
The obtained IP address is dynamically assigned via PPPoE, so the IP address always changes after
rebooting the camera. To solve the inconvenience of the dynamic IP, you need to get a domain
name from the DDNS provider (e.g. DynDns.com). Follow the steps below for normal domain
name resolution and private domain name resolution to solve the problem.

Normal Domain Name Resolution
Steps:
1. Apply a domain name from a domain name provider.
2. Configure the DDNS settings in the DDNS Settings interface of the network camera. Refer to
Section 6.1.1 Configuring DDNS Settings for detailed configuration.
