IP Cameras

Introduction to Network / IP Cameras

What is an IP Camera?

‘IP’ stands for Internet Protocol, which is a protocol for transmitting data across a network. An IP Camera or Network Camera is a camera that plugs directly into your network router, and is not reliant on a computer to work. Data from the IP camera is transmitted through the network, and can be securely viewed at a remote location.

What is the advantage of an IP Camera over a USB Web Camera?

An IP Camera does not depend on a computer, and does not require a specific application to run and transmit images. A USB Camera is dependent on a computer, and requires the computer to be powered on and logged in.

Why choose an IP Camera over a standard camera?

An IP Camera allows you to view images on your local computer and from remote locations without needing a dedicated Observation System or DVR. These cameras are easy to install and configure, and can be located anywhere that a network cable can be run.

Is my IP Camera Secure?

The images are encrypted and control access is granted by inputting a User Name and Password. This helps to prevent unauthorized people from gaining access to your camera.

Do I need a Static IP Address?

A static IP address is not needed to connect to the camera. DCS-Secuirty offers a free DDNS service, which provides you with a URL (web address) that always points to the most current IP address at the location of the camera. Other DDNS services can be used.

A static IP address is useful to prevent interruption to the connection with your camera (as the DDNS Service syncs to the new IP), however it is very common for Internet Providers to lease your IP address for a set amount of time, and then to release you a new IP address.

What is DDNS?

DDNS is Dynamic Domain Name Service. A DNS (Domain Name Service) translates domain names (i.e. www.dcs-security.com) into a static IP Address ( A DDNS (Dynamic Domain Name Service) will translate a domain name into a non-static IP address (an IP address that is not fixed, and can change often).

How do I know if I have a Static or Dynamic IP Address?

Check with your Internet Provider - they will be able to tell you if your IP address is Static or Dynamic. Most residential Internet service plans use dynamic IP addresses.
