When you start looking for a camera system, you will see two types over and over again. There are systems based on the Internet Protocol (IP) How the Internet Works How the Internet Works We can now access the Internet from our home computers, office computers, laptops, and our phones. But many people are still not completely sure what the Internet is and how it really works. Read More What is the difference? What are the pros and cons of these two systems? Even more important, which system is the most secure? Let's see.

What is the difference between IP security cameras and DVR systems?

There are two main differences; what kind of cameras they use and how the cameras and the recorder communicate with each other, or their networking method. Let's look at the two networking methods first.

An IP-based network requires each device to have its own IP address. An IP address is a bit like a phone number. You call a phone number, you get your friend Jim. That specific phone number will always connect you to Jim. A specific IP address will always connect you to the device that has that IP address.

If you have two cameras, camera one could have an IP address like 192.168.2.10 and camera two could be 192.168.2.11. There is usually also a computer in your security system, known as a network video recorder (NVR). It will have its own IP address. Let's say it's 192.168.2.1.

What is the difference between digital and analog cameras?

Surprisingly little.
