An IP camera is also known as a network security camera because it is typically deployed in a network environment. This type of surveillance system differs from analog closed circuit systems, in that it can send and receive data via a computer network and the Internet.
What is a Data Network?
In surveillance, a data network is a system that has its own IP address. It is worth noting that a network security camera system doesn’t necessarily mean it is on the Internet, these systems can also be used on a private LAN network.
An IP network requires each device to have its own unique IP address – similar to a phone number. This number connects you to its associated device and will also typically be connected to an NVR with its own IP address.
The computer identifies and communicates with the cameras through their IP addresses, and the cameras will then reply. Because the computer knows which IP address is associated with each camera, it knows where the images have come from and is therefore able to organise them correctly.
The Benefits of an IP Network
There are distinct benefits of using network security cameras over analog technology, these include:
- Users are granted remote administration from any location (unless using a LAN network). You can login to this secure server remotely and it will grant you access to a web-based interface to view and review real-time footage. The user is also able to access this through their mobile device as well.
- The ability to view and send images to any place or anyone with an Internet connection. This means you don’t have to be present on-site or even in the country to observe the surveillance at your home or business.
- Better quality images due to progressive scanning. A typical analog camera offers around 0.4 MP (megapixel), a standard IP camera offers 2 MP, which is a significant improvement over analog. Not only does this significantly improve the quality of the image but also many IP cameras offer up to 10 MP. The benefit of this is not only in image quality, but it can also reduce the number of cameras required.
