There are two kinds of IP cameras:
- Centralized IP cameras, which require a central Network Video Recorder (NVR) to handle the recording, video and alarm management.
- Decentralized IP cameras, do not require a central Network Video Recorder (NVR), as the cameras have recording functionality built-in and can thus record directly to digital storage media, such asflash drives, hard disk drives or network attached storage.
The diagram explains how a IP (Internet Protocol) Network camera can be used in your Network. It is suitable for both Wired and Wireless(802.11G built in) Networks. If you have an existing network the system is simply plug and play.
The IP Camera can be connected directly to the Internet without using a computer. So when the power goes off and comes on your camera will automatically come online. No need to restart the Computer or the DVR manually.
Comparison between IP camera and Analog DVR (via analog camera)
DVR | IP Cameras |
1.End to interlace problems | |
· Interlaced scan · Each image formed from two interlace fields · Blurriness from capturing moving objects, even when connected to a DVR | · Progressive Scan · Entire image captured at one time · Crystal clear images even with a high degree of motion in the scene |
2.Megapixel resolution | |

6.Flexible cost effective infrastructure | |
| · IP = established, standardized, interoperable · Digital images = no quality reduction · Many streams transmitted over the same line · A single network wire = hundreds of simultaneous full frame rate video streams |
