What is an IP Network Solution
IP video cameras broadcast their video as a digital stream over an IP network. Like an analog system, video is recorded on hard drives, but since the video is an IP stream straight from the camera, there is more flexibility as to how and where that video is recorded. The DVR is replaced with an NVR (network video recorder), which in some cases is just software since it doesn't need to convert analog to digital. Video footage can then be stored on new or existing network RAID drives as directed by the NVR software.
What is an analog video security system?
Cameras on an modern analog CCTV system send their video in the traditional base band format over coax or UTP cabling back to a digital video recorder (DVR). Here, video is digitized and stored on hard drives. Most modern DVRs are a network device, and as such can be accessed remotely from the LAN, or with the proper configuration, from across a WAN or the internet. There are no tapes to change. Video is kept on hard drives, typically on a FIFO basis so there is always a rolling video archive of the past X days. So, despite the fact that video is being transmitted from the cameras in an analog format, live and recorded video is still available over the network.
Why Choose an IP System?
Resolution
One of the biggest factors driving interest in IP video systems is the high resolution that they can offer. Analog cameras max out on resolution at about 3 mega pixels. High end IP cameras on the other hand, are currently available at resolutions above 5 mega pixels. This high resolution in turn gives users the ability to zoom in on video after the fact, and still have usable video.
Another benefit to IP video is that it is much more compatible with wireless. Wireless analog systems are available, but they either have to convert to IP anyway and broadcast over the 802.11 IP network (which adds cost for encoders), or they get crammed onto the over saturated regulated frequencies and often encounter interference.
Why Choose an Analog System?
Cost.
IP video security systems are generally more expensive, and sometimes a LOT more expensive. But, because the systems are designed differently from the ground up, there are situations where the cost difference between analog and IP is minimal, and even scenarios where IP video is cheaper.
