If you are considering a new system or upgrading an existing system, then you have to decide between an IP or analog video format.

What is an analog video security system?
Analog CCTV systems send video in a traditional base band format typically over coax cabling back to a digital video recorder (DVR). The video signal is then digitised and stored on the DVR 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. 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.

What is an IP video security system?
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 a Hybrid video security system?
Hybrid CCTV systems combine IP and analog video, and can be a great way to transition an analog system to IP without needing to replace all of the existing cameras.

Why Choose an Analog System?
There is only one reason why anyone would choose analog over IP, Cost. IP video security systems are 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. More detail on the cost differences later.

Why Choose an IP System?
Resolution. One of the main factors driving interest in IP video systems is the high resolution that they can offer. Analog cameras max out on resolution at about 580 TVL which equates to roughly 0.4 mega pixels. High end IP cameras on the other hand, are currently available at resolutions above 8 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.

Summary
IP Video will almost always be more expensive, but the availability of much higher resolution recorded images makes it a much more powerful system. The ability to digitally zoom in on recorded video makes identification much more likely.
