IP systems are able to utilize Megapixel Resolution which offers a clearer picture than Analog systems. IP Security Cameras are substantially more expensive than analog and require at least some knowledge of IP Networks to properly install and maintain. Video quality is usually better than that of analog cameras, but it depends on the Megapixel rating of the cameras in question. Live viewing IP Cameras with less than 2 Megapixels will
deliver footage at a resolution of 720P while IP Cameras with 2 Megapixels or more will deliver footage at a resolution of 1080P for live viewing. As with the analog systems, the playback of recorded video
is limited by the NVR. Generally speaking, we don’t recommend IP Cameras for a DIY home security camera installations because of the up front installation time and complexity. If you are looking for the best video quality possible for both live and recorded surveillance footage, the only option is an HD SDI System consisting of both HD SDI Cameras and HD SDI DVR. This system will provide real time 1080P Video exactly like watching TV in high definition and does not require any special knowledge of networks to install and maintain. HD Security Cameras can provide up to six times higher resolution than standard video cameras, giving you much clearer video quality on your home camera system. HD SDI Systems are the state of the art and while the cost is more than the basic analog systems it is substantially less than a comparable IP System. The only downside is that, because of the much higher resolution these security cameras record at, they require about 3 times as much hard drive storage capacity as standard analog systems.
