Most DIY security systems in our tests sell security cameras that record video if it detects motion, which can be used to help with police reports or insurance claims. Although most home security systems include alarms or sirens in their hubs, you can buy separate sirens to place closer to entry points for maximum effect, which can deter intruders and alert your family of a break in. If you buy smart plugs and smart lights for your home security systems, they can work together to deter intruders – when your system detects an intruder, it can turn your home's lights on.

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.Posted by Anonymous at 3:19PM | (2 comments)
