Swann NVR8-7085

Best for Whole-Home Security

With this eight-camera system, your home will be on total security lockdown. Initial installation takes a while (just one camera took 20 minutes to set up), but it's worth it. Each cam is weather-resistant and shoots in smooth HD and up to 82 feet in clear infrared at night. You can view all feeds remotely from your phone or even on your living room TV. [$1,200; swann.com]
