This system features Swann's True Detect PIR Thermal Sensing technology to reliably detect heat-generating moving objects, such as people, large pets and cars. With more accurate motion detection you have more reliable notifications and recording, eliminating false triggers such as falling leaves, bugs, rain and more, saving you hard drive space and playback time. With 5MP resolution, which is 2.4x better than 1080p Full HD, you can zoom in closer with incredible clarity to license plates, facial features and clothing patterns. This surveillance system comes with a massive 2TB hard drive and 4 weatherproof PRO-5MPMSB security cameras built tough for the outdoors or indoors. See in the dark up to 100' (30m) with the camera's powerful infrared night vision. The cameras come with BNC cables. If your property has existing BNC cables, we advise you to test your new system for 2 days with the existing cables before full installation. For optimum performance, we recommend you use the new cables supplied. Expand your kit by adding up to 4 more cameras for a complete 8 channel surveillance system, suitable for medium-sized businesses and detached homes for monitoring indoors and outdoors. You may also consider the more discreetly shaped dome camera PRO-5MPMSD that blends into more easily into its surroundings. The Home Safe Views app ensures you'll always be connected to your home or business, allowing you to see the cameras on your phone or tablet. You can even search the recordings to play them back, wherever you are in the world.
