We're ready to help you build a complete system for commercial, office/business, and large properties. We've packed together 16NHD-820 2 Megapixel bullet cameras from the Swann Range that are perfect in the 16 channel NVR bundle. They are able to generate super clear 2.1 Megapixels (1920 x 1080 pixels) video images along with latest infrared cut filter for amazing night vision to 115ft / 35m. They are built to suit any conditions with weather resistant rating of IP66 for indoor and outdoor use. The Swann 16 channel 1080p video recorder gives 1080p high definition live viewing & playback in real-time. Set & forget by recording continuously from 16 Channels for 45 days+ onto a 3TB hard drive (expandable to 32TB) or even longer with motion detection.
