Experience the 4K difference - With 4K resolution, nothing is left to the imagination. The higher number of pixels (3840 × 2160 as opposed to 1920 × 1080) gives your video footage superior detail and definition, and clearly outlines the distinct features of objects that appear on camera while maintaining realistic color representation. Having more than 8 million pixels also prevents the distortion or blurring of the image when using the digital zoom. | Smart Motion Detection Plus - This NVR supports cameras that feature smart person, vehicle, and face detection. Thanks to this innovative feature, a motion event and notification will only be created whenever a person or vehicle is detected. This effectively reduces the number of unwanted false alerts. | Expand your system with the Fusion Collection - The Lorex Fusion Collection is a set of Network Video Records (NVRs) and Wi-Fi devices that are united by our Lorex Home App. Working together, the NVR can essentially "fuse" together Wired and Wi-Fi systems! | Panic button Stop events before they happen. An easy-to-use panic button located on the front of the recorder will activate all lights and sirens on your compatible Active Deterrence cameras to deter potential intruders. | Reliable security grade hard drive with no hidden storage fees - Included in the NVR is a built-in security-grade hard drive that has been designed to meet the demands of 24/7 surveillance recording. With the possibility of increasing storage space up to 8TB, there is more than enough room to safely store all motion events that only you can access.
