Additional Details ------------------------------ Product description: With our latest 16-channel Fusion Series NVR and twelve 4K Smart Deterrence cameras, this security camera system will provide you with high quality recordings and the smartest features to protect your property. Features such as Smart Motion Detection Plus, Active Deterrence LED lights and siren, and two-way talk audio are designed to stop potential events before they happen. The NVR also includes a large 3TB hard drive for private local recording with no monthly fees and is easily connected to our Lorex Home App for easy remote viewing and motion notifications. As part of the Lorex Fusion collection, the NVR can accommodate up to two Wi-Fi products on open channels, such as Wi-Fi cameras, doorbells, or floodlights. This camera comes with plenty of features that will help ward off uninvited guests. First, there is a motion-activated warning light that can be customized to only be triggered when a person or vehicle is detected. Second, there is a remote-triggered siren that you can control from your Lorex Home app. When the camera sensors detect motion, the system will send a notification directly to your phone, allowing you to remotely access the camera and set off a warning alert. A built-in speaker and microphone allows for crystal-clear audio functionality. Listen-in audio recording will add a whole new dimension to your overall security monitoring, as it can provide additional details (like a voice) should an incident occur. This camera also has a speaker that allows you to communicate with others through the camera using the Lorex Home app
