ZOSI 16-Channel 4K Home Security System — 16CH NVR (4TB HDD) with AI Human Detection, 12× 4K Wired Outdoor PoE IP Cameras

Overview: This ZOSI bundle includes a 4K 16CH NVR with a preinstalled 4TB HDD and twelve 4K wired outdoor PoE IP cameras to provide continuous 24/7 coverage for your property. The system supports up to 16 cameras recording at once for full home or business surveillance. Camera construction & image: Each camera delivers Super HD 4K/8MP video and is built with an IP66 metal aluminum housing for reliable indoor and outdoor performance. A 103° ultra-wide field of view lets each camera cover more area, while IR LEDs enable clear night vision up to 100ft. Audio & deterrence features: Cameras can capture and record audio to provide additional evidence. Two-way audio lets you listen and speak through the camera, and integrated spotlight & siren functions give you active deterrent options. Smart detection & alerts: Built-in AI Human Detection filters out irrelevant motion and sends App push notifications and an email whenever a person is identified. You can define custom detection zones to focus alerts on the areas that matter most. Storage efficiency: H.265+ coding reduces video file sizes without sacrificing image quality, conserving hard drive space so you can store recordings longer and enjoy smoother playback. Remote access: View live streams, replay footage, and adjust system settings remotely from mobile devices using the ZOSI Smart App or AVSS Client. Expandability: Q1: Can I add more cameras to this system? Yes. This is a 16Channel 8MP PoE NVR. You can add more (only ZOSI) 8MP, 5MP or 2MP POE Bullet or dome cameras. But the total number of cameras connected to the NVR should not exceed 16. 4K output instructions: Q2: How to get the 4K 8.0MP resolution: (1) Please make sure that your TV monitor is 4K or better than 4K resolution, and connect the NVR to your TV monitor. (2) Setup the system, and go to Main Menu- Set up-Basic to change the "Video Output" to "3840 * 2160" manually. Noted: The default setting of the DVR is 1024 x 768. If the monitor resolution is lower than 4K then the system will not show the 4K resolution.
