1. Product Overview
The xmartO WNS28 is an 8-channel WiFi Security NVR/DVR system featuring an integrated 12.1-inch 1080p Full HD screen. This system supports up to 8 xmartO WiFi security cameras, including 5MP, 3MP, 2MP (1080p), 1.3MP (960p), and 1MP (720p) resolutions. It is designed for convenient home surveillance with easy remote viewing capabilities and support for SATA HDDs.
The NVR incorporates dual WiFi modules: one dedicated for camera connections to maintain a clear home WiFi network, and another for connecting the system to the internet via WiFi, eliminating the need for a wired connection to your router. It also features G3 AUTO Dream Liner Wi-Fi relay technology, which automatically uses a closer camera as a WiFi repeater to extend the range to the NVR for cameras with weaker signals.
The system offers dual recording modes, capturing 24/7 footage and simultaneous motion events. During playback, events are highlighted for quick review. The companion mobile application provides a daily message list with snapshots and video clips of detected events.

4.2 Camera Pairing
The xmartO NVR system features AUTO-PAIR technology, meaning cameras should automatically connect to the NVR once powered on. If a camera does not connect automatically or if you are adding a new camera, follow these steps:
- Ensure Empty Channel: In the NVR's main menu, navigate to 'Device Manage'. Check for an empty channel. If all channels are occupied, you may need to delete an existing channel to free one up for the new camera.
- Access 'Add by WiFi': Right-click on the NVR screen to open the main menu. Select 'Add by WiFi'. The NVR will begin searching for available cameras.
- Power Camera: Plug the camera's power adapter into the camera and then into a power outlet. Wait approximately 10 seconds for the camera to initialize.
- Reset Camera (if needed): If the camera does not appear in the 'Add by WiFi' list after a minute, locate the reset button on the camera (refer to the camera's specific manual for location) and press and hold it for 10 seconds. Release the button and wait for the camera to restart and attempt to pair.
- Verify Connection: Once the camera is successfully paired, its live view will appear on the NVR screen.
