4.1 Live Viewing
Once powered on, the 15.6-inch monitor will display live feeds from all connected cameras. You can switch between single-camera view and multi-camera grid view using the NVR controls.
4.2 Two-Way Audio
Each camera is equipped with a microphone and speaker, enabling two-way communication. Through the mobile app, you can speak into your phone, and your voice will be transmitted through the camera's speaker. Similarly, the camera's microphone records audio from the surveillance area.

4.3 Recording Modes
The NVR supports various recording modes:
- Continuous Recording: Records 24/7, overwriting the oldest footage when the 2TB HDD is full.
- Scheduled Recording: Set specific times for recording.
- Motion Detection Recording: Records only when motion is detected, saving storage space.

4.4 Night Vision
The cameras feature advanced night vision with infrared and LED lamps. In low-light conditions, the system typically records in black and white. However, upon detecting a person or moving object, it can switch to color night vision to capture clearer details of potential intruders.
