For remote viewing and control, download the free XMeye Pro App from your smartphone's app store (iOS or Android). Scan the QR code displayed on the NVR's monitor to easily add your device to the app.
4. Operating Instructions
4.1 Live View and Playback
Access live camera feeds and review recorded footage through the NVR's connected monitor or via the XMeye Pro app. The NVR supports 24/7 recording to the 2TB HDD.

This image shows a user holding a smartphone with the XMeye Pro application open, displaying multiple live and recorded video feeds from the security cameras. This highlights the system's remote viewing and personalized control features, allowing users to monitor their property anytime, anywhere.
4.2 Motion Detection and Smart Alerts
The system features advanced motion detection with Person/Vehicle Detection capabilities. This reduces false alarms and provides more accurate alerts.
- Configuration: On the NVR or via the XMeye Pro app, navigate to the 'Alarm' or 'Detection' settings.
- Enable Detection: Activate motion detection and select 'Person Detection' and/or 'Vehicle Detection' as needed.
- Set Detection Area: Define specific areas within the camera's view where you want motion detection to be active.
- Alerts: Configure how you receive alerts (e.g., push notifications to your phone, email alerts).

This image illustrates the advanced AI detection capabilities of the DIHOOM security camera. It shows a camera with an active spotlight and a siren icon, indicating its ability to deter intruders. The diagram also depicts how alerts are sent to a smartphone, tablet, and laptop, and how the system can notify authorities.
4.3 Night Vision and Dual Deterrence
The cameras offer powerful night vision and dual deterrence features:
- Infrared (IR) Night Vision: Provides crisp 4K black & white video up to 100 feet in dark conditions.
- Color Night Vision: The built-in LED spotlights can activate upon motion detection, illuminating the area to record colorful footage at night.
- Siren: An optional motion-activated siren can be configured to sound, providing an audible deterrent to unwanted visitors.
4.4 4K Ultra HD Resolution
The 8MP cameras deliver 4K Ultra HD resolution, ensuring highly detailed and clear images. This allows for easier recognition of faces, license plates, and other fine details when zooming in.

This image demonstrates the superior clarity of 4K Ultra HD resolution compared to 2K resolution. The top half shows a sharp, readable license plate captured in 4K, while the bottom half shows the same license plate appearing pixelated and less clear in 2K, emphasizing the enhanced detail provided by 4K.

This image illustrates the superior detail of 4K Ultra HD resolution. It shows a girl playing soccer, with a zoomed-in comparison of her face. The 4K view on the top right clearly shows finer details compared to the 1080P view on the bottom right, demonstrating less pixelation and greater clarity.
5. Maintenance
5.1 Camera Cleaning
Regularly clean the camera lenses with a soft, damp cloth to ensure clear image quality. Avoid abrasive cleaners that could scratch the lens.
