4. Setup Guide
4.1. Power over Ethernet (PoE) Connection
The Hiseeu system utilizes PoE technology, allowing a single Ethernet cable to transmit both power and video data to each camera. This simplifies installation and reduces cable clutter.
- Connect the NVR to a power source using the provided power adapter.
- Connect each camera to an available PoE port on the NVR using the provided Ethernet cables. The cameras will power on automatically.
- Connect the NVR to a monitor (TV or PC) via HDMI or VGA cable to view the live feed and configure settings.
- Connect the NVR to your router using the 3ft Ethernet cable for internet access, enabling remote viewing and app functionality.

7. Troubleshooting
If you encounter issues with your Hiseeu security system, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on monitor | NVR not powered on, monitor cable loose, incorrect input selected on monitor. | Ensure NVR is powered. Check HDMI/VGA cable connection. Select correct input source on monitor. |
| Camera offline/No video feed | Ethernet cable disconnected/damaged, camera not receiving power, NVR port issue. | Check Ethernet cable connection at both camera and NVR. Try a different NVR PoE port or cable. Reboot the NVR. |
| Remote access not working | NVR not connected to internet, incorrect network settings, app configuration issue. | Ensure NVR is connected to router and has internet access. Verify network settings in NVR. Reconfigure camera in mobile app. |
| False alarms from motion detection | Sensitivity too high, environmental factors (e.g., moving branches, shadows). | Adjust motion detection sensitivity in NVR settings. Define specific detection zones to exclude irrelevant areas. Utilize AI human/vehicle detection. |
| No recording | Hard drive full, recording schedule not set, hard drive fault. | Check hard drive status and capacity. Ensure recording schedule is active. If HDD is faulty, it may need replacement. |
