How to use

Mount the camera at the desired location with a clear view of the monitored area, ensuring the chosen position matches the wide-angle coverage of the 2.8mm lens. Connect the device to power and your local network using the appropriate power-over-Ethernet (PoE) or external power source supported by your system. Configure network settings and enable motion detection and analytics through the camera’s web interface or your network video recorder software. Adjust image settings such as exposure, gain, and privacy masks as needed to optimize video quality for the specific environment.

Recommendations

Install the camera at a height that balances wide coverage and facial recognition needs (typically 2.5–4 meters). For best low-light results, avoid direct bright light sources facing the lens and use complementary lighting if required. Regularly check firmware updates and maintain a secure network configuration to ensure reliable operation and protection against unauthorized access.
