Hello, my name is Carlos Milanezi, I live in Brazil and I am an electrical engineer. I currently work with the design and execution of photovoltaic plants.
In one of our projects, we are implementing the plant's perimeter CCTV system using cameras from the manufacturer Dahua, model DH-IPC-HFW5241E-Z12E, together with an NVR 5216-EI. As design assumptions, we are working with distances between posts of approximately 80 to 90 meters. By carrying out tests during the day, we were able to achieve success with detecting people through intrusion lines. However, when carrying out night tests, we were unable to reach such distances.
Attached I am providing some photos of how the configuration is being carried out. We are working with the camera zoom at approximately 60%.
Could anyone help me with the settings?
