For instance, cameras may freeze in sub-zero temperatures, as indicated by research from Smith and Lee (2021), which found that consistent temperatures between 0°C and 40°C maintain optimal functioning.

Humidity: High humidity levels can lead to condensation inside the camera housing. This moisture can obstruct the lens or cause internal fogging. Studies show that outdoor cameras in humid climates may require additional protective features to prevent malfunction (Brown, 2020).

Physical obstructions: Objects such as trees or buildings can hinder camera angles and reduce visibility. Proper planning in camera placement can overcome these barriers. A survey conducted by Wilson (2023) found that strategic positioning increased the effectiveness of surveillance by up to 30%.

By understanding how these environmental factors affect CCTV camera performance, users can better select and position their surveillance systems for optimal results.
