Why is lighting important for CCTV systems?

Lighting plays a critical role in the performance of CCTV systems as it significantly impacts the clarity and quality of the images captured. Proper lighting ensures that the camera can effectively capture detailed images, which is particularly crucial in low-light conditions. When there is insufficient light, the camera may struggle to produce a clear and discernible image, leading to blurred or grainy footage. This is especially important for surveillance purposes where identifying a person, object, or event is necessary for safety, security, and operational assessments.

Good lighting not only aids in capturing high-quality video but also enhances the overall effectiveness of surveillance systems, making it easier to analyze incidents and provide clear evidence when required. In contrast, the other options pertain to aspects that are less relevant to the core function of CCTV systems or address peripheral considerations rather than the fundamental nature of image capture.
