The answer depends on the type of camera, the lighting conditions, and the level of magnification. Daytime CCTV cameras typically have a range of 10-70ft, although some night-vision cameras can see up to 100-200ft. The key factor is the amount of light available - in low light conditions, even the best camera can only see a few feet. To get the most out of your security cameras, it's essential to understand their limitations and how to work within them. With the proper positioning and lighting, you can make sure your cameras are covering the areas you need them to.
