Digital security cameras
A- It sounds as though you are security conscience and have needs for quality images. Not long ago digital security cameras (CCTV) were much more expensive than traditional analog cameras. However, prices have come down significantly and digital cameras are very competitive. Additionally, in many situations digital cameras have a significant advantage.
Digital technology now allows us to user fewer cameras to cover more area in greater detail. Consider the picture to the {right}. The upper left image is an actual digital camera image. The other three images are all taken from the same digital image.
A conventional analog camera with the same camera angle could not produce the details of the other the other three pictures. Further it would take THREE analog cameras to produce the same images. With proper system design and camera placement, more can be accomplished with fewer cameras using digital equipment.
Therefore, it is very possible that installing a digital camera system may provide more detail, covering more area, for nearly the same cost as a traditional analog system.
