What is a major advantage of using a digital camera in photo surveillance?

The major advantage of using a digital camera in photo surveillance is that it allows for immediate viewing of images. This capability is crucial in surveillance contexts, where the timely assessment of an image can significantly impact the effectiveness of the operation. Being able to review images on-site means that investigators can quickly determine whether further action is needed based on what is captured in real-time. It also enables better decision-making regarding the next steps in an investigation, as immediate feedback can guide the handling of a situation.

Immediate viewing also allows for adjustments to be made during a surveillance operation, such as changing angles or repositioning the camera to improve image quality. This responsiveness contributes to the overall efficiency of photo surveillance compared to traditional film cameras, where the development of images could cause delays in analysis and response.
