How often are camera sweeps conducted during daylight hours?

• A. Every 2 hours
• B. Every 4 hours
• C. Every 6 hours
• D. Every hour

Answer: (B)

The main idea is choosing a balance between keeping camera health and coverage reliable and not overburdening staff. During daylight hours, visibility is good, so operators can efficiently verify feeds, check that cameras are online, lenses are clean, and there’s no obstruction or tampering. A four-hour interval provides timely detection of issues—like a camera going offline, a power or network hiccup, or a new obstruction—without requiring constant checks across every site. Checking more often, such as every two hours or every hour, would increase workload without a proportional gain in security in daylight. Waiting longer than four hours, like six hours, risks missing problems for longer stretches. So, a four-hour cadence during daylight offers a practical balance between vigilance and efficiency.
