Example answer: "One time two monitors started blinking on and off, and then suddenly shut off. I quickly noted down the time that this happened and I called my supervisor. Since she was on the other side of the building, it would take her at least a couple of minutes to get here. I took that time to examine the cables to see if there was any damage. I also checked the electrical outlets and radioed other staff to see if they were having the same issue. I kept an eye on other nearby cameras that weren't affected by the issue to see if there were any people entering or exiting the blacked out area."
