This is something I had been wondering about because if the fishery official was floating in the water for six hours before being shot by the North Koreans, why didn’t anyone try to rescue him?:

South Korea’s defense ministry said Wednesday there were no such words as “shoot to kill or fire” in the military’s initial intelligence on North Korea’s killing of a South Korean fisheries official in the West Sea.
The ministry also expressed regret over some reports that said the South’s military took no action despite hearing the North’s order to kill the official.
“What happened during the incident in which (the North) shot (the South Korean fisheries official) and burned (his body) was determined after a considerable lapse of time by analyzing pieces of intelligence,” the ministry said.
It also said the military did not know all of the facts of the incident in real time.
In line with the ministry’s remarks, the South Korean presidential office Cheong Wa Dae denied the reports that the government had full awareness of the situation but did not suitably respond to it.

You can read more at the link, but this leads me to believe that the ROK military must have cameras and listening devices placed in certain areas or unmanned aerial reconnaissance that they can download as needed to view imagery from in that area.
