Mike loved his job. It gave him pride knowing he never slacked off. Most cops or security people tend to get bored watching the camera's, and would sometimes fall asleep, but Mike never did. He was always vigilant and alert. 
 
 He mostly worked alone in his control room. The light from the monitors sometimes gave him piercing headaches, but Mike always pushed through. No one else could do his job as good as he could. He needed to watch and report any potential crimes in his daily report to command. It did n't pay well but it was Mikes passion. 
 
 It was another normal day, Mike alone with the monitors, each monitor showing 8 camera feeds. From time to time a single camera would go blank and be replaced by another. Mike had been doing his job for such a long time that he picked up on peoples routines. For instance Mike knew that the same man would stop at the road crossing on Camera 82 each weekday between 15:05 and 15:10 to give the beggar some change. 
 
 13:07. Camera 57 caught his attention. The fog made the image blurry but he knew it would clear up in a few minutes like it always did. 14:27. His attention shifted to Camera 21, it was a suburban street, the camera pointed towards the house across the road. A car pulled into the driveway, dropping off a girl of about 7 years old. The driver waved and blew a kiss before backing up and out of the driveway. The girl would always pick a few flowers from the garden before starting towards the front door. He shook his head thinking how unsafe this was. 
 
 It continued like this for the rest of the day until his shift ended and he had to type his incident report:

 He hit send feeling satisfied. If he keeps this up he might get a bonus soon.
