Cemetery watchman sets up hidden camera and falls asleep

Lately, Sergey’s life has been plagued by a relentless streak of bad luck. He was forced to quit his job. At the large supermarket where he worked as a security guard, a series of thefts occurred during his shift.
The thieves managed to stealthily remove goods from the store shelves in broad daylight. Sergey had left his post to make a very important call for just a couple of minutes, but the manager wouldn’t listen to his excuses and immediately showed him the door. His personal life was also hopelessly bleak.
Not long ago, his girlfriend Nastya left him. She left for a banal reason, common among modern women. “You absolutely can’t make money, you loser,” Nastya scolded him.
“I don’t want to drag out a miserable existence with you.” Sergey’s heart was heavy, he was so tired of people and their betrayals that he decided to simplify his life and take a job as a cemetery security guard. Here, at least, interaction with people was kept to a minimum.
And that was exactly what he needed right now. But there was a problem. The guard position was only for the night shift, and Sergey had a small side job on the computer, so he wanted to sleep at night to work productively during the day.
Sergey decided to be a bit cunning. “No need to personally monitor the cemetery minute by minute, after all, the dead won’t crawl out of their graves and run away.” He could, like at the supermarket, rely on video surveillance.
The man checked: the camera was working perfectly. He attached a sensor to the camera, linked to his phone. If the sensor detected unusual movement, the phone would immediately alert him.
“Well, seems like I’ve covered everything, now I can sleep peacefully,” Sergey thought, settled comfortably on the couch, and closed his eyes. But his sleep didn’t last long…
