PALS is a security system of robots that resemble TVs with faces that hang off of walls. As they look innocent at first, they will surely creep people out once they spot any intruders.
AppearanceA PALS robot seems to have an arm-like part of them that keeps the TV attached to the wall while letting them
move around. The face on the screen of the TV is a little friendly smile and attached to the bottom of the TV is a laser.
PALS was one of the original security systems that protected facilities. They were created a while back but are still able to keep up today. They were also originally designed to look friendly at first to trick troublemakers until it's face turns into a face of a maniac. It definitely did help a lot.
The TV will just wait there until somebody goes into the lighted area. There will be 4 phases, the face becoming more scarier until it finally alerts the building that somebody has intruded the area. There was also an original concept that would either tranquilize or kill the intruder but was scrapped due to it being lethal.
