Strategic guard placement for optimal response toalarms in security games

We introduce a Security Game with a single static guard that is supported by a number of spatially imperfect alarms. We model this setting with two non-cooperative games modeling two different strategic interactions between a Defender and an Attacker. In the first one the Defender has to respond to an activated alarm given its current position (Alarm-Response Game). In the second one, the Defender has to determine the best static placement from which undertakes any alarm response (Guard-Placement Game).
