My baby refuses to come inside!

We rescued a husky around a year and a half ago. Up until 8 weeks ago, he's mostly been an inside dog-sleeping beside my bed every night. We have a fenced in backyard and he's refusing to set foot in the house. We had a burglary a few weeks before that and installed a wireless home security system. The door that he would use to enter the house has one of the sensors. I'm thinking that maybe it would be emitting a wirele frequency that's hurting his ears. My husband thinks I'm crazy but I am just grasping for straws at this point. I've tried "calming" chewables, enticing him with food lol. I just want him to want to come back inside with the family.
