IF IT WAS JUST YOUR CAR IT COULD POSSIBLY BE A FREQUENCY FROM THE BUS, BUT SINCE IT WAS UR NEIGHBORS AS WELL THEN U WOULD ALL BE THE SAME FREQUENCY AND THEIRS WOULD TURN OFF AND ON WHENEVER YOU DID YOURS, PLUS MOST ALARMS NOWADAYS HAVE A ROLLING CODE SO THAT IT DOESNT HAPPEN...MOST LIKELY VIBRATION FROM THE BUS, IVE SET OFF MANY WITH STEREO SYSTEMS THAT WERENT VERY LOUD
