Burglar's Buddy

You create a magical area around you (10 ft), suppressing all mechanical or electronic intrusion alarms and alarms sensors in the area. Burglar alarms or other intrusion alarms within the affected area simply fail to function; sensors for intrusion alarm systems (such as motion detectors, IR detectors, pressure sensors, electric eyes, and so forth) also fail to function, sending no signal to monitoring stations. Video surveillance devices stop sending whatever the image they were photographing the moment when the spell was cast.
