Direct answer
Phoenix and Scottsdale require permits for burglar/fire alarm systems that fall under their respective alarm ordinances, but that does not mean every standalone camera, detector, or smart-security device needs an alarm permit. Define the system type, monitoring or reporting path, property use, and actual jurisdiction first. Phoenix provides an official burglar and fire alarm permit page; Scottsdale provides current information through Scottsdale licenses.
Fees, renewal terms, response policies, and false-alarm assessments can change. Confirm the property's actual jurisdiction because a Scottsdale mailing address does not always mean the parcel lies within city limits. The installing or monitoring company should explain responsibility, but the property owner should retain the permit record.
