New to home security? Start with The Ultimate Guide to Home Security , which maps all our guides. Most burglaries are crimes of opportunity, and opportunity is mostly physical: an unlocked door, a weak latch, a dark side yard, a house that looks empty.

Professional monitoring is the part of an alarm system you pay for every month, and the part people understand least. This guide explains what happens between a tripped sensor and police arriving, how verification cuts false alarms, what you get over self-monitoring and when it is worth the cost. It is part of our complete guide to home security alarm systems . What happens when an alarm trips ConsumerAffairs describes alarm monitoring as a paid service that connects your system to a response center that watches for threats around the clock. In outline: A sensor trips and the panel sends a signal over Wi-Fi, cellular or both. An agent at the monitoring center follows a verification protocol, which differs for burglary, fire or carbon monoxide, and duress alarms. The agent tries to confirm the alarm. Frontpoint says personnel contact you on one of two pre-arranged numbers, and SimpliSafe says agents ask for your safe word. If you do not answer or give the wrong word, the center ...

New to home security? Start with The Ultimate Guide to Home Security , which maps all our guides. A home alarm system does three jobs: it detects a problem, it makes noise or sends an alert, and, if you pay for it, it gets a person to respond. This guide explains the parts, the main types, how the signal travels and what to check before you buy. It is the starting point for our alarm guides on sensors , professional monitoring , wireless alarms , pet-friendly systems and smoke and CO alarms . How an alarm system works ConsumerAffairs describes a home security system as a household tripwire: sensors watch doors, windows, rooms and hazards, then report to a central hub. When a sensor trips, the control panel checks whether the system is armed and starts the response you set up: a siren, an app alert, a signal to a monitoring center, or all three. Wireless sensors send the signal by radio, and wired ones through installed wiring. The panel then sends the event through Wi-Fi, cellular...
