Burglar alarms in the United States: prices, rules and what to check

A DIY burglar alarm kit with a hub and sensors costs approximately $100 to $220 in the United States, according to sellers' websites, October 2026. Whole-home systems with an outdoor siren and more sensors cost about $330 to $420.

Insurance and local rules

Some home insurance policies require a specified alarm to be installed and maintained, so check the policy wording before you buy. In Texas, state law regulates companies that install burglar alarms or provide security services, so check that a professional installer there is properly licensed. Alarm installation standards also require a backup power supply that keeps the system running when the mains fail, which matters for a Wi-Fi kit during a power cut.

Season and when to set it up

Nights are longest in the December to February winter, so get the system working before then. October gives you time to test the siren, the app and each sensor. Summer, from June to August, brings open windows and longer evenings, so check the window sensors in that season too.

What to write in your request

Say whether it is a house or an apartment, the premises area in square feet, and the number of doors and windows to cover. Add the system type (DIY or professionally monitored), the sensors and siren you want, whether you need installation, the city, and your budget. A cellular kit suits a home without reliable Wi-Fi.
