Check with friends or neighbors for recommendations on reliable companies.

Find out how quickly the alarm company will install your system after purchase. See if the company sells systems faster than they can install them.

Determine how quickly they respond to requests for service after installation. Ask for references from some of their customers who have required service and call and talk to these people.
Ask about warranties.

Obtain quotes from at least three different companies.

Ask the alarm company what screening they do when hiring their alarm installers and salespeople. You want a company that screens for criminal backgrounds/records, etc.

Call your local police department and ask how long it takes them to respond to a home security system alarm. Don&squot;t be surprised if the estimated response time is as long as an hour. Also ask if there are any fines for false alarms.

Lastly, when comparing prices remember to compare detection coverage and features. Not all alarms are created equal.
