Commercial Security


Every DGA security system is custom-designed by an on-staff security consultant to provide the highest level of protection while meeting all specified standards and delivering unmatched overall value.

Our highly trained installation and service teams, our commitment to customer satisfaction, and our state-of-the-art monitoring center located in the heart of midtown Manhattan, inspire the confidence and peace of mind that has earned our customers’ trust and distinguished DGA from other New York security systems providers for over 40 years.

By constantly evaluating the latest technology and working to understand our customers’ evolving needs, DGA has developed an array of options and services to make security systems more effective and easier to use. DGA offers Web tools to review and manage key functions online and email alerts to keep you informed on the go. So DGA customers have 24/7 access to their security systems from home, from the road, from virtually anywhere.

DGA offers several value-added services to enhance your ability to monitor and secure your employees, customers, property and inventory:

Line Security: We constantly monitor your connection to DGA’s monitoring center. If it is interrupted for any reason, we will contact you and, if appropriate, the proper authorities.

Opening and Closing Services: DGA will track each time your alarm is armed and disarmed and, if you desire, our monitoring center will contact you when there are deviations from a schedule that you provide to us.

AgentCheck: In the event of an alarm, trained uniformed DGA agents are dispatched to your location to survey the situation.

Vault Services: DGA maintains two vaults in New York’s Diamond District to secure valuable property and inventory, including the DGA Vault & Business Center @ 580 Fifth Avenue, the standard for vault services.
