I couldn’t be happier with the service provided by DGA! From the very start, their professionalism and dedication stood out. The team was incredibly knowledgeable, helpful, and thorough in ensuring my shop’s security was exactly what we needed.

They went above and beyond to make the entire process smooth and stress-free. Not only did they install a top-notch alarm system, but they also made sure we felt safe and confident in its functionality. Their commitment to checking in regularly and ensuring everything runs smoothly is truly unmatched.

As the owner of a jewelry store, security is of the utmost importance, and DGA has given me peace of mind knowing my shop is well-protected. Their professionalism and attention to detail make their service invaluable.

I highly recommend DGA to anyone looking for a reliable, trustworthy, and supportive security partner. Thank you for making this investment completely worth it!

From the beginning Mike, Mark and all the Technicians were providing the best service.

I appreciate how quickly and vigiliently DGA follows up if there's an alarm including sending text messages since these days many people do not answer the phone or have their phones set to silent. That was a great idea!

Excellent company to work with. Efficient, trustworthy and on point. They always send someone before we are able to send out the email notifying them about an issue (Igor is a pleasure to work with!). Great customer service, highly recommend for any organization that needs a trustworthy and top of the line customer service for their security needs.
Thank you DGA!

The DGA Team were great to work with. There was a complicated tech issue on sight they were able to solve in one visit! Great job with Shawn the on-sight technician. He took time to describe and investigate beyond the scope of the initial request to solve the problem. Wow!! Thank you DGA!

DGA Security provides a 5-star service with both their customer service and their security system. The cameras are top-notch products, and the technician supervisor that they sent for our installation was very attentive to my requests. I would definitely recommend DGA to anyone wanting CCTV and alarm system.
