Douglas Security System installed a full CCTV and access control system at our family-owned retail store in Brooklyn. The installation was smooth, and the techs answered all our questions patiently. The quality of the cameras and user interface is top-notch. Best part? Their customer support after installation is just as great.

We hired DSS to upgrade the intercom and surveillance system across our apartment complex in Queens. The team was incredibly professional, punctual, and knowledgeable. Not only did they deliver exactly what we needed, but their pricing was very reasonable compared to other quotes we received. We feel much more secure now—highly recommended!
