Blending our 25 years of security technology deployments at some of the nation’s largest public service organizations with our 25 years of commercial real estate property information services, SDI offers advanced security systems for the CRE industry at an affordable price point.

SDI has teamed with industry-leading product vendors to offer their cloud-based  access control platforms specifically geared for the real estate industry.  Our system provides building owners and tenants with enhanced video security for their properties at a low upfront cost.


Whether you have one office door or a thousand worldwide, you can’t always be there to guard it and manage access. Our approach lets you do it all—to allow entry, print badges, open doors, set schedules and see who’s in your building—from wherever you are (desktop or laptop, tablet or mobile device) through a single, secure web-based administrative interface.

SDI offers managed access control programs that eliminate the need to acquire your own software, infrastructure and devices. Building owners and tenants can select the level of security preferred for each point of access, and choose from a range of devices (card, fob, cell phone, smart locks). Quickly add and delete users, issue credentials, view access areas and unlock doors—from desktop or laptop, tablet or mobile device, through a single, secure web-based administrative interface.
