Core Solutions

Commercial Security Systems – Protect every site with video surveillance, intrusion detection, and real-time alerts. We design right-sized systems for single buildings and multi-site portfolios, integrating cameras, alarms, and monitoring for complete visibility.

Access Control – Control who enters, where, and when—without adding friction for staff or residents. We integrate credentials, badges, mobile access, doors, and gates to create secure, auditable entry experiences across campuses and portfolios.

Cloud-Based VoIP (Business Phone Systems) – Modernize calling with a flexible, cloud phone platform: desk phones, softphones, mobile apps, call routing, voicemail-to-email, and analytics. Keep teams reachable anywhere while reducing maintenance compared to legacy PBX systems.

Networking & Low-Voltage Cabling – Reliable connectivity starts with the foundation. We plan and install structured cabling, switching, and wireless that support today’s bandwidth and tomorrow’s growth—purpose-built for security devices and voice traffic.
