Commercial security systems for every New York City facility

A commercial security system usually combines access control, video security, alarm monitoring, and visitor management in one program. Access control governs entry, cameras verify what happens, monitoring provides real-time response, and visitor management handles guests and contractors. In New York City, most businesses run these across multiple floors, entrances, and sometimes several locations.

Yes. Kastle monitors systems around the clock from its security operations center, so a trained professional receives every alarm and access event at any hour. Round-the-clock monitoring is especially critical for after-hours break-ins, when no one is on site to respond.

Almost any commercial property. Kastle protects office buildings, multifamily communities, retail, healthcare, government, and construction sites across New York City. The system scales from a single entrance to a full portfolio, so it fits both small businesses and large enterprises.

An access control system checks a credential, such as a mobile phone, keycard, or fob, against a permissions database before it unlocks a door. If the credential is valid for that door and time, it grants entry and logs it. If not, the door stays locked, and the attempt is recorded. Building teams receive a clear audit trail of who entered where and when.

Video surveillance is the camera layer that records and verifies activity. Monitoring is the people and process that watch those feeds and alarms and act on them. Cameras without monitoring create a record after the fact. Monitoring turns that footage into a real-time response.

A visitor management system authorizes guests, contractors, and deliveries before they arrive and gives them time-limited access once inside. It verifies identity at check-in, alerts the host, and keeps a record of who visited. For a New York City building with heavy daily traffic, it closes the gap permanent credentials don't cover.

Yes. Kastle runs an open platform that connects with third-party readers, cameras, credentials, and building systems. Existing cameras can often plug into a Kastle gateway for cloud management and analytics. You can upgrade your building in phases instead of doing it all at once.

Multi-tenant, multi-floor buildings need access across lobbies, elevators, loading docks, and shared amenities. The installation has to account for that complexity from day one. Ask whether the company that installs the system also monitors and maintains it after deployment. A managed provider covers installation and long-term maintenance under the same contract.
