Security Systems & Access Control
Downtown Doors & Security designs and installs commercial security systems across Brooklyn and Manhattan — access control and keyless entry, intercom and buzzer systems, magnetic locks and electric strikes, and camera/CCTV systems. We help businesses and buildings control who gets in and keep a record of it.
Security and access control is about managing entry to a building or space: who can open which doors, when, and with what credential — plus the cameras and intercoms that let you see and speak to visitors.
We install access control and keyless entry (including cloud-based systems), intercom and buzzer entry, magnetic locks and electric strikes, and camera/CCTV systems for offices, retail, and multi-unit buildings.
When you need it
- You want keyless or credential-based entry instead of physical keys
- A building needs intercom or buzzer entry for tenants and visitors
- You need to restrict access to certain doors, areas, or hours
- You want cameras to monitor and record entrances and common areas
- You're upgrading an old or failing access or intercom system
How it works
- 1
Assess the site & access needs
We map the doors, entry points, and who needs access to design a system that fits how the building actually operates.
- 2
Design the system
We recommend the right mix of access control, intercoms, locks, and cameras — scalable as needs grow.
- 3
Install & integrate
We install and wire the hardware, integrate it with your doors and locks, and configure credentials and permissions.
- 4
Train & hand over
We walk you through managing users, credentials, and footage so the system is genuinely usable day to day.
How pricing works
Every security & access control job is priced after a free on-site assessment — no guesswork and no surprises. We diagnose the real issue, explain your options in plain language, and give you clear pricing before any work begins.
Frequently asked
Do you install cloud-based access control?
Yes. We install cloud-managed access control that lets you add or revoke credentials and view activity remotely, as well as traditional on-site systems.
Can you integrate cameras, intercoms, and door locks together?
Yes. We design access control, intercom entry, magnetic locks or electric strikes, and cameras to work together as one system for your building or business.
