Intercom & Buzzer Systems
Downtown Doors & Security installs and repairs intercom and buzzer entry systems across Brooklyn and Manhattan — audio and video intercoms for apartment buildings, offices, and multi-unit properties, integrated with electric strikes and maglocks so tenants and visitors can be seen, spoken to, and let in.
An intercom is how a building controls its front door: tenants answer, see or hear the visitor, and release the door. When the panel, handset, wiring, or door-release fails, tenants can't let anyone in — or the door won't secure.
We install and repair audio and video intercoms, lobby panels, in-unit stations, and buzzer entry, and can upgrade older systems to modern intercoms that release the door from a smartphone.
When you need it
- The buzzer or door-release stopped working
- A lobby panel or in-unit handset is dead
- Tenants can't hear or see visitors
- You want video entry or smartphone door-release
- An old intercom system needs replacing
How it works
- 1
Diagnose the system
We trace the panel, wiring, handsets, and electric strike or maglock to find where entry is breaking down.
- 2
Repair or upgrade
We repair the existing system or install a modern audio/video intercom with the door-release and features you want.
- 3
Test tenant entry
We confirm every station calls, answers, and releases the door, and that the door secures again after.
How pricing works
Every intercoms 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
Can you fix the buzzer that won't open my building's door?
Yes — a buzzer that won't release the door is a common repair. We diagnose the panel, wiring, and electric strike or maglock and restore entry.
Can I get a video intercom that works on my phone?
Yes. We install modern video intercoms that let residents see and release visitors from a smartphone, alongside traditional handset systems.
