Security Systems for Williamsburg and Brooklyn Homes and Businesses

B & G Locksmith installs security cameras, video intercoms, access control, and buzzer systems for Williamsburg apartments, Brooklyn storefronts, and commercial buildings across all five boroughs. We work out of our counter inside B & G Hardware at 210 Roebling St. You can walk in to talk through your options, or we can come to your door. Either way, you get a real locksmith - not a dispatcher reading from a script.

What security systems does B & G Locksmith install in Williamsburg and Brooklyn?

We handle the full range of security hardware that homes and businesses in this neighborhood actually need.

• Security cameras: We install IP camera systems from Hikvision and Dahua. These include dome cameras, bullet cameras, and PTZ models. We run cable, mount cameras, configure the NVR or DVR, and set up remote viewing on your phone. A basic 4-camera system with a recorder runs roughly $800 to $1,500 installed, depending on camera count and how long the cable runs are.
• Video intercoms: We install Aiphone, DoorBird, and 2N video intercom systems for single-family homes, apartment buildings, and mixed-use buildings. A single-door video intercom with one indoor monitor starts around $300 to $600 installed. Multi-tenant systems with multiple call buttons and indoor stations are quoted by the job.
• Access control: For landlords, supers, and business owners who need to manage who enters a building, we install keypad and card-reader systems using Schlage and Alarm Controls hardware. These systems use electric strikes or magnetic locks and can log entry activity. Good fit for offices in Downtown Brooklyn, multi-unit buildings in Bed-Stuy, or storefronts in Bushwick.
• Buzzer and intercom upgrades: Older buildings in Greenpoint and Williamsburg often have outdated buzzer wiring. We upgrade existing intercom systems or replace them entirely.

How does the security system installation process work at B & G Locksmith?

The process is straightforward. It starts with a conversation - either at our counter on Roebling St or over the phone. We ask about the property type, how many entry points you have, and what you are trying to solve: package theft, after-hours access, liability coverage for a business, or general building security.

From there we do a site assessment. For camera systems, that means walking the property to figure out camera placement, power sources, and where to run cable. For intercoms and access control, we look at the door hardware, the existing wiring if any, and the type of lock or strike that will work with the frame.

Installation is done by our own locksmiths - not subcontractors. We mount, wire, configure, and test everything before we leave. We also show you how to use the system and how to pull footage or adjust settings on your phone. Most residential camera jobs take half a day. Access control and intercom installs vary by building size but are typically done in one visit.

If you already have a system and just need a repair or upgrade, we handle that too. We work on existing Hikvision, Dahua, and Aiphone systems regularly.

Why hire a Williamsburg storefront locksmith for security systems instead of a national chain?

A few practical reasons that matter in Brooklyn.

• We know the buildings here. Pre-war walk-ups in Williamsburg and Greenpoint have narrow door frames, old buzzer wiring, and masonry walls that make camera and intercom installs more involved. We have dealt with all of it.
• Hardware is on the shelf. Because we operate out of B & G Hardware, we stock door hardware, strikes, and intercom parts. We are not waiting on a supplier to ship something before your job can move forward.
• No call center. When you call or walk in, you talk to a locksmith. If you have a question about which camera is right for your back gate or whether a magnetic lock will work on your steel door, you get a direct answer.
• We also do the locks. Security cameras and intercoms work best when the door hardware is solid. If your building also needs a lock change, a high-security deadbolt, or a new cylinder, we handle it in the same visit. That matters for landlords and supers managing multiple units in East Williamsburg or Bed-Stuy.

Frequently asked questions

Can I add a video intercom to my Brooklyn apartment building?

Yes. We install wired and wireless video intercoms in buildings of all sizes. Aiphone and DoorBird are two brands we work with regularly. A single-unit video intercom starts around $300 to $600 installed, and multi-unit systems are quoted by the job based on the number of call stations and indoor monitors needed.

Do you install security cameras for small businesses in Williamsburg?

Yes. We install Hikvision and Dahua IP camera systems for storefronts, restaurants, and offices throughout Williamsburg and the surrounding neighborhoods. A basic 4-camera setup with an NVR typically runs $800 to $1,500 installed, depending on camera type and the length of cable runs.

What is the difference between access control and a smart lock?

A smart lock replaces your existing deadbolt and is controlled by an app, keypad, or fob. Access control is a broader system, often using a card reader or keypad wired to an electric strike or magnetic lock. Access control is better suited for buildings or businesses that need to manage multiple users and keep an entry log over time.
