Lock and Tech USA installs the full range of intercom technologies available on the market today — from classic analog and hardwired systems to modern digital, touchscreen, and cloud-connected platforms.
Audio Intercoms. Simple and reliable voice-only communication between entry points and units. Available in analog and digital configurations, with telephone entry and cell phone-only options for properties where simplicity is the priority.
Video Intercom Systems. Full two-way audio and video communication with live feed, video recording, and night vision. Visitors are visually verified before access is granted — eliminating guesswork and improving security.
Digital and Touchscreen Intercoms. Modern digital systems with touchscreen interfaces, digital scroll directories, and full smartphone integration. Ideal for multi-tenant buildings and commercial properties that need a clean, professional look.
Telephone Entry Systems. Integrate your intercom directly with existing telephone lines or cell phones. Visitors call specific units directly — no additional hardware required inside the property.
Hardwired Intercoms. The most reliable and tamper-resistant option. Hardwired systems never run out of power, provide greater range, and are significantly more difficult to intercept or bypass than wireless alternatives. Ideal for large residential buildings and commercial complexes.
Modern intercom systems from Lock and Tech USA offer far more than simple buzzing. Depending on the system, your installation can include any combination of the following features.
Two-way audio and video communication, and flexible call routing so calls reach the right person every time.
Live video feed, video recording, night vision, and full cell phone viewing — so you can see your visitors clearly from anywhere, at any time.
Remote door unlock and multiple access methods including PIN codes, RFID keycards, mobile app and Bluetooth credentials, and QR codes for guests. Full integration with electric strikes, magnetic locks, and door controllers.
Smartphone integration, cloud connectivity, and smart alerts — manage and monitor your intercom from anywhere in the world via mobile app.
Facial recognition for automatic entry, package detection, smart motion detection with intelligent filtering between humans, animals, and vehicles.
Apartment directory, multi-tenant support, and delivery management — everything you need to run a smooth, secure multi-unit building.
Custom call routing and call logging so every visitor interaction is tracked and directed to the right person.
Full integration with smart home systems, CCTV surveillance, and access control systems — all managed from one unified platform.
Intrusion alerts, encrypted communication, and security desk monitoring for properties that require professional real-time oversight.
Analytics, behavior detection, remote management dashboards, and the ability to control multiple buildings from a single platform — ideal for enterprise and high-security applications.

With a conventional intercom system, your visitor’s voice is the only way you have to verify their identity before you decide to buzz them in. A video intercom system eliminates all the guesswork, giving you an accurate and reliable way to determine who’s at the door before granting access.
If you have legitimate business with your visitors, all you need to do is press a button to let them in. If it’s someone more suspicious, you can discreetly call the authorities. Video intercom systems can also be customized to work between offices or within a single office for easier internal communication. They can replace keycards for additional security — adding a level of visual verification that a keycard alone can’t provide. The latest video intercom systems record, store, and time-stamp footage for later use if needed.
At home, you can add a significant level of security simply by building on something every home already has: a doorbell. Not only can you see who’s ringing, but you can check on package deliveries, monitor your porch during the holiday season, and deter would-be thieves. Once someone sees that you have a video intercom system, they are more likely to target another property over yours.
Hands-free use is a major benefit — you can see visitors and grant entry with the press of a button or through your smartphone app. The latest systems record, store, and time-stamp all visitor interactions, giving you reliable evidence when you need it.
Hardwired intercoms are the gold standard for multi-unit residential buildings and commercial properties. These systems have few vulnerabilities, never run out of power, provide greater range than wireless alternatives, and are extremely difficult to tamper with or eavesdrop on without direct physical access to the wiring. If maximum security and long-term reliability are your priorities, a hardwired intercom is the right choice.
Telephone entry intercoms integrate with your existing telephone system or cell phone to handle visitor access with no additional in-unit hardware. When a visitor arrives and presses a button on the door panel, your telephone rings with a distinctive tone. You answer, speak with the visitor, and grant or deny entry — all through your existing phone. Our systems support answering up to two gates or doors simultaneously.

An intercom amplifier provides the control, power, and signal amplification needed to maintain clear communication throughout a building’s intercom system. Poor audio quality, missed calls, and garbled sound are often caused by a failing amplifier or a bad connection — not the intercom system itself. Lock and Tech USA can bring new life to an intercom you thought was beyond repair by replacing the amplifier with a high-quality unit. Built with premium components and high-grade technology, our amplifiers are designed to last and deliver reliable performance. Contact Lock and Tech USA today to find out more about amplifier replacement or a full intercom system upgrade.
