Video intercom showing no picture? We find the fault and restore the image.
A black screen at the lobby, a frozen image upstairs, a dark or flickering display, or an IP panel that stopped reaching the app. We fix all of it, whatever brand you have and whoever put it in.
The panel is on but the image is solid black. A failed camera module, a loose ribbon connector, or a dead backlight behind the glass. Usually a repair at the lobby panel.
Solid black screen
The panel is on but the image is solid black. A failed camera module, a loose ribbon connector, or a dead backlight behind the glass. Usually a repair at the lobby panel.
Frozen image
One still frame that never refreshes. On IP panels the stream stalled. On analog systems the signal lost sync. A reboot can bring it back for a while, but the cause is in the wiring or the network.
Dim or flickering
The image is faint, washed out, or cuts in and out. A backlight or display driver on the way out, or a weak power supply browning out the panel.
Lobby dark, apartments fine
Apartment screens still show visitors, but the lobby panel is black. The vestibule camera or display failed, or the panel lost power, often after a renovation or water.
One apartment screen dark
The lobby looks fine on video, but one apartment screen is black. A failed apartment monitor, a broken cable to that unit, or a blown fuse on its riser.
Offline in the app
The IP panel shows offline. Tenants cannot answer from their phones, or the panel cannot reach its cloud. A network, firewall or account problem.
The six common culprits, in the order we check them.
A picture can die in four places: the lens, the display, the wiring and, on IP systems, the network.
Lobby camera module failure
The sensor or lens in the vestibule panel died, usually from weather, a seal that failed, or years of sun in a south-facing entry. We confirm it at the panel before ordering anything.
Display or backlight failure
The backlight, the display driver or the screen failed. Common over time in a dusty lobby. We test with a known-good panel. If the signal is there, the fix is a part.
Coax, network or ribbon cable fault
The signal breaks somewhere between camera and screen. Water in a riser, a cable crushed during building work, a corroded BNC, or a damaged jack in the apartment. We trace it with a cable tester.
Power supply or PoE failure
A transformer browning out causes a dim or flickering image. A dead PoE injector turns the panel off. Common after storms or work in the electrical closet. A straight part swap.
Network, firewall or cloud reach
On IP systems the panel cannot reach its cloud. A firewall change, a new router from the ISP, an address conflict, or an expired certificate on the firmware.
Firmware or account settings
Firmware out of support, a stale device registration, or a removed tenant account still referenced by the panel. Common after a management change or a billing lapse.
No picture, but the buzzer still works?
Visitors can still be buzzed in on audio while we fix the video. Tell us which screen is black and what the panel is, and we bring the right part on the first visit.
You do not need the original installer.
Most of our video intercom calls are on systems installed by companies that are long gone, and nobody knows the brand in the vestibule. We identify it on site, source the part, and get the picture back.
The video panels we service
Modern IP and app-based video intercoms across NYC, plus legacy analog video panels, older Mircom video and the composite systems common in pre-war buildings.
The lens, enclosure and camera side
The lens, the sensor and the vestibule enclosure take weather and vandalism the apartment screens never see. We carry camera modules for the common panels, replace cracked lens covers, and reseal exposed enclosures.
Repair first. We tell you honestly when it is time to upgrade.
When we repair
Most video calls are a repair: a camera module, a backlight, a cable fault, a dead power supply or an account fix. Straightforward once isolated, and you keep the system you have.
When we recommend replacing
The panel is a discontinued analog model with no parts left, it has failed several times in a year, or you were already planning video with phone answering. Then the money is better spent on the new system.

Four steps, and we test every view before we leave.
Phone triage
Black, frozen or offline, one apartment or the whole building, when it started, any recent power or network event. Five minutes tells us how fast to come.
Walk the chain
Lens at the panel, display at the panel, wiring to the head-end, then network and cloud on IP systems. The first 20 minutes finds the break.
Fix, or part on order
Standard camera modules, backlights, power supplies and popular panels are same-visit. For discontinued analog panels we restore audio-only operation while the part is on order.
