Smart doorbells and intercom systems have become essential home security features for Aiken homeowners. Devices like Ring, Nest, and Eufy video doorbells let you see and speak to visitors from anywhere using your phone, while whole-house intercom systems provide convenient room-to-room communication. But these devices depend on reliable electrical connections to function properly.
Many video doorbells require a hardwired connection to a doorbell transformer that supplies the correct voltage. If your existing transformer is too weak, too old, or missing entirely, the doorbell will not charge, will drop video quality, or will fail to ring at all. Unity Power & Light handles the complete electrical side of intercom and smart doorbell installation throughout Aiken, SC -- from transformer upgrades and low-voltage wiring to dedicated circuit installations for advanced intercom systems.
What We Install
From basic video doorbells to multi-unit intercom systems, we handle every type of doorbell and intercom wiring project.
Video Doorbell Wiring
Hardwired installation for Ring, Nest, Eufy, and other video doorbells. We verify or upgrade your doorbell transformer to meet the manufacturer's voltage and VA requirements so the device charges reliably and streams video without interruption.
Doorbell Transformer Upgrades
Most older Aiken homes have 10VA or 16VA transformers -- too weak for modern video doorbells that require 16VA to 30VA. We replace your existing transformer with the correct rating and verify the wiring between the transformer, doorbell button, and chime.
Low-Voltage Doorbell Wiring
Running new 18-gauge or 16-gauge thermostat wire from the transformer to the doorbell location. Required when adding a doorbell where none existed, relocating a doorbell, or replacing corroded or damaged wiring in older homes.
Wired Intercom Systems
Multi-room wired intercom installation for larger homes. We run the communication wiring between stations, connect power supplies, and configure the system for room-to-room and door-to-room communication.
Gate & Entry Intercom Systems
Intercom systems for gated driveways and controlled entry points. We wire the outdoor station, indoor monitor, and electric gate release so you can identify visitors and grant access without walking to the gate.
Multi-Doorbell Installations
Homes with front and back doors, side entrances, or detached garages often benefit from multiple doorbell cameras. We wire each location with its own transformer connection and ensure all devices work independently on your network.
Our Installation Process
Evaluate Existing Wiring and Transformer
We inspect your current doorbell wiring, test the transformer output voltage and VA rating, and check wire condition from transformer to doorbell location. Many older homes in Aiken have doorbell wiring that has degraded over decades or transformers that no longer meet modern device requirements.
Upgrade or Install Transformer
If the existing transformer is undersized or missing, we install a new transformer rated for your specific device. Ring Pro requires 16-24VAC at 30VA minimum. Nest Hello requires 16-24VAC at 10VA minimum. We match the transformer to the manufacturer's exact specifications.
Run Wiring and Mount Hardware
We run new low-voltage wiring as needed, mount the doorbell bracket or intercom station at the correct height, and make all electrical connections. For video doorbells, we ensure the mounting angle provides optimal camera coverage of your entry area.
Test and Verify Operation
We power up the system, verify the transformer is delivering correct voltage at the doorbell, test the chime or intercom communication, and confirm video streaming works. We walk through the app setup with you so you know how to use every feature.
Why Professional Installation Matters
Smart doorbells and intercoms involve electrical work that goes beyond simple mounting. Here is why professional installation matters.
Transformer Compatibility
Every video doorbell model has specific voltage and VA requirements. An undersized transformer causes battery drain, video lag, and missed notifications. An oversized transformer can damage the device. We match your transformer precisely to the manufacturer's specifications, ensuring reliable long-term operation.
Proper Low-Voltage Wiring
Doorbell wiring carries 16-24 volts AC, which is low voltage but still requires proper installation techniques. Loose connections cause intermittent failures. Damaged insulation can short against metal framing. We use correct gauge wire, secure connections, and proper routing to ensure years of trouble-free operation.
Code Compliance
The transformer that powers your doorbell connects to a 120-volt circuit inside your home. That connection must meet South Carolina electrical code -- proper wire nuts, secure mounting, accessible junction box. DIY installations often violate these requirements, creating hidden fire hazards behind walls.
Reliable Performance
A security device that works intermittently is worse than no device at all because it creates a false sense of security. Professional installation ensures your video doorbell or intercom system operates consistently, charges properly, and alerts you every time someone approaches your door.
Intercom & Smart Doorbell Installation Pricing
Unity Power & Light provides flat-rate pricing for all doorbell and intercom installations. You will know the exact cost before we begin -- no hourly billing and no surprise charges.
The final price depends on whether existing wiring is present and in good condition, the distance from the transformer to the doorbell location, the number of devices being installed, and the specific power requirements of your chosen device.
