Chamberlain B4655T

Overview

The Chamberlain B4655T combines four features that many homeowners pursue separately: belt drive quiet operation, battery backup, built-in camera, and myQ smart control. Getting all four in a single factory-integrated unit is the primary appeal of this model. Rather than installing a camera separately or adding a smart hub later, everything ships together and works through the same myQ app.

This opener is designed for the homeowner who wants a complete, connected garage solution without patching together multiple devices. The belt drive keeps noise low in an attached garage. The camera adds visual awareness. Battery backup covers power outages. The myQ app brings all of it together on the phone.

The camera, the door controls, and the activity log are all in the same app. There is no second camera app to manage. There is no separate smart hub to configure. The B4655T ships as a complete system. Everything activates through a single myQ setup process during installation.

The activity log records every door event with a timestamp and the triggering device. Combined with the live camera feed, this gives a complete picture of garage activity. Homeowners know when the door opened, who triggered it, and what the garage looked like at the time.

The B4655T is a step above the B4643ST, which carries the same belt drive platform and camera but lacks battery backup. For homeowners in areas where weather-related outages are a real possibility, the B4655T is the more complete choice.

Drive Type, Motor, and Power

The belt drive system is the quietest common drive type for residential openers. The B4655T uses a reinforced belt on the rail rather than a metal chain. The belt moves the trolley without the vibration and mechanical noise that chain drives transmit through the ceiling and wall structure. In attached garages, this distinction matters every time the door opens or closes.

Colorado homes with garages attached to the main living space benefit particularly from belt drive openers. A bedroom above the garage, a home office beside it, or a kitchen on the other side of the wall all benefit from quieter cycling throughout the day. Belt drives do not produce the audible clank that can interrupt conversations or wake up people sleeping nearby.

The B4655T uses a DC motor with a lift force equivalent to 3/4 HP, per Chamberlain's published specifications. DC motors are not rated in traditional horsepower, but 3/4 HP is the published comparison figure for this model's lifting capacity. The DC motor also provides soft-start and soft-stop on every cycle: the door accelerates gently at the start and slows down before reaching the fully open or fully closed position. This reduces stress on torsion springs, cables, and hinges over time.

Battery backup is included. The backup system activates automatically during a power outage and allows the door to continue operating for a limited number of cycles until power is restored. This is a meaningful feature for Colorado homeowners, where summer storms and winter weather can cut power without much warning.

Smart Features, Security, and Safety

The integrated camera is one of the B4655T's most distinctive features. Built into the motor head unit, it provides a live view of the garage interior through the myQ app. Homeowners can check the garage in real time from anywhere with a phone signal. The camera sends motion-based alerts when activity is detected inside the garage, which is useful for households where the garage is a frequent entry and exit point.

Built-in Wi-Fi connects the opener directly to myQ without any bridge or hub. The myQ app provides full remote control, door status monitoring, real-time alerts, scheduling, and the camera feed all in one place. The setup is completed during installation and requires only a Wi-Fi password.

Security+ 2.0 rolling code technology changes the access code with each remote press. Replay attacks cannot work because the old code is never valid again. All Security+ 2.0 accessories pair with this unit, including wireless keypads and extra remotes.

UL 325-compliant photo-eye sensors ship with the opener and mount at the door base. An object crossing the beam during closing triggers automatic reversal. The motor also includes contact auto-reverse. An integrated LED light activates during each door cycle and carries its own 5-year warranty.

Is This the Right Opener for You, and How G Brothers Helps

The B4655T is well-matched for homeowners who want a belt drive opener with battery backup and built-in camera without adding separate devices. It is a step up from models like the B4643ST (no battery backup) and appeals to those who want outage protection alongside visual monitoring.

The camera is particularly useful in active households. Parents can check whether a teenager has arrived home. A homeowner working remotely can see who entered the garage. Package deliveries that go into the garage can be watched without being present. All of that comes through the existing myQ app alongside the door controls.

For homes with very heavy or oversized doors, the horsepower should be confirmed to ensure the B4655T is rated for the load. If the door weight is above average, a 1-1/4 HP model like the B6755T, which also includes a camera and battery backup, may be a better match.

The lifetime motor and belt warranties are a strong foundation for long-term ownership. The 5-year parts coverage adds further confidence.

The camera is factory-integrated into the motor head. It does not require a separate power cable or mounting step. The camera connects to the myQ app during Wi-Fi setup. Once connected, the live view is available from anywhere. The same setup also enables motion alerts, so the app notifies the homeowner when activity is detected inside the garage.

Wireless keypads and additional remotes are compatible through Security+ 2.0. They pair during installation. A keypad on the exterior wall gives household members PIN-based access without needing a remote. This is practical for family members who walk or bike, or for service providers who need one-time access.
