Fit ledger — need → measured evidence

REPLACES THE MOTOR
3/4 HP ultra-quiet DC belt drive with a smart wall panel and two remotes in the box — this is the opener, not an add-on controller.
POWER CUTS
Battery backup keeps the door moving in an outage — the one failure a $29-$90 retrofit controller can never fix.
EYES INSIDE
Built-in 130-degree wide-angle camera with free live view in the myQ app; bulbs for the 2-bulb LED head are sold separately.
UNDER $250
$249 typical at retail — the LiftMaster equivalent is dealer-only at roughly $500-$600 before installation.
INSTALL REALITY
DIY-installable, or budget $100-$200 for a professional install — more if the door needs new springs or a 120V outlet.
RECURRING COST
Live view, open/close and alerts are free; saved clips need myQ Video Storage at $40/year (7-day) or $100/year (30-day).

  The catch — co-equal billing, always

It locks your garage into myQ permanently. The B4310 ships in the Security+ 3.0 generation, so no third-party controller — Meross, Konnected, Tailwind, ratgdo — will ever work with it. There is no HomeKit, Alexa and Google need a ~$3/month IFTTT plan that can only close the door, saved camera video runs $40-$100 a year, and most older Chamberlain remotes and keypads will not pair with this generation.

Dealbreaker? Runner-up №2 keeps your opener and your smart-home freedom ↓

  Every product has a catch. Verdicts that hide it are how bad buys happen.

Don't buy this if…

  • you need a complete garage door replacement (door panels + springs + motor) not just smart controls
  • you want a smart lock for a pedestrian garage side door, not the main overhead doorsmart locks dossier →
  • you have a manual (non-motorized) garage door with no existing opener
  • you want outdoor security cameras to monitor the driveway and garage exterioroutdoor security cameras dossier →

Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids

Why the Chamberlain B4310 is right for you

It avoids every trap below — and for family of 4, under $250, it is the pick because it delivers:

Trap 01

Check the learn button colour first

Chamberlain's December 2025 Security+ 3.0 firmware — every new Chamberlain/LiftMaster opener with a white learn button — blocks Meross, Tailwind, Konnected and ratgdo at the protocol level. Only myQ works. Yellow, purple, red or orange means Security+ 2.0, where third-party controllers still run. Look before you order.

Trap 02

The fee behind the camera

Hardware price is not the price on myQ openers. Saved video needs myQ Video Storage: $40/year for 7-day history, $100/year for 30-day, and Alexa or Google on myQ needs a paid IFTTT plan (~$3/month) that can only CLOSE the door. Every retrofit controller here — Meross, Konnected, iSmartGate, Tailwind, Genie — charges nothing recurring.

Trap 03

A controller is not an opener

Retrofit controllers cost $29-$142 and install in under 30 minutes, but they need an existing motorised opener (roughly post-1993, with safety photo-eyes) — they do not replace the motor. A full replacement opener is $249-$600 plus $100-$200 for a professional install. Different purchase, different class.
