• STRONG COMPATIBILITY: The Briidea doorbell extender works with up to two doors, perfect for front and back doors. It's compatible with wired doorbells but not compatible with RING, video, or intercom systems. No wiring needed—just plug it in for easy setup
• DUAL DOOR LIGHT ZONE REMINDERS: The upgraded receiver features a dual-row alarm light design: the top row flashes green to indicate visitors at the front door, while the bottom row flashes red for the back door. These visual cues make it easy to pinpoint which door is receiving a visitor
• LONG RANGE COVERAGE & WIRELESS PAIRING: The new Briidea ring doorbell extender offers an impressive 650ft wireless signal range (open area), ensuring you can clearly hear the doorbell from any corner of your home, never missing a visitor
• SMART ALERT MODES: Supports 3 alert modes: sound only, light only, or sound light (default mode). It also offers 20 different chimes with three adjustable volume levels (120dB / 90dB / 50dB) to meet the needs of noisy garages, quiet offices, or users with hearing impairments
• EASY OPERATION & WIRELESS PAIRING: The receiver features four simple buttons for easy operation. It supports wireless pairing, with green and blue lights flashing alternately to indicate successful pairing. When the battery is low, the green lights will flash alternately, so you'll know it's time to replace the batteries (requires 2 AAA batteries, not included)
