The SECRUI Wireless Doorbell M520+F55 is a plug-and-play, battery-powered doorbell kit with two indoor receivers, 58 selectable chimes, adjustable 0–120 dB volume, colorful LED flash and a 300m (1000ft) wireless range for reliable home and small-business use.

If you want a straightforward replacement for a hardwired bell or an easy way to add an entry alert for multiple rooms, this SECRUI set combines long range, loud clear sound, and a visual LED cue in a compact package.

It also supports expansion with additional transmitters or receivers, making it flexible for apartments, houses, garages or small offices.

How loud is the SECRUI doorbell and can I adjust it for different rooms?

The receiver offers adjustable volume from silent (mute) up to 120 dB, so you can lower it for bedrooms or crank it up for noisy basements and workshops. Memory function preserves your chosen melody and volume after power loss, so you won’t need to reset it repeatedly.

• Volume range: 0–120 dB with mute option
• 58 built-in melodies to match room size or preference
• Memory recall retains last settings after outages
• Two receivers included to cover multiple rooms immediately

Will the signal reach every corner of my home or yard?

This SECRUI kit uses a strong wireless protocol for up to 300 meters (about 1000 feet) in open space, which covers typical single-family home layouts and many multi-level homes. Real-world range depends on walls and interference, but the system is designed to maintain a stable connection through common building materials.

• Ultra-long wireless range up to 300m / 1000ft (open area)
• Reliable signal through multiple rooms and floors

How easy is installation and can I customize chimes for different doors?

• Transmitter pre-paired for quick setup out of the box
• Selectable melodies let you set unique tones per door
