BCone Pool Alarm System — pool unit, home unit, app, and packaging

Most pool owners don't know
this product exists

Fences and covers are great — but what happens when the gate is left open, the cover is off, or someone slips through? A pool alarm is the safety layer that most families are missing.

The gap in pool safety no one talks about

Nearly 70% of toddler drownings happen during non-swim time — moments when no one expected the child to be near the water. A fence helps. Supervision helps. But what about the 10 seconds when you step inside to grab a towel?

Pool alarms exist specifically for those moments. They're recognized by the CPSC, required by law in several states, and recommended by the American Academy of Pediatrics. Yet most families with a backyard pool have never heard of them.

BCone is designed to fill that gap.

Drowning doesn't wait for you to be ready

It happens fast. It happens silently. And it almost always happens when no one expected it.

"The pool doesn't care if you were only gone for a minute."

Don't Wait — Shop BCone

This isn't about fear.
It's about being realistic.

You don't need to be paranoid to want protection. You just need to be a parent, a grandparent, a pet owner — or someone who has people you love near your pool.

Parents of young children

Your kids are fast, curious, and fearless. You can't watch every second of every day — and you shouldn't have to do it alone. BCone watches the water when you step away.

"I just want something that alerts me if my toddler somehow gets to the pool when I'm not looking."

Grandparents

When the grandkids visit, the pool becomes the center of the action — and the worry. You want to enjoy the time, not spend it in constant anxiety.

"My grandkids visit every other weekend. The pool is fun, but it scares me when they're running around outside."

Pet owners

Dogs fall into pools more than people realize — especially older dogs, small breeds, or pups who can't find the steps back out. BCone detects pets too.

"Our dog fell into the pool once when we weren't home. We were lucky. I don't want to rely on luck again."

Hosts and homeowners

Pool parties, neighborhood kids coming over, guests who don't know your yard — having an alarm protects everyone, including you from liability.

"The neighbor's kids are always peeking over the fence. I need to know if anyone enters my pool when I'm not there."

How BCone protects your pool

No complicated setup. No subscription. Just reliable protection that works automatically.

1

Place in the pool

The pool unit floats on the water's surface and continuously monitors for disturbances. It takes less than 5 minutes to set up.

2

Connect to WiFi

Pair the home unit with your WiFi network through the Lifebuoy app. One-time setup — then it runs on its own.

3

Water entry detected

When something or someone enters the pool, the sensor detects the disturbance in the water surface and triggers the alarm.

4

You get alerted instantly

The Pool Unit and home unit both sound a loud alarm. Your phone gets a push notification

Why families choose BCone instead of
doing nothing

Because "I'll just keep an eye on them" is a plan until it isn't.

Because eyes can't be everywhere

You can be the most attentive parent in the world and still get distracted. A phone call, a doorbell, another child calling for help. BCone fills the gaps your attention can't.

Because fences aren't foolproof

Gates get left open. Kids climb. Dogs find gaps. A fence is a barrier — an alarm is the alert when the barrier fails. The best safety plans have layers.

Because accidents happen off-hours

Most pool incidents don't happen during swim time. They happen when no one expected anyone near the water — early morning, after dark, during nap time.

Because you can't always be at home

With WiFi alerts on your phone, BCone tells you if something enters your pool even when you're at work, running errands, or asleep upstairs.

Because liability is real

If a neighbor's child or a guest's pet falls into your pool, you may be held responsible. A pool alarm is both a safety measure and a smart precaution.

Because the cost is tiny vs. the risk

For less than the cost of a pool cleaning, you add a critical layer of safety that works 24/7, 365 days a year. The question isn't "can I afford this?" — it's "can I afford not to?"

Real situations where BCone makes the difference

These aren't hypotheticals. These are the everyday moments that pool owners face — the ones that happen faster than you can react.

You step inside for a towel

The kids are playing in the yard. You run inside to grab towels. In those 90 seconds, your toddler wanders toward the pool. BCone detects the water entry and alerts you immediately.

You take a phone call

You're on the patio, watching the pool. A work call comes in. Your attention shifts for three minutes. Your child silently slips into the shallow end. BCone sounds the alarm before you even notice.

It's nighttime and the pool is unattended

Everyone's inside. The pool gate was left open. Your dog, a visiting child, or even wildlife enters the pool overnight. BCone alerts your phone and sounds the alarm at the house.

Neighbor kids come over uninvited

You're not home, but the kids next door found a way into your yard. Before they even get fully in the water, BCone detects the entry and sends you a notification.

A pool party winds down and not every child is accounted for

Parents start chatting. Kids scatter around the yard. One child walks back toward the pool unnoticed. BCone is the layer that doesn't get tired, distracted, or assume someone else is watching.

Designed for real life, not just for demos

False alarms are the #1 concern we hear. That's exactly why BCone's detection algorithm was engineered to tell the difference between a child falling in and wind, rain, or pool equipment.

Advanced wave-pattern detection

BCone doesn't just detect any splash. Its algorithm analyzes the specific wave pattern caused by a body entering the water — filtering out wind ripples, rain, and pool pump activity.

Swim mode for planned pool time

When the family is actively swimming, simply activate swim mode through the app or the home unit. When no movement is detected for several minutes, the system will reactivate automatically — so your pool is never left unprotected.

Five sensitivity levels

Adjust BCone's sensitivity from the app to match your pool's environment. Reduce sensitivity if you have water features or live in a windy area. Increase it for maximum protection.

Do Not Disturb mode for nighttime

Use DND to avoid false alarms during the night from environmental factors, while the system continues to monitor and alert through the app.

Easy to reset, easy to manage

If the alarm does trigger, resetting is instant — from the home unit, the app, or even with a voice command through Alexa.

BCone pool alarm system

5 minutes. No tools. No technician.

If you can connect a device to WiFi, you can set up BCone. Seriously — that's the hardest part.

BCone system with app and packaging
No drilling, no wiring, no modifications

The pool unit floats. The home unit plugs in via USB-C. That's it. No holes in your pool deck. No electrician needed.

Guided app setup

The Lifebuoy app walks you through every step with clear instructions. Most families are up and running in under 5 minutes — including firmware updates.

Long-lasting battery

The pool unit runs on 2 standard AA batteries that last up to 18 months. The home unit has a rechargeable battery with USB-C charging — no special batteries required.

Works with Alexa

Connect BCone to your existing smart home setup for voice-activated control throughout your house.

Works with virtually any residential pool

In-ground, above-ground, saltwater, chlorine — BCone is designed to work in the real world, not just in a laboratory.

In-ground and above-ground pools

BCone works with all standard residential pool types — plus spas, hot tubs, and garden ponds. The floating sensor adapts to any water surface.

Covers up to 20' × 40' per unit

One pool unit covers most standard residential pools. For larger pools or L-shaped configurations, connect up to 4 pool units to a single home unit.

100 ft (30 m) range to the home unit

The pool unit communicates wirelessly with the home unit from up to 100 feet away — more than enough for most home setups.

IP68 waterproof certified

The pool unit is built to live in water. IP68 rated for continuous submersion. Rain, splashing, direct sunlight, UV, and pool chemicals — it handles it all.

Portable — take it on vacation

BCone is easily detachable and portable. Take it with you to vacation rentals, the grandparents' pool, or anywhere your family swims.

The home unit receives signals from the pool unit at up to 100 feet — double the range of the previous generation for reliable whole-yard coverage.

BCone is one important layer — not the only one

We believe in honest safety. BCone is not a replacement for supervision, fencing, swim lessons, or good judgment. It's a critical additional layer that works when other layers fail.

No single product can prevent every drowning. But a well-designed alarm system can give you the seconds you need to respond — and those seconds can make all the difference.

We say this because we're genuinely committed to pool safety, not just selling a product. We want families to take a layered approach:

👁️ Active adult supervision — always the first line
🚧 Pool fencing with self-closing, self-latching gates
🏊 Swimming lessons for children (and adults)
🚨 A certified pool alarm like BCone
🫁 CPR and first-aid training for caregivers
🔒 Pool covers when the pool is not in use
BCone — part of your layered pool safety plan

Frequently asked questions

Everything you need to know before you buy.

BCone uses a surface-wave detection sensor that sits in the water. When a person, child, or pet enters the pool, the wave pattern generated is significantly different from wind, rain, or pool pump activity. The sensor analyzes this pattern and triggers the alarm within seconds of water entry.
BCone's algorithm is specifically designed to distinguish between natural water disturbances (rain, wind, pump cycles) and the displacement pattern created by a body entering the water. You can adjust the sensitivity level from the app to match your environment. You can also use DND mode to avoid false alarms during nighttime hours.
Yes. BCone has a smart swim mode that you can activate from the app, the home unit, or through Alexa. When no movement is detected for several minutes after swimming, the system reactivates automatically — so your pool is never left unmonitored accidentally.
A single BCone pool unit covers pools up to 20' × 40' (6m × 12m). For larger pools, L-shaped pools, or pools with separate spa areas, you can connect up to 4 pool units to a single home unit for complete coverage.
The pool unit communicates with the home unit via a direct wireless radio signal — no WiFi needed for the alarm itself to work. WiFi is used for smartphone notifications, Alexa integration, and remote monitoring through the app. Even without WiFi, the pool-side and home-unit alarms will still sound. Note: a strong WiFi connection near the pool area is recommended for the best app experience.
The pool unit runs on 2 standard AA alkaline batteries that last up to 18 months under normal use. The home unit has a rechargeable battery charged via USB-C — no need to replace it. The system alerts you when the pool unit battery is running low. For best performance, we recommend using Lifebuoy AA batteries.
Automatic cleaners and water features may cause false alarms. If your pool has a small waterfall, the system can perform well if the pool unit is placed far from the waterfall and sensitivity is adjusted accordingly. You can reduce sensitivity from the app to find the right balance for your pool setup.
Pool alarm requirements vary by state and local jurisdiction. Several states — including California, New York, Connecticut, and others — require at least one safety feature (such as a pool alarm, fence, or cover) for residential pools. Check your local building codes for specific requirements. Regardless of laws, a pool alarm is widely recommended by safety organizations as an important layer of protection.
ASTM F2208 is the national safety standard for residential pool alarms, developed by ASTM International and referenced by the U.S. Consumer Product Safety Commission (CPSC). It sets performance requirements for how quickly and reliably a pool alarm must detect water entry. BCone is NSF Certified to ASTM F2208, meaning it has been tested to detect pool entry consistent with the profile of a child one year of age or older.
BCone needs to float freely on the water surface to detect disturbances, so it cannot be used while a solid pool cover or solar cover is in place. When the cover is removed — which is when the risk is highest — BCone should be placed in the pool immediately. Many families make this part of their routine: cover comes off, BCone goes in.
BCone is the latest generation of our pool alarm system. Compared to the original Lifebuoy, BCone offers WiFi connectivity (vs. Bluetooth only), Alexa integration, an improved detection algorithm, double the wireless range (100 ft vs. 50 ft), IP68 waterproof certification, support for up to 4 pool units, and a 3-year warranty (vs. 1 year). BCone is our recommended product for most families.
Yes. BCone's sensitivity is tuned to detect the water disturbance created by animals as well as children. Dogs, in particular, create significant displacement when entering the pool. While very small animals may not generate enough disturbance, BCone will detect most family pets.
Yes. BCone is designed to be easily detachable from its anchor point. You can take it with you on vacations, to relatives' homes, or anywhere your family will be around a pool. Just place it in the water, connect the home unit, and you're protected.
