Best pool alarms 2019: make your swimming pool a safer place

Having a pool alarm in your swimming pool can offer both a great security feature against intruders and vital safety if you have pets or children who could accidentally fall into your pool. That way, you can enjoy having a pool at home without fearing it could be a hazard to people or animals. With a good – if ear-splittingly loud – pool alarm, there’s no way anyone or anything will get into your pool without you knowing.

In our latest pool alarm test, we tried out eight extremely loud pool alarms in gallons and gallons of water, with golf balls, people and even a leaf blower to simulate windy weather, to see whether these alarms worked as intended. We tested the alarms with small, medium and large objects in the water as well as collected data on how loud they are. We found that the Brickhouse Pool Alarm is the best choice out there because it’s loud, affordable, easy to use, and reliably accurate.

Brickhouse Pool Alarm

Brickhouse Pool Alarm

Our choice for the best pool alarm of all

Reasons to Buy
Alarm is easy to turn off
Receiver works up to 300 feet away from the alarm
Reasons to Avoid
Must be installed on the side of your pool
Only works on pools up to 16 x 32 feet
It's big

Our choice for the best pool alarm of all, this Brickhouse pool alarm is pretty affordable considering some on the market cost upward of $200.

It was also accurate in our tests. The alarm sounded when we disturbed the water with a wet sweatshirt and when a person got into the water. However, it didn’t sound when we tossed golf balls in, earning it a grade of B-. It passed the wind-detection test with flying colors though, so you don’t have to worry about it going off on a particularly windy day.

The Brickhouse installs on the side of the swimming pool, so it won’t work if you have an above-ground pool. Yours needs to be an inground pool or deck-adjacent, and if it’s larger than 16 x 32 feet, you’ll need to invest in a second alarm.

The slider on the side of the alarm makes it easy to disable or turn off when it sounds. Also, the different alarm functions are clearly labeled, something we really appreciated as some units are confusing to use.

According to our tests, the Brickhouse puts out 100.5 decibels of sound, so you’re definitely going to hear it. You can install the remote receiver up to 300 feet away from the alarm as well – the longest range of any alarm we tested.

Like most of the alarms we tested, the Brickhouse requires batteries. You need six D batteries for the main unit, and while that might seem excessive, they last about a year with normal use. Overall, this alarm is affordable, accurate, easy to use and loud.

Poolguard Safety Buoy

Poolguard Safety Buoy

The Safety Buoy lives up to its name – it floats on the surface of the water and sounds an alarm when the water is disturbed

Reasons to Buy
Reasonably priced
Works on pools up to 18 x 36 feet
Fun and easy-to-see design
Reasons to Avoid
Quietest alarm we tested
Earned a B- for object detection
Takes a little finesse to turn off the alarm

The Safety Buoy lives up to its name – it floats on the surface of the water and sounds an alarm when the water is disturbed.

It’s shaped like a traffic cone too, which to us screams safety. You can attach it to the side of your pool with a string if you don’t want it floating out of reach.

In our tests, the Safety Buoy received a B- for object detection because while it picked up the sweatshirt we threw into the pool and a human getting into the water, it didn’t register any of the golf balls we tossed in.

Turning the alarm off once it sounds is a little more complicated than simply pressing a button: You have to touch the side of the buoy with the included magnetic key and hold it there for two or three seconds before the alarm will stop beeping. It put out 97.7 decibels of sound in our tests, making it the quietest alarm we reviewed. That being said, it’s still incredibly loud.

Like most of the pool alarms we tested, you can install the remote receiver up to 200 feet away from your pool. It is slated to work in pools up to 18 x 36 feet, which is on the larger end of the spectrum of the units we tested.

The buoy requires a 9-volt battery, which is easy to install and is supposed to last roughly one year, depending on how often the alarm sounds. This pool alarm is lightweight, fairly easy to assemble and use, and comes at a reasonable price to top it off.

Best wearable

Safety Turtle 2.0

Safety Turtle 2.0

This pool alarm is unique because rather than installing it or floating it on the surface of your pool, you wear it as a bracelet

Reasons to Buy
Is very accurate
Has three to five years of battery life
Works in any body of water
Reasons to Avoid
Older children could remove it
Not a security measure

This pool alarm is unique because rather than installing it or floating it on the surface of your pool, you wear it as a bracelet.

The alarm is an adorable, little, green turtle bracelet, so it’s perfect for young children or even pets, as it’s easy to affix to a dog collar. When submerged, the bracelet sends a signal to a remote receiver you can install up to 200 feet away from the pool, and the alarm sounds instantly.

The bracelet requires a plastic key to take it off, so there’s no way a pet or kid can remove it and slip into the water unnoticed. It doesn’t keep intruders out of your pool, but the Safety Turtle is great if you’re mainly worried about pool safety.

It earned an A+ in our object detection test because it went off every single time we submerged the device, but never when we flicked a few drops of water at it. If your kiddo likes to wash their hands up to their elbows, you might experience the occasional false alarm though. The receiver puts out 98.7 decibels of sound, and while that makes it the second-quietest pool alarm we tested, it’s still incredibly loud. For comparison, that’s about 10 decibels short of a rock band in concert.

The batteries on the bracelet last from three to five years, depending on how much you use them. They are sealed inside the bracelet, and you can’t replace them – instead, you have to purchase a new turtle bracelet when they die. However, the receiver plugs into an outlet and should outlast the bracelet.

The alarm on/off button on the receiver is also easy to use so you won’t be deafened by the sound of the alarm. The Safety Turtle is elegant in its simplicity and a great way to make sure your kids and pets are safe around the pool this summer.

Pool Patrol PA-30

Pool Patrol PA-30

The Pool Patrol PA-30 is very well designed, making it easy to change the alarm sensitivity

Reasons to Buy
Earned an A+ in our wind and object detection tests
Reasons to Avoid

The Pool Patrol PA-30 is very well designed, making it easy to change the alarm sensitivity.

While some in-ground pool alarms require you install an extra plastic plate if you hear too many false alarms, the Pool Patrol PA-30 has a base you simply rotate to the left or to the right.

This rotating base is also used to turn the alarm off when it sounds, which is quicker and easier than using an alarm that requires a key. The Pool Patrol PA-30 floats on the surface of the water, and it uses one 9-volt battery, which is easy to install under the rotating base.

Along with being very well designed, this alarm earned an A+ in our wind simulation tests and our object detection tests. It also works in pools up to 20 x 40 feet, the largest pool size of the alarms we tested.

Loudest alarm

SmartPool PE23 PoolEye AG/IG

SmartPool PE23 PoolEye AG/IG

Registering at 101.6 decibels, it's louder than a garbage disposal, a blender or a diesel truck passing you a mere 50 feet away

Reasons to Buy
Loudest pool alarm we tested
Reasons to Avoid
Installing/uninstalling the batteries is difficult

You’ll know if the SmartPool PE23 PoolEye AG/IG pool alarm goes off – registering at 101.6 decibels in our tests, it's louder than a garbage disposal, a blender or a diesel truck passing you a mere 50 feet away.

While the unit is cumbersome to put together, you shouldn’t have to do it very often because the batteries are slated to last one year before you have to change them. Since it’s a submerged pool alarm, it works best on in-ground pools, as you need to install it on a level surface with the neck submerged under water.

It works by detecting changes in water pressure and then sounding the alarm – loudly – when someone or something gets into your pool. This alarm works in pools up to 18 x 36 feet, and with its loud alarm, you can be sure your family is safe.

How do pool alarms work?

Most pool alarms work in one of two ways. Some float on the surface of your pool and sense when water is displaced – the sensors measure the disturbance and react to it, making the alarm go off. This type of alarm works in both above-ground and in-ground pools.

Other pool alarms mount to the deck of the swimming pool and use sub-surface detection to pick up on changes in water pressure, which cause the alarm to sound. These kinds of alarms work best for in-ground pools, though they also work if your above ground pool has a deck built around at least part of it. If you get this kind of alarm, make sure to read the instructions about where is best to install it based on the shape and depth of your pool.

There are also pool alarms that go off when they get wet, and they work best when attached to pets or children. That way if Junior jumps in the pool, you'll know.

The majority of the pool alarms we tested are battery-powered. Most are supposed to last for an entire year, but the more your pool alarm goes off, the more its battery life will suffer. Check your device every month or so to make sure the batteries haven’t died. You should also remove your pool alarm and take the batteries out during colder months while your pool sits unused. The alarms we tested all take 9V or D batteries.

What to look for when buying a pool alarm

When selecting a pool alarm it’s important to think about what you’re trying to accomplish. If you’re trying to keep intruders out of your backyard oasis, you should select a highly sensitive alarm that is discrete and loud. If an intruder can tell exactly where your pool alarm is, there’s a chance they’ll be able to disarm it.

On the other hand, if you have several small children spending time around your open backyard pool, you might want something a little different. If you know your pool alarm is probably going to go off several times a week because Junior jumped in the pool without adult supervision, you’ll want an alarm that is easy to turn on and off but still very loud. Look for alarms with buttons built in rather than those you have to use an external key to deactivate. If you have pets who are very young or even very elderly, you might want to consider a water-activated alarm. This way if your dog gets in the water – accidentally on purpose – you’ll know.

Do I need a pool alarm?

Some US states require certain kinds of pool alarms, but regardless of where you live, having an alarm can protect you from lawsuits. Even if you’re in a safe neighborhood and don’t have any young children yourself, there’s always the possibility of someone else’s children getting in to your pool without you knowing. An alarm can stop that from happening and stop any accidents before they start. This in turn protects you from the possibility of being sued if injuries happen on your property.

On average about 250 children 5 years old or younger die as a result of drowning, predominantly in residential settings, according to a 2000 Consumer Product Safety Commission report. Having a pool alarm is one way to make sure your children aren’t in the water unsupervised, and offers an emergency notification if accidents do happen.

Adam Katchmarchi, executive director of the National Drowning Prevention Alliance, said his organization encourages multiple layers of protection for children at the pool, including a pool alarm, gate alarm, floatation devices, swimming instruction and plain old-fashioned adult supervision. 

“Even though the alarms can be a little bit annoying, make sure you have them in place,” he said.

Some states or municipalities have laws and regulations stipulating what kind of pool alarm homeowners must have, so Katchmarchi said to do your research. California, for instance, requires new residential pools have two drowning prevention features, like a gate lock and a pool alarm.

“Sometimes kids are adventurous and you think you have all the barriers in place, but pool alarms are an extra layer of protection to have,” Katchmarchi said.

How much do pool alarms cost?

A pool alarm is a great way to keep your family safe, but it can be quite costly. The eight pool alarms we tested cost an average of $183. All but one of the devices we used cost more than $100, but you can expect each to have about one year of battery life. But if you’re concerned about a young member of your family falling in the pool or keeping intruders out of your backyard, an alarm is definitely worth the investment.

How did we test pool alarms?

Our hearing has suffered substantially, but we weren’t about to pass up on a day of fun in the sun. To test these pool alarms, we filled a kiddie pool that measured 8 feet in diameter and 18 inches deep. After installing each alarm, we threw golf balls into the pool to see if they would set it off. We also tossed in a large, soaking wet sweatshirt, followed by a person getting into the pool and walking around. 

Once we realized how loud these things really are, we decided it would be annoying if a little gust of wind set them off. As such, we used a leaf blower to create wind gusts to see if it set off the alarms too. 

One pool alarm, the Safety Turtle 2.0, goes off when it gets wet, so we dunked it multiple times to make sure it worked and flicked it with water to make sure it didn’t sound erroneously. Most manufacturers advertise their pool alarms make 85 decibels of sound or more, but to make sure, we used a sound meter set 25 centimeters away from each product and gathered noise output data. Our ears are still ringing, but it was worth it.
