The 11 Best Pool Alarms


Whether you have in above-ground pool or an in-ground pool at home, kitting it out with a proper pool alarm is vital.

If someone who can’t swim – a toddler or a pet, for instance – falls into the pool, the sensor will trigger a siren so you can save them from drowning. The best pool alarm can literally be a life saver.

Now, as with all pool equipment, you’ll soon find that you’re overwhelmed with options when you’re looking for swimming pool alarms. Today, we’ll be giving you a snapshot of all the strongest models in this space. We’ll highlight where they stand and fall so you can make the best-informed decision for your needs.

Now, while this is a reasonably straightforward buying decision compared to some pool equipment, you’ll still benefit from paying attention to a few key pointers:

  • Type of pool alarm: There are 3 main types of pool alarm. A standard pool entry alarm features underwater sensors mounted on your pool walls and surface sensor alarms floating on the surface of the pool water. If anyone or anything enters the pool, this movement triggers an alarm. With gate alarms, you’ll mount a magnetic sensor to any gates or doors giving onto your swimming pool. When the gate is opens, an alarm is triggered. You can also find user entry alarms. These are wearable alarms ideal for children. If the band the child is wearing gets wet, an alarm will sound. The alarm will detect any type of water, not just pool water.
  • Ease of use: The best pool alarm is useless if it’s not easy to operate. You should check plenty of user reviews to check there is no issue with false alarms caused by excessive sensitivity. We draw your attention to any shortcomings in this area in our reviews.
  • Volume: All that counts here is being able to hear the alarm from the distance that you need. Noise ratings are expressed in decibels, and most of the best pool alarms tend to have sirens rated at 85 decibels.
  • Range: The receiver for pool alarms will only work within a given distance. You’ll need to think about the distance between your house and the swimming pool to ensure you have no issues in this regard
  • Smart functionality: Some of the pool alarms on our shortlist come with Bluetooth connectivity, allowing you to take control using an app on your smartphone. Only you know if you would appreciate this type of remote control, or whether you would find it an extra layer of confusion
  • Type of pool: Make sure that the alarms on your shortlist are suitable for your swimming pool. Some only work with above-ground pools, while others are designed for in-ground pools. You’ll find some with size restrictions, too. As with all elements of your buying decision, check closely for compatibility before committing to purchase

OK, with that framework in place, you should be perfectly positioned to explore the best pool alarms out there. See what you think of the top 11  pool alarms at a range of different price points and styles.

You get a pair of these sensors in each pack, so buy according to how many area you need to alarm. In the event of any of these doors or windows being opened, you’ll receive an instant notification on your smart phone.

Despite all this smart functionality, you won’t be locked into any contracts, and there are no monthly fees to pay either.

Due to the wireless nature of this set-up, you can quickly and easily move the sensors if required.

Unlike some more complicated systems, this compact gem is straightforward to install, so you’ll be up and fully protected right out the box. You won’t cause any damage to your pool during installation either.

The manufacturer states that this device should be considered as additional pool security rather than a guaranteed life-saving device. You should still take all reasonable precautions from proper supervision and gates through to locks and pool covers.

The transmitter floats in the pool on the surface of the water.

We found a handful of complaints from users concerning the sensitivity of this unit.

One of the key selling points here is the fact you don’t need to carry out any wiring. Installation couldn’t be easier, with a kit provided to stick these sensors to the windows you want securing.

If the sensors are breached by kids or anyone else trying to access the pool, a piercing siren sounds, more than loud enough to alert you to the intruder.

While most user reviews for this pool alarm sing its praises, we found multiple complaints about the poor quality of the instructions provided. If you are not too proficient at DIY and you have never used door and window sensors before, this could be off-putting.

Global giant GE offers a value-loaded pack of 12 sensors. Even better, these things are priced very reasonably. Pool maintenance and upkeep is expensive enough, so every little extra counts.

Like all the best pool alarms, this set doesn’t require any wiring at all. Installing the sensors is as easy as sticking them to the windows or doors in question. This is where one of the problems with these sensors lies, though. A handful of disgruntled customers report the adhesive being too weak to keep the sensors in place over the long haul.

Everything you need for installation is included, though, and you won’t need to bother about any third-party mounting hardware either.

Choose from several settings with the option of either a chime or alarm to alert you if the door or window onto your swimming pool is opened.

The sensor will trigger the siren with very light intrusions of as little as 15 pounds. This makes it a class-leading pool alarm in this respect.
