Buying guide for best pool alarms

Ready to buy now? Shop the best:

A backyard pool provides plenty of fun and healthy exercise for the whole family, but it can also pose a serious risk to unattended children and pets. A child or pet that falls into the pool can drown in a matter of minutes if no one is around to pull them out. That’s why a pool alarm is essential for every pool. Even if you don’t have kids or pets of your own, you want to protect family and friends and any young neighbors who wander into your yard. 

There are several types of pool alarms, but they all provide an audible alert (and, in some cases, other notifications) to let you know when someone has entered your pool area or entered the water. For increased security, you can pair different types of alarms so you don’t miss any activity in or around your pool. 

But for a pool alarm to be effective, you must be able to hear it when you’re inside the house. If your pool is some distance from the house, the alarm must be extremely loud or it might not be audible across a large yard. Many alarms are also designed to reduce the risk of false alerts, such as the alarm going off when a strong gust of wind blows across the water or an automatic pool cleaner is working. Our favorite is the SwamCam Pool Alarm Camera System.

What to know before buying a pool alarm

Pool type

Whether you have an in-ground or aboveground pool, you’ll want to be sure that the alarm you choose is compatible with your type of pool. This is especially important if you’re choosing an alarm that mounts to the pool wall. It might be more difficult to mount an alarm to a round wall than a straight wall.

Alarm type

Wall/fence-mounted alarms: These pool alarms provide a simple solution if your goal is to keep intruders out of your pool area. Opening the gate triggers the alarm, so you’ll know right away if someone is trying to break in. However, these alarms can be easily thwarted if the intruder simply jumps over the fence. The Poolguard PGRM-2 In-Ground Pool Alarm and SwamCam Pool Alarm Camera are both wall-mounted units.

Personal immersion detectors: Parents interested in keeping young children or pets safe around the pool might want to invest in a personal immersion detector. A child wears a wristband (which can also be attached to a pet’s collar) that communicates with an alarm base unit. If a child or pet goes in the pool, the alarm is automatically triggered so that you can come to the rescue.

Pool-mounted alarms: These alarms can be mounted to the pool wall or float on the water with a tether connecting them to the edge. The alarm sounds when it senses waves or a substantial weight entering the water. Some underwater pool-mounted alarms detect subsurface movements. One of these is a smart choice if you’re interested in an alarm that can both guard against intruders and alert you to anyone who may accidentally fall in the pool. The Poolguard PGRM-2 In-Ground Pool Alarm is a pool-mounted alarm, while the Lifebuoy BCONE System Pool Alarm is a good example of a floating alarm device.

Alarm sensitivity

A pool alarm is a useful device but not if it’s responding to every leaf and twig that falls in the water. Too many false alarms could make you less inclined to use it. Manufacturers have found a way around this by instituting different sensitivity levels. 

Most alarms are set up so that they won’t sound unless something that weighs at least 15 to 20 pounds enters the pool. This should be large enough to detect most pets and young children while avoiding false alarms from leaves or other debris. The best pool alarms let you adjust the sensitivity level to minimize false alarms.

Our top pick, the Lifebuoy BCONE System Pool Alarm, and Pool Patrol PA-30 Pool Alarm both have multiple sensitivity levels. The SwamCam Pool Alarm Camera does not offer adjustable sensitivity levels because it utilizes AI for human detection and allows customization of the danger-detection zone.

Range

If you’re purchasing multiple alarms or a pool alarm with multiple components, such as a personal immersion detector, it likely has a base that sits outside the immediate pool area in a place where you can hear it if it sounds. In that case, you need to pay attention to the alarm’s range so you don’t position the alarm and base too far apart. Too far apart and the system may not work properly.

Some pool alarms connect to an app on your phone and automatically notify you if the alarm goes off even if you’re not at home when it happens. This is a nice option if you’d like to keep an eye on your home when you’re traveling.

The Lifebuoy BCONE System Pool Alarm does not have a specified range, but users can connect up to four devices for broader coverage. The Poolguard PGRM-2 In-Ground Pool Alarm works with pools up to 800 square feet. The Pool Patrol PA-30 Pool Alarm requires a 200-foot line-of-sight distance for the remote receiver, and the SwamCam Pool Alarm Camera covers an area up to 35 feet away in every direction of its view.

Controls

Some pool alarms include a remote that enables you to turn off the alarm. Others require you to turn off the alarm at the base unit inside your home or at the alarm itself. A remote isn’t an essential feature, but it’s certainly convenient if your alarm isn’t within easy reach.

Additionally, you want your pool alarm to be loud enough to hear but not so loud that it wakes up the neighborhood in the middle of the night. Look for a pool alarm with an adjustable volume control.

The Lifebuoy BCONE System Pool Alarm can be controlled with the included remote, through the base unit or through the smartphone app. The PoolGuard PGRM-2 In-Ground Pool Alarm can only be controlled with the remote key fob, and the PoolGuard DAPT-2 Water Hazard Pool Door Alarm has a bypass feature for adults. The Pool Patrol PA-30 Pool Alarm’s remote receiver can be placed up to 200 feet away from the floating alarm unit. The SwamCam Pool Alarm Camera can be managed through the smartphone app, but it also comes with a digital remote keypad for arming and disarming the system.

Tips for using a pool alarm

  • Read the instruction manual first. Make sure that you understand how to use and maintain your pool alarm before you install it.
  • Know how to shut off the pool alarm. Teach all the adults in your household how to use the system to prevent false alarms. And always remember to turn the pool alarm back on when you’re finished enjoying the pool.
  • Replace the batteries in the pool alarm regularly. If your pool alarm uses batteries, be sure to replace the batteries on a regular basis to keep the alarm functioning properly.

How we analyzed 

We considered dozens of pool alarms, ultimately deciding to include models that are easy to install and have an excellent range. The best pool alarms have several positive customer reviews reporting high sensitivity for unauthorized entry. Plus, we considered both wall-mounted and pool-floating devices for added convenience.

FAQ

Q. How much do pool alarms cost? 

A. Pool alarms range in price from about $80 to $300, and most cost about $100 to $175. You can expect to pay more for an alarm with specialty features, such as an app that controls the alarm from anywhere. But if you only need a basic unit to alert you to unexpected pool users, you shouldn’t need to spend more than $200.

The cheapest of our top five picks is the Yardgard Door and Window Pool Alarm at $39. The Lifebuoy BCONE System Pool Alarm is the most expensive floating alarm at $395, while the Pool Patrol PA-30 Pool Alarm is a significantly cheaper alternative that costs $220. The PoolGuard DAPT-2 Water Hazard Pool Door Alarm is a more affordable option that costs $63. However, if you want advanced technology and smart features, you’ll have to spend $500 for the SwamCam Pool Alarm Camera.

Q. How much weight will set off a pool alarm?

A. That depends on the alarm. Most have adjustable sensitivity levels so you can control the amount of weight that sets it off. In general, pool alarms are set to go off if something that weighs about 15 to 20 pounds enters the pool.

Q. Can wind trigger a pool alarm?

A. If you have a pool alarm that’s triggered by waves on the water’s surface, wind could set off a false alarm. If this concerns you, you can try a pool alarm that sits below the water’s surface and picks up subsurface motion.

Q. Can pool alarms be used in hot tubs?

A. Many pool alarms should work in hot tubs. If you’re unsure, contact the manufacturer to find out.
