To use, simply place the Pool Patrol PA-30 pool alarm in any pool that measures 40 feet long by 20 feet wide or smaller (use multiple alarms for larger pools). With a low weight threshold of 15 pounds at its most sensitive setting, this Pool Patrol alarm uses a wave-detecting sensor to catch most pool entries.

When a large-enough wave hits the sensor, the onboard alarm goes off and sends a signal to the in-house remote receiver. Both the sensor and the receiver sound a loud alarm (over 90 decibels), and the remote receiver has a 200-foot range to notify adults of an unwanted entry. To reduce false alarms, simply twist the alarm to adjust the sensitivity.

Best For Sliding Doors

The Best Pool Alarms Option: Techko Pool Entry Gate Alarm

Sliding glass or screen doors that access the pool area can be difficult to arm because most door alarms have only one sensor, which must be removed or disabled to keep the door open. This weather-resistant door alarm from Techko features two sensors to solve the problem.

When installing the alarm on a screened sliding door, place one sensor on the glass door and the other on the screen door. When one of the two doors is closed, the sensor won’t sound, allowing you to leave the screen door closed and the sliding door open.

Once installed, this weather-resistant alarm is always monitoring. A bypass button gives adults 8 to 12 seconds to pass through the door without sounding the 110-decibel alarm.

The alarm detects motion in the water to trigger the alarm, which sets off an onboard and remote receiver alarm that works within 50 feet of the sensor. When it’s time to swim, activate swim mode to silence the alarm. If no movement is detected for 10 minutes, the pool alarm reactivates automatically.

Also Consider

The Best Pool Alarms Option: Poolguard DAPT-2 Water Hazard Pool Door Alarm

The weakest link of any pool area is its gate, which is why it’s wise to consider this Poolguard alarm. It can be installed on any outdoor or indoor gate, door, or screen and provides continuous monitoring except for the brief time when the pass-through button is activated.

If the pool gate is accidentally left open, the alarm sounds an 85-decibel siren after 7 seconds. The delay gives adults time to press the pass-through switch, so the alarm won’t automatically chime as soon as the door is opened. The delayed siren is designed to prevent false alarms.

Product Specs

  • Maximum pool size: Unlimited
  • Decibel level: 85 decibels


  • Will not take up a lot of space on a wall, fence, or pool gate

What to Consider When Choosing a Pool Alarm

Before buying a pool alarm, check local regulations. In some areas, certain types of pool alarms are mandatory (for example, a gate alarm). Begin by purchasing any mandatory alarms and add to the system from there. A pool alarm should be used in addition to other layers of protection, such as a fence, locking gate, safety cover, and adult supervision.

Types of Pool Alarms

The best pool alarm for a home depends not only on local regulations but also on the desired safety features and needs. Many homes combine pool alarms to create a fail-safe safety plan. Choose from the different types of pool alarms: standard, entry, or gate.

Standard Pool-Entry Alarms

A pool-entry alarm, which senses when someone or something enters the pool, contains a surface wave detection sensor that’s triggered when the water is disturbed. Pool-entry alarms float in the water or attach to the pool’s edge. Floating pool-entry alarms are not permanent and must be lifted in and out of the pool every time they’re used.

Poolside alarms, which install on the edge of the pool, contain a sensor arm that extends into the water to sense water movement. They can be a permanent or removable solution. To disable the alarm, some must be lifted from the water, while others have a “swim mode” that pauses the alarm when someone is in the pool. Some alarms must be reset after each use, but others automatically switch back on once the water is still.

Some alarms also have infrared motion detection, which operates like a motion-detecting burglar alarm to alert when triggered by a person or pet.

Gate Alarms

Gate alarms are designed for use with a fenced-in pool perimeter to sound an alert if anyone accesses the pool area. The best pool door alarms can be installed onto pool fence gates, sliding glass doors, or windows. These alarms blare a loud alarm if the threshold is compromised. However, since they can’t sense if someone actually enters the pool, gate alarms are often used alongside them.

In some municipalities, gate alarms are required by law, so check local bylaws and requirements. Gate alarms also don’t replace a gate lock; instead, they should be used together.

User-Entry Alarms

User-entry alarms are a wearable alarm system designed for children, pets, or adults who represent a safety risk. These alarms have two parts: a wristband or collar with a sensor and a base station. The sensor portion straps to a person’s wrist or around a pet’s neck and locks with a mechanism that only an adult can open. If the sensor gets wet, the base station sounds the alarm to alert nearby adults. User-entry alarms only protect those wearing a sensor.

Type of Pools

Pool alarms work for inground and/or above-ground pools. Since they don’t install or sit in the water, gate-entry alarms and user-entry alarms are suitable for all pool types. Most floating pool-entry alarms are suitable for both types.

Specific pool-entry alarms can be limited to inground pools or above-ground pools (including quick-set, soft-sided, or portable pools). Read the manufacturer’s recommendations to determine the correct pool type and installation requirements. Installing a pool alarm in the wrong type of pool may be dangerous.

Ease of Use

The best pool alarms are easy to use. When considering ease of use, determine the alarm’s ease of installation and how it arms and disarms.

Ease of installation typically depends on the pool alarm type. Floating pool-entry alarms and user-entry alarms are the easiest to install. Permanent pool-entry alarms and gate alarms usually require a few steps, but they stay in place for a long time.

Arming and disarming the alarm also vary depending on the alarm type. For example, floating alarms must be removed from the pool, while gate alarms or permanent pool-entry alarms must be manually switched on or off. Some pool-entry alarms have a convenient swim mode, which automatically turns on the alarm again after the water is still. The best pool alarm options have tamper guards and extra safety features so curious kids can’t disable the alarm.


Most pool-entry alarms have a specific sensing range, often determined by the largest recommended pool size. Larger pools may require multiple sensors.

When choosing a pool-entry alarm, consider its weight-sensing threshold. Pool-entry alarms only detect objects over a certain weight, usually starting at around 10 to 20 pounds, which is a critical consideration in homes with small pets that weigh less than that.

Some pool alarms include a remote alarm receiver to plug inside the home that adds an extra layer of safety, setting off the alarm even when no one is near the pool.

Alarm Volume

A pool alarm is only as good as its notification system, and its alarm should be loud enough to notify someone inside the house. Even louder versions can notify neighbors.

The chime on the average alarm clock is about 70 to 80 decibels, and a pool alarm should reach the same decibel level or even higher.

For remote receiver alarms, 80 or more decibels is suitable. Look for even louder options for those without a remote receiver because someone inside the home must hear the outdoor pool alarm. Most pool alarms also list the decibel rating in relation to distance.

Smart Control

A smart pool alarm, which connects via Wi-Fi or Bluetooth, allows you to control, monitor, or receive notifications through a smartphone. Smart control is most commonly provided for perimeter alarms like gate or doorway alarms, which often connect to a home security system.

Very few pool-entry alarms have smart controls, but a few are available. They usually connect to a smartphone for simple tasks, such as monitoring battery levels or setting various functions.


For pool owners, pool safety is of the utmost importance. A pool alarm plays one part in preventing dangerous pool-related accidents, making your family safer and providing peace of mind. Ahead are some frequently asked questions along with their answers to help you install and use your new pool alarm.

Q. Where do I put a pool alarm?

Installation location depends on the pool alarm type, so follow the manufacturer’s directions as to where to install it. However, most pool alarms should be placed where adults, children, pets, and wildlife could enter the pool or the pool area, quickly detecting anything or anyone who could fall in.

Q. How much does it cost to install a pool alarm?

Most pool alarms can be installed by the owner. Many installations don’t require tools and come with mounting hardware that most DIYers or first timers can install themselves.

Q. Is there a law that you have to have a fence around the pool?

In some areas, laws mandate fencing and gate alarms around residential pools. Check your local laws to determine if these rules apply to your home. No matter the laws, those with pets and children will want to consider having a fence around their pool for added peace of mind.

Q. Does a pool alarm have a camera feature?

Most pool alarms don’t have cameras. Those who want added security might want to install a security camera alongside their pool alarm to have eyes and ears on the pool.

Q. How does a pool alarm work?

A pool alarm detects unwanted access to the pool, whether it’s a perimeter breach, water displacement, or water contact, and sounds an alarm to notify you of a possible hazard.
