What to Consider When Choosing the Best Barking Dog Alarm

There are several features to consider when shopping for the best barking dog security devices for your home. To ensure the alarm will effectively detect and dissuade people, consider the alarm’s range and sensitivity, volume level, sound modes, installation and connectivity options, and any additional features.

Range and Sensitivity

The best barking dog alarm units have a reliable detection system, with a high-enough sensitivity and range to detect intruders. Many barking dog alarms are placed indoors and are able to detect movement through walls and doors to catch any intruders lurking around the home. A few units come in two pieces, with a separate sensor placed outdoors while the alarm system sits indoors.

Barking dog alarms usually have a range between 10 and 30 feet, but some devices with outdoor sensors have a much larger range of up to 1,000 feet. To choose a suitable range, consider the area that needs monitoring: Some homes need a much smaller range (for example, monitoring the front step of a townhouse), while others might require a larger range to signal any human or animal intruders wandering the yard.

An alarm that is too sensitive might disturb the household or neighbors, while one that is not sensitive enough won’t activate when it needs to. To offer more flexibility, it’s best to buy a unit with an adjustable range or sensitivity, which allows users to set their own preferences.


A good alarm is loud enough to scare away animal and human intruders—broadcasting the sound through walls, windows, and doors—but quiet enough to not disturb neighbors. Many alarms advertise their decibel level, and the ideal range is between 100 and 115 decibels. This decibel level is comparable to the maximum volume of most personal listening devices or a loud entertainment venue (such as a concert or bar).

Along with a loud-enough volume, the top barking dog alarm models also have decent sound quality. The best way to gauge the sound quality is by reading online reviews. The audio should sound realistic, and the speaker should not create any tinny, rattling, or artificial sounds.


The simplest barking dog alarm system options have one mode, playing an angry dog barking sound whenever they detect motion. There are also alarms that change the volume or frequency of the barking audio as people get closer to make it sound more realistic. Other alarms have several modes to suit different uses.

Common additional modes include a doorbell mode, siren mode, and other options, such as calming nature sounds. The sharp sound of a dog barking can be startling or irritating to approaching guests or to people inside the home, so having the option for other sounds is useful. A doorbell sound or nature noises can notify occupants of someone approaching without setting off the barking audio.

Installation and Connectivity 

A good barking dog alarm system is easy to install: Most units are just plug-and-place options that need to be plugged into an alternating current (AC) outlet and placed in a preferred location. Some options can also be wall-mounted. While most barking dog alarms are AC-powered, a few offer a battery-only mode or the option for a battery backup in case of a power outage.

Barking dog alarms come in all-in-one units, with the sensor and alarm in one piece, or in two-piece units, with a separate sensor and alarm system. Some two-piece units allow users to place the sensor outdoors, which allows for more accurate motion detection. If the alarm is being installed outdoors, look for a waterproof or water-resistant construction (depending on whether the installation location is fully or partially exposed).

Most barking dog alarms have onboard controls, but a few also come with a wireless remote to activate, silence, or adjust the alarm from afar.

Extra Features 

Additional features can make a barking dog security system even more safe and convenient. Some alarms allow users to use their own recording, which makes it easy to switch up the audio or add longer barking recording loops and less likely for intruders to catch on to the alarm system.

Other alarm security products can also take advantage of barking dog audio. Products such as security bars can play a barking dog noise when intruders attempt to twist a doorknob or open a door.

Although many barking dog alarms are designed to deter human intruders, a few are targeted toward pest animals. These alarms often are designed to be installed outdoors and can include additional features, such as ultrasonic repellers or flashing light-emitting diode (LED) lights to deter neighborhood cats and wandering raccoons or deer. Some of these outdoor devices harness solar power to make them even more low maintenance.

Looking for a cheap solution to deter neighborhood kids or racoons from the front porch? This multiuse, motion-activated audio player is an affordable option and is simpler than traditional barking dog alarms: It has a motion sensor that detects movement, which triggers it to play the chosen audio.

Users upload their own audio, making this unit more flexible than some models. Users can upload the sound of their own dog barking or a different audio altogether, such as alarm sounds or a clip of humans talking, to make intruders think someone is home.
