Angelcare AC420 Review (2022)

Overview of the Angelcare AC420

The Angelcare AC420 was designed to provide parents with some peace of mind. The sound monitor is manufactured by Angelcare, who has been delivering unique and high-quality baby products designed to keep baby’s safe since 1977. The Angelcare audio monitor allows parents to hear everything going in the room with high-quality sound delivery.

Although the manufacturer has discontinued the Angelcare AC420, you can still purchase replacement parts through Angelcare for the original unit. The AC420, which delivers sound only, has been replaced by Angelcare with monitors that track baby’s breathing and provide video in addition to the sound, such as the Angelcare AC517 Baby Breathing Monitor with Video.

When purchasing an Angelcare AC420 Sound Monitor, you will receive a parent unit, a baby unit, and a docking/power station for the parent unit.

Commonly Asked Questions Before Buying a Sound Monitor

New and experienced parents alike love knowing what their baby is doing and that they are safe, even when they are just sleeping in the next room. A baby monitor is designed to provide parents with the peace of mind that they need to ensure their baby is still safe even if they are separated between two rooms.

These sound monitors detect any noise your baby makes when you aren’t in the room with them, alerting you to what it is your baby needs.

Consider the following features when shopping around for a good baby monitor:

Rechargeable Batteries

If you are like most parents, you will leave your baby monitor and its handset on at all times. If your baby monitor uses ordinary batteries, you will find yourself having to replace them often, which is not very cost-effective. Look for a baby monitor you can plug in or one that uses rechargeable batteries.

Sound Activated

You don’t want a baby monitor that keeps the speaker on at all times. Instead, find one that only turns the speaker on when a cry is detected, also known as VOX baby monitor or one with Eco Mode. Monitors that don’t provide sound activation frequently play ambient noise all night, including air conditioners running in the room or other background sounds.

Light Up Indicator

Sometimes you might mute the sound volume on the baby monitor or turn it down for some reason. In those cases, you want a monitor that provides a light-up indicator that alerts you to sound going on in your baby’s room even on mute. The light-up indicator allows you some night vision to visually monitor the noise your baby is making.

Interference Filters for Sound

Crystal clear sound from the handset is important because it allows you to hear what is going on in the room. Background noise and various ambient noises are distracting when picked up and amplified by a sound monitor, as it interferes with what you are trying to listen to. The best monitors offer a sound activation feature that will filter out the unnecessary noise.

Angelcare AC420 Review: Features

Here is a closer look at the features offered with the Angelcare Sound Monitor.

  • Ease of Use: The Angelcare AC420 Baby Monitor is its easy use. It’s easier to use than other Angelcare Baby Monitors, despite the variety of features it comes with. Setting up the unit is simple, just plug it in and turn it on.

    Both channel and volume control are located on the parent unit’s front, and the display is easy to read and understand. The display shows channel, temperature, battery level, and volume level.

  • Sound: You want crystal clear sound with a baby monitor, and Angelcare claims that is what they provide. The parent unit offers a maximum volume of 99.9 decibels.

    The problem is when it’s maxed out and even a little lower, the sound is a bit distorted, and it struggles to continually transmit sounds. The lower volumes provide clear sound, but it still cuts in and out at times.

  • Range: Angelcare claims the range for the AC420 is 820 feet if the two units have a line of sight.

    When tested outdoors, this claim held up to about 900 feet, but static enters the sound transmission around 650 feet. At 900 feet, the two units’ signal is lost completely, but it starts alerting to being out of range around 650 feet.

    Inside Angelcare claims, it has a range of up to 328 feet, but that isn’t entirely accurate. Tests done on the units show that the number of walls and how far apart the units are from each other play a factor in how far and long range the sound transmits.

    Certain appliances also interfere with the monitor’s ability to transmit sound. On average, the distance inside for clear transmission is a little less than 100 feet.
  • Night Light: The Nursery Unit, which remains in the baby’s room, comes with a night light feature. The light is controlled by the top button on the nursery unit; simply press it to turn the night light on or off.

    Having the night light on the nursery unit produces enough light for you to quickly peek in on the baby without disturbing their sleep cycle or potentially waking them up by turning on the bedroom light. It also eliminates the need for plugging in a separate night light.

  • Battery Life: When using AAA batteries inside the handheld unit, you can expect an average life of 30 hours. Alkaline batteries are required for the parent unit, while the unit in the baby’s room plugs into the wall.

    Although the parent unit is portable, it gets expensive having to replace the batteries, as rechargeable ones are not recommended. Another option is to purchase rechargeable AAA, but you still have to spend time recharging them in between.

  • Additional Features: Other notable features that come with the Angelcare AC420 is a low battery indicator and the ability to use batteries in the child unit as a backup power source.

    The AC420 offers an out of range alert, which will start beeping when the parent unit is out of range. Mute turns off all sounds, but the sound level indicator light allows you to visually monitor the noise level.

    Most importantly, the Angelcare AC420 offers adjustable mic sensitivity and sound activation. The adjustable mix sensitivity allows you to set the amount of noise the mic picks up to help you reduce the interference of ambient noise, such as the heater running.

    The sound activation only picks up the baby’s sound talking, crying, or otherwise making noise, so the monitor doesn’t alert for every little noise.

As with all of the sound monitors we have previously reviewed, it is important to list some alternatives.
