8 Best Wireless Doorbells, Alarms and Monitors

Wireless electronic door monitors, some originally intended for home security use, may be helpful when a person you care for begins to leave home alone, raising the risk of wandering and getting lost. A door monitor is one way of providing a remote caregiver alert that an outside door has been opened. The remote unit may be either battery operated (for portability) or designed to plug into an electrical outlet.

How do the Wireless Doorbells & Monitors Work

These monitors consist of 2 units:

1. The transmitter- mounted on the door and door frame with double-sided tape or screws (included with the products we tested). You need to make sure the door monitor transmitter and its side magnet are placed correctly (no more than 1/4 inch apart and properly lined up) or the product will not work.

2. The remote receiver, which provides an alert to the caregiver- this is plugged into a chosen location or carried with you, depending on the model.

When a monitored door is opened, the transmitter sends a signal to the receiver which provides an alert. You can purchase extra door transmitters for areas of the home that may also need monitoring, like the basement stairs and the front and back doors. You can also use these monitors on a refrigerator door, medicine cabinet, or kitchen cabinet door.

Main differences among the models:

  • Volume control and type of alert (chime, alarm or vibration)
  • Transmission range from the door to your receiver (75 to 150 feet)
  • How the alert is turned off (automatically or manually at the door)
  • Plug-in or portable (battery-operated) receiver for caregiver alerts.

An alert may allow you to get to the person’s side in time to accompany them outside or redirect the person from leaving home to another activity. Be sure to test the limits before depending on the device!

Make sure to check the transmission range (between the door and the receiver) may be lower than stated by the manufacturer, depending on the wall thickness and other environmental interference.

Also you should be aware that the alerts take one or two seconds to sound after the door has opened, depending on the model and the type of alert chosen. If the person is in a rush to get out the door, this type of alert may not give you enough advance notice.

Often times there are no low battery warnings on the door transmitter part and the batteries may need to be changed every few months, depending on use (see manufacturer’s instructions). You’ll need to check often to make sure the unit is working and not rely solely on this device to keep a person from wandering (or other unsafe activities).

Door Alarms for Alzheimer and Dementia Patients

As we all know, keeping an eye on a Alzheimer or dementia sufferer can be a daunting task. The danger that they wander out of the door and get lost is always there. That is why it is crucial you get to know the care receiver’s habits as they are all different.

Some people like to go wandering after they read their morning newspaper, others do so after they have had their dinner. Often times those habits are so ingrained in their previous lives that they will be impossible to change.

This is where the door alarms come in. They can be helpful in keeping  the track on your loved one. You may want to use this product along others, e.g., high and/or low sliding locks or a standard chain lock installed high or low. A chain lock may give you more time to get to the door, as the alert will sound when the door is partially opened, but the chain lock must be removed before they can exit.

These systems are not fail-proof and may not always work (even with charged batteries), so use multiple strategies when trying to prevent falls or wandering.

Below you’ll find door monitors that we’ve tested along with specific Pros and Cons for each product. We only tested products that offer a remote alert option, as alerts that only sound at the door can be upsetting to individuals with dementia.

You can also use motion sensors near the door to monitor the activity of the person you care for.

1.Wireless Door Monitor with Plug-In Caregiver Receiver Alert ( Lamson Home Care)

This wireless door monitor system comes with a battery-operated door transmitter and a plug-in caregiver receiver for alerts (plugs into a standard wall outlet). The manufacturer claims that transmission range is 150 feet.

The battery is included and already installed in the transmitter.


  • Pleasant Chime. When set on CHIME and a monitored door is opened, the tone or melody you’ve chosen sounds for one to five seconds and then automatically shuts off. (There is also an alarm sound setting.)
  • Caregiver alert volume control – low and high (though the switch is not labeled on the alert device). Volume for chime and alarm provides comfortable (not deafening) tones.
  • You can purchase additional units (door transmitter or remote caregiver receiver) if you want additional coverage.


  • When set on Alarm, there is a two-second delay for the alarm to sound, which may not be enough advance notice.
  • When set on the ALARM tone and a monitored door is opened, the remote caregiver receiver sounds an alarm for four minutes or it must be manually turned off at the door transmitter by switching the setting to the Chime position. Then you must switch it back to the alarm setting to continue using the alarm setting, as there is no on/off setting.
  • You may need several caregiver alerts in different locations to hear the alert, depending on the size of your home.
  • The plug-in caregiver receiver is for indoor use only. You can’t take it into the garden, for example. (Depending on environmental conditions, a battery- operated device may work outdoors.)

Tools Needed

  • Flathead screwdriver
  • Small Phillips head screwdriver

2. Wireless Door Monitor with Battery-Operated Caregiver Receiver Alert (SafeGuard)

This wireless door monitor system comes with a battery-operated door transmitter and a battery-operated caregiver receiver that clips onto a belt or waistband. The manufacturer claims that the transmission range is up to 100 feet. The alarm sounds for as long as the door is open and then automatically turns off. You can have up to three door monitors using one remote caregiver receiver in the same house, but the components are not sold separately; the monitor and the receiver are only sold as a package. 9V battery is not included!


  • Two alerts to choose from – vibrating or audio alert
  • It’s portable – you can take the caregiver receiver with you throughout the house, and even outdoors, as long as you stay within the 100-foot transmission range. Test to make sure you can get the signal, as transmission ranges vary depending on environmental conditions.


  • The audio alert is called a “chime” by the manufacturer. In reality, its a high pitched beeping sound.
  • There is no volume control – unfortunate as the alarm sound can be a bit jarring.
  • Although the vibrate alert is a nice option, you’ll need to test each time you want to use this function, as your sensitivity to vibration can be influenced by the clothing you are wearing and how close to your body the receiver is placed.
